Get Clean Paint Lines With Tape and a Damp Rag

Everybody tapes before painting, and half the time paint still bleeds under. The tape isn't the problem — the unsealed edge is. A damp rag fixes it.

How to do it

1. Apply painter's tape and press it down firmly along the edge that matters.
2. Run a damp (not wet) rag along that edge to activate the seal.
3. Pro move: paint the edge first with the color that's UNDER the tape. Any bleed is the old color and disappears.
4. Paint your new color, and pull the tape while the paint is still slightly wet, pulling at a 45-degree angle away from the line.

Pulling tape after paint fully dries is how the new paint peels off with it. Timing and that damp rag are the whole game.
