Polyurethane finish — PU, in showroom shorthand — is the finish you reach for when you want a kitchen or wardrobe to feel like furniture, not joinery. It is also one of the most over-sold and under-explained interior finishes in the Indian market. This guide is built to fix that.
We'll walk through what PU finish actually is, how it is applied, what it should and should not cost in 2026, how it compares to laminate, acrylic, duco and membrane finishes, and which homes it makes sense for. If you have ever stood in a showroom and been told "sir, this is PU only" without quite knowing what that means — start here.
What is PU finish?
PU finish is short for polyurethane finish — a multi-coat liquid coating sprayed onto a primed and sanded surface to create a hard, seamless, paint-like skin. It is not paint and it is not laminate. It sits closer to automotive coating than to either: a hardened resin shell that cures chemically rather than just drying, bonded to the substrate beneath it.
How polyurethane protects furniture
Once cured, a PU coat is essentially a thin layer of plastic. It resists scratches, water, mild chemicals and UV light far better than melamine or traditional French polish. Because each successive coat fuses into the one below, the finish reads as a single continuous surface — no joints, no edge banding, no visible seams. This is the look people pay PU pricing to get.
How it differs from traditional polish
Traditional polish — melamine, NC lacquer, or wax-based polish — sits on top of the wood as a thin film and reveals the grain. PU does the opposite: it builds a thicker, opaque surface that hides the substrate entirely.
That is why PU on MDF or HDHMR looks the same as PU on plywood — you are paying for the finish, not the board underneath. Polish is for showing off wood. PU is for shaping a furniture surface to look exactly the way you want.
Why premium designers reach for PU
Three reasons. First, design freedom — PU can be tinted to any colour, any sheen, including custom mixes that no laminate brand will stock for a single client. Second, edges — PU wraps continuously around a shutter, so the front and the edge are the same material with no banding to peel. Third, hand-feel — a well-buffed matte PU has a soft, almost suede-like touch that laminate simply does not.
In one line
PU finish is a sprayed-on, chemically cured plastic coating that gives furniture a seamless, high-end painted look — at roughly two to four times the cost of premium laminate.
Types
"PU finish" is a category, not a single product. When you sign off on PU, you are picking on three axes at once: chemistry, packaging and application method. Each one affects price, finish quality and durability.
By chemistry: solvent-based vs water-based
Solvent-based PU
The default across most Indian factories. Harder finish, deeper gloss potential, better moisture resistance. The downside is strong fumes during application and a heavier VOC load, which is why a proper spray booth is non-negotiable.
Higher durability Strong fumes Most kitchens
Water-based PU
Newer to India and growing fast. Lower VOC, milder smell, faster surface dry. Slightly softer film than solvent PU, so it scratches a touch easier — but the gap narrows every year as the chemistry improves. Best for bedrooms, kid's rooms, and homes where ventilation is limited.
Low VOC Mild smell Bedrooms, kids' rooms
By packaging: single-component vs two-component
Single-component (1K) PU
Pre-mixed, ready to spray. Easier to apply, longer pot life, cheaper. But the cured film is less hard and less chemical-resistant than 2K. Acceptable for low-traffic areas like display units and wall panels.
Two-component (2K) PU
Resin and hardener mixed at the time of spraying. This is what you actually want on a kitchen or a wardrobe. The chemical cross-linking that happens after mixing is what gives 2K its scratch resistance, hardness and longevity. Almost all premium PU work in India is 2K.
By application method: spray, roller, brush
Spray is the only application method that produces a true PU finish. Roller and brush PU exist — usually in budget projects or for retouching — but they cannot produce the seamless, dust-free surface that PU is bought for. If a vendor quotes "PU finish" at laminate prices, ask how they're applying it. The answer is almost always brush or roller, and the result is closer to glorified enamel paint than to PU.
