Wood Furniture Finishes Explained: PU, Melamine, Lacquer, Wax, and Oil — Which One for Which Piece

A wood finish does three things: it protects the wood from water, dirt, and wear; it makes the surface look the way you want; and it ages over time in characteristic ways.

In Indian furniture retail, you'll hear five terms used almost interchangeably and almost always wrongly: PU, melamine, lacquer, wax, and oil. They're five completely different finishing systems with different applications, durability, costs, and repairability. Knowing the difference changes what you ask for at the showroom — and what you say yes to.

This is the long version.

Why the finish matters more than people think

The finish is the layer between you and the wood. It absorbs:

• Water spills (from glasses, plants, monsoon humidity)
• UV light (fades colour over years)
• Physical abrasion (sliding objects, kids' toys, your sleeve)
• Chemical contact (cleaners, sanitizer, oil, ink)

A great wood underneath a bad finish looks bad and ages worse. A modest wood underneath an excellent finish can last decades looking handsome.

The five finish families

1. Wax (paste wax, beeswax)

The oldest finish and still one of the best for solid wood that gets gentle care.

• What it is: a paste of beeswax + carnauba + a thin oil base
• How it goes on: rubbed in by hand with a cloth, allowed to dry, buffed off
• Build: very thin — wax sits in the pores of the wood, not on top
• Look: soft satin sheen; emphasises the grain
• Touch: silky, warm
• Water resistance: poor — water spots if not wiped off in minutes
• Heat resistance: moderate — hot cups will leave a mark
• Scratch resistance: poor; scratches are easy to make and easy to fix
• Repairability: excellent — re-wax the affected area, done in 10 minutes
• Lifespan before re-coat: 12-18 months for daily-use pieces
• Best for: bookshelves, side tables, headboards, decorative cabinets — anything that doesn't get water or hot things on it
• Worst for: dining tables, coffee tables, kitchen surfaces

2. Oil (linseed, tung, Danish oil)

Oils penetrate into the wood rather than sitting on top. They're the most "natural" looking finish.

• What it is: a drying oil (linseed, tung) or oil/varnish blend
• How it goes on: rubbed in with a cloth, excess wiped off, allowed to cure
• Build: very thin — like wax, it's in the wood
• Look: very low sheen; the wood looks almost unfinished but is protected internally
• Touch: dry, slightly silky
• Water resistance: moderate (better than wax, worse than film finishes)
• Heat resistance: moderate
• Scratch resistance: moderate; scratches blend in easily because there's no film to break through
• Repairability: excellent — sand lightly, re-oil
• Lifespan before re-coat: 18-36 months
• Best for: dining tables (some applications), butcher blocks, kitchen surfaces, outdoor teak furniture
• Worst for: anything you want a glossy showroom finish on

Note: linseed oil from a paint store is not the same as a furniture oil. Boiled linseed oil (BLO) is treated to cure faster. Raw linseed oil takes weeks to cure and stays sticky. Use the right product.

3. Lacquer (nitrocellulose, NC lacquer)

The traditional Indian factory finish before PU took over in the 2010s.

• What it is: a fast-drying solvent-based film finish
• How it goes on: sprayed in multiple thin coats; each dries in minutes
• Build: thin to medium film
• Look: glossy, sometimes very glossy; can be flatted to a satin
• Touch: hard, smooth
• Water resistance: moderate
• Heat resistance: poor — hot cups cause white marks
• Scratch resistance: moderate
• Repairability: moderate — new lacquer melts into old lacquer when applied, which means damage can be repaired without a full strip
• Lifespan before re-coat: 8-15 years (degrades by yellowing over time)
• Best for: factory furniture, decorative pieces
• Worst for: outdoor use, dining tables with hot dishes

Lacquer has been steadily replaced by PU in Indian factories because PU is more durable. But lacquer remains an excellent finish if applied well.

4. Polyurethane (PU)

The dominant Indian factory finish in 2026, and for good reason.

• What it is: a 2-part chemical finish that cures by chemical reaction (not just evaporation) into a hard plastic-like film
• How it goes on: spray-applied, 2-4 coats, each cures over hours
• Build: thick film
• Look: range from satin to high-gloss, depending on additive
• Touch: very hard, plastic-like
• Water resistance: excellent
• Heat resistance: good (better than lacquer; still not heat-proof)
• Scratch resistance: excellent
• Repairability: poor — damage requires full sand-back to bare wood
• Lifespan before re-coat: 12-20+ years (very durable, but when it fails it fails dramatically)
• Best for: dining tables, kitchen tables, kids' furniture, kitchen cabinets, MDF panels, painted finishes
• Worst for: pieces where you want a natural wood feel

PU is the right answer for most modern furniture in Indian conditions where a hard durable surface matters more than a soft natural feel.

5. Melamine

Not actually a wood finish in the traditional sense — melamine is a laminate sheet glued onto a substrate.

