Four of the most popular are polyurethane, lacquer, varnish, and epoxy. Application techniques vary depending on the product, but we'll give you a general idea of how to apply your finish. Clean the wood completely before applying the finish. If the wood is already finished, sand it off before applying a new one.
Polycrylic topcoats are my sealer of choice for most projects, as they don't tend to yellow as often as polyurethane. Clear furniture wax can also be used to seal natural wood projects. Furniture wax provides a soft, silky finish to a piece, which can be lovely.
Sealers Vs Primers
The best rule to adhere to is to apply at least two coats of sealer directly onto the raw wood. This will protect the wood and create a barrier. Then apply primer to enhance adhesion, return tooth to the surface, and whiten the surface for optimising paint colours you plan to apply over it.
Paint Or Seal Unfinished Furniture
Bare wood, when left unfinished, keeps your furniture with a natural wood look but the risk is exposing it to harsh elements, even if it's indoors, such as light, dust, moisture and water damage, making it more susceptible to stains, warping and cracking.
To seal wood properly first prepare the surface by sanding it smooth and, if you like, staining it a color. Then you can apply a sealant, but there are many to choose from. The three most common sealants are polyurethane, shellac, and lacquer, and each requires a different method of application.

PermaSeal® will restore and keep your deck protected for 25 years after just ONE treatment.
What's the Different Between a Sealer and a Waterproofer? Sealers and waterproofers perform similar functions, but they differ slightly in how they work. A wood or concrete sealer will protect the surface. Waterproofers are more durable than sealants because they penetrate the surface, filling in leaks or gaps.
Polyurethane Wood Finish
Polyurethane wood finishes are synthetic coatings that are highly durable and water resistant, making them the best clear coat for wood protection.
And the answer is yes. Sometimes. Wood can be left unfinished if it won't encounter weather, water or significant handling. If your project is placed outside, will be somewhere wet, or will be used on a regular basis, then you should apply wood finish.
What is this? As a whole, untreated wood can be used outside. Proactive steps should be taken to make untreated wood a viable option for long lasting projects when used outdoors. Steps such as sealing, painting or using other bonding agents to increase the life of untreated wood.
Yes! A polyurethane wood finish looks beautiful and is one of the most durable top coats for wood finishes. It works great on stained wood, raw wood, weathered wood finishes, and painted wood finishes too.
Once the second coat has dried, sand or shave off any imperfections as you did in step 4. With many oil-based polyurethanes, two coats will be enough. If you're happy with how the job looks, wait a few days, then finish by polishing the surface with a polishing compound.
Oil-based primers are ideal for interior and exterior unfinished or bare wood because they seal the porous surface of wood, enabling the coat of paint to better cover the surface. They stop tannins, released from woods, such as cedar or redwood, from bleeding through the surface of the paint.
What happens if you don't prime bare wood is not pretty. Similar to new drywall, raw wood soaks up paint like a sponge. As a result, your surface will look blotchy since pores in the woodwork unevenly absorb the paint. More importantly, the painted wood will likely peel in two or three years without primer.
The product I'd recommend for light duty sealing of raw wood pieces is Miss Mustard Seed's Hemp Oil. One of the things I really like about it is that it does a good job of preserving the beautiful patina on my more vintage (or vintage look) pieces.
Untreated wood can last anywhere from a few months to several years, depending on different factors such as the type of wood, the climate, and the level of exposure to the elements. For example, cedar and redwood are naturally resistant to decay and can last up to 20 years or more.
It depends on the climate, the type of wood, its uses, and how well it's maintained. While pressure treated poles can stay up to 40 years without any signs of rot or decay, decks and flooring might only last around 10 years.
Do I need to apply a clear waterproofer over my stain? Not with Thompson's® WaterSeal® Wood Sealers. They are specially formulated so you get unsurpassed waterproofing protection and beautiful color at the same time.
An epoxy sealer with an exterior varnish topcoat is the most durable outdoor finish and can last for many, many years. However, the initial application does take longer than exterior varnish.