Gloss levels: from super matte to mirror gloss
The same PU resin, in the same colour, looks like a different material at different sheen levels. Gloss is measured on a 0–100 scale based on how much light the surface reflects at a 60-degree angle. Indian factories typically offer six tiers:
Super Matte0–5 GU
Matte5–15 GU
Satin15–35 GU
Semi Gloss35–70 GU
High Gloss70–90 GU
Mirror Gloss90+ GU

Textured PU
A separate category worth mentioning: textured PU adds a fine grain, suede or sandstone-like feel to the surface during the final coat. It is harder to apply, more expensive (roughly 15–25% over matte) and looks distinctly different in person than in photos. Worth specifying on one or two statement units — a tall pantry, an island front — rather than a whole kitchen.
Colours available
One of the strongest arguments for PU finish is colour. Unlike laminate, which restricts you to whatever the brand decided to print this year, PU can be tinted to almost any RAL or NCS code your designer specifies — usually within a 24-hour lab match.
White
The most-ordered shade. Pure white, warm white, off-white, ivory — small undertone shifts change the whole room.
Grey
From cool dove grey to deep cement. Hides daily wear better than white. Pairs with chrome or matte black hardware.
Black
Demands matte. Reads expensive when lit well, oppressive when not. Stunning on islands and tall units.
Wood-shade PU
PU tinted to mimic walnut, oak or teak. Softer than veneer, more consistent than wood-finish laminate.
Statement colours
Forest green, navy blue, burgundy, ochre. Where PU truly wins over laminate — custom shades, perfect colour match.
Metallic PU
Champagne, gun metal, brushed bronze. Specialty tier, 20–30% premium, best in small doses.
On custom colour matching. Most premium brands — ICA, Sirca, Milesi — will match a Pantone or RAL code with surprising accuracy. The catch is sample size: always insist on a 6"×6" sprayed sample on the actual board you're using, viewed in your home's lighting, before signing off the full job. A swatch on glossy paper will lie to you.
How it is applied: the 10-step process
Most clients never see this happen, which is exactly why PU pricing varies so wildly. A factory PU process should look like this — if your vendor skips three or more of these steps, you are paying PU prices for sub-PU quality.
Surface preparation
Boards are inspected, edges trimmed, and any defects (chips, knots, splinters) filled. The board's moisture content is checked — anything above 8% will cause adhesion problems later.
Day 1
Coarse sanding
An initial pass with 120-grit sandpaper to open the surface pores so primer can grip. Skipping this is the single most common cause of PU peeling later.
Day 1
Primer coat
A 2K polyurethane primer is sprayed evenly. Primer fills micro-pores in the board and creates a uniform base for the colour to sit on. Two coats minimum; three for darker shades.
Day 1–2
Putty filling
Any remaining low spots — screw holes, joinery gaps, MDF edge irregularities — are filled with PU-compatible putty. This is the step that separates a factory finish from a site finish.
Day 2
Intermediate sanding
The primed surface is sanded with 320-grit paper to level the primer and putty. Dust is blown off with compressed air. This step happens between every spray coat in a serious workshop.
Day 2
Base coat
The first tinted PU layer. Sprayed in a controlled, dust-free booth at the right viscosity. Two coats minimum, with sanding between them. By the end of this stage, the surface has its colour.
Day 3
Inspection and touch-up
Surface checked under angled light for orange peel, dust nibs, runs and pin holes. Defects are spot-sanded and re-sprayed before the final coat.
Day 3–4
Final top coat
The clear or tinted top coat is sprayed at the specified gloss level. This is the layer you actually see and touch. Done right, it lays down dead flat with no orange peel and no nibs.
Day 4
Curing
The chemistry of 2K PU finishes hardening for 48–72 hours after the final coat — and reaches full chemical hardness only after 7 days. Rushing delivery before curing completes is the second-biggest reason for PU complaints.
Day 5–7
Final buffing
Once cured, the surface is buffed to its final sheen — matte, satin or gloss — with progressively finer compounds. Only after this step should the units leave the factory.
Day 7
What this means for you
A proper PU job takes 5–7 working days per unit, minimum. If a vendor promises a fully PU-finished modular kitchen in three days, they are skipping curing — and your finish will scratch and peel within a year.
Where to use it in your home
PU finish makes sense anywhere you want a seamless painted look, where edges and joinery should disappear, and where moisture or daily wear demand a hard protective coat. It does not make sense everywhere — and choosing wisely is half the cost-saving.
