Floors and walls: preparation and finish choices

First record the subfloor material and its condition. Check flatness, stability, movement, existing adhesive layers and moisture against the requirements of the proposed flooring system. Agree who measures, what preparation is needed and who accepts the substrate before installation. A new covering does not automatically correct a defective base. Keep the measurements and photographs with the material specification so the supplier and installer work from the same information.

Compare complete flooring systems against the same brief: daily wear, exposure to moisture, cleaning, repair options, impact sound and any underfloor heating. Ask for the required subfloor, installation method and care instructions for each product. View substantial samples in the room under daylight and artificial lighting. Include skirting and transition profiles in the comparison. This connects the visual choice to actual use and installation rather than relying on a photograph.

Check that the proposed flooring, underlay and adhesive are compatible with the heating system as a complete assembly. Assess the thermal resistance of all relevant layers rather than the visible finish alone. Ask the supplier to confirm product requirements and operating limits. Agree the heating commissioning procedure and checks before laying with the installer. The resulting thickness and junction details must also work with doors, thresholds and neighbouring floors.

Record the finished level in each room, including levelling, underlay, adhesive and the floor covering. Draw transitions at doorways and identify profiles, movement joints or changes in level required by the chosen systems. Check door clearance and junctions with stairs and fitted furniture. Resolve these details before ordering. A transition belongs in the floor design and cannot always be corrected neatly afterwards by adding a strip.

A laying plan shows how boards or tiles will be arranged before you order them. Start with measured room dimensions, including recesses and fixed elements. Mark the direction, pattern, starting line and edges where cut pieces will fall. Review views from the entrance and junctions with neighbouring rooms as well as the centre of the space.

Ask the installer to confirm that the layout and required joints suit the selected product. Record the approved drawing and who calculates the order quantity. Discuss cutting waste and spare material separately; one standard allowance will not necessarily suit every pattern or room.

Compare the delivery with the order: product, finish, dimensions, quantities and accompanying accessories. Keep packaging labels together and look for transport damage or visible differences. Ask the installer to check the material against the agreed sample and confirm whether variation between packs fits the product specification. A photograph of one board cannot establish the appearance of the whole floor.

Agree who will report discrepancies to the supplier and which packs should be set aside. Do not install questionable material before the response is clear. Also check the manufacturer’s requirements for storage and preparation rather than assuming every flooring product needs the same conditions.

Treat skirting as the junction between the floor, wall and fitted furniture. Specify its profile, material, height and finish, then show corners, end pieces, door frames and connections to cupboards. Check that low sockets and access points remain usable. Identify any existing skirting to retain and who will make good damage caused by removal.

Ask the supplier or installer to explain the fixing method and movement space required by the flooring system. Skirting should not accidentally restrain a floating floor. Record who finishes the skirting and prepares the adjoining wall, so these small but visible tasks do not fall between separate work packages.

Before installation, agree which jobs will follow and which walking or delivery routes must remain open. Ask the flooring installer when the surface can take traffic and which temporary protection suits the complete system. Do not automatically use whichever covering or tape happens to be available on site.

Identify who installs, checks and removes the protection. Consider work involving grit, paint or heavy components, and complete it before the final floor where practical. Photograph the floor together when responsibility passes between trades. This creates a useful reference for discussing later damage without assuming that every protective sheet is suitable for every surface.

Photograph the whole staircase and its junctions with the floor below and landing above. Give steps and visible features identifiable numbers. Record the existing covering where known, and report loose areas, wear, previous repairs and places that cause concern in daily use. Do not infer their cause or the stair’s load capacity from those observations.

Ask the contractor to survey the steps and edges and show how the proposed covering meets the first and last step. Include adjoining floors, doors, skirting, the handrail and fixings in the review. Record who will assess whether the selected system and its effect on using the stair are suitable before ordering.

