Best Coatings for Wood Decks | Wood Porch Floors
Every year homeowners look at a wooden deck or porch and wonder: How well is that wood holding up? How can I restore the look I want? Is there any rot I can’t see? Am I going to put my foot through this step the next time I’m carrying a plate of burgers out to the grill?
You may think your only choice is to live with deteriorating surroundings or pay for extensive repair. However, by applying a seamless moisture barrier with ArmorThane’s spray-on polymer coatings such as polyurea or polyurethane, our dealers can repair existing damage now and prevent problems for years to come. Besides protection, color and design options open all types of possibilities.
What Goes Wrong with Wood?
What homeowners don’t realize is that conventional wood coatings such as paint, stains or other sealers look good at first but eventually wear through to the bare surface. Water seeps through cracks and worn or damaged areas.
We have all seen wood warp, discolor and eventually rot when exposed to harsh weather – cold, moisture, heat and UV sunlight. Temperature changes expand and contract wood then standing water accelerates the damage. The sun dries out wood and causes it to darken and turn gray and eventually crack. Power washing wood to remove dirt and mildew wears down conventional surface coatings and the etching causes permanent damage. The older the wood, the worse the results. Pots and planters that sit in one spot trap moisture for long periods. Deicers also discolor many wood finishes.
With wood, the most important step for long life and low maintenance is to block moisture from soaking in. This requires a seamless barrier also called a “waterproof membrane” and can be done in a couple of ways. The spray-on nature of ArmorThane polyurethane and polyurea materials allows for easy coating protection.
Because decks are often built with strips of boards, one approach is to encapsulate each board before putting a new deck together. Unlike surface coatings, this prevents damage caused from water seeping between boards and the moisture that can build up underneath the structure. This method also preserves the architectural look of a slatted deck or balcony. The problem is that it cannot be used on an existing deck, unless the boards are wide enough for complete coating between the slats.
The best approach is to use large sheets of plywood and seal all visible seams. When ArmorThane polyurethane or polyurea is sprayed over the entire structure it creates the seamless membrane.
To ensure a seamless waterproof barrier, an area to watch is where the deck or porch connects to another structure such as the house, patio, fence or even supporting beams. Watch for the next article on how this works best.
