Application steps

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 AP adheres without primers and/or activators. Pre-dampen the substrate with a mist spray of clean water, this ensures that the foam cures properly and also prevents secondary foam expansion.

CLEANING OF TOOLS

Clean all tools and application equipment immediately with Sika® Boom Cleaner and/or Sika® Remover-208 or equivalent. Once cured, residual material can only be removed mechanically.
