Is it common for new plaster to crack?
I recently had my wole house skimmed (re-palsterd?) this was done then then walls primed and painted. Now that the walls have been painted i have noticed lots of hairline cracks everywhere! My husband has gone over them with polyfilla and we repainted.
Why is my new plastering cracking?
A: Cracks in new plaster are most commonly caused by shrinkage. This is due to factors that have forced the plaster to dry too quickly. If you switched on your central heating while your plaster was drying, or the weather is extremely hot, plaster can dry out too rapidly and crack.
