Got a rendering job tommorow, over painted bricks, would an SBR slurry be sufficient on its own or do you recommend I get the grinder out too?

cheers fellas!
 
As I havent prices to eml it would angle grinding them up and SBR be sufficient? not a massive area! also why would you SBR it if you removed the paint? surely theres no need then?
 
Depends on what's underneath mate if it's a small area and it's ******* right on there then carry on, it's the weight of the render on The paint you're not fighting the key it's the risk of pulling the paint off
 
there slow spunky but a useful tool. If it was me and the paint was sound betokotack the walls.
 
why not if it makes a sound surface to render on then why not with these jobs it is always the suction it will just hang . Keep your render tight and mesh like spunk was saying. Spunk about 3 years ago I did it on a external walls on a bungalow which had the old large stone dash and about 30 coats of paint on it.
Anyway after a wirebrush painted the betokontak re render sponge finish and the rest is history. Still looks ok today. Hey spunk you can even spray it on with the pft xl so I read on a german pft web site.
 
Lol just been looking through the you tube vids, were starting a job Thursday 1100m of concrete to betokontakt and skim would love a little ritmo mate
 
You will be useing the the large tubs then spunk just make sure you give it a quick wisk before useing it. Them putts your on about are use a lot on lindsey oil them lads who spray that fire re***d gear all use putts so am told .
 
betokontakte is for interior use ie concrete & insitu concrete for pretretment of dense none absorbing backgrounds before plastering used it on mr boards & artex DOESENT MENTION EXTERNAL ON THE TUB put it on with a roller £53.00 for a 20kg tub from ccf :RpS_thumbup:
 
I've used it once on outside walls - on a conservatory, so if it failed it would only be a small bit to replace. That was about 4 years ago and I still give it a little tap now and again to see that it's alright. So far, so good! Gotta agree though - it is supposed to be for internal use, not external.
