Waterproofing the deck depends on what benefits the user is looking for. The best products work to repel water, preserve the wood and screen out UV rays.There is a choice between an oil- or water-based product.
There are significant differences between water- or oil-based finishes. Oil-based finishes provide more protection and last longer. Oil-based finishes also penetrate the wood more. Water-based finishes are easier to clean. Water-based finishes are also better in damp environments. Another choice to consider is to use a finish that is clear or with color. The more color that the finish contains, the more protection it provides for the deck.