Include a material sample, product reference and agreed care instructions in the decision. Agree access to the upper floor during the work and when the staircase may be used under the selected installation requirements. This information supports a focused quotation and assessment; it is not DIY approval of stair geometry, slip performance or fixing methods.

First have the existing floor product and surface finish identified. Look for a product label, invoice or spare board, and mention earlier sanding or maintenance treatments. Ask the flooring specialist what construction and available timber layer they find and which treatment it can accommodate. A wooden appearance or an old photograph is insufficient.

Distinguish refreshing the existing finish from sanding the floor back to bare wood. These options differ between products. MEISTER describes a renovation route for the Lindura finish while conventional parquet-style sanding is not possible. That example does not establish suitability for your floor.

Describe the desired outcome: less visible wear, a local repair or a different colour. Have the proposal explain what can and cannot change, the expected appearance of edges and repairs, and subsequent care and use conditions. If uncertain, agree a representative trial before treating the entire floor.

The label alone does not establish that. Quick-Step’s current laminate manual, dated July 2026, links moist-room use to HydroSeal and specific conditions, while excluding rooms with a built-in floor drain and showers. A general “suitable for bathrooms” description therefore does not answer whether the chosen product is permitted in every part of your bathroom.

For example, if you want the same timber appearance in a kitchen and a bathroom with a walk-in shower, give the supplier the exact product code and a plan marking the shower area and drain. Ask which current manual and conditions apply. Ask whether those conditions permit that product in this room; if they exclude it, ask for an appropriate alternative. Kitchen acceptance does not determine bathroom acceptance. Have the responsible specialists address the building’s waterproofing assembly and junctions separately.

Before ordering, also discuss the required edge finish and everyday care. The cited manual calls for spills to be removed immediately; a water-resistant label is no reason to leave puddles or use any wet-cleaning method. Keep the applicable product, installation and care instructions together, and resolve unclear conditions before fixing the floor choice.

The floor finish is the visible wearing surface, such as timber, laminate or tiles. Beneath it there may be an underlay, screed, heating, insulation and the supporting floor. A new finish does not automatically replace those layers. A “floor renovation” therefore needs a stated depth of work.

A change of appearance differs from correcting an unsuitable base, a level conflict or damage. Compare retaining a suitable base with repairing or replacing identified layers. Include final levels at doors and adjoining rooms. Floor finishes and underlays do not provide a universal cure for an unstable or damp base; the cause and complete assembly determine the necessary work.

A solid timber board consists of one wood layer. Engineered parquet has multiple layers with real timber at the surface; Quick-Step describes its parquet as a layered wood construction. Laminate uses a printed decor over a wood-fibre core beneath a protective surface. An oak appearance therefore does not establish a solid-oak top layer.

This distinction helps set realistic care and repair expectations. Sanding a printed decor does not reveal a renewed timber surface; refinishing real wood still depends on the exact product and condition. Then compare the complete system for the room, including moisture exposure, installation method and any heating. Layer count, thickness or the word “wood” alone does not establish universal suitability.

A floating finish forms a connected surface that is not bonded to the supporting base. In a bonded system, a specified adhesive connects the finish to the substrate. “Click” describes the connection between components; it does not establish which complete assembly is allowed for another product.

The choice affects preparation, height, underlay, movement and later removal. A floating system must retain the movement required by its product conditions; fixed heavy items must not inadvertently change that. A bonded system requires a compatible substrate and adhesive. Compare the permitted arrangement for the exact product. Noise, heating compatibility and suitability over an existing floor do not follow automatically from the method.

“Subfloor” may mean the existing supporting base, while underlay is the layer immediately beneath a floating finish. Underlay can serve different functions in the chosen flooring system, including walking sound, heat or moisture-related properties. Quick-Step consequently distinguishes underlays for different situations.

The correct combination matters more than maximum thickness or a “sound-reducing” label. A thermally insulating layer can differ from an arrangement for underfloor heating. Accommodating minor irregularities does not make every damaged, damp or unstable base suitable. The exact laminate and manual determine the permitted base, underlay and moisture provisions. For an acoustic requirement, request evidence for the complete combination rather than an isolated figure without application conditions.

