Cratering

Cause

Problems of this nature can be caused by rain falling onto the semi dried coating or  aeration/frothing of the paint during application usually by roller and not flowing out properly. Also referred to as pin holes

Solution

Once the coating is completely through dry, flatting down should take place using carborundum (wet or dry) abrasive paper preferably wet – using water/soap  or white spirit as a lubricant. Recoat with chosen paint finish.