Modular kitchens
The flagship use case. Shutters, tall units, island fronts, pantry doors — all classic PU territory. Recommended on the units you touch every day.
Wardrobes
Sliding and hinged. PU's seamless shutter face is what makes premium wardrobes feel premium. Worth the cost on master bedrooms; optional in kids' rooms.
TV & media units
One of the most photographed surfaces in any home. PU gives the seamless, joinery-free look that built-in TV units need to feel architectural.
Crockery & bar units
Where furniture meets display. PU gives a clean, lacquered look that flatters glass shutters and brass hardware. Common pairing with veneer back panels.
Bedroom furniture
Bedside tables, dressers, study units. Quieter places where PU's softness and lack of grain feels appropriate. Matte is the right choice here, almost always.
Vanity units
Bathroom-adjacent furniture takes constant moisture and steam. PU's water resistance beats laminate edges here — but use marine plywood underneath, not MDF.
Wall panelling
PU wall panels — especially in fluted or grooved profiles — are a trending alternative to wallpaper. Hard-wearing, easy to wipe, and uniform across an entire wall.
Ceiling panels
Decorative ceiling treatments — beams, coffers, drop panels — finished in PU for a clean architectural look. Best in living rooms and entry foyers.
Shoe & entry cabinets
High-touch, high-traffic. PU's scratch resistance pays off here. A common upgrade from laminate, especially in apartment foyers.
Where PU is usually the wrong choice
Skip PU on internal carcass boxes (no one sees them, laminate is cheaper), on rental property kitchens (the budget rarely justifies the cost), and on any unit you genuinely plan to replace inside 5 years. PU's value is in its longevity — pay for it only where you'll actually keep it.
Pros and cons
Every paid guide on PU lists ten advantages and never mentions a single drawback. Here is the version we actually tell clients.
What PU does well
- Seamless surface. No joints, no edge bands, no visible substrate. The shutter looks like a single piece of poured material.
- Colour freedom. Any RAL, any NCS, any custom mix. Laminates and acrylics cannot match this flexibility.
- Hard, scratch-resistant film once fully cured. Survives daily kitchen use better than enamel paint or melamine.
- Moisture and stain resistance. Wipe clean, no edge-swelling, no peeling at corners.
- UV stability in the modern formulations — premium brands no longer yellow noticeably in normal indoor light.
- Long life. A well-applied 2K PU finish holds up for 10–12 years before it starts to look tired.
- Premium hand-feel. A buffed matte PU surface has a softness laminate cannot replicate.
What PU doesn't tell you
- Two to four times the cost of premium laminate. Often more, depending on finish.
- Manufacturing time is longer — 5–7 days per unit minimum, against 2–3 for laminate.
- Repair is hard locally. A scratch or chip cannot be invisibly fixed at site; the panel usually has to go back to a spray booth.
- Skill-dependent. Two factories with the same materials produce visibly different results. The carpenter and sprayer matter as much as the brand of PU.
- Site PU is a downgrade. Done without a dust-free booth, the finish picks up particles and never looks factory-grade.
- Cheap PU exists and is widely sold. Single-component, brush-applied "PU" is technically PU but produces a finish closer to glossy enamel paint.
- Strong fumes during application — solvent PU is not something you want to be present for, especially with young children at home.
Compared with other interior finishes
This is the section most homeowners skip straight to, so we'll keep it dense and honest. Each row reflects how the finishes perform in a real Indian home — not in a brochure.