A T or transition profile finishes the junction between floor surfaces and can cover a required separation. A reducer bridges a height difference. An end profile terminates the floor at an edge, such as a window or fixed fitting. Parquetvinyl distinguishes these functions in its range. Matching colours therefore do not make the profiles interchangeable.

Select for the actual floors, finished heights and required movement. The preferred visual shape must also suit the chosen system’s permitted junction. A profile is not a universal cure for incorrect floor levels or a missing movement joint. Include its section and visible position in the floor plan, and check door movement and use at the opening.

This describes the timber’s treatment, not whether the floor is solid or engineered. Lacquer provides a protective surface finish. For the parquet oil described in Bona’s Home brochure, protection works through the wood’s pores rather than forming the same lacquer film. A matt appearance alone does not identify the treatment.

The distinction matters for cleaning, maintenance and later repair. Follow the actual finish system’s instructions; a maintenance product for oiled timber is not automatically suitable for a lacquered floor. Different product build-ups also exist, so “oil” or “lacquer” does not answer every care question. Keep the product and finish details with the flooring choice, and match repair to the retained treatment rather than guessing from appearance.

Read more: How can I assess whether my timber floor can be refinished? · How can you avoid damaging new finishes when cleaning? · How do solid timber, engineered parquet and laminate differ?

Not exactly. Use class describes the intended application and intensity of use, distinguishing contexts such as domestic and commercial use. Abrasion class concerns a particular surface-wear test. EPLF identifies abrasion resistance as one factor in assessing laminate. One wear figure is therefore not the complete specification.

Compare the actual room and expected use with the current classification of the exact product. Also review water, heating, castor, underlay and care conditions. A use class does not promise a fixed lifetime, freedom from scratches or suitability for every bathroom. The product data and installation conditions must describe the same version; do not transfer a class from another collection.

Assess the existing surface first: is the coating sound, is the wall clean and is the substrate suitable for the paint system? Investigate damp patches and loose material before covering them. Specify repairs, cleaning, primer and finishing coats according to the product instructions. Approve a sample area for colour and sheen. Also record how adjoining floors, frames and fittings will be protected during preparation and painting.

Start with the problem: an uneven surface, space for services or an additional insulation build-up. Assess the existing wall and available room before comparing options. Consider total thickness, window and door reveals, fixing heavy items and access to services. A boarded lining should not conceal unresolved damp or damage. Record the complete build-up and have any required moisture and insulation details designed for the actual wall construction.

Read next: What should be checked before insulating an external wall internally?

Yes. Establish whether the crack affects only the finish or also the underlying construction. Record its location, pattern and any changes with dated photographs. If it grows, returns after repair or appears alongside other changes, have an appropriate specialist assess the possible cause before selecting a repair. Filling and repainting alone may hide the symptom without resolving it. Keep the assessment with the agreed finishing specification.

Read next: What should you record if a problem appears after handover?

Use an approved sample area and a concise finish schedule as the shared reference. Record the product, colour, sheen, laying pattern, grout colour, skirting and visible junctions. Agree the lighting and viewing conditions for inspection and the applicable product guidance. Photograph the sample but retain a physical reference where practical. Review work as it progresses so differences can be addressed before every surface has been completed.

Develop the finish schedule by room and surface. One example entry is: living room, wall W1 between door and window; colour from approved sample K03; product and sheen awaiting painter confirmation; window frame excluded; sample area P01 awaiting approval. Keep an unresolved choice marked as open so a colour name is not mistaken for approval of the complete paint system.

For each entry, add the work boundary, dated approval and current revision. Name the person who maintains changes and give the same version to everyone pricing or ordering from it. Record substrate condition and preparation separately. This keeps final choices distinguishable from items still requiring the contractor’s assessment.

