Render grip

[djplasterer]

Hi there just a quick one a builder has asked me to supply rendergrip and apply to a painted brick wall before rendering it.just wondering has anyone used it on a painted wall or shall I just insist on sbr slurry thank you dominic

I've used it before on a very small area on paint and it's still on,wouldn't use it again for that but it's just because I had it at the time and was on a tiny garden wall.

Render grip is a product by ever build I think, I have a tub in the van, only used a bit and it seemed ok.

expensive though, I think micro goes further and you get more for your money.

I have used it.although it's not meant to be used over paint.for use on engineering bricks,concrete or similar.
The risk is yours to rake

What ever render you use wether it's s&c or mono,it's a lot of weight on the wall so whatever product you use your taking a gamble for sure.
I only use a thin coat system over paint now
