Questions & Answers
1 questions

Area coverage per bag with system easy to use liquid/ dry combination. My area for tile coverage is 355 sq ft.?

There are a few variables in regard to how many bags it would take for 355 sq ft. Such as tile size, which trowel you'd be using as well as how thick you'd need to lay the mortar. This job can take anywhere from 6 to 12 bags depending on the options you chose.

Backsplash in a day!

by Hunter J.

This stuff is super creamy just like mastic and spreads much easier than the premixed stuff from other brands. You wont believe how fast you can get on to grouting. use with Ardex Fl and do a backsplash in one day!