Record each door leaf, frame, hinges, latch and visible damage. Identify what needs to improve: appearance, operation or its relationship with a new floor. Ask the contractor to assess what work the existing material can accommodate. Repainting a door and repairing a damaged frame are different tasks and should be described separately.

Compare retention and replacement using the same complete scope, including hardware, finishes and making good around the frame. Before altering anything, ask whether the door has a particular function with specific requirements. Record the selected approach for each opening, using a photograph and the agreed finished floor level as references.

A factory-lacquered door, an HPL surface and bare timber do not automatically take the same treatment. Berkvens publishes separate repainting guidance for its door types and advises against painting where suitable guidance for the door is unavailable. Identify the retained surface before treating repainting as a simple refresh. Include its coating system and the effect on hardware and junctions in the comparison; matching colour says nothing about the required preparation.

Decide how much light and visibility you want between rooms and when privacy matters. View the glazing and finish under the home’s lighting; a small sample does not show the full experience of a complete door. Draw its opening direction and check the space needed for the leaf, handle and nearby furniture.

Ask the door specialist to confirm a suitable door and glazing system, including fixings and any particular safety requirements. Request the product’s cleaning guidance and ask how the glass and hardware can later be accessed or replaced. Record the product, glazing, dimensions and finish together before finalising the opening or order.

Draw the panel layout on an elevation showing sockets, switches, grilles and existing access points. Include the thickness of both the panels and their support. Agree which components need adjustment or relocation and who carries out that work. A neat cut-out alone does not confirm that an installation remains usable or accessible.

Ask the contractor to assess the substrate and fixings and identify any sections that must remain removable. Keep a detail of each inspection opening and record how it is opened. Review a sample or the first installed panel before covering the whole wall, considering visible junctions and service access together.

Before the wall is closed, identify the positions of cupboards, a television, shelves or other fixtures. Provide the product, dimensions and intended use rather than weight alone. An item that projects from the wall or moves applies a different load from a flat picture.

Ask the wall contractor to select the board build-up, fixings and any reinforcement required by the actual system. Check whether the wall has particular restrictions. Record the installed provisions with measurements and photographs before they are concealed. Keep this information with the mounting drawing and have later fixing work checked against it, rather than relying on an arbitrary plug or universal rule.

Show lighting, grilles, detectors, curtain fixings and required access on one ceiling plan. Record positions, products and who supplies each connection or fitting. Check that the selected components fit the available space and remain accessible for maintenance. Include retained equipment so it is not accidentally covered.

Ask the installer and ceiling contractor to coordinate their work before closing and finishing the ceiling. Identify any fixing provision or inspection opening in advance rather than drilling exploratory holes after painting. Keep the final drawing and photographs of concealed provisions, clearly identifying what was actually installed and any changes from the original design.

Confirm dimensions once the junction with the window frame and finished wall is clear. Measure the opening and discuss depth, projection, edge treatment and visible joints. Review nearby elements with the contractor, including curtains, radiators, furniture and any window that opens inward.

Ask the supplier to confirm the support and fixing requirements of the selected material. Agree who measures and who releases the dimensions for manufacture. Record them on a drawing that includes the wall build-up and final junctions. This avoids ordering from a rough opening that may change during finishing, and makes responsibility for the final measurement clear.

Treat painting as a handover point rather than only a calendar date. Knauf requires gypsum plaster to be fully dry before paint is applied. The necessary preparation and assessment also depend on the plaster and selected paint system. Have the plasterer and painter confirm these starting conditions together.

For each wall or ceiling, record the product, application date, relevant observations and who assesses readiness for the next finish. One useful entry is: living room, wall W1, new gypsum plaster; painter to assess suitability and necessary preparation before release. Ask the trades which checks they use rather than agreeing a universal waiting period from thickness alone.

Link the start of painting to that confirmation. If further wet work is planned in the room or the assessment is outstanding, discuss the effect on subsequent activities. A lighter-looking patch or a surface that feels dry is not an agreed professional release. Keep the outcome with the programme and product information.

