plaster repair patches before skim


Recommended Posts

Disclosure - I've only done small areas of plastering before, I usually get someone in but budget doesn't allow it on this project.

I'm going to be (attempting) to skim a couple of walls. They're generally sound but poor finish where previously tiled.

In a couple of places, where multiple fixings had been put through the tiles, and in another where some tiles had been glued to the wall with what appears to be epoxy, the plaster came off the scratch coat. The scratch coat is still firmly adhered to the wall, but in these places the plaster was about 5mm thick.

Before skimming I assume I need to fill those areas with plaster. Do I just use some of the multifinish to bring them up to level and let set completely or...?

Ive also got one wall that is not very flat where a wall has previously been removed. Deviates across a 1m long section by 6mm in a vertical cup. Best way to level that off?

Sorry I can't, one job I've never tried. YouTube would my next call though.

I did have a look before posting but didn't have much joy unfortunately! Loads on how to do the actual skim, not so much on prepping a less than ideal finish ready for it.

If you use easy fill 60 you can build the areas up in 2-3mm layers, you can also sand it back so you can feather the edges in. 
make sure you primer the deep dry areas. 


Thanks Russell. I have a bag of easifill sat here but wasn't sure if it was wise to put under the final skim coat or not. I'll crack on!

Ah got ya - I need to skim coat as the rest of the wall has lots (seriously lots) of little imperfections all over it, I just wasn't sure what to do about the couple of larger, deeper patches before skimming it. I assume from the depth that trying to do in one hit with the finishing plaster would be a bad idea (would end up 8mm deep in those places!
