Paint problem - bubbling

[Kimi]

Ive just started to renovate my lounge and the previous owner had some horrible wallpaper. After stripping it i found a load of paint bubbles under the paper. I started to wash the wallpaper paste off last night and pretty much instantly it started to bubble up all over the place. If i sand it back and paint it now the moisture in the paint will do the same i assume?

Has anyone had this before? what are my options to fix it? i can only think of either stripping all the paint off the wall or wallpapering back over it? its quite a large wall so it would probably take a week to strip

Heres a couple of pics to show you what i mean



The bubbles start like this


Then you scrape them and they go like this.

Yea i used a steamer, then a warm cloth to get the small bits that were left off. Thats the original paint underneath the wallpaper. The rest of the room is magnolia and i guess they decided to make a feature wall and wallpapered over it.

After i scrape the bubbles the paint starts to flake off and you end up chasing it all over the wall with the paint flaking off. There seems to be a weakness in the paint and im worried if i sand the edge of the parts that have lifted. Put fresh paint, the moisture in the new paint causing new bubbles and start the vicious circle.

This was the wallpaper, maybe i should have just painted over it

Thanks guys. I think im looking at scraping the whole lot off. The last thing i want to to get it ready to paint, slap it on then come home from work and find all the paint on the floor

The whole house has been bodged together from top to bottom so im not surprised the walls weren't sealed. In the grand scheme of things this is only a small problem. The worst bodge ive come across so far was the extra toilet they installed was leaking from the back, what did they do to fix it, repair the leak? nah just put a strawberry punnet plastic box and fill it with tissue paper to catch the drips, oh yea then we'll tile it in so no one can see it the mess was horrendous

How would be best to remove this paint? im thinking wet the whole wall and then attack with a scrapper.

Yea ive got one of those scrappers, ill pick up a new blade for it before i get to work.

If i use some GARDZ, would i first need to prime the walls with a 50/50 wash and then apply GARDZ, or go straight in with it.

Update, decided to wallpaper it

I took a day scraping and the finish just wouldn't be up to my expectations.

So bought this

On a side note, this is the standard to which the previous owners kept the whole house. The amount of masking tape ive found all over the place is ridiculous. This was the best bit tho. lol, whats the thinking behind it? oh ill mask the wall so i dont get paint on it, then just leave the masking tape?. LOL!

heh yea. Its madness!

ha just noticed the paint all over the window frame as well! have to tend to that later!

Wallpaper isnt up yet, im laying the floor at the moment so hopefully ill be able to get that down, the skirting on and the paper up over the weekend.

Put the wallpaper up at the weekend. The paste made the paint bubble in places so hoping it goes down when it dries out. Either way, look better than it did with a hole in the wall

After i removed the fake wood fireplace it turned out to be an old back boiler so rather than fit another ornamental one i decided to just fill it in, gives the room more of a flow now not having to walk around it when you go in.

Indeed, in the future i will be using gardz. Infact im looking at a similar situation with the walls in the kitchen so i will pick up a tub. Quite pleased with how this has come out tho considering.
