How to fix blistered newly skimmed walls


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.

Step One

On old plaster doing this – give it a light sanding and apply a thinned coat of matt paint – thinned with water to make it sloppy. Allow to dry thoroughly and then paint as usual.

Step Two

On new plaster – the plaster should be given plenty of time to dry. Don’t rush this process.

Step Three

Once dry, the first coat of paint on the new plaster should be matt (preferably white) and it should be thinned with water so that it is sloppy. Paint all the plaster with this mixture. It is your undercoat. It will sink into the surface of the plaster and give you a sound base for painting.

Step Four

Allow to dry. Won’t take that long because it will soak into the new plaster.

Step Five

Paint on another coat and leave to dry – Overnight.

Step Six

Now, you have prepared the plaster for painting and will avoid bubbling and peeling in the future.

Step Seven

Paint in the colour of your choice.
