thank you you are epic of knowledge thank you

Great info from n this video. A very common problem in the States as well

Ace work. Thanks for the tips!

done a whole house that like this once ,was glad to get it done ,but it was a propper ball ache ,most people dont realise whats involved in painting ,especally with regards to bare plaster

Thank you for this. I bastardised another of your tips for this problem. After cleaning I mixed a hard stop of fine filler and emulsion and skimmed / filled the wall, followed by a very light sanding. The result was perfect and was paint, not paper. Surprisingly quick too. So thanks x 2

I have just exposed a wall like this. Your video is super!!! I have really learned a lot to tackle this problem.

If your paint mapping is quite thick from multi coats I would advise after scrapping/sanding and applying the diluted pva skim the wall with a fine filler. I use KNAUF FILL AND FINISH LIGHT. It's easy to apply with a large spatular or filling blade, and when dry easy to sand flat. This will ensure a proper flat wall surface if you want as flat a surface as possible. Large tubs of KNAUF fill and finish are around £40ish in the uk.

What’s the dilution ratio for a mist coat? Thnx Sam.

I've just bought a 5 bed 1972 house that's wallpapered throughout 😅 - I'm tempted to take the walls down and re-plasterboard, it'd be much quicker haha

Toupret fine surface filler is a game changer for very smooth fine dents even like different thickness paint or even bad plastering, saved the day on many an occasion. B and Q do large 15kg tubs. Toupret is a no grining/flashing filler

A good few years ago, I faced this horrible predicament after deciding to rip the wallpaper off in my bedroom. I was in tears, stumped over what to do about it and there was no way i going to skim the walls. In the end i made my first attempt at lining the walls. I would have tried this method if I knew of it.

i have an issue with paint mapping on my walls after stripping off wall paper. some panels i had virtually none and other its fairly bad like 50/50 with remaining old primer and plain drywall. Just for clarification. Mist coat is a priming coat yes? and the PVA primer you are using is diluted with what? Is the dilution 2 to 1 or 5 to 1? Finally, you gave the option of just doing a priming (mist coat) instead of the dilute PVA step correct? I've read that PVA is really more for new drywall and then you put another primer over the PVA which seals the drywall. Then you put your one or two coats of paint over that. Is this a correct sequence. there was some issue with people saying you should not put PVA on a wall that has already been painted. Sorry for all the questions but yours is the only video i could find regarding the paint mapping problem so well done. i think i was worried my only option would be to put on a skim coat. Thank you.

I've found best solution steam off this old paint with a wall paper stripper let plaster dry repair any damage plaster.Reseal walls and repaint and hey presto beautiful new walls just like new the professional touch .

I know you said you’re wallpapering it but if you were to actually paint a wall with so much mapping you’d be better to line it or skim coat it or even Mirka it away? Not a diy’er but a decorator?

If stripping a vinyl wallpaper leaves behind a good sound backing paper, is there any harm in putting new wallpaper over the top - treating it as a lining paper.

Try a 12" squeezy mop and bucket, "paint" the wall with water, wait 3-5 mins then wet again, wait another couple of mins, then use a 12" wide scraper, flick the paste muck onto sheets of newspaper. Then repeat. The 2nd wash and scrape will really get it off. Finish with a wet sponge to get any residue. On concrete floors, no need to cover with sheets, upstairs thick, old towels are recommended to catch the excess water from the two soakings.

It's not the only way,zinsser guardz would smash that,times have moved on work smarter not harder.

Builders should be banned from painting inside houses (joke but no joke). They always seem to end up causing problems like this down the line (same in my house and I have had to strip a few walls down to bare plaster but this is very time consuming and noisy for the neighbours).

👍👍

This is pretty much how I was taught to deal with this. Thankfully tech has moved on a great deal and as pro's we can work smarter and not harder. I probably wouldn't have used diluted PVA to seal. I was taught in college and by my first employer to never, under any circumstances use anything with vinyl in it to seal bare plaster. My go to now is zinsser peel stop or gardz, but if it works for you guys then go for it. Great channel 👍

👍👍👍

Stanley blade will shift it

Sod that I will just wallpaper it with some superfresco

Brilliant...

Please explain what’s a “miscoat. “

Or...5 minutes with a mirka and its completely stripped off and flat. No cleaning of paste, all the paints gone and the wall is flat. Cost you 600 odd quid to set up though so not a diy solution but pro's... No brainer.

Just seal it with Zinsser guardz or peal and seal

Echo echo .. . Testing testing...

Lol just use a orbital sander with p80 sandpaper.... And then use like p120 then the p240 sandpaper! Seriously... 🤣🤣 just done my bedroom

What is water to pva ratio?

Remove vinyl or film of first layer wallpaper. Then dash of stripping solution or Fairy with hot water.. towels down to catch water on wall. Use roller and dip into the solution Roll wall with it and don't be shy. Wait 5 minutes an comes off easy. Then sand the life out of the wall. Fill any areas needed Then seal with zinnzer GARDZ or if your lucky if it isn't bad Zinsser BIN. Boom. Water doesn't activate shellec paint. Neither does oil.

Plaster skim, by the time you face fill etc

Stop using pva Zinsser gardz all day long

wow pva A

Cowboy here again with PVA. No paint manufacturer ever suggests this. Sand. Seal with diluted paint

just seal with a solvent alkali resisting primer then surface fill pva isn't alkali resisting

Difficult to understand the first 1/3 of your video, plus sound of 'ocean' in background... then sanding noise, etc.

Peel stop mist coat not pva

i have been painting 44 years . if i worked like that i would have no customers. you are what i call a hobby painter.

Or just stop all the messing around and get it skimmed with multi finish plaster and get a perfect new wall back !
