Fix blistered newly skimmed walls with this easy to follow ‘how to’ guide.
Here is one scenario – you paint a new colour onto a wall that has previously been painted and while the paint is still wet you notice it bubbling up! Then, when you rub the bubble it bursts and leaves the original plastered wall showing! Now you have an uneven surface.
It happens when newly plastered/skimmed walls or ceilings aren’t given enough time to completely dry before painting. The temptation is to start painting as soon as the plasterer has left the building but plaster takes longer to completely dry than you might think.
If the plastering has been done in the winter months it will need several weeks to thoroughly dry – please don’t be tempted to wack the heating on full blast to try to speed up the drying process because the sudden rise in temperature can cause different problems.
Another reason it occurs is when the initial coat of paint on the new plaster is bog standard silk applied undiluted directly to the plaster.
