Deck Waterproofing 101: Things You Need To Think About
Posted on: 30 August 2021
Whether you're building a new deck or you've bought a home with a deck that's been neglected, you should give serious consideration to waterproofing. When you waterproof your deck, you'll extend its lifespan by protecting it from water damage, and you'll also help to prevent pest infestations by sealing the wood so that the insects can't get in. If you're getting ready to waterproof your deck, there are some things that you should know.
Let New Decking Material Rest Before Waterproofing
If you're building a new deck, you may be planning to waterproof the deck as soon as construction is finished. After all, what better time to waterproof it than when it's brand new, right? However, if you try to waterproof the deck right away, you may find that the wood is still too wet to absorb the sealant.
You need to give the wood some time to settle, cure, and dry out before you try to waterproof it. Wait a few weeks after installation before you try to apply waterproofing sealant. If the rain still beads up on the wood, you need to wait longer. When rain soaks into the wood surface, you know that the wood is dry enough to apply the waterproofing sealant.
Start With A Clean, Dry Deck
If you are waterproofing an existing deck, one of the most important things you can do is pressure wash the surface of the deck before you waterproof it. Removing any dirt, debris, or grime from the surface of the deck will ensure that there's nothing in the way to prevent the waterproofing sealant from forming a seal on the wood.
However, remember that you need to let the deck dry after you wash it. Typically, you'll wash the deck the day before you begin the waterproofing application. That way, you can be sure that the wood is dry and ready for the sealant.
Consider The Weather
The weather has a significant effect on the final results of deck waterproofing. If the temperatures are nearing triple digits or the sun is baking down on your deck, the material may evaporate too quickly from the heat, resulting in poor or uneven application. If the temperatures are below the 50s, the wood may be too cold to absorb the waterproofing sealant effectively. Check the recommended temperature range for the waterproofing product you chose so that you can select the right day for application. Also, be sure that there's no rain in the forecast for a couple of days after application so that the waterproofing has time to fully cure and bond with the wood.
