Do you remove painters tape when the paint is completely dry or semi

I do when still damp.

Try using a hair dryer on a very low setting. This should loosen the adhesive up.

I also do when damp/just completed the paint job.

Pull it when your ready, just pull in away from the paint ( perpendicular)

Semi-dry.

Just almost dry so that the paint will have a soft, even edge. 😇
