Deck waterproofing is the process of applying coatings to make sure that the structure remains unharmed from either water or heat
. Waterproofing companies suggest the decks to be waterproofed 30 days after completely building it. This is the best time to waterproof floors and other aspects of the deck because it's brand new and there are no existing damages yet. Do not wait until you see signs of deck damage before actually doing something about it. You will pay more than having it waterproofed from the start.
