To prevent bleed through and achieve a clean transition line on textured surfaces, it may be necessary to "back paint" or seal the tape:
- After the lighter base color has dried, mark your transition line using the BullnoseBoss. (It is easier to apply a darker color over a lighter one.)
- Place a strip of painter's tape alongside the line you've drawn onto the corner.
Press the tape firmly into place
- Using the same color of paint that is located beneath the tape – paint over the pencil line and against the tape edge. (Voids under the tape created by the uneven texture will be filled in with paint.)
- Once the "filler" paint is no longer tacky, paint over this edge using your second color. Remove the tape before the second color dries.