Have the junction developed as a separate detail before approving the appearance. A framed plasterboard wall and plastered masonry are different systems. Knauf explains that simply filling across such a junction can lead to cracking. One continuous colour does not automatically mean the underlying junction can also act as one surface.

For example, mark the boundary between old masonry and new plasterboard on a living-room wall elevation. Ask the wall builder and plasterer which junction suits the installed systems, whether a visible joint or profile remains, and how it meets the floor, ceiling and skirting. Add the agreed detail and a representative example to the finish schedule.

Identify who executes the detail and what information the painter needs to finish the boundary correctly. Discuss a wish for an uninterrupted surface before work begins; do not erase a necessary separation purely for appearance. Investigating an existing crack remains a separate question.

No. Scrub resistance and stain removal describe different things. Sigma makes this distinction in its cleaning protocol: a coating can withstand cleaning while a particular mark remains visible. Review the exact product’s care instructions and properties as well as its colour and sheen.

Describe the actual use of the location. A wall beside coat hooks, for example, is touched differently from a decorative wall above a cupboard. For the proposed paint, ask which everyday marks are normally removable, when the coating is ready for cleaning, and which products and tools are permitted. A general “washable” description does not fully answer those questions.

Compare the painter’s or manufacturer’s answers before selecting the product. Also agree what happens if a mark remains: further cleaning, touching up a small area and refinishing a larger surface are different decisions. Repeated harder scrubbing does not replace missing product instructions; have uncertainty about the surface assessed first.

Read more: How can you avoid damaging new finishes when cleaning? · How should I assess colours and materials before choosing them? · How do you agree the expected quality of floor and wall finishes?

First identify the difference: colour appearance, sheen, texture or the boundary between old and new work. The same colour code does not guarantee an identical appearance. Sigma identifies product texture, sheen, application and light among the factors behind colour differences. Have the painter compare the existing coating and products before another touch-up.

Mark the repair location on an overview photograph and keep the product, colour reference and available details of earlier treatment. Discuss a trial in an agreed location and review it when the applied coating is ready according to its instructions. Use the agreed lighting and normal viewing positions so everyone considers the same result.

Record the repair boundary you will accept if the trial remains visible: the spot alone, a defined wall section or the entire wall. Ask about preparation and the effect on adjoining finishes for each proposal. A small touch-up and a completely refinished wall are different scopes. Moisture, peeling paint or recurring damage first requires assessment of the cause.

A non-rebated (flush-fitting) door leaf fits entirely within its frame. A rebated leaf has a projecting edge that partly overlaps the frame. Berkvens describes different hanging arrangements for these types: conventional hinges for the cited non-rebated version and special lift-off hinges for the rebated version. This is a difference in junction and system, not merely appearance.

When replacing a leaf, its frame, dimensions, handing, hinge and latch positions must match. Two doors with the same stated width are not automatically interchangeable, and measuring conventions also differ. Use the existing opening’s details and the new system’s product guidance rather than inventing a conversion or removing an edge. A door with a particular performance function also retains the conditions of its complete assembly.

Read more: How can I decide which internal doors to retain and refurbish? · Which airflow routes should be checked after changing a layout or internal doors?

No. Frosted or satin mainly describes visibility and appearance. Toughened and laminated describe different glass constructions and breakage behaviour. Laminated glass combines panes with a polymer interlayer that can retain fragments after breakage. Toughened glass breaks into small pieces. A privacy finish therefore does not identify the safety construction.

Choose the light and privacy effect alongside a suitable complete door and glazing specification. Surface treatment, tint and safety construction can be combined; they are not interchangeable labels. Record the actual glass product and door leaf for the intended application. A sample or the words “safety glass” alone do not establish that the combination meets every project-specific requirement.

Read more: What should I specify before choosing a glazed internal door?

