Plastering over a cracked painted solid wall.

[Johnpalmer]

Hello I'm used to skimming straight onto plasterboard, I've got a slight crack appearing in the middle of the solid painted wall. Do I remove any lose bits and bond over the holes that it would create and then pva the whole wall and skim straight over it all? Or would I put joint tape over the cracks then skim over them? Or can you even skim over painted walls. Any help would be much appreciated thanks.

Where did you learn to plaster? How was this now covered on the course?

Remove any loose bits, if the crack is big, eml it and mechanically fix,if not ,bond and plastic mesh and skim

Hack off the plaster yo expose the crack.. if its just blown plaster due to peril.. bond n skim.. if the brickwork/blockwork is cracked. Rake out the crack fill with a epoxy resin. And mechanically fix eml n bond up n skim.. pretty much the same as johniosaif said..!! Thumbs up

you should check the crack is not structural first, I know of someone up the road from me who's front of their house nearly fell off, started from a small crack, if it's on one of the inner walls should be ok.

Good point ray. Check if the crack is same outside... helical bars may b needed or seek structural advice..!!!
