Painting in high-humidity environments can create multiple
issues, including increasing drying time by introducing more
moisture into the paint
Humid conditions also hurt the adhesion of paint to wood
surfaces because the moisture can be absorbed into the
wood causing bubbling or peeling.
In some cases humidity can cause surfactant leaching, which
results in a white or brown discoloration on the paint’s surface.
When high humidity is combined with low temperatures,
condensation can occur on the naint’s surface which creates
more difficulties in terms of the paint’s drying and adhesion,
compromising its protective qualities.
