SET Control®

Rapid Set® SET Control®: Slows Down the Setting Time

When you need to slow down the setting time on your job, SET Control® gives you more time to place and finish your concrete, mortar and grout materials. More time is often needed when your project involves large or intricate placements (more than one cubic foot) of grout, mortar or concrete. And in warm weather when cement naturally sets faster, SET Control® slows down the hardening of the cement. Use with Rapid Set® cement products and most other packaged hydraulic cements.
