Paint bleeding under tape on an accent wall

Symptoms

• Thin ragged line of the new color bleeding under the tape edge
• Bleed worse on textured walls than smooth ones
• Lines look crisp in some spots and blurry in others

Likely causes

• CommonTape not pressed down firmly enoughGaps under the tape edge let paint wick underneath by capillary action.
• CommonPainting over a wall textureTextured surfaces leave tiny gaps under tape that smooth walls don't have.
• PossibleBase coat not fully cured before tapingTape applied over a still-soft base coat can lift some of it and create gaps.
• PossiblePaint applied too heavily along the tape lineA thick, wet edge is more likely to seep under tape than a thin, controlled one.

What to do

1. Let the base coat dry fully, at least overnight, before applying tape for the second color.
2. Press the tape down firmly with a putty knife or credit card to seal the edge.
3. Seal the tape edge with a thin coat of the base color painted over the tape line before the accent color.
4. Let that seal coat dry, which locks the tape edge so the accent color can't bleed under it.
5. Apply the accent color in thin coats rather than one heavy pass.
6. Remove the tape slowly at a 45-degree angle while the final coat is still slightly wet.
7. Touch up any small bleed spots with a fine brush once fully dry.

Tools and parts

• Painter's tape
• Putty knife or card
• Small artist brush

When to call a pro

Call a painter for complex multi-color designs or very large accent walls where clean lines matter most.
