The first board of tongue and groove flooring should be installed how many inches from the frame wall and which side of the board should face the wall?

The correct answer is based on the installation guidelines for tongue and groove flooring. When installing the first board, it should be positioned 1/2 inch from the frame wall. This spacing is crucial because it allows for expansion and contraction of the flooring material due to changes in humidity and temperature. If the flooring is installed too close to the wall, there may not be enough room for these natural movements, potentially leading to buckling or warping.

Additionally, the groove side of the board should face the wall. This orientation ensures that the tongue of the subsequent board can fit securely into the groove of the first board, creating a tight seam that enhances the overall strength and stability of the flooring. Proper alignment not only affects the aesthetic appearance but also contributes to the durability of the installation. Therefore, following these guidelines results in a professionally installed floor that can withstand environmental changes without compromising its integrity.
