Why has a crack appeared in my wall?
Why do cracks occur on walls?

Tiny nail and screw holes are the easiest to fix. Use a putty knife to fill them with spackling or wall joint compound. Allow the area to dry, then sand lightly. Anything larger must be covered with a bridging material for strength before patching compound can be applied.
Is it normal for plaster walls to crack?
A: Old lath and plaster walls are prone to cracking. Over time the plaster separates from the lath, creating structural cracks. Plaster is also prone to thinner spider-web cracks, which occur when the topcoat of the plaster degrades. It’s common to have both kinds of cracking — and both types can be repaired.
Can you paint over cracks on wall?

What do painters use to fill cracks?
