SUBSTRATE PREPARATION
The substrate must be clean, dry, sound and homogeneous, free from oils, grease, dust and loose or friable particles. Sika® Firerate adheres without primers and/or activators.

APPLICATION METHOD / TOOLS
Sika® Firerate is supplied ready to use. After the necessary substrate preparation, insert a suitable backing rod to the required depth and apply any primer if necessary. Insert a foil pack or cartridge into the sealant gun and extrude Sika® Firerate into the joint making sure that it comes into full contact with the sides of the joint and avoids any air entrapment. Sika® Firerate sealant must be firmly tooled against the joint sides to ensure adequate adhesion. It is recommended to use masking tape where exact joint lines or neat lines are required. Remove the tape within the skin time. Do not use tooling products containing solvents. Water can be used if wet tooling is required.

CLEANING OF TOOLS
Clean all tools and application equipment immediately after use with water. Once cured, residual material can only be removed mechanically

LIMITATIONS
• Sika® Firerate may be overpainted with solvent free paints.
• Do not use Sika® Firerate on damp and/or wet substrates.
• Do not apply Sika Firerate at temperatures below 5ºC
• Do not use Sika® Firerate to seal joints in and around swimming pools.
• Do not use Sika® Firerate to seal joints in external applications on non-porous substrates.
• Do not use Sika® Firerate for joints under water pressure or for permanent water immersion.
• Do not expose uncured Sika® Firerate to rain or water as this may interfere with the curing reaction.
