Rendering over painted bricks

[Freerider]

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!

 

[spunky]

You need to fix eml over the top really mate or get the paint off then slurry it

 

[Freerider]

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?

grind out the joints an needle the rest then sbr

 

[spunky]

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

i know what your sayin mate an totally agree but me i always like to get it off then ya know its right

 

[Freerider]

cheers guys!

 

[beddy]

[Freerider]

This time I will just grind up and SBR as it aint a huge area, but cheers guys will remember to EML next time!

there slow spunky but a useful tool. If it was me and the paint was sound betokotack the walls.

 

[spunky]

Can you use it on externals?

 

[Freerider]

Can you render onto betokontakt?

 

[henry]

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

I reckon it'd be a tad quicker lol

 

[henry]

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.
