MIXING: Settling may occur in shipping causing a gritty texture that does not stick well. Remix if there is separation in dry mixture. Use when temperatures are between 40°F (4°C) and 100°F (38°C). Mix in a clean container with clean water. Add about 3 parts powder to 1 part water and mix until Foam Coat turns to a smooth paste. A drier mix is stronger. Do not overmix.

APPLYING: If using extruded foam (ie Blueboard or Pinkboard) roughen surface with coarse sandpaper. Fill big cracks and holes by applying pasty mixture with a trowel. You may add more water until mixture is thin enough to apply with a paint brush, although thinning weakens coating. Can be applied with a standard spray hopper. Use thinned mixture to texture large areas. For best strength apply at least 1/4" (6mm) thick. Multiple coats may be applied. Try texturing surface before coating sets.

SET TIME: Use within 30 minutes. Sets up in 1-3 hours. Fogging the surface for 24 hours will increase strength.

FINISHING: Remove dust before painting. This product goes on rough and is not sandable. Finish as the surface is setting up.

CLEAN-UP: Clean tools and brushes with clean soapy water before coating hardens.

WARNING: Avoid prolonged contact with skin. Wear dust, skin and eye protection. Use approved respirator when sanding. In case of eye contact, flush immediately with water, consult a physician. Wash hands with soap and water after use and before eating. Keep out of reach of children.
