When placing a long piece of flooring, what should be the distance from the side wall to the grooved edge?

The correct distance from the side wall to the grooved edge of a long piece of flooring is typically between 1/2" and 5/8". This spacing is essential for allowing expansion and contraction of the flooring material, which can occur due to temperature and humidity changes.

Such an allowance helps to prevent buckling or warping of the flooring, ensuring it remains secure and maintains its integrity over time. The 1/2" to 5/8" distance is a standard practice in the flooring industry to accommodate typical variations in flooring materials and prevent potential issues that might arise from lack of space.

Understanding this allowance is crucial for anyone involved in flooring installation, as neglecting to provide adequate spacing could lead to complications and costly repairs down the line.
