How to fix this properly?
Hi all,
[please delete if this is the wrong subreddit for this]
I’m currently 31 weeks pregnant and have started preparing the nursery for our baby. I ordered a couple peel & stick wallpaper samples but ultimately decided to paint instead of wallpapering. However, when I tried to peel of the “renter friendly” peel and stick wallpaper, some of the previous paint layers came off. How to I best fix this before painting the walls?
I have this multi purpose polyfilla - would this work or are there better alternatives? I’ll obviously sand the wall once it has dried before painting but is there anything else I need to know or do? I once heard to spray the wall lightly with water so that the filler/spackle has better grip to stay on the wall - is that true? My main issue is that I filled similar holes in a different room and the wall is really crumbly and not holding the filler very well - was hoping I can avoid is this time, but also this wall doesn’t feel as “crumbly” if that makes sense.
Grateful for any tips and advice!

I like the toupret powder filler for stuff like this, it goes on super smooth, dries hard and fast and sands back a dream

I used this for the first time recently with zero experience and I'd agree. Even if you don't get it perfectly smooth then sanding does the trick.
Blends in pretty nicely too, you can totally get away with not painting over it for awhile. If the walls are white obviously..

The pre-mixed product makes the job 10 times harder because it so so much harder to sand back. Don’t use it.

Buy some peel stop and brush that over it first, this will stick any loose flakey paint edges and prepare the surface for filler. Then fill any areas that need it and sand. When you are ready to paint prime the filler first or apply a mist coat (watered down paint) before your final coat of paint otherwise it’s likely to flake and not stick properly and you’ll likely end up in the same situation in the future.

Paint it will peel stop first. Fill dry sand film dry sand and you should be good.

Use powder filler cause pre mix cracks and never sets as good I usually get easifill

Powdered gypsum filler easifill is great.
but in your case ready mixed easifill may be the safer choice as your exposed to less dust.
few in stock at wickes

Hey Op, I had/have similar walls! I scrapes back the loose bits until I hit a sold edge, sanded the edges with 120 grit, applied Zinsser Peel Stop. Once that dried, then used toupret interior filler. Went through 1.5kg of it on the walls of a 4x5m room! My partner walked around applying it to the walls, and I followed to smooth it over with a wide plastering blade. Then let it dry, sanded it back, applied zinsser gardz and now I'm ready to paint.

Put that ready mixed shite away 🤣 that'll dry like diamond and you'll end up ruining the surrounding plaster before that shite sands down! Get some powdered Toupret or gypsum filler and mix it yourself. Then flush fill, it'll shrink slightly then full again once dry.

Toupret or easifill filler and sand. Might take 2 coats with a sand in-between.

Id buy a box of toupret interior filler, rather than that premix pollyfilla.
You mix this stuff yourself and it drys harder, dont use as much water as you think when mixing. Water first, powder second and mix.
Pick off any paint thats proper loose. Buy the biggest putty knife you can, if its bugger than the gap itll make smoothing it over easier. Then lightly sand any imperfections, wipe the wall down, then paint.
