painted wall

[plasterjfe]

pricing up a monocouche job for a pal, its onto brick but ther is 1 small section of white painted wetdash render, i never applied mono over painted before, I have used other systems over painted using rendaid or wall conditioners such as dryvits prymit or other bonding agent or even mechanically fixed insulation first but i wanted to know what you lafds recon? the wall is sound not flaking but should i take the paint back?

i would take the paint back and rake the joints out, thn rendaid and mesh the hole lot.

 

[spunky]

can you do mono straight over brick ???

 

[simplybesty]

you can and some do but i wouldnt recommend it

i'm on a job doing just that at the mo.....going over porous face brick..... been advised so we've used parex microgobetis which provides a sandpaper like key as well as killing the excessive suction. done a splash test but not rendered it yet and the suction seems slower than block now.

was gonna use krend with hpx backing coat as its onto brickwork but I could do with a cutting tool that will scuff the paint off. any ideas?
