Waterproofing Your Deck

A water damaged deck tends to be an ugly one, as most people know, but waterproofing is not that difficult. Waterproofing your deck is essential if you want it to stand the test of time and seasons that it will go through even after you are gone from the house that you call home. Cracking and warping can occur to any deck, but waterproofing it can help assist you in removing the majority of this risk, since the water sealant will lock out the vast majority of any liquid spilled onto it.

The waterproofing of your deck has to start with a thorough cleaning first. The best time to waterproof your deck is after the deck is first built, but if you do not have this option, then cleaning it off is the first thing that you have to do. Begin by sweeping off all the debris from the deck and removing all furniture from it. A cleaning solution can be bought from home improvement stores. A pump sprayer can be used to apply the solution to the deck. After it starts to foam up, you need to scrub the deck with a scrub brush that has stiff bristles. This will help to remove many of the stubborn stains that might exist like grease or soot. After you are done with the scrubbing part of the project, you can rinse it off thoroughly with your garden hose. When you rinse, wear some eye protection to keep any grit on the deck from getting in your eyes.

After your deck is dry, you can do one of two things. If the wood is relatively new and you think you want a new stain put on it, this would be the time to apply it. If you do not want a new stain on the deck, then this is the time for you to apply the water sealant onto the deck to protect the wood.

Applying the sealer should generally be done with a sprayer or a roller. If there are any puddles of it on your deck, you can remove these by brushing it out evenly. The deck should dry completely in about two days and then you can walk on it safely without having to worry about damaging the sealant.

Always follow the manufacturer’s instructions when you apply the sealant. Wearing safety glasses, long sleeves, and some gloves is also a good idea to protect your eyes and skin from it.

Drilling very small holes in areas of the deck that tend to retain water can also help stop the weathering of your deck. Holes as small as 3/16 of an inch to ¼ of an inch are sufficient to drain the water out of these areas and do not tend to affect the appearance of the deck enough to be an eyesore.
