Does Grout Need to be Sealed
by Denise Troiano
As a Product Support team member, I get asked this question often. The answer is simple, no, it does not need to be sealed. The better question would be, “Should I seal my grout?” Grout is a cement-based product mixed with chemicals, water, and in many cases sand. Portland cement based grouts are particularly porous.

Large and Heavy Tile Mortar Basics
by Dan Marvin
For thousands of years , tiles were a few inches across because those sizes were easiest to make and fire in a traditional kiln.

Crack Isolation Basics
by Dan Marvin
We've all seen them - unsightly cracks running through tile floors. While ceramic and stone flooring is durable, it can't overcome the laws of physics. When cracks open up in the substrate below, they often will telegraph up through the tile (and grout). Anyone who has chipped out several tiles to replace them can tell you - it is not fun project. The answer for most installations is the use of ...
