Here is how you can keep fence boards from warping.
Wood fences can warp because of changes in moisture content that cause them to distort and not be as sturdy as they once were. When parts of a wooden fence dry faster than the others, they can shrink more quickly. The relationship between the humidity in the air and the fence’s moisture content affects a fence board warping.
Equilibrium moisture content (EMC) is when fence boards have high moisture and constantly shrink until there’s a balance with the air’s humidity. EMC can take days, weeks, and months, depending on the wood’s size, grain, coating, and air temperature. On the other hand, when the wood has a low moisture content, it absorbs moisture from its surroundings, causing it to swell until equilibrium. Here is how you can keep fence boards from warping.
