Paint Mapping After Stripping Wallpaper. And How To Deal With It

[@Kingtrollface259]

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

[@PaintingandDecorating]

Totally all preparation.. painting old is usually quick and easy.. but new needs more work..

[@robw4492]

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

[@PaintingandDecorating]

Your welcome thanks

[@richardmcdougall233]

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

[@jigsorla]

Thanks, I think it's called Toupret smoothing filler on the 15kg tub.

[@satori169]

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.

Painted my entire house interior in Leyland contract Matt, it's the worst paint I've ever worked with, flaky, chalky, peeling garbage after a few months with prep

[@TheNomadicTrader]

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

[@TheNomadicTrader]

Update: stripping the walls has battered the plasterboard but due to the wall construction (solid plasterboard not stud wall) I'm having to plaster everything. Almost done, having learned to plaster myself. Jobs coming along

[@touristtam]

[@AndreaHatton]

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

[@PaintingandDecorating]

Thank you glad we can help. 👍

[@ka5269]

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.

[@PaintingandDecorating]

Yes sometimes what looks like an easy job can turn into something mammoth. Thanks

[@spencercolgan]

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

[@stuartibbotson7179]

[@richarddenny7336]

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 .

[@wiredcer]

what does reseal walls mean and why do you have to do that?

[@PBYM79]

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 👍

[@ProfessionalPainterDecorator]

you're correct. PVA shouldn't be used, never taught that in college. peel stop or Gardz is ideal, Gardz being alkali resisting give you a good surface to work on.

[@PBYM79]

@@ProfessionalPainterDecorator Hi again Phil, yep absolutely loving the gardz at the moment. Very reasonably priced too. 👍

[@DavidEast-i7r]

I would probably apply lining paper or plaster the walls in this case .

[@ImInMyShed]

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.

[@Ralphs-House]

I've got an area under a bay window (30s house) which seems to suffer from condensation in Winter as its a cold outside wall. I'll be using 3mm self-adhesive insulating paper, caulked around any edges so its secure, rather than paste-on stuff to stop this happening. I do have paint mapping - mostly firm paint but some exposed plaster. Seems solid though. Have used a mould remover and have a Dehumidifier running for a day or two to make sure wall is absolutely bone dry first. Once it is, I'll almost certainly use No-Peel on it, allow that to dry then fit the self-adhesive paper. Do you think that will be sufficient?

[@MrChristiangraham]

Ace work. Thanks for the tips!

[@PaintingandDecorating]

Thank you

[@nickbarsby3378]

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.

[@MrVocalist101]

Zinnser peel stop is good for this, did it a week ago and came out perfect, backing paper was in great shape so I just stabilised it with said product and new paper went on lovely.

[@TheOlzee]

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?

[@stevealderman2049]

Just seal it with Zinsser guardz or peal and seal

[@gray3553]

Agree Steve, I never use PVA.

[@samr7372]

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

[@deemdoubleu]

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).

[@ted5669]

PVA and paint is a big no no

[@spencercolgan]

Please explain what’s a “miscoat. “

[@fhellman]

in the UK a mistcoat is a coat of thinned down cheap emulsion that goes on bare plaster surfaces. The idea is to seal it. Then it's ready for decorating. But in the video he opts to use diluted PVA for the same purpose.

[@spencercolgan]

@@fhellman thank you!!!

[@MrJimtimslim]

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.

[@NiktheEnglishGreekCypriot]

I just spent 1700 on a bundle. M class extractor, and the deos and deros. Took a bit of getting used to as they kept bouncing off the surface but love it now.

@@MrJimtimslim yeah get ya mate. I was debating festool but I spoke to a few of the decorators i see in crown who all regretted the festool after trying mirka. Horses for courses though. Only downside with mirka is you have to hold down the trigger which can get tiring

I was hoping to see this comment, exactly what I'm thinking to do.

[@pdureska7814]

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.

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.

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

[@ka5269]

How much will that cost, though?

[@DANMCMAHON08]

Hardly anything in it you will find decorators always find a way to try and bring the wall back to life with it be lining paper or filling and sanding as they can’t plaster ..me personally I can do both and plastering is the easiest and better finish 100%. The problem with this particular method in this video is you’re still not going to get a perfect finish !!!
