How do you store treated lumber to prevent warping?

Store your lumber in a clean, cool, shaded and dry location. If you’re storing wood in an area with high relative humidity—80 percent or more—be sure it’s wrapped in material that is impermeable to vapor. This prevents the wood from absorbing significant amounts of moisture from the surrounding air.

Why is my pressure treated wood bowing?

When wood gets wet, it swells. When wood dries out after being sawn from the tree, after being pressure-treated and after rain showers, it shrinks. Uneven drying creates stresses in wood, which results in warping (e.g., bowing, cupping or twisting) or cracking.

Does sealing wood prevent warping?

Sealing wood will not prevent it from warping or expanding. Sealing both ends of the wooden plank may help prevent the ends from expanding or shrinking faster and exacerbating the warping of the plank. However, there is no guarantee treating wood with a wood sealer will prevent it from warping or expanding.

Can you put sealant on pressure treated wood?

However, most pressure-treated wood should have periodic sealing against moisture, preferably every year or so.

What happens if you paint pressure treated wood too soon?

Does epoxy keep wood from warping?

Some finishes slow moisture exchange better than others, and all finishes do this better the thicker they are.
