Surface Prep:

All surfaces to be coated must be clean, dry, and paintable. It may be necessary to power wash and/or prime to enhance adhesion. See application specification for more details.


This product may be applied directly to any clean, dry surface. Polyurethane foam should be coated within 24 hours of application. Apply by spray, brush, or roller as received. No thinning or reducing is necessary. Subsequent coats should be applied within 24 hours of prior applications to insure full and uniform adhesion.

It is not recommended that this product be applied at temperatures below 50°F. (10°C.), or if rain is expected within 1 hours of application. High Solids Silicone 412 may be applied at lower temperatures. However, cure time will be extended.


Clean spray equipment with Mineral Spirits. Recirculate through lines and gun until residual is removed.


Applied coating will cure in 2 to 8 hours depending on temperature and humidity.
