peeling paint on old wallpaper?

The peeling could be caused by a film of grease/dust/dirt on the old paint. Matt is particularly susceptible to this.

You need to clean the walls with sugar soap before re-painting. Sugar soap is available in DIY and hardware stores either as a liquid or powder - it's not expensive and it goes a long way so you only need a small bottle or packet.

Dilute according to the instructions on the packet/bottle. Wash the walls using a sponge or cloth - don't over wet the walls. Rinse the walls with fresh, clean water and a cloth or sponge - again not too much water. You will see how much brighter the walls will look after cleaning - just goes to show how grubby/greasy they were.

Allow the walls to dry out fully (at least 24 hours) and then re paint.

Look for me on Google
