The secret to perfectly crisp paint lines

Tired of paint bleeding under the tape?

You carefully measure your design, apply painter's tape, and start painting. Then comes the disappointing moment: you remove the tape and discover uneven edges or paint that has seeped underneath.

Fortunately, there's a simple professional trick that makes a huge difference. Before painting your new color, seal the tape edge with the wall's existing color. Any tiny gaps beneath the tape will be filled by the original wall color first, preventing your new paint from bleeding underneath. The result is a sharp, clean line with a professional finish.

This simple technique is one of the easiest ways to improve the quality of your wall designs and achieve crisp edges every time.
