Coalescence void: Paint not forming a continuous film when surface temperature is too cold, usually below 50°F.
Coalescence void causes: Painting when the air or surface temperatures are too cold for the paint to form a film. Painting in non-heated areas. Surfaces deeply chilled need a heating period before painting. Surface temperatures must be 50°F or above.
Coalescence void solutions: Avoid painting interior or exterior surfaces when the temperatures are too cold. Late afternoon painting in unheated areas are vulnerable because the temperature will continue to decrease during the night and prevent proper paint film formation.
Primers & interior finishes: Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Select a top quality interior paint in the color and sheen of your choice.
