Did You Know ...
Probably one of the two biggest myths about decks is that pressure treated lumber does not need to be sealed. This is false, pressure treated lumber will protect wood from decay and insects. However, all lumber still needs to be protected from the sun, water, moisture, snow and cold temperatures. If actions are not taken Mildew, Cracking, Graying, Fading, Sun Damage, Cupping, and Warping may occur. The other myth is that sealers that cause water to bead are good products, this is also false. What causes water to bead is the surface coating of wax and silicones. These are short lived sealers that break down quickly from foot traffic and the weather, just as a waxed car breaks down after a few months.
A longer lasting protection is gained from penetrating oil sealers that form a film within the wood and cause the water to sheet or run off. This is why we use TWP (Total Wood Preservative).
