what should moisture content be for hardwood floors
Air humidity can affect your flooring just as much as spills or puddles. The first thing you should do is check the moisture levels in your home. Humidity outside wonât affect your hardwood as long as the moisture levels remain between 35% and 55%. If the levels are over 55%, thereâs a greater chance of enough moisture seeping into the wood so the floors swell.
In most cases, your installation will probably in a zone with RH values between 40% and 45%. If the temperature of the building is between 75 and 85 degrees, the equilibrium moisture content of your wood should be between 7% and 8%. However, in some coastal areas, the average RH is in the 58% to 63% range.
