Wood Finishes
Types of Wood Finish
If you are looking at finishes for a wooden door, wardrobe or piece of furniture, you have probably come across names like PU, melamine, lacquer and varnish. They can all sound similar when you are seeing them on a quotation, but they do quite different jobs.
The easiest way to choose is to first decide what you want from the wood. Do you want to keep the natural grain visible? Do you want a solid colour? Does the surface need to handle a lot of use? Once you know that, the finish becomes much easier to choose.

Finishes and Coatings for Wood Sheet Materials
Wood does not stay looking new just because it is good-quality wood. Daily use, dust, cleaning, moisture and sunlight can all affect the surface. A suitable finish gives the wood a layer of protection and also decides much of its final appearance.
Take a dining table as an example. It gets wiped, touched, and exposed to food and drinks almost every day. A wardrobe has a different kind of use, while a main door may have to deal with dust, fingerprints and changing weather conditions.
The finish needs to suit that use. Some finishes are chosen mainly for durability, others for their appearance, and some give you a good balance of both.
A properly finished surface is easier to maintain and less exposed to everyday wear. It can help protect against small scratches, stains and moisture, although no coating will make wood completely damage-proof.
Preparation matters just as much. Sanding, filling and sealing the surface properly before applying the finish can make a noticeable difference to how long it lasts.
These three terms are often mixed up, so it is worth getting this part clear before looking at specific finishes.
Option | What it does | Natural grain visible? | Common uses |
Wood paint | Adds a solid colour and covers the surface | Usually no | Doors, furniture, panels |
Changes the colour of the wood | Yes | Furniture, doors | |
Protects and seals the surface | Usually yes | Furniture, doors, woodwork |
Wood paint is mainly about colour. If you want a white, grey, green or any other solid shade on a wooden surface, paint will cover most of the natural grain.
This can be useful for older furniture or doors that need a completely different look. It is also a practical option when you want the woodwork to match the rest of the room.
Stain is different because it works with the natural appearance of the wood. It changes or deepens the colour while allowing the grain to show.
If you have a good-quality wooden door or furniture piece and like its natural character, staining can give it a richer appearance without covering it up.
A wood finish is the protective layer that goes over the prepared surface. Clear finishes can protect the wood while leaving its colour and grain visible.
PU, melamine, lacquer and wood varnish are some of the finishes you will commonly come across. The right one depends on the type of wood, the use of the furniture and the finish you want.
There is no single finish that works best for every piece of wood. The four options below are among the ones you are most likely to come across for interior woodwork.
PU is often chosen for furniture and doors where the surface needs to handle regular use. It forms a protective layer over the wood and can be available in different levels of sheen.
It is worth considering for dining tables, work desks, cabinets and frequently used doors. If you are spending money on good timber, a durable PU finish can help protect that investment.
Melamine is commonly used for indoor furniture and woodwork. It gives a clean finished surface and is often selected for wardrobes, cabinets and similar applications.
Melamine Finish can be a practical choice when you want reasonable durability without moving into a more expensive finishing system. For several pieces of interior furniture, the cost difference can also become important.
Lacquer is popular when a smooth appearance is a priority. It generally dries relatively quickly and can give furniture a neat, refined finish.
It can be used in different sheen levels, depending on the product and the look you want. It is often seen on furniture where the finish itself is an important part of the design.
If you want to keep the natural look of the timber, a clear coat or wood varnish is worth considering. Instead of changing the wood into a completely different colour, it protects what is already there.
This can work particularly well on good-quality wood with an attractive grain. You get protection without losing the character that made you choose the wood in the first place.
Once you know what each finish does, the choice usually comes down to three things: how much use the surface gets, how you want it to look and what you want to spend.
PU is generally the stronger choice when resistance to everyday wear is important. Melamine works well for many interior furniture applications, while lacquer is often chosen more for its appearance and application properties.
Keep in mind that the coating is only part of the equation. Poor sanding, dust on the surface or applying coats incorrectly can affect the result even when you have bought a good product.
For a wardrobe or standard cabinet, melamine can be a sensible option. For a dining table, desk or frequently used door, you may prefer the added protection of PU.
Lacquer can suit furniture where you want a smooth, clean finish. If you are finishing expensive furniture or several pieces at once, a professional wood-finishing service can be useful. They can assess the existing surface and recommend the complete preparation and coating system.
There is no fixed price difference because the total cost depends on the surface, preparation, number of coats and application method as well as the finish itself.
Melamine is often used for more budget-conscious furniture work. PU can cost more, particularly when professional application is involved, but it may make sense for furniture that needs greater protection. Lacquer prices vary depending on the product and the finish required.
When comparing quotes, check whether sanding, filling, primer or sealer and application are included. A cheaper coating is not necessarily the cheaper job if the preparation has been left out.
