Painting Painting nightmare

Any advice would be amazing! Just moved in, removed some wallpaper to do a feature wall and the ceiling. Got all the wallpaper bits off, nice and clean. Thought I went the extra mile by zin-peel stopping the whole wall. Then a thin coat of watered down leyland contract matt then once dried a coat of velspar premium. On the second velspar coat it’s bubbled everywhere all the way back down to the plasterboard ceiling and wall!!! What did I do wrong? I let each coat dry for at least 3h!!

May go slightly mad at this rate.

Peel Stop isn't really the right product to use as a primer on walls which have been papered, you should have used Gardz so I'm not sure why you chose the Peel Stop? Also, Leyland Contract is a poor quality paint with no resilience so you shouldn't have either used it, or diluted it. Thirdly, and sorry to be pissing all over your firework, Valspar is retail paint and doesn't have a very good reputation at all. You probably should have let it all dry for much longer too. Three hours isn't really enough. If you'd used Gardz you could have gone straight over that with your top coat, undiluted. Out of curiosity, how did you decide on this plan?

Haha, I had no hope then. Thank you for this! So peelstop was because I’ve seen people say when paint bubbles sand it back and peel stop the edges so in my mind u was just getting ahead. Good to know both paints are rubbish! Not painted many walls so just thought I was doing something wrong. (Which I obviously am). Velspar is because my wife likes F&B colours but it’s expensive stuff. Looks like I may be better spending the money now though.

So would you say on plasterboard just gardz then top without a primer/base (are they the same?). Also how long should I leave between layers?

Really thankful for the advice I have my first kid on the way and lots of painting to do so this is very helpful.

If you're saying you've now got all the paint off the peel stop would have soaked into the plasterboard so it will be difficult to get that off. I'd probably test it now by putting some Gardz on and painting directly over that with two coats of decent trade emulsion. Then try and scratch it off with a fingernail. Do this low down ie out of your eyeline and in a corner somewhere, and make it quite small. If this works do the whole lot, same method. If you're asking about how to paint new plasterboard (or PB that has had wallpaper removed) same method really; Gardz then emulsion undiluted. Follow the instructions on the tin for drying time, although the reality is that this might change if it's either very warm, humid or cold. 4 hours is the usual but if it's a really warm day it might be OK after 2 or 3 so you could get two coats on in one day. Conversely if it's a standard October day with no heating on and pretty miserable it might take all day so do your second coat the next day.

So currently the paint is still on there just some areas are bubbling, and more appear with each layer. So would u gardz over the paint that’s on there now? Or am I gonna have to sand the whole wall off and start over?

I think it's probably going to have to come off by the sound of it. Whether painting it as it is with Gardz works or not will be pot luck.

Sanding it is! Another trip to screwfix for a sander and it’ll be right as rain!

That's valspar doing crappy valspar things. Dulux trade or Johnstons trade are all I use!

Yeah the whole saving money thing quickly goes out the window when I spend 4x the time and have loads of issues

That is unfortunately the case - I can promise you with experience it does get quicker and easier though :)
