- Rain resistant
You should choose an outdoor wood sealer that is rain resistant which doesn’t let water droplets from rain or snow get into the wood. This means that when the weather is rainy or snowy you can wipe off the moisture and the surface of the furniture or surface will still be dry. Linseed oil and Tung oil are some of the ingredients that are rain resistant and durable. Look for wood sealers that have these two.
Look for wood sealers that are defined as ‘marine paint’ as this means that they can withstand prolonged exposure to water and not let water into the wood. That means that they can also withstand floods so they are perfect for outdoor wooden furniture. Other sealants also use lacquer and varnish. Marine varnish is the best type because it also prevents damage from UV rays, so your furniture can stay in the sun without getting too much damage.
- Easy Application
When it comes to sealing wood, the better option is one that can be applied easily. This will mean less coats of sealer needed which means you’ll save time and money! It’s also important to make sure your finish dries quickly so as not leave any patches left undone once the sealant has been applied onto the wood. Make sure that the sealant cures easily so that it will not become tacky and sticky, giving the wood an old or unpleasant look.
- Non Toxic
Non-toxic sealers are not only better for the environment, but they also prevent any potential harm to your furniture’s surroundings. Some wood sealer products may show toxicity until cured, so don’t forget about that either!
- Mold Resistant
You should look for an outdoor wood sealer that will prevent your wood from becoming moldy when exposed to moisture. Mold can spell disaster for your wood because it will soon change color and the appearance will not be what it once was.
Some sealers are more suitable for furniture while others are best for larger wooden spaces such as decks/patios. You can do some research to see which sealer is suitable for your purposes.
