APPLICATION INSTRUCTIONS
For the application of Sika Boom® FR all generally accepted rules of building and construction apply.
SUBSTRATE PREPARATION
The substrate must be clean, sound and homogeneous, free from oils, grease, dust and loose or friable particles. Paint, cement laitance and other poorly adhering contaminants must be removed. Sika Boom® FR adheres without primers and/or activators.
Pre-dampen the substrate with clean water, this ensures that the foam cures properly and also prevents secondary foam expansion.
CLEANING OF EQUIPMENT
Clean all tools and application equipment immediately with Sika Boom®-Cleaner and/or Sika® Remover-208. Once cured, residual material can only be removed mechanically.
