You’ve invested in beautiful wood for your house – furniture, floors, walls or elsewhere. To get the best out of it, wood needs some sort of clear wood finish. It brings out a richer hue, highlights the grain and gives lustre. These finishes are protective coatings as well, which add durability and provide protection to the wood from spills and scratches that are caused by daily usage. It is essential to select the right finish for the wooden flooring and furniture of your home. One can classify the protective coatings into three categories: lacquers, varnishes and polyurethane. These three impart different kinds and degrees of protection, and come with different characteristics.
Here are the strengths and shortcomings of these three popular wood finishes. Take your pick.
Here are the strengths and shortcomings of these three popular wood finishes. Take your pick.
Lacquer finish
Lacquer finish is a clear protective coating that imparts richness and can bring out the natural beauty of wood grains. Some lacquer finishes may contain colour pigments that can darken the colour of wood.
Pros:
Lacquer finish is a clear protective coating that imparts richness and can bring out the natural beauty of wood grains. Some lacquer finishes may contain colour pigments that can darken the colour of wood.
Pros:
- Lacquer finish is a very quick-drying wood finish.
- It creates a hard protective coating that makes wood resistant to damage from elements like water, acid or alkalis.
- A single coat of lacquer is enough to protect the wood furniture from stains and damage caused by water.
- The finish is available in various sheens, ranging from high-gloss to ultra-matte.
Cons:
- One of the biggest drawbacks is that lacquers get a yellowish tinge over time.
- Lacquered floors and surfaces are prone to scratches because only a single layer of coating is sprayed on the wooden surface.
- This coating can only be applied on new surfaces of wood or on previously lacquered wood. Keep in mind that if lacquer is applied on a previously painted or polished surface, it might react with the old finish and strip it from the base wood surface.
- Lacquers emit VOCs (volatile organic compounds) that can be a health hazard. It is highly inflammable.
Varnish finish
Varnish is an oil-based protective coating for wood that enhances its natural beauty.
Pros:
Varnish is an oil-based protective coating for wood that enhances its natural beauty.
Pros:
- Varnishes provide good protection to wooden furniture against damage from UV rays. This makes varnish finishes most suitable for finishing outdoor wooden furniture.
- These coatings protect the wooden surfaces from water, stains and abrasion.
- Varnishes are easy to apply and only require a bristle brush for application. Make sure to use varnish in a dust-free environment, otherwise dust particles might stick onto the wet varnish surface.
Cons:
- It is a very slow-drying finish because of the oil content present in it and may require a minimum drying time of 6 hours.
- Varnish finish emits VOCs.
- One must ensure proper application of varnish, or there are chances the varnish might peel, crack or form bubbles, and cause damage to the wooden surface.
- The varnish finish on wood may require several coats to achieve the desired finish.
Polyurethane finish
Polyurethane finish is very hard and durable that forms a solid layer of plastic on the wooden surface. These coatings can be either oil-based or water-based. Note that water-based polyurethane dries faster than oil-based polyurethane.
Pros:
Polyurethane finish is very hard and durable that forms a solid layer of plastic on the wooden surface. These coatings can be either oil-based or water-based. Note that water-based polyurethane dries faster than oil-based polyurethane.
Pros:
- Polyurethane is a strong finish and forms a very tough coat that provides excellent protection to the wood against spills, scratches and abrasions from traffic.
- It is highly recommended for the wooden floors that are subjected to the most wear and tear.
- Additionally polyurethane finish on wood works very well on furniture in coastal areas that are constantly exposed to salt-laden air.
- Polyurethane varnish provides a very tough seal in comparison to standard varnishes or lacquers.
Cons:

@zainali very useful insight-thanks
Hi Pooja and zainali,
I made a new wall to wall bookshelf. The dimension is 6 feet tall, 8 feet wide and 11 inch deep. The bookcase has glass door (yet to attached). The carpenter used raw wood that has moisture. After he fixed it to wall, I tried to put my books on sheves, but the books became oggy and dump. How to prevent the dumpness on wooden shelves/planks so I can start to usethe bookshelf? is polyutharine finish seal the moisture of shelves?
@ Rashmi... Most finishes are water resistant. If it is a loose bookshelf...expose it to proper sunlight so that it can completely dry before applying any finish
