Treated Lumber Cracking – STOP Cracks By Using Great Sealer Below
Treated lumber cracking happens because water soaks into the wood. The wood swells creating stress within the wood’s cellular structure. When the water evaporates, the wood shrinks. This movement causes tension forces that start to tear the lumber apart.
The cracks you see are the visible signs of this tearing apart of the wood fibers. This is why wood is classified as a hygroscopic material.

The cracks get deeper and wider because they allow water to soak deeper into the wood. This acts like a wedge splitting apart firewood.