| Finish | Appearance | Cost / sqft | Durability | Repairable on site? | Best for |
|---|---|---|---|---|---|
| PU finish | Seamless, painted, any colour | ₹250–650 | 10–12 yrs | No | Premium kitchens, master wardrobes |
| Laminate | Printed pattern, visible edge band | ₹90–250 | 8–12 yrs | Partial | Mid-budget kitchens, rentals, kids' rooms |
| Acrylic | Glossy, glass-like, no grain | ₹350–600 | 10–12 yrs | No | High-gloss modern kitchens |
| Duco finish | Painted, less hard than PU | ₹180–400 | 6–8 yrs | Partial | Budget alternative to PU look |
| Membrane | PVC film thermo-pressed onto MDF | ₹150–280 | 5–7 yrs | No | Profiled shutters, classical designs |
| Veneer | Real wood grain, premium texture | ₹250–700 | 12–15 yrs | Yes — refinishable | Crockery, TV units, accent surfaces |
| Glass finish | Back-painted glass, very reflective | ₹350–550 | 15+ yrs | No | Statement units, splashbacks |
| PVC laminate | Cheaper, plasticky surface | ₹80–150 | 3–5 yrs | No | Budget rentals only |
| UV-cured finish | Factory-pressed, very smooth | ₹220–400 | 8–10 yrs | No | Pre-finished panels, slab shutters |
PU finish vs laminate — the most common comparison
Laminate is the default Indian kitchen surface for a reason: cost, choice and the fact that a damaged sheet can usually be swapped out without redoing the whole shutter. PU wins on appearance and feel; laminate wins on practicality and price.
Our honest recommendation: laminate for the lower cabinets and tall units that take daily damage, PU for the upper-band statement surfaces — island fronts, pantry doors, the wall you see when you walk in. This hybrid approach costs 30–40% less than full PU and looks nearly identical.
PU vs acrylic
Acrylic is essentially a sheet of high-gloss plastic bonded to the board. Closer to laminate in installation, closer to PU in look. The advantages: factory-controlled gloss, predictable colour, easier to clean. The disadvantages: you cannot get matte or super-matte in acrylic (it is intrinsically glossy), and edges still need banding. Choose acrylic if you specifically want mirror gloss; choose PU if you want anything else.
PU finish cost in India (2026)
Cost is where the PU market gets murky. Quotes can vary by 3x for what is nominally the same finish, and most of that variance is real — different brands, different application methods, different number of coats. Here is what each price tier actually buys you.
Budget PU (1K, brush)
₹180–250
Standard 2K spray PU
₹250–380
Premium 2K (ICA, Asian Paints)
₹380–500
Imported PU (Sirca, Milesi)
₹500–650
Metallic / textured PU
₹600–800+
Cost by application
- Modular kitchen (10–12 ft): ₹1.2 – 2.8 lakhs in PU alone, on top of the carcass cost. Mid-premium grade.
- Master wardrobe (8 ft × 7 ft): ₹65,000 – 1.4 lakhs depending on finish and brand.
- TV unit (10–12 ft wall): ₹55,000 – 1.2 lakhs for full PU; significantly less if you pair PU with veneer or back-painted glass.
- Whole apartment (3BHK, PU on all built-ins): Add ₹4 – 8 lakhs over a comparable laminate build.
What drives the price
Number of coats (premium jobs run 6–8 against budget's 3–4), brand of PU, sheen level (matte and mirror cost more than satin), colour complexity (custom RAL adds 10–15%), board material underneath, factory infrastructure, and carpenter skill. In that rough order of impact.
Factory PU vs site PU
If there is one decision in this guide we will be loud about, it is this one. Always insist on factory PU finish. Site-applied PU is sold at the same price, looks similar at handover, and falls apart faster than almost any other finish in your home. Here is why.
Recommended
Factory PU finish
- Dust-free spray booth — no particles trapped in the finish
- Climate-controlled temperature and humidity during curing
- Industrial spray guns deliver even, consistent coats
- Multiple coats with sanding between, properly cured
- Consistent finish across hundreds of square feet
- Honest warranties — usually 5–10 years on the finish
- Unit-by-unit quality inspection before dispatch
Avoid
Site PU finish
- Dust, mosquitoes, pet hair, hair from workers — all trapped in the wet finish
- No humidity or temperature control — finish cures unevenly
- Manual spray guns deliver inconsistent thickness
- Curing rushed to hand over the project on time
- Visible orange peel, runs, pin holes, dust nibs
- Warranties either absent or unenforceable
- Finish often shows defects within 6–12 months
The exception. Sometimes site PU is unavoidable — a built-in panelled wall that cannot be transported, a wide custom ceiling treatment, an in-place repair. In those cases, ask the vendor for: a sealed plastic tent over the work area, a HEPA-filtered air supply, and 72 hours of clear access after the final coat. It will still not match factory quality, but it can come close.
