Blocking

The paint sticks to itself when a window or door is opened and usually leaves bare patches of substrate.
Cause:

Not allowing sufficient dry time for the coating before closing doors or windows.
Use of a semi-gloss or gloss paint with low blocking resistance.
Painting in warm conditions.

Solution:

Use a high quality semi-gloss or gloss latex or oil paint with good blocking resistance.
Follow paint label instructions regarding dry times.
