How long to wait before painting spray foam insulation with fire retardant paint?

ntang | Posted in General Questions on

We are general contractors and sub out the spray foam insulation jobs. Some contractors paint the fire retardant on right away and others say they have to wait a day and thus come back to the job later to paint. I’m trying to find out which is actually right. Do you have to wait 24 hours to paint the foam or not?

    Contact your foam manufacturer.

    AJ gave you one answer. I'll give you a different answer: contact the manufacturer of the intumescent coating (the fire-retardant paint).

    Thank you. I will try to find out who the manufacturers are. I'm new to construction and energy efficiency so have a lot to learn : )
