Just looking for some advice on the best/cheapest way to resolve this...
I am about to repaint the whole inside of the house, but tge problem is that the finish is currently very rough. It was just a painted cement render. I would like a smooth finish.
So to be able to achieve the finish i could sheet the whole house obviously at quite a cost or attempt to add a skim coat. Do i need to sand the surface to get a key, apply some kind of primer or use a paint remover first?
Then what product would work best - do i mix up a lime render and roll on and use a squeegee to get a smooth surface.
Or trowel on and use a float?
What lime render to use or what is the alternative?
I did try using gyprock multi joint compound on a test wall and that seems to stick to the paint as is. It would mean sanding back though and hardly coat effective to do a whole house.
Advice much appreciated