A stone-like appearance does not identify the material. Natural stone differs from a wood-based core with a decorative surface. WERZALIT, for example, describes a wood-and-resin core with a melamine-resin coating, including stone-effect decors. Compare the actual composition and edge treatment rather than only a photograph or colour name.

For either option, consider its location, water from plant pots, cleaning, visible ends and repair possibilities. Properties and permitted cleaners are product-specific. Junction materials also differ: Soudal highlights stone-compatible sealant to avoid staining natural stone. Use a physical sample and the care instructions in the decision. Support and fixing suitability remain separate parts of the measurement and installation assessment.

A preparatory coating can serve different functions. Within plaster systems, Knauf distinguishes controlling strong or uneven suction, bonding to a smooth base and limiting colour bleed from particular contamination. These are different substrate problems. The word “primer” does not mean that one product solves them all.

Select preparation as part of the full system: existing substrate, preparatory layer and intended plaster or paint. A gypsum-plaster primer is not automatically a primer for wall paint. Isolating an old stain does not remove an active moisture source either. A useful specification identifies the substrate problem and the corresponding product function; “one coat of primer” alone is insufficiently precise.

Read more: What needs to happen before painting an existing wall? · How should I record when new plaster is ready for painting?

The colour code is only one part of the appearance. Sheen changes light reflection; texture, application and the light source also affect perception. Sigma explains that a high-gloss product can therefore look different from a matt or satin product using the same colour reference. This does not necessarily mean the colour was mixed incorrectly.

Review the intended product and sheen together on a representative sample in the room. A matt wall and lacquered frame need not look identical despite sharing a code. Select sheen for the intended appearance, location and exact product properties. A sheen name alone does not predict scrub resistance, stain removal or technical suitability.

A light-coloured alkyd-resin coating can yellow indoors, particularly in places receiving little daylight. Sigma identifies this as a property of that coating type. The product matters: “white” describes the chosen colour, not every later colour change. Soiling, previous coatings and lighting can also affect the appearance.

Identify the existing product and binder before choosing another white finish. Compare intended interior use, compatibility with the retained coating and care information as well as the colour name. This general explanation does not diagnose one particular frame or establish whether workmanship is defective.

Read more: What needs to happen before painting an existing wall? · How can I decide which internal doors to retain and refurbish?

These terms describe different functions or appearances. A levelling coat brings a rough or uneven base into the intended plane. Smooth plaster provides a smooth surface for the selected subsequent finish. Textured decorative plaster such as spachtelputz has a visible grain. A smooth white wall and a coloured textured wall are therefore more than two colours of one finish.

Establish what the base requires before selecting the appearance. A finer or glossier finish can demand different preparation from a coarse texture. Identify whether the proposal includes levelling, a decorative final coat and painting. Review texture and lighting on a representative sample area; a product name alone does not describe the complete assembly.

Read more: When should you consider plastering versus a boarded lining? · How do you agree the expected quality of floor and wall finishes? · How should I record when new plaster is ready for painting?

The label alone does not establish that. “Wallpaper-ready”, “paint-ready” and the Dutch term “sausklaar” are not used uniformly. TBA explains this ambiguity and connects the intended substrate quality to its eventual covering. A surface intended for wallpaper may produce a different result when simply painted.

Compare the actual handover quality, intended paint or wall covering and included preparation. Identify whether local smoothing, sanding, filling and necessary priming belong to the next contract. Even a flat wall must suit the selected system; a label is not a moisture assessment. Agree the result and work boundary using a sample and explicit description rather than relying on the word “ready”.

Paper-faced plasterboard has a gypsum core with bonded paper facings. In gypsum-fibre board, gypsum and fibres form a homogeneous board; fermacell describes paper fibres among its ingredients. Both are used for interior linings, but they are different products with potentially different jointing, fixing and finishing requirements.

