Want to create crisp, professional-looking lines on your wall? With the right preparation and a few simple techniques, you can achieve clean, sharp edges without paint bleeding under the tape.

✓ Use a long straight board or a level as a guide and lightly sketch your line with a pastel chalk.
✓ Check with the level to make sure your line is perfectly straight.
✓ Apply painter's tape along the line and press it firmly against the wall.
✓ Remove the visible chalk line with a dry or slightly damp cloth.
✓ Seal the edge of the tape with Amsterdam Acrylic Medium Matte 117 for ultra-sharp lines.
✓ Paint the wall using a brush or roller.
✓ Slowly remove the tape while the paint is still wet.
✓ Touch up any small imperfections if needed for a flawless finish.
