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.

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.

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.<\/p><p class=\"un-answer-meta\">Read next: <a href=\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-finish-approval\">How do you agree the expected quality of floor and wall finishes?<\/a><\/p><div class=\"un-answer-meta\"><a class=\"un-tag\" href=\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-floor-transitions\">Link to this question<\/a><a class=\"un-tag\" href=\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#antwoord-floor-transitions\">Link to this answer<\/a><\/div><\/div><\/details><details class=\"un-faq\" data-search-synonyms=\"floor laying plan direction flooring pattern cut pieces floor order cutting waste\" id=\"faq-floor-laying-plan\" itemprop=\"mainEntity\" itemscope=\"\" itemtype=\"https:\/\/schema.org\/Question\"><summary><span><\/span><span itemprop=\"name\">What belongs on a laying plan before flooring is ordered?<\/span><span aria-hidden=\"true\" class=\"un-sr\" id=\"vraag-floor-laying-plan\"><\/span><\/summary><div class=\"un-answer\" id=\"antwoord-floor-laying-plan\" itemprop=\"acceptedAnswer\" itemscope=\"\" itemtype=\"https:\/\/schema.org\/Answer\"><p itemprop=\"text\">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.<\/p><p itemprop=\"text\">Ask the installer to confirm that the layout and required joints suit the selected product.

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.<\/p><p itemprop=\"text\">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\u2019s requirements for storage and preparation rather than assuming every flooring product needs the same conditions.<\/p><p class=\"un-answer-meta\">Read more: <a href=\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-floor-choice\">How do you compare timber, PVC, laminate and tiles for one room?<\/a> \u00b7 <a href=\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-finish-approval\">How do you agree the expected quality of floor and wall finishes?<\/a><\/p><div class=\"un-answer-meta\"><a class=\"un-tag\" href=\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-floor-delivery-check\">Link to this question<\/a><a class=\"un-tag\" href=\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#antwoord-floor-delivery-check\">Link to this answer<\/a><\/div><\/div><\/details><details class=\"un-faq\" data-search-synonyms=\"skirting corners end pieces skirting door cupboard junction floating floor skirting fixing\" id=\"faq-skirting-details\" itemprop=\"mainEntity\" itemscope=\"\" itemtype=\"https:\/\/schema.org\/Question\"><summary><span><\/span><span itemprop=\"name\">Which skirting details should I agree besides colour and height?<\/span><span aria-hidden=\"true\" class=\"un-sr\" id=\"vraag-skirting-details\"><\/span><\/summary><div class=\"un-answer\" id=\"antwoord-skirting-details\" itemprop=\"acceptedAnswer\" itemscope=\"\" itemtype=\"https:\/\/schema.org\/Answer\"><p itemprop=\"text\">Treat skirting as the junction between the floor, wall and fitted furniture.

Identify any existing skirting to retain and who will make good damage caused by removal.<\/p><p itemprop=\"text\">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.<\/p><p class=\"un-answer-meta\">Read more: <a href=\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-floor-transitions\">How do you plan practical transitions between different floor finishes?<\/a> \u00b7 <a href=\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-finish-approval\">How do you agree the expected quality of floor and wall finishes?<\/a><\/p><div class=\"un-answer-meta\"><a class=\"un-tag\" href=\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-skirting-details\">Link to this question<\/a><a class=\"un-tag\" href=\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#antwoord-skirting-details\">Link to this answer<\/a><\/div><\/div><\/details><details class=\"un-faq\" data-search-synonyms=\"protect new floor building work floor covering remaining trades floor condition trade handover\" id=\"faq-protect-finished-floor\" itemprop=\"mainEntity\" itemscope=\"\" itemtype=\"https:\/\/schema.org\/Question\"><summary><span><\/span><span itemprop=\"name\">How should a new floor be protected while other finishing work continues?<\/span><span aria-hidden=\"true\" class=\"un-sr\" id=\"vraag-protect-finished-floor\"><\/span><\/summary><div class=\"un-answer\" id=\"antwoord-protect-finished-floor\" itemprop=\"acceptedAnswer\" itemscope=\"\" itemtype=\"https:\/\/schema.org\/Answer\"><p itemprop=\"text\">Before installation, agree which jobs will follow and which walking or delivery routes must remain open.

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.

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.<\/p><p itemprop=\"text\">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.<\/p><p itemprop=\"text\">Describe the desired outcome: less visible wear, a local repair or a different colour.

Quick-Step\u2019s 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 \u201csuitable for bathrooms\u201d description therefore does not answer whether the chosen product is permitted in every part of your bathroom.<\/p><p itemprop=\"text\">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.

A \u201cfloor renovation\u201d therefore needs a stated depth of work.<\/p><p itemprop=\"text\">A change of appearance differs from correcting an unsuitable base, a level conflict or damage.

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.

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.<\/p><p itemprop=\"text\">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 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.<\/p><p itemprop=\"text\">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.

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.

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.

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.

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.\"}},{\"@type\":\"Question\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-plaster-ready-for-paint\",\"name\":\"How should I record when new plaster is ready for painting?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#antwoord-plaster-ready-for-paint\",\"text\":\"Treat painting as a handover point rather than only a calendar date.

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.

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.\"}},{\"@type\":\"Question\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-paint-cleanability-expectations\",\"name\":\"Does scrub-resistant wall paint mean every stain is easy to remove?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#antwoord-paint-cleanability-expectations\",\"text\":\"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\u2019s 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 \u201cwashable\u201d description does not fully answer those questions. Compare the painter\u2019s or manufacturer\u2019s 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.\"}},{\"@type\":\"Question\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-wall-paint-touchup-scope\",\"name\":\"What should I agree if a wall-paint touch-up remains visible?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#antwoord-wall-paint-touchup-scope\",\"text\":\"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.\"}},{\"@type\":\"Question\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-laminate-water-resistance-scope\",\"name\":\"Does water-resistant laminate also mean it is permitted on my bathroom or shower floor?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#antwoord-laminate-water-resistance-scope\",\"text\":\"The label alone does not establish that.

A general \u201csuitable for bathrooms\u201d 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\u2019s 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.

Beneath it there may be an underlay, screed, heating, insulation and the supporting floor. A new finish does not automatically replace those layers. A \u201cfloor renovation\u201d 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.\"}},{\"@type\":\"Question\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-door-rebate-types\",\"name\":\"What is the difference between a non-rebated (flush-fitting) and a rebated internal door?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#antwoord-door-rebate-types\",\"text\":\"A non-rebated (flush-fitting) door leaf fits entirely within its 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\u2019s details and the new system\u2019s 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.\"}},{\"@type\":\"Question\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-glazed-door-glass-properties\",\"name\":\"Do frosted, toughened and laminated glass mean the same thing in an internal door?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#antwoord-glazed-door-glass-properties\",\"text\":\"No. Frosted or satin mainly describes visibility and appearance.

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.

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.\"}},{\"@type\":\"Question\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#vraag-primer-functions-and-system\",\"name\":\"Why are absorption-control, bonding and stain-isolating primers not interchangeable?\",\"acceptedAnswer\":{\"@type\":\"Answer\",\"@id\":\"https:\/\/unitn.nl\/en\/knowledge-center\/floors-walls-finishes\/#antwoord-primer-functions-and-system\",\"text\":\"A preparatory coating can serve different functions.

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.

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.
