Frequently Asked Questions
Q: Why is a waste buffer allowance necessary for surface calculations?
A: A waste buffer of 5% to 15% covers broken tiles, corner angle cuts, pattern matching alignment, and shipping mistakes.
Q: How do I calculate the area of an L-shaped room?
A: Split the room layout into two distinct rectangles, calculate the area of each separately, and add the two totals together.
