Why You Should Upgrade Your Deck Lumber

John Temmel Siding Guy
by John Temmel Siding Guy
Standard lumber goes through a pressure treatment process before it gets shipped: the wood gets injected with chemicals to preserve it so that it won't rot. When the wood reaches the customers, there's about 40% moisture in that wood from the chemicals. What does that mean? When you build your deck, the wood will dry out because the moisture tries to escape, which results in a cracked and unpleasant looking deck after several months. The best way to get a beautiful, quality deck is to obtain wood that goes through the following process: Kiln-Dried-After-Treatment (KDAT). During this process, the wood is placed inside a kiln and dried so that when it's delivered to the customer, there's only about 15% moisture in the wood. It's much more expensive but worth it!
