How long does it take for expandable foam to dry?
Regarding this, how can I make expanding foam dry faster?
Dampen for Fast Curing Expanding polyurethane foam sealant requires moisture to expand and cure. If you're applying foam to dry wood or other dry surfaces, or working on a day with little humidity, misting the area first will help the foam expand and cure faster.
