Hi guys, this one is for unifinish users. I have a hall stairs and landing todo that has old victorian varnished wallpaper, thats impossible to remove, its stuck solid. I was going to apply blue grit to it because i find pva just beads and never goes tacky on it, but jewsons are doing unifinsh at 7.99 just now, so I'd save a bit on material and also save a day if I wasn't having to apply the grit. But im not sure if unifinsish would be ok going over that type of background. Just wondering if anyone has used unifinish over that type of background before ?

I don't know what Victorian varnished wallpaper is but if this a serious question ..no skim finish should be applied over wallpaper mate.
 
what other options to get it off? score it and then steamer?

the best way to remove lining paper is to skim it and then scrape it up :D

I wouldnt put my name to it though seeing as its a customers house
 
It would stick to it ..but would pull the paper away from surface after not to long like any other plaster with a pva before .

Surely a proper good steamer and scraper will get the paper off
 
Theres no way the paper will come off, its sealed with a varnish, the dampness of the plaster would never penetrate into the paper. Same with a steamer
 
If its the same stuff im thinking of?its as thin as paint,impossible to shift without really damaging the plaster underneath.
A steamer does nowt.
Grit and skim never had a problem...but I think uni would work on it.

Yeah thats the stuff. Gritting it was always the plan, but thought with the offer on unifinish it would be a good job to for it.

I would never skim over normal paper, I think you have to see this stuff to understand what its like. I've no concerns about the paper coming off, I just wasn't sure if unifinish would work on it with it being a varnish rather than a paint.

That's why I don't want to say do it ...but I would be tempted to see what happened if it was my job I would...just don't want @PlasterCraftDundee to blame me if it went tits up.
It does stick to tile adhesive without any pva if that helps.

Haha I wouldnt blame you, I'm thinking of just doing a small wall thats just an area above a door and the two sides, probably not even 1m2. see how that goes before tackling the rest
 
Is it like the black paint on corner near this window?

Hope u do...think u will like it ..I done that ex council house hallway in it this week straight in mix up done.

Even if u just do at least one mix with it @zombie ..for the sake of having a go.
If u think it's shite after using it , just say it...
 
I know the paper your talking about mate, a lot of the old buildings in Glasgow have it. Yes unifinish would be OK. This paper cannot be removed unless you went back to brick or lath.

Cheers Stuart, I knew someone would've come across it before. I'm going to see the customer today so i'll take a few photos to show everyone, hopefully have a few after photos of next week of some nicely bonded unifinish to it!
 
Here's a few photos of the background. Not the best but gives you an idea

@PlasterCraftDundee I did a job the other day that sounds the same, Was told it had been shellacked. The decorator said he tried for about 5 days to get it off, it didn't budge. We used finish (pva'd first) and a tiny bit bubbled but went in a treat, bit greasy towards the end of the sets but that's it. No problems at all. I wish we did use unifinish on it though, save pva-ing the day before
 
I would go with the pre grit then you can check the background the next day then make a better decision. I wouldn't use PVA I think the water out of the finish passes through the background which is what you don't want. The pregrit also provides a mechanical key which will give you a better chance of it staying on.