• What it is: a paper-thin layer of resin-impregnated decorative paper, fused under heat and pressure
• How it goes on: glued onto the MDF/particle board panel at the factory
• Build: the laminate itself is a separate material; there is no finish "in" the wood because there's no wood
• Look: can be printed to mimic any wood grain, marble, plain colours
• Touch: smooth, slightly plastic
• Water resistance: excellent on the surface; the edges (where the laminate is glued) are vulnerable
• Heat resistance: moderate
• Scratch resistance: moderate — scratches go through to the substrate
• Repairability: zero — once scratched, the only fix is replacement
• Lifespan: 8-15 years; failure mode is edge peeling, not surface wear
• Best for: kitchen cabinets, wardrobe carcasses, low-cost furniture
• Worst for: anything you want to age into character

Melamine is the right answer for kitchens and wardrobe interiors. It's an okay answer for budget furniture. It is the wrong answer for dining tables, beds, or anything you'd like to refinish in 15 years.

What we use at bare nest

A piece-by-piece breakdown of how we finish furniture in the workshop:

• Beds (rails, posts, headboard frame): PU satin — durable, easy to wipe, looks contemporary
• Bed headboard panels: PU satin or matte (chosen by customer)
• Wardrobe doors (solid wood): PU satin
• Wardrobe carcass (MDF): white melamine on internal panels
• Dining tables: PU matte for daily-use tables; oil + wax for customers wanting a natural look (they accept the maintenance trade-off in writing)
• Coffee tables, side tables: wax or PU depending on customer
• Shelving units: wax (lower wear, easier to refinish)
• Office desks: PU matte
• Custom pieces: any of the above, customer's choice

Choosing the right finish for your home

The questions to ask yourself:

1. Will hot things sit on this surface? If yes, lean PU.
2. Will water spill on this surface? If yes, PU or oil.
3. Will it scratch? (Kids, pets, daily wear.) If yes, PU.
4. Do I want a "natural wood" feel? If yes, oil or wax — accept the trade-off.
5. Will I want to refinish in 15 years? If yes, wax or oil. (PU can be refinished but requires sand-to-bare-wood.)
6. Indoor or outdoor? Outdoor = oil (specifically marine oil) or marine-grade exterior PU. Never melamine outdoors.

Finish maintenance, by type

Wax-finished pieces

• Dust weekly with a dry cloth
• Re-wax every 12-18 months (20-minute job per piece)
• Buff between coats for shine
• Avoid water spills; wipe immediately if they happen

Oil-finished pieces

• Dust weekly
• Re-oil every 1-3 years depending on wear
• Don't use water-based cleaners
• Dining tables: re-oil more frequently

Lacquer-finished pieces

• Dust weekly
• No special maintenance for 10+ years
• Yellowing in years 8-12 is natural; refinish or live with it
• White cup marks come out with a soft cloth and a tiny amount of toothpaste (no joke — it polishes out)

PU-finished pieces

• Dust weekly
• Clean with a damp cloth and mild soap, no harsh chemicals
• No re-coating needed for 15-20 years
• When damaged, requires professional refinish

Melamine-finished pieces

• Wipe with damp cloth
• Clean spills immediately
• Avoid abrasive cleaners
• Cannot be refinished; replacement is the only repair

The myth of "polish"

"Polish" in Indian colloquial use is a generic term that covers anything from wax to PU. When a salesperson says "this is polished sheesham", ask "what finish?" — they should know if they're worth buying from.

Specifically beware of:

• "Hand polish" — usually a French polish or shellac, beautiful but fragile, almost no longer applied in modern factories
• "PU finish" sold as if it's the only premium option — it is one premium option; not always the right one
• "Italian finish" — meaningless marketing
• "Imported polish" — meaningless marketing
• "7-coat PU" — number of coats matters less than skill of application; 3 coats well-applied is better than 7 coats poorly

Pricing for finishes (per square foot, added to base furniture cost)

Finish	Cost added per sqft (₹)
Wax	80-150
Oil	120-200
Lacquer	250-400
PU satin	350-550
PU matte	400-600
PU high gloss	600-900 (more difficult; more rejects)
Melamine	(built into the panel cost)

For a 60"×36" dining table, the difference between wax and PU is about ₹3,500-₹5,000. That's the cost of the finish decision in absolute terms — small relative to the total piece cost, but it changes how the piece behaves for decades.

The honest summary

If you ask me what finish to put on a piece of furniture, my answer depends on what the piece is for. There is no universally best finish — there are good answers for each use case.

The two most common mistakes:

1. Asking for wax on a dining table because it looks "premium" — then complaining about water spots after the first dinner party.
2. Asking for high-gloss PU on a bedroom dresser — then realising every fingerprint shows.

Match the finish to the use. Ask explicitly when buying. Insist on a finish sample on actual wood before signing off on custom pieces.

If you're choosing between options for a piece we're making, we'll walk you through both at the studio — bring your phone, we'll show you finished examples in both treatments and let you decide.