Compare the intended complete wall or ceiling, including framing, layers, board variant and finish. A statement about one board does not establish the fire, acoustic or load performance of every assembly using it. Heavy fixtures and moisture-exposed locations require confirmation for the exact system and application. The board’s colour or the word “plasterboard” alone is not an adequate specification.

Read more: When should you consider plastering versus a boarded lining? · What should I arrange for heavy fixtures before a plasterboard wall is closed? · What should I agree where a new plasterboard wall meets an existing plastered wall?

Q1 to Q4 describe progressively developed surface finishes, not the wall’s strength or fire resistance. In Knauf’s table, Q1 is functional joint finishing without the same visual requirements as a smooth painted surface. In that table, Q2, Q3 and Q4 correspond to normal, high and very high visual expectations, with progressively developed surfaces.

Select a level for the actual coating or wall covering and lighting. Fine, glossy finishes and light travelling across the wall can reveal surface differences. A higher level does not promise invisibility under every light. Dutch A-to-F classes and European Q levels are also different tables. Identify the agreed table and description alongside the sample area and intended final finish.

The binders differ: cement-based grout and epoxy grout are different product types. The selection affects documented resistance and care. ARDEX, for example, describes water- and dirt-repellent properties for cement-based G10 and heavier chemical and mechanical exposure for its WA epoxy product. This does not mean every cement grout performs poorly with water or every epoxy grout resists every cleaner.

Compare the actual tile, joint application, exposure and permitted cleaning in the technical product information. A different colour or higher price does not establish the better choice for your bathroom. Confirm compatibility with natural stone or sensitive tile surfaces. Tile grout replaces neither a movement joint nor the waterproof assembly behind the tiling; those serve separate functions.

Cover skirting is a profile fitted over retained skirting rather than replacing it after removal. Orac describes these products alongside ordinary skirting. It can renew the appearance, but does not establish that the retained component or hidden base is sound.

Compare the complete section: existing height and thickness, internal capacity of the new profile and its added projection. At door frames, cabinets and radiators, the larger outer dimensions can affect appearance or use. Select the actual material and coating as well as the shape. A cover solution must not hide unexplained damp or required access, and must suit the floor’s movement provisions.

Read more: Which skirting details should I agree besides colour and height? · How do you plan practical transitions between different floor finishes?

First identify the panel core and visible surface. A timber effect, relief or classical moulding does not establish whether it is real timber, a wood-based board or a polymer product. Orac, for example, uses different polymers for decorative profiles and panels. The material, finish and complete product system determine its documented uses and treatment.

Compare relief, joints, edge treatment, cleaning, repainting and later replacement. Deep relief can look and clean differently from a flat sample. Request separate evidence if the panel must also perform acoustically or meet a particular fire or moisture brief. A slatted or decorative form does not establish those properties. Include the material in the wall detail so sockets and access points remain usable.

A plastered ceiling finishes a suitable supporting surface. A continuous-board ceiling uses boards finished as a surface rather than individually accessible tiles. A demountable system uses designed removable elements within a support grid. Knauf describes Contur D+, for example, as a demountable board ceiling. The choice therefore concerns construction and access as well as colour or smoothness.

Compare the intended appearance with available space and components above the ceiling. Removable elements can support access, while a continuous surface may need dedicated openings. Edges, joints, lighting and maintenance also affect the result. Confirm any acoustic or fire performance for the complete selected assembly; “gypsum ceiling” or a perforation pattern provides no universal assurance.

No. The application term does not identify the material. Machine-applied gypsum work adds plaster; decorative sprayed plaster can create a fine or coarse texture. Spray painting applies a coating. NOA describes these as different operations. A quotation saying only “spraying” therefore leaves the base and eventual surface unclear.

Compare the material, intended texture, necessary flatness and subsequent paint finish. Use a sample to show the difference. Spraying does not automatically make an unsuitable base suitable or establish which adjoining areas are protected and finished. Specify whether the scope includes preparation, plastering, decorative spraying, painting or a combination before comparing prices.
