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.

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

Hi, can this be used on tanking slurry as I wanna waterproof exterior dwarf wall then render & paint? Cheers

Asked by: JAAAAAAG
Rendagrip will bond to tanking slurry to give a key for render but it should be noted that it will reduce the breathability of the substrate.

Is this waterproof in the sense that it can be used as a tanking slurry which can be rendered over?

Asked by: Gedub
Although it is water resistant, it is not a waterproofing product. It is a bonding agent that provides a mechanical key for rendering onto and should not be used as a waterproofing tanking slurry.
