Usage

Sika Boom®-115 Flame resistant is designed for filling gaps around pipe entries through fire rated walls. It provides a fire rated seal around window, door frames, timber structures, windowsills and thresholds and electrical wire chasing prior to plastering. It can be used for deep joints prior to applying sealant or plaster. It seals irregular gaps in stone, bricks, concrete or plaster. Sika Boom®-115 Flame resistant can also provide insulation behind cladding to exterior walls, soffits and barge boards.

APPLICATION INSTRUCTIONS

For the application of Sika Boom®-115 Flame resistant 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®-115 Flame resistant 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® Remover-208. Once cured, residual material can only be removed mechanically.
