cpi over stonework/other surfaces

[User___removed]

i have a large gable(110m2) to render,and as i now have a machine was hoping to use cpi.i know its ok to spray over blockwork but is it ok over stonework? also instead of a tyrolean scat for a key like i normally would go about it,what can i put through the machine?

Rendaid,Hp12 or the easy option with just the good old paint brush Micro:RpS_thumbup:

cpi do a high bond as do 0ther maufacturers or you could whisk up a sand cement sbr slurry and pour it in the hopper to spray.

CPI and sbr makes a nice purple slurry which can be painted or roles on. You could spray it as blones said but to be he honest unless u have the spray finish kit its a bit pointless and mess

 

[Curry]

Just use high bond from CPI with mesh as your base or scratch coat. Then top it with CPI at 10 mm

Overall cost won't be to much more and will be much quicker then priming the wall, then scratching and then topping.
