Rendering over painted brick wall

[chappers]

I agree with joe I would rake out the loose pointing and then cut the brick faces up with a grinder and render over

beg to differ joe but there are cheap mesh an fix solutions,means nothing if the scratch dont stick to the substrate,the mech fix will hold,to the op fix the water ingress first,then render!

I've seen far too much mesh rusting and falling off. I'll stick to the tradition of bonding to the substrate thanks very much.

yes but surely if its made from stainless steel it wont rust and fall off?

do you mean run a 4 " grinder down the front of each brick cutting a groove? if so how many per brick? two?

stainless steel mesh?bigest cause of cracks for any render system,were the mesh doubles and trebles,(on mesh overlaps ),gets hot in the summer expands more than the render an cracks,shape up boys and keep up with modern building methods

i would personally use a 9" and criss cross over the whole wall with lines about 100mm apart, but a 4" would be fine you dont have to go mega deep
