Painting plaster mistake

angelina773

Thank you everyone for your replies :-)

I must admit I didnt realise decorating was such a nightmare.

MissGrace I hope you dont mind me asking further questions, but I have had a problem with paint bubbling. I finished the room with the diluted (I added 20% water) B&Q cheep paint. Painted two coats and then left it for 48 hours. I went to paint it with the Dulux one coat and like you said it is very very thick and hard to roll, but I also had a problem with a small area of the diluted B&Q paint bubling up as I painted over it.

Have I not allowed the diluted B&Q paint to dry for long enough, or have I done something else wrong?

I had a real dilemma regarding what paint to buy, I wouldn't normally buy from B&Q but had £75 of decorating vouchers. I have opened one pot of paint, but would you advice I return the rest and purchase something else. I have had crown before and it took so many coats it drove me mad, but like you say I'd rather it take longer and look good.

If you can think of a brand of paint that B&Q sell that would be good I would be extremely grateful.

Thanks Again, all this help is very much appreciated as I am far from family and doing this all on my own, so finding it all very hard.

I think, but its hard to give a proper opinion as I cannot see the bubbling, but where that bit has bubbled, I dont think its anything to do with the actual paint, as it would have happened in different areas of the wall.

What I think has happened, and its quite common with plasterers,(no offence to plasterers) is that they get a bit carried away slapping the PVA on to the walls prior to plastering, and perhaps your 'bubbled area wall' was finished, and they were doing another wall ajacent to it, and somehow a splash of the PVA has landed on the finished plastered wall.
This happens a lot, and can cause a bit of grief, as it will stand out like a sore thumb.

Did you also use the 'One coat' before you saw my reply?, as applying that straight from the tub can lift existing underneath paint.

If you have tried sanding the bubbled patch down, repainted it and it still bubbles, then this is what I would do.

Is to sand it down again, get some oilbased undercoat, you might have some lying around in the shed, pour a bit out, less than an eggcup amount, as you only want to do the patch.
Add a tiny bit of white spirit, about a quarter of the bottle cap, mix that into the undercoat and stir.
Get a brush, or save yourself dirtying a brush for a little patch, get some kitchen roll, and dab the mixed UC onto the bubbled patch.
Leave it to dry, then touch up using your colour, again you can use kitchen roll, but dont touch up staright from the tub, do this 2-3 times so it will cover the white undercoat.
Dab with the kitchen roll, so it will blend in with like the rolling effect you have already done with your paint roller.:D

But if you havent tried the touching up bit first, then give it a go, and see how you get on.
But again, dont touch up from the tub, thin it down, even if you have to touch up 3- 4 times, as long as its thinnish, and do it with the kitchen roll, and sort of dab/sponge it on, if you use a brush it might show up against the rolling you previously have done.

Let us know how you get on.

Thank you Misgrace, your reply is really helpful.

I thankfully only painted a small amount of the one coat on before I noticed bubbling. I think the plasterers rolled the pva on all walls prior to plastering. I'm not hundred percent sure though. So I think your right regarding the one coat paint removing the paint already on the walls

I am worried I have caused problems, as I have also been stripping wood with a substance called eco solution paint remover. I may have splashed it on the walls in places. Would just washing it offer be ok?

Do you think I should take the one coat back or will it be ok if I dilute it? If you can tell me a paint from B&Q (don't mind what brand) that I could use instead I would really appreciate it.

Thanks angie
