How to Waterproof Your Deck

Waterproofing the deck that your family barbecues on or that surrounds the pool is an important thing to do if you want your deck to stand up to the weather for a long time. Warping and cracking will eventually happen to every deck made of wood, but what waterproofing will do is slow this process down quite considerably and the sealant will keep out most of the moisture that is placed upon it, whether it is rain, snow, or pool water.

If you wish to waterproof a new deck, it is best to wait at least 30 days before doing this, since the chemicals that the wood was treated with before installation need time to evaporate. Give the wood time to adjust to the climate. After you have waited this long, it is safe to begin the waterproofing process.

Start with cleaning off the surface of the deck and removing all debris. Also remove all patio furniture and equipment such as barbecue grills. The deck should be completely cleared off. A deck cleaner can be bought at most hardware and home improvement stores. Follow the instructions and you can apply this with a pump sprayer. When it starts to foam, start scrubbing the deck with a stiff bristled brush. This will make sure that the stains on the deck, almost no matter how stubborn they are, will come up. Rinse it off completely with a garden hose, but make sure you have on eye protection to keep anything from spraying into your eyes.

This is the time to apply the sealant. Spray it onto the deck with a pump sprayer or a roller. Sometimes there will be puddles of sealant that will form and these need to be rolled out evenly over the deck. Allow it to dry completely and after two days, you should be able to walk on it without damaging the seal.

When you apply sealant or any chemical to your deck, you should always wear eye and skin protection.

If you want to help keep your deck further waterproofed, you can drill some small holes into the areas of it that retain water on a regular basis. These holes can be as small as 3/16 of an inch to even ¼ of an inch and they will not adversely affect the appearance of the wood very much. They will, however, help keep the water drained.
