'Filling' blown skim coat.

[AJoe]

Morning all.

I'm currently in the process of stripping woodchip from a 4 bed house. I know...

First room has one wall with a lot of blown skim coat. The sub base underneath is sound.

I'm considering getting a tub of Knauf or Dalapro to 'fill' the entire wall, but I was wondering if anybody had any experience doing this over what is now a very uneven wall with big patches of missing 1mm skim.

This is a picture of the wall. Obviously I pull back any loose plaster and PVA it to stablise, but my real question is whether Knaud Pro Roll Max (for example) is capable of taking up the 1mm patches and the wall that's still sound without looking like crap.

For the record, I am the worlds worst plasterer.

If you used a steamer on that paper lob it! Do more damage than necessary.
I'd sand wall.
SBR
Plaster.
Just watch.. on the trowel... How to on YouTube. It's not difficult to get somewhere near then bodge a cheapo orbital sander on a vacuum and with 120 grade discs sand over.

As for your question.
Proroll imo is harder to use. Don't set in an hour like plaster.
Air dries so you can only get one skim on in a day.
Second skim pulls in as first skim suction is high. Then you can get 100s of tiny bubbles.
After messing about you will need a orbital sander to try and get a finish. It's as also 4 times the price of plaster.
There is a YouTube video on someone rolling plaster on then skimming which makes it the same as these wall smoothers imo.

What was the problem you had when plaster skimming?

I've always used steamers, out of interest what would be your go to method for wallpaper stripping?

I hear what you're saying about Proroll, and it's something I've already had to take into consideration especially the price, but I would only have used it on that one wall as the others are well within the realms of basic filling and sanding.

My own problems with plastering is just the lack of technique. I know 'how' it's supposed to be done, but I just never developed the muscle memory to get it looking decent. Although this was years ago when I was a tiler/decorator, so it's probably worth trying again with a speed skim maybe. No harm in trying to get a first coat on with Easifill 60 (probably?).

Thanks for the advice, very useful.

Many wallpapers if not all of them now are peelable.
While dry, start at the bottom corner and the trick is to go slowly trying to take off a big peace. This leaves the backing that you wet with a garden sprayer once or twice. Leave 15min and the backing comes off easy.

Other sort won't peel unless you spray with water. Start at the bottom corner and scrape or peel off.

Last sort it wood chip paper or old laura ashley papers. I use a razor sharp wallpaper scraper and dry scrape it off if I can. If that don't work spray with water several times over 45mins. Slow going but will come off if you have a good technique and strength. I guess many DIY people would use a steamer.

If you have to use a steamer spray with water ahead of yourself for 30mins to soften paper to minimise streaming.

People start with a steamer in the centre of the wall without ever trying any water or attempting to peel while it's dry. The steam heat causes severe damage to what should be a good sound wall

Sadly this wallpaper has been there decades.

I used to just wet the walls down back in the 80s, which is probably why I've so steadfastly used steamers ever since lol. The stuff on the walls in this house is well and truly stuck on, but seeing as I have literally the entire house to do still (every bloody wall) there's no harm in going over everything with the perforator and seeing how far I can get with the old methods.

Probably not a bad project to actually learn plastering with after all.....

Yeah I have pretty much the same thing.

I'm definitely going to try traditional plaster in this first room though.

Follow on the trowel on YouTube.

If you're rubbish at it try the sponge surface method then smooth.

Problem is that most PVA don't seal well enough and you get trouble with some spots setting and others staying wet. End result is terrible.
SBR kills suction. Get even drying across area.
When you get confident start using halftime to get the plaster to set.
When you get even better you need a bit of suction to speed things up so maybe start using a bit of PVA then

I already follow him on Youtube, I watch his stuff for fun......

I actually worked with a plasterer for a few years when I was on sites, so I technically know 'how' to do it, but like anything else knowing how to do it and actually being able to do it are two different things.

I need to pick up some bits and pieces tomorrow so I'll get some SBR too.

I appreciate your thoughts on this, pulling me back out of the Dalapro route.
