7 Best Outdoor Wood Sealer

Wood is beautiful. It gives your house a rustic look, and best of all it looks natural. However, wood needs to be taken care of otherwise it’s not going to last very long. If you have wooden furniture or extensions to your home outdoors, the weather is probably going to damage it quite a bit. A wood sealer is important in such situations. Check out our list of the top seven wood sealers below. This list has all of the best sealers on the market.

7. WholesaleTeak Honey Tone Finish Semco Teak Wood Sealer/Sealant/Protector

WholesaleTeak Honey Tone Finish Semco Teak Wood Sealer/Sealant/Protector

  • Rich honey color resembling new teak
  • Water based formula
  • Free of pigments
  • Environmentally friendly formula

If you have teak furniture, this sealant will work quite well for you. The WholesaleTeak Honey Tone Finish Semco Teak Wood Sealer is quite easy to apply as well thanks to the no drip formula. We also appreciated the environmentally friendly formula. This will make you feel less guilty while using it because of course no one wants to be responsible for harming the environment.

While this is a decent outdoor wood sealer, it is far from perfect. Hot or humid weather will make it sweat which means the color will run. A lot of customers have complained about it running clothes or cushions that were placed upon the wood because the sealer began to run. It is also not that waterproof, the color will start to run if it rains. Overall it is a decent sealer but there are a lot of better products out there.

Pros

  • Good for teak maintenance
  • Easy to apply
  • No environmentally dangerous chemicals

Cons

  • “Sweats” in humid weather
  • Not very waterproof

6. BOND DISTRIBUTING LTD 00200 Natural Wood Stain/Sealer

BOND DISTRIBUTING LTD 00200 Natural Wood Stain/Sealer

  • No drip formula
  • Comes in gallon size
  • Designed to prevent cracking, chipping and flaking
  • Age resistant formula

The Bond Distributing Ltd Natural Wood Stain has a no mess application process. It has a no drip formula much like the WholesaleTeak Honey Tone Finish Semco Teak Wood Sealer, but it is also superior in a lot of ways. First of all, it is a lot more waterproof than the previous entry on this list. Also, it is a beautiful natural look that brings out the actual hue of the teak.

A couple of problems you might face have to do with how this wood sealer has been advertised. It is supposed to last years but you will actually have to keep reapplying the sealant if you want its effects to last. Also, over a long period of time this sealant will also get ruined because of things like rain and other kinds of moisture. Overall, the main problem with this sealant is that it is not as long lasting as you might be lead to believe.

Pros

  • No mess during application
  • Has a natural look
  • Relatively waterproof

Cons

  • Does not last nearly as long as advertised
  • Long term moisture spoils color

The application process is easy, and there won’t be any greasiness to deal with. Greasiness can make the varnish dry slowly, so this sealer definitely has something going for it.

While this is definitely a cut above the previous two products on this list, it has a few problems that you might have to deal with too. The aged look is nice but some people will prefer a more natural color. Also, the smell can be a bit of a bother. You might have a tough time applying it because of how strong the smell is.  Also it is not as waterproof as you might think so cleaning the wood becomes difficult after you apply it.

  • Non-greasy application

Cons

4. TeakFurnitureCenter New Semco Teak Wood HoneyTone Finish

  • Designed for teak
  • Water based formula
  • Honey gold color

It brings out an original teak wood color which is perfect for people that like the natural color of wood. The smell is also a lot better than the New Semco Teak Wood Natural Finish Sealant Protector, as well as the fact that it is easy to clean. Additionally, this sealer can handle some major sunlight thanks to the UV inhibitors. This makes it perfect for outdoor use.

  • Penetrates rotten wood
  • Marine grade primer
  • Two part liquid, to be mixed
  • Available in warm weather and cold weather formulas

The Smith’s Original Clear Penetrating Epoxy Sealer is an incredible example of what a good sealer can be. You can actually use it to bring rotten wood back to life, so to speak. The sealer is absorbed into the wood and binds the fibers together. This repairs some of the damage that the rotting process might have inflicted on the wood. The sealer soaks in quickly too, which is also something that you will appreciate.

A couple other things are the saline resistance. Outdoor wood furniture is a pipe dream for people living by the sea, but this sealer can help make this dream a reality. That being said, you have to get a lot on there in order to get the desired result. This isn’t the New Semco Teak Wood Natural Finish Sealant Protector which gets the job done in a single gallon. Also the mixing process can be a little technical. Overall though this sealer deserves it’s place in the top three.

Pros

  • Can repair rotten wood by binding fibers together
  • Highly resistant to salty sea air
  • Versatile, can be used with other materials
  • Soaks quickly into wood
  • Durable after three coats

Cons

  • A lot needs to be applied for quality varnishing
  • Needs to be mixed which is a complicated process

A natural wood color is often hard to come by, but the Thompsons WaterSeal Advanced Natural Wood Protector actually makes it easy. This solves the multi coat problem that the Smith’s Original Clear Penetrating Epoxy Sealer has which is one of the reasons why it is ranked higher. The formula is very durable too, which fixes some problems you might face while using the Bond Distributing Ltd Natural Wood Stain.

You will also notice that whenever water falls on a wooden surface that has been sealed using this product it will collect into beads and run off.

  • Only needs one coat to work
  • Long lasting formula
  • Efficiently beads water

You also get a truly long lasting formula, there is no false advertising to deal with here. Easy application comes with the territory since this is a grease free formula.
