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.

Application steps

APPLICATION INSTRUCTIONS

For the application of Sika Boom® all generally accepted rules of building and construction apply.

SUBSTRATE PREPARATION

Substrate 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.
