How to Use This Calculator
Enter tile area and select tile size category. Choose trowel notch size (shown on trowel). Larger tiles need larger notches for proper coverage. Calculator provides bag count.
Why Accurate Thinset Coverage Matters
Trowel notch size determines thinset thickness and coverage. Wrong notch causes insufficient adhesion or excessive costs. Tile manufacturers specify notch sizes for warranty compliance.
Common Mistakes to Avoid
Using wrong trowel notch size, not back-buttering large tiles, letting thinset skin over, inconsistent trowel angle, and not checking for proper coverage.
