Applying thermal paint (i.e. DC315 and TPR2) seems straight forward, but it can be anything but straightforward if not paying attention to the conditions at hand. Uncured intumescent paint can be an annoying source of odor call backs.
To avoid these problems follow a few simple guidelines:
The surface of the foam you are trying to paint has to be 5 degrees above the dew point. This being 5 degrees above the temperature when condensation would occur. If the foam is too cold and there is a lot of humidity in the air, then there might be too much moisture on the surface of the foam and the paint will not adhere well.
The surface must be adequately dry, otherwise it will not cure properly and it may delaminate over time; particularly when exposed to cold-temperatures - the paint can liquefy again.
The paint must be completely dry before being exposed to cold-temperatures - this is EXTREMELY important in cold storage and other similar applications. Use fans to dry the paint completely and ensure it is 100% tack-free before cooling the ambient air. It is advised in existing attics to leave a fan running for 24-48 hours to ensure it is completely dry.
By following these basic steps you can avoid irritating callbacks and unhappy customer.
