Render / Plaster / Stucco....oh my

[apj101]

Hi guys

I have a small brick outhouse
Interior brick work looks crap, non matching brick, overall not what i want (it will be my new workshop [small] )

what do i put on all the walls???
its pretty dang and a bit damp in there (though will improve when i fit new roof....stay tuned for questions on that is a month or 2)

So want to level out the wall surface with what i think they call Render/Stucco (basically the plaster cement stuff that hard as coffin nails)

I will be drilling and hanging a lot on these walls

Any suggestions!!!! Thanks

If the surface is sound, and not painted you can render on to it with a 4:1 scratch coat and a 5;1 float coat. Use water proffer in the mix to keep out the damp. I would not skim it, just rub it up and sponge it.

Let the walls dry out after you roof it, though, before you render.

Ah, it is currently painted in what look like a white wash

how does that alter my options

Thanks

Well, if you render onto paint, you are only sticking to the paint, not the wall so your render is only held up there by the strength of the bond between paint and wall.

I would see if you can get most of the paint off, maybe rake out the joints.

You could score it with a 4'' grinder.

You could then SBR slurry it, and render onto that.

The fool proof way would be to fix EML or Riblath (types of metal mesh sheeting) and then you could render on to this. Expensive and time consuming though.

See how you get on with getting paint off first.

when cleaning off the paint, how about running over the brick with a wire brush attachment on the drill

If i score with a grinder, how many scores?