Best brands available in India
The brand of PU resin matters more than most homeowners realise. It affects film hardness, UV stability, colour depth, and how the finish looks five years in. Below is our honest take on the major brands available in 2026.
ICA
Italian · Premium
The benchmark for premium PU finishes in India. Best-in-class UV stability, deep colour saturation, excellent customer support. Slightly more expensive than Indian brands; usually worth it on signature projects.
Luxury tier
Sirca
Italian · Premium
Close competitor to ICA. Particularly strong on textured and metallic finishes. Widely specified by architects working on hospitality and high-end residential.
Luxury tier
Milesi (IVM Chemicals)
Italian · Premium · Wood-friendly
Particularly good if PU is being applied over veneer or solid wood — the resin chemistry preserves the substrate's character better than most. Niche but excellent.
Luxury tier
Asian Paints (Royale Touche, PU range)
Indian · Mass premium
The reliable choice for most projects. Good colour matching, solid technical support, wide availability. Slightly less depth of colour than Italian brands, but 30–40% cheaper.
Premium tier
Berger Paints (Woodkeeper PU)
Indian · Mid-premium
Strong on water-based PU range — a good pick for bedroom and kid's room furniture where VOC matters. Mid-range pricing.
Premium tier
Nippon Paint
Japanese-Indian · Mid-premium
Increasingly common in modular kitchen factories. Decent durability, reasonable price point, good warranty terms.
Standard tier
On different boards
The board underneath your PU finish matters far more than people realise. PU is only as stable as the board it's bonded to — a warped substrate will pull the finish with it, no matter how good the spray job was.
MDF — the standard for PU
Medium Density Fibreboard is the most common substrate for PU finish, and for good reason: its dense, uniform surface holds primer and PU coats beautifully, with no grain to telegraph through. The downside is moisture sensitivity — standard MDF swells when exposed to water. For kitchens and vanities, demand boilo-MDF or HDHMR (see below) instead.
HDHMR — the upgrade pick
High-Density High-Moisture-Resistant board. Denser than MDF, holds screws better, resists moisture far longer. Costs roughly 25–35% more than MDF but is the right call for kitchens, vanities and any humid area. If your vendor quotes PU on MDF for a kitchen, ask about HDHMR — the upgrade is usually worth it.
Plywood — the durable choice
BWP-grade plywood gives the best long-term durability, especially in moisture-prone areas. The trade-off: ply has a visible grain that needs heavy priming and sanding to suppress, otherwise it telegraphs through the PU coat. More expensive in finish prep, but mechanically the strongest base.
Veneer with PU top coat
A specific combination worth its own mention: real wood veneer pasted onto plywood, then sealed with a clear PU top coat. You get the grain of real wood with the durability of PU. This is what high-end crockery units, library walls and library-style TV units are usually built from. Premium pricing, lasting result.
Solid wood with PU
Rare in modular contexts (too expensive, too dimensionally unstable for large shutters), but used for accent furniture — dining tables, statement chairs. PU over solid wood gives a hard protective shell while preserving the wood's grain if a clear top coat is used.
How durable it is, and how to care for it
A well-applied 2K factory PU finish should last 10–12 years before showing its age. Some of that depends on the spray; most of it depends on how you treat it.
What PU resists, and how well
- Scratches: resists everyday wear well, but a determined ceramic plate edge or a metal vessel base will leave a mark. Matte hides minor scratches; gloss reveals them.
- Water: excellent. Standing water for hours does no damage to the film, though edges are only as good as the sealing underneath.
- Heat: moderate. Don't place hot vessels directly on PU shutters or counters — anything above 80°C can blister the finish.
- UV: modern formulations resist yellowing well. Older formulations and cheap PU still yellow visibly in 3–4 years, especially in white finishes near windows.
- Chemicals: mild kitchen cleaners are fine. Acetone, paint thinner, undiluted bleach will damage the surface.
