Rated 5 out of 5 by from Does what it says on the tub. Used over 100 tubs of this stuff over engineering brick, concrete and other difficult substrates without a single failure. Wouldn't be without it. To the guy above, I suggest if the bonding agent is still on the wall solid the problem is with your cement mix or other as this stuff is top notch.

Can this be used to contain dust on a cement garage floor?

Asked by: StreetLife12
Hi. No this is not suitable for this application. You would need a concrete dust-proofer for this.

Hi, Rendergrip is a water resistant polymer (similar to SBR) with aggregate which will provide a key for render applications.
