repairing plasterboard after removing tiles

[noos999]

Hi all

I removed some old tiles in the kitchen, resulting in the following issues:

1/ In one area (20 x 30 cm approx) most of the underlying plasterboard came off when I removed the tiles. Luckily this area will have new tiles put on, so I don't need to make a perfectly seamless repair. Would the best thing be to cut back the plasterboard to make a clean-edged hole and cut a rectangle of new plasterboard to fit? The plasterboard had been stuck onto the underlying breeze blocks with a dab of something, can anyone tell me what I should use to stick the new piece of plasterboard to the breeze blocks? Can I use Easi-Fill to fill the gap between the new and old plasterboard?

2/ In another area, some more minor damage was caused: in places the top layer of paper on the plasterboard tore, so I'm left with brown 'furry' paper exposed, and in places bare plasterboard. I wasn't intending to retile this area, so I'm hoping to get the wall back to a suitable state to be able to paint over it. Would be sensible to try to skim over with Easi-Fill and sand down afterwards? Do I need to seal the brown furry paper and/or the bare plasterboard areas before using the Easi-Fill? Do I need to seal the Easi-Fill before painting over it?

many thanks for any advice on these topics

Use anything you like to go straight back to the breeze blocks. I'd go for bonding plaster but whatever you have will do

If you're retiling, the tub adhesive makes quite a good skim. Sticks well to just about anything and is fine enough to get a smooth finish. Not as easy to sand but it's pretty easy to get a good finish with a trowel.

Thanks for the info. In case 2/, I am not planning to retile as that section of wall will no longer have a floor unit present in the new kitchen layout. So I was wondering if Easi-Sand would be a suitable medium to smooth over the damage?

thanks
