Caulk ?

[Phil_h]

We have painted a newly skimmed wall and where it meets the wood architrave of the door it has tiny paint cracks in the emulsion.
The wall and architrave are at right angles to each other.

Should we have put a tiny bit of Caulk in before we painted.?

Does the same apply to a plaster skimmed upto a new UPVC window.?


Thanks.

Anywhere there is a small gap you can use caulk. It is flexible when it dries and can be painted over. It will move a bit with the expansion and contraction of the wood.
