Frequently Asked Questions
What grout joint size should I use?
Rectified porcelain tiles with precise edges use 1/16" to 1/8" joints. Non-rectified ceramic tiles with slight size variations typically require 3/16" or 1/4" joints.
How is grout powder weight calculated?
Grout weight depends on tile perimeter, thickness, joint width, and total area. Thicker tiles and smaller tiles (like subway tiles) require significantly more grout.
