Expanding Foam Sealants - Sika Boom®
ONE-COMPONENT, POLYURETHANE FOAM
Sika Boom® is a pre-pressurized, portable, one-component, polyurethane foam system applied in a bead form. Sika Boom® expands and cures slowly to a semi-rigid, closed cell foam upon reaction with moisture, such as ambient humidity. It is designed for easy dispensing through a straw adapter that is included with each can.
- Tack-free in approximately 5 minutes or less, based on moisture/temperature conditions.
- Fully cures within 12 to 24 hours.
- Cured foam can be sanded, painted or covered
- Cured foam is resistant to heat and cold.
- Adheres to most building materials.
- Expands 2 to 3 times its original size.
Usage
- On any clean surface to fill, insulate and seal around gaps, beneath base plates, muds sills, top plate penetrations, corner joints, T-joints, exterior cracks, around utility panels, pipes, duct penetrations, etc.
- For dispensing as a bead for filling cracks, crevices, and to fill smaller cavities.

Application Steps
APPLICATION INSTRUCTIONSFor the application of Sika Boom® all generally accepted rules of building and construction apply.
SUBSTRATE PREPARATIONSubstrate must be clean, firm, free of loose particles and free of dust, grease, mold release agents. Protect surfaces not to be foamed. Shake can before using. For best results in cavities larger than 3 inches in diameter, dampen substrate to supplement atmospheric pressure humidity in affecting consistent cure throughout applied foam.
