Symptoms
- Old wall color visible through the new paint
- Patchy or streaky appearance after drying
- Coverage looks fine wet but uneven once dry
Likely causes
- CommonNot enough coats appliedMost paints need two coats for full, even coverage, especially over a different color.
- CommonPainting a dark or bold color without primerStrong colors, especially reds and dark tones, often need a tinted primer to cover fully.
- PossibleUneven application or rolling techniqueRolling too thin or unevenly leaves visible variation once dry.
- PossibleLow-quality or old paintCheaper paints or paint that's been stored a long time may not cover as well.
What to do
- Let the current coat dry fully before judging coverage, since wet paint looks different than dry.
- Lightly sand any rough spots and wipe away dust.
- Apply a tinted primer if painting a strong color over a lighter one, or vice versa.
- Apply a second full coat once primer or the first coat is dry, using consistent roller pressure.
- Use a quality roller nap suited to your wall texture for even application.
- Check coverage in good lighting from multiple angles.
- Apply a third coat if needed for full, even coverage.
Tools and parts
