Blocking

Possible cause

Blocking happens when a sufficient drying time has not been allowed before closing doors or windows and is more common when using low-quality semi-gloss or gloss paints.

Solution

Use a premium semi-gloss or gloss acrylic enamel paint like Dulux Aquanamel®. Low quality semi gloss and gloss water-based paints can have poor block resistance, especially in warm, damp conditions. Always follow paint label instructions and dry times. Acrylic enamel paints have a better early block resistance than vinyl latex paints.
