Varnish is great option to treat untreated wood for outdoor use because it's relatively cheap and provides superior protection for your wood. It can also last longer than some other sealants, which is something we all want.
There are three types of clear topcoats used to seal natural wood or bleached furniture – polyurethane, polycrylic, and wax finishes.
Untreated wood is the most susceptible to rot, fungi, and general weathering. It's extremely important that you use a wood preservative first. You can either use a wax enriched preservative for an all-round coating or alternatively use a wax-free preserver if you want to then use a stain or a paint on top.
Shellac. In my opinion, shellac is the best natural wood finish for one main reason: it's the most protective natural finish on the market. Unlike other options, shellac forms a barrier on top of the wood, stopping water, dirt, and other things (*cough*crayon*cough) from reaching the pores of the wood.
If you leave furniture raw without applying a new coat of wax or poly you are taking a risk of your furniture drying out, cracking, swelling or staining. To limit wood damage, preserve furniture AND keep it looking natural you'll want to seal raw wood with Liming or Cerusing wax.
Most clear finishes are applied with a brush, working in the direction of the grain of the wood. After it dries, sand lightly. Then remove all the sanding dust and apply a second coat. For added durability, a third coat can be applied.
Can Water Seal be used on wood? Applying Water Seal will not damage wood, but the level of waterproofing protection will vary depending on the type of wood being treated. For best results, we would recommend a dedicated preserver to protect exterior timber from rot.
Cedar wood projects typically last more than 20 years without splitting, rotting, or warping. White oak and teak are also long lasting woods that are resistant to decay, twisting, cracking, or warping.
Untreated Wood
Left in their natural, unfinished state, most woods deteriorate quickly when exposed to outdoor environments. However, there are several species that have naturally occurring chemicals that help them shrug off harsh weather and insects.
Although treated wood is protected against decay and termite attack, the application of a water-repellent sealer to all exposed wood surfaces is recommended upon completion of construction.
Wood can Start to Rot in 1-6 months If:
Wood is untreated. The wooded area is sitting in water. Water and/or air space is hot & humid.
How Long Does Pressure-Treated Wood Last? 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.
A kitchen staple, white vinegar is a natural way to clean a number of items. It is also safe enough to use on unfinished wood, though never apply it straight. It can be used to remove general grime, but also fingerprints and is a natural way to kill bacteria if you do not want to use dish soap.
Paint protects the wood and also seals the tiny cracks and gaps that you might not even know exist in your building's exterior. These small blemishes start to get bigger if they're left without any treatment. Sooner or later, you'll have to deal with a much larger and more expensive problem.
Some say that untreated 2×4's can last up to two years before showing signs of rot and others say it can last even longer. When deciding if you should you use an untreated 2×4 it depends greatly on the application, how much weather and sun it's exposed to and if it's making ground contact.
For example, Teak doesn't need any treatment which prolongs its lifespan because it is naturally durable and doesn't have much movement whereas kiln dried Oak does need treating to prevent it from: Losing moisture and shrinking in the summer.

Answer: The manufacturer of Thompson Water Seal recommended that you use their product with a plastic sprayer with a brass wand, such as our Chapin Premier sprayer. There are no concerns about it eroding any of the seals inside of it.
Polyurethane wood finishes are synthetic coatings that are highly durable and water resistant, making them the best clear coat for wood protection.
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.
Yes. If you prefer the look of bare wood, you do not need to use stain before applying polyurethane. Polyurethane in matte finish offers a subtle appearance and soft-touch feel, while providing the long-term protection of polyurethane.
