Proper lumber storage prevents warping, checking, and moisture problems before projects begin. A few simple practices protect your wood investment and ensure materials remain workable.
Stack Flat and Level
Store boards horizontally on flat, level supports. Uneven bases cause bowing that becomes permanent over time. Use sturdy sawhorses or dedicated lumber racks rated for the weight you’ll store.
Use Stickers
Place uniform stickers (spacers) between each layer of boards. These allow air circulation on all surfaces, equalizing moisture content and preventing mold. Space stickers every 16-24 inches along the board length, aligned vertically through the stack.
Weight the Top
Heavy weights on top of stacks help prevent cupping and twisting as boards acclimate. Concrete blocks or additional lumber work well. The pressure keeps boards flat while moisture content stabilizes.
Control Climate
Store wood in conditions similar to where finished projects will live. Lumber acclimated to your shop may warp if moved to a much drier or more humid environment. Basements and garages with wild humidity swings cause problems.
Check Regularly
Inspect stored lumber periodically for insect damage, mold, or unusual warping. Catching problems early allows intervention before boards become unusable. Rotate stock so older purchases get used before newer arrivals.
Good storage habits cost nothing but attention yet prevent expensive material losses and frustrating project delays.
