Frequently Asked Questions
What thinset thickness should I use?
About 3/16 inch, the default here, is typical for a standard notched trowel used with most floor and wall tile. Larger format tile or an uneven substrate may need a thicker bed, check your trowel notch size and tile manufacturer instructions.
What is a standard thinset bag size?
50 pounds is the most common bag size for thinset mortar in the US, the default here, though some products come in smaller bags. Adjust the bag weight field to match your specific product.
Does thinset thickness vary across the whole floor?
Yes, in practice trowel ridges get compressed unevenly and some areas need more material to level the substrate, so this calculation gives a reasonable average estimate, not an exact figure for every square foot.