Daily and weekly care
Wipe down with a soft, lint-free microfibre cloth and a few drops of mild dish soap in lukewarm water. Avoid abrasive sponges, steel wool, and any cleaner labelled "scouring" or "heavy duty." For weekly maintenance, use a dedicated furniture polish designed for painted surfaces — not wood polish, which can leave a sticky residue on PU.
Common problems to watch for
- Orange peel: a bumpy texture from incorrect spray viscosity. Should never appear on a factory finish; if it does, ask for re-finish under warranty.
- Pin holes / bubbles: caused by trapped air or moisture in the primer. Visible only at the right angle of light; usually appears in the first month.
- Yellowing: mostly a problem with cheap or older PU formulations in white finishes. Premium 2K PU should not yellow noticeably in 5–7 years.
- Cracking at corners: usually a substrate problem (board movement), not a PU problem. The fix is at the board level.
- Uneven gloss: happens when the final buff was rushed. Visible as patches of different sheen on the same panel.
Quality checklist before you accept delivery
1. Uniform colour across all units. View the units side by side under the same light. Different batches should be indistinguishable.
2. Smooth, dead-flat surface. Run your palm across the panel. You should feel no texture, no nibs, no orange peel.
3. Crisp, fully wrapped edges. The edge should be the same colour and finish as the face, with no visible substrate or paint break.
4. Reflection test. For gloss and satin finishes, look at a window's reflection in the shutter. The reflection should be sharp and undistorted.
5. Touch test for hardness. Press a fingernail into a hidden area. A properly cured PU finish will not dent or mark.
6. No visible joints inside the unit. Open the shutter and check the inside edges — joinery should be clean, with no PU drips into the interior.
7. Door alignment. All shutters should align flush with each other when closed. Misalignment is a carpentry issue, but it shows up worse on PU than on laminate.
Mistakes homeowners make
- Picking PU because it sounds premium. Without understanding 1K vs 2K, factory vs site, or which brand, you are buying a category, not a finish. Read the quote, ask the questions.
- Allowing site PU because the vendor says it's fine. It is not fine. Insist on factory finish, even if it adds two weeks to delivery.
- Choosing high gloss for a daily-cook kitchen. The first week is glorious. By month three you'll be wiping fingerprints every evening.
- Skipping the curing period. Accepting delivery before the 7-day cure means living with a fragile finish for the first month. Push back on rushed timelines.
- Cheap MDF underneath premium PU. The board is half the durability story. A premium PU finish on cheap MDF will fail at the edges and joinery within two years.
- Approving the finish from a photo or showroom sample. Always insist on a 6"×6" sprayed sample on the actual board, in the actual colour, viewed in your home's lighting.
- Not asking about warranty. A reputable factory will offer a 5–10 year warranty on the finish itself, separate from the carpentry. If the vendor refuses, that tells you what they think of their own work.
Is PU finish worth the money?
The honest answer depends on which home this is. Here is how we advise our own clients.
If you're building a budget home (under ₹15 lakh total interior cost)
Skip full PU. Use it selectively — one statement unit, maybe the island front and the pantry doors — and use premium laminate everywhere else. You'll get 80% of the visual impact for 40% of the cost.
If you're building a mid-premium home (₹15–35 lakh interior cost)
The sweet spot for PU. Use it on the kitchen shutters that you see when you walk in, on master wardrobe shutters, and on the main TV unit. Laminate the rest. This is where PU pays for itself in daily feel and aesthetic value.
If you're building a luxury home (₹35 lakh+ interior cost)
Full PU is reasonable, but consider mixing it with veneer or back-painted glass on accent surfaces. A house where every shutter is the same PU finish reads strangely uniform; mixing materials gives the interiors layered depth.
If this is a rental property or a 5-year flip
Don't do PU. The cost will not be recovered in rent or resale. Premium laminate looks similar enough in photographs, and the maintenance is easier for tenants.
Our default recommendation
For an owner-occupied home you plan to live in for ten years or more, factory 2K PU finish from a premium brand (ICA, Sirca, Milesi, or Asian Paints' top range) on the surfaces you touch and see daily — kitchen, master wardrobe, TV unit. Laminate or membrane on internal carcasses and lower-traffic units. Spend deliberately, not uniformly.
