Close up image of the result when two painted surfaces are pressed together, one of the surface looks like the paint is peeling.

Blocking

Undesirable sticking together of two painted surfaces when pressed together (e.g., a door sticking to the jamb).

Causes

  • Not allowing sufficient dry time for the coating before closing doors or windows.
  • Use of low-quality semi-gloss or gloss paints.
  • Applying another coat of paint before the previous coat is completely dry. Applying excessive amounts of paint on a surface.

Solutions

  • Use top quality semi-gloss or gloss paint. Low-quality latex paints can have poor block resistance, especially in warm, damp conditions. Acrylic latex paints generally have better early block resistance than vinyl acrylic paints, or alkyd and oil-based paints. However, alkyd and oil-based paints can develop superior block resistance on further drying/curing.
  • Follow paint label instructions regarding dry times.
