how do stop paint peeling when wall has been plasterd?

Question

wall has new plaster tryed to paint but keeps peeling any tips how to stop it

Answer 1

New plaster has to dry out for a couple of months, the paint if pealing because moisture is still evaporating from the walls, Adding glue to the paint will only trap the moisture in thus never letting the walls cure. (could of had colored plaster put up) After the plaster has cured, use a primer and then paint.

Answer 2

You should not paint over newly plastered walls until they have thoroughly dried out, this may take a week depending on ventilation and humidity of the room. You could put sizer on the wall to seal it such as unibond which paints on sealing the wall in preparation for painting. I remeber having newly plastered ceilings and painting them. I remeber painting my ceiling which I did not know had a lime wash on it the paint blistered and I had to scrap it off and restart the whole process of washing sizing and painting. Come to think upon it, they all need to be done again that was a few years ago. But I will will do it when I have the time and the inclination. lol

Answer 3

Ok first of all, is the plaster completely dry? It may look and feel dry but might not be "cured" yet. If plaster is dry, try using a primer as a base coat before you put your finish coat on. Try one of the Kiltz line of products, they seem to give the best results and will block any of the acids that might be leaching out the plaster.

Answer 4

Don't use pva glue because you will be sealing in the moisture which takes months to dry in the plaster. The plaster needs to breathe you need to apply a miscoat which is emulsion (10 lirtes ) land 1 third clean water .

Answer 5

Make sure your plaster has cured completely.

Seal the walls with a pva primer and let that dry completely.

Finally paint over.

Answer 6

mix in some pva glue into the paint and give it a first coat to seal the wall then allow to dry the paint as normal

Answer 7

Firstly let the walls dry out completely. Then get some cheap white paint ( the B&Q brand 10L is good ) then apply two coats of that then your choice of colour. It worked for me.

Answer 8

the walls need to be prepared first with a light mixture of PVA glue and water - instructions are on the tin, also allow time for the walls to dry out

Answer 9

you should have used awash coat first that was watered down so to provide a good base for further coats.don't use any vinyl paint as this will hold water in and can bubble up.some times a contractors emulsion is used.