Frequently asked questions
Is PU finish better than laminate?
Better for appearance and feel — PU gives a seamless, painted look that laminate cannot match. Worse for budget, repair-ability and lead time. Laminate is the practical choice for daily-use surfaces; PU is the right choice when the look matters more than the maths. Most well-designed Indian homes mix both.
Does PU finish scratch easily?
No, when it is properly cured 2K PU. Light scratches are uncommon and deeper marks need real force — a cooker base scraped across the shutter, a steel vessel edge. The catch is that any scratch is harder to hide than on laminate, because PU is a solid colour without printed grain to break it up.
Can PU finish be repaired?
Not invisibly at site. A skilled spray technician can patch a damaged shutter, but the patch will be visible unless the entire shutter is re-sprayed — which means the unit has to go back to a factory booth. Plan for this when you commit to PU: it is more expensive to repair than to install.
Is PU finish waterproof?
Water-resistant, not waterproof. The PU film itself shrugs off water indefinitely. The weak points are the edges and the substrate underneath. If water gets into a seam or a screw hole over months, the board can swell and the finish will lift. Wipe up spills, don't let standing water sit, and you'll be fine.
Does PU finish turn yellow over time?
Modern 2K PU from premium brands resists yellowing well — you should not see noticeable colour shift for 7–10 years. Cheap PU formulations, single-component PU, and PU exposed to constant direct sunlight can yellow visibly within 3–4 years, especially in white finishes. Brand matters here more than anywhere else.
Which PU finish lasts the longest?
Matte and satin finishes in 2K formulations from premium Italian brands, applied in a factory booth on HDHMR or BWP plywood. Realistic lifespan: 10–12 years before refinishing. Mirror gloss tends to micro-scratch and look dull sooner — 6–8 years in heavy-use areas.
Is PU finish safe for kitchens?
Yes — once cured. The fumes during application are significant, which is why PU should always be sprayed in a factory and given the full 7-day cure before being installed in your home. Once cured, the finish is food-safe, heat-tolerant (within reason), and easy to keep clean.
Is PU finish safe for children's rooms?
Yes, with one caveat: choose water-based PU rather than solvent-based for kids' room furniture. Water-based PU has dramatically lower VOC content, milder smell during the first few weeks, and an indistinguishable finish to most eyes. Brands like Berger and Asian Paints both have water-based ranges worth specifying here.
Can PU be re-polished after years of use?
Yes — but it is a project. The shutters need to be removed, taken back to a factory booth, sanded down to the primer coat, and re-sprayed. Expect to pay roughly 50–60% of the original PU cost for a refinish. Cheaper than replacing the cabinetry, more expensive than re-laminating.
How many coats of PU are required?
A serious PU job uses 6–8 coats: 2 primer coats, 2–3 base colour coats, 1–2 top coats, with sanding between each. Budget jobs cut this to 3–4 coats and you can see the difference in the final surface. Always ask your vendor how many coats are in the quote — vague answers usually mean fewer coats.
What is the drying and curing time?
Surface dry within 4–6 hours of the final coat — light enough to touch carefully. Handling dry within 24 hours. Full chemical cure takes 5–7 days, after which the film has reached its maximum hardness. Units should not leave the factory before the full cure completes, and they should not be subjected to heavy daily use for another 7–10 days after installation.
Which is more expensive: acrylic or PU?
They overlap significantly. Mid-tier acrylic is usually similar in price to standard 2K PU (₹350–500/sqft). Premium imported PU from ICA or Sirca costs more than top-tier acrylic. The deciding factor is finish: if you specifically want mirror gloss, acrylic is usually the better value. For matte, satin, or custom colours, PU is the more flexible choice.
Which finish gives the best luxury look?
For sheer "this feels expensive" appeal, matte PU in a deep custom colour (forest green, navy, oxblood) on a tall pantry unit or kitchen island is hard to beat. Mirror-gloss acrylic and back-painted glass are equally striking in different ways. None of these will save money — they are aesthetic choices, not budget ones.