The choice here is fairly straightforward once you know what you want the furniture to look like.
Lacquer can give furniture a smooth, finished appearance and generally has a relatively quick drying time. It is useful when you want a clean decorative finish and do not want a long gap between coats.
A clear coat makes more sense when the wood itself is worth showing. It leaves the grain visible while adding a protective layer over it.
For a good wooden table, cabinet or door, this can give you a much more natural result than covering the surface with paint.
For furniture that is used heavily, protection should be one of your first considerations. A dining table or work desk needs to cope with regular contact, cleaning and occasional spills.
A durable clear coat or PU system may be more suitable in such cases. If you are unsure, ask the finishing professional what the product is designed to withstand rather than choosing based only on the level of shine.
Plywood and MDF are now used in a large part of interior furniture. Wardrobes, kitchen cabinets, TV units and storage furniture are often made from these materials rather than solid wood.
That changes the preparation slightly, especially around the edges.
The surface should be smooth before the final coating goes on. Dents and uneven areas need to be filled, while exposed edges may need additional preparation because they can absorb the coating differently from the main surface.
A suitable primer or sealer can help create a more even base. If you are having furniture made by a carpenter, ask what preparation will be done before the final finish is applied.
Kitchens are an obvious example where moisture needs attention. Water and humidity can cause problems for wood-based sheets if the material is not properly protected.
A moisture-resistant coating can help, but it should not be the only line of protection. Edges, joints and areas around sinks should also be properly sealed.
Kitchen panels need to be easy to wipe and able to handle regular cleaning. For wardrobes, you have more flexibility, so the decision can come down to appearance, durability and budget.
If the furniture is being made specifically for your home, discuss the finish before the work starts. Changing the finish later can mean additional sanding and preparation.
If you want a wooden door to have a solid colour rather than a natural wood appearance, you will probably be looking at paint rather than a clear finish.
Enamel paint for wood is commonly used on doors, trims and furniture. It can create a hard, smooth surface that is relatively easy to clean.
It is particularly useful when you want the woodwork to have a specific colour and do not need the natural grain to remain visible.
Oil paint has been used on woodwork for a long time and is known for its durable finish. The downside is that it can take longer to dry and may have a stronger odour during application.
If you are using it indoors, proper ventilation is important. Always follow the product instructions for drying and recoat times.
For a door that needs a solid colour, enamel can be a practical choice. If the door has attractive natural timber, however, painting may hide one of its best features.
In that situation, a stain followed by a clear protective coating can give you colour and protection while still allowing the grain to show.
A good finish starts with the surface underneath. If the wood is rough, dusty or uneven, the final coating will not hide those problems as well as you might expect.
Remove dust, grease and any loose old coating. Check the wood carefully for cracks, dents, holes or damaged areas.
Sand the surface evenly until it feels smooth. Take your time around corners and edges, where rough patches are easy to miss. Remove all sanding dust before continuing.
Use a suitable wood filler for holes and dents. Once it has dried, sand the repaired areas so they sit level with the rest of the surface.
The need for primer or sealer depends on the material and the finish you are using. MDF edges and some plywood surfaces may need particular attention.
If you are not sure which product to use, check that the primer or sealer is compatible with the topcoat. Paint stores and professional painting services can also help you choose the right combination.
Apply the finish in even coats and avoid trying to get full coverage by putting on one very thick coat. Follow the manufacturer's instructions for application and recoat time.
Do not rush between coats. Temperature, humidity and ventilation can all affect drying time, so give the coating enough time to dry properly before continuing.
Once the final coat has dried, inspect the surface in good light. Look for rough spots, uneven coverage or small particles caught in the finish.
For one or two small pieces, this can be a manageable DIY job. For a full set of doors, built-in wardrobes or expensive furniture, professional wood-finishing services can save a lot of time and help achieve a more even result.
Wood paint gives the wood a solid new colour and usually covers the grain. Wood stain changes the colour while keeping the grain visible. A wood finish protects the surface and can be clear or slightly tinted depending on the product.
Think about use first. PU is a good option for surfaces that need stronger protection, melamine is commonly used for practical indoor furniture, and lacquer is often chosen when a smooth decorative finish is the priority.
Lacquer can give furniture a smooth appearance and generally dries relatively quickly. Clear coats are better when you want to keep the natural wood visible while protecting it. For attractive timber, a clear coat can be the more suitable choice.
Plywood and MDF can be finished with PU, melamine, lacquer, varnish or paint. The right option depends on where the panel is being used, how much wear it will receive and whether you want a painted or natural-looking surface.
Both can be used when you want a painted wooden door. Enamel is commonly chosen for a smooth, hard and easy-to-clean surface, while oil paint is a traditional option that can take longer to dry and may have a stronger odour. If you want to keep the natural grain visible, a stain and clear finish would be a better direction.
