How to Use:

• Safety Precautions: Ensure good ventilation at the work station. Wear personal protective equipment. Do not eat, drink, or smoke when using this product. Always wash hands after handling.
• Surface Preparation: Ensure substrates are clean, dry, and free from dust, grease, rust, and contaminants. Clean non-porous surfaces (like aluminum and glass) with solvent and dry thoroughly. Mechanically clean porous substrates (like concrete and brickwork) with compressed air, sandpaper, or a hard brush. Mask off joint edges with self-adhesive tape for protection.
• Application: Use polyethylene bond breaker tape or backer rod to adjust joint depth and avoid three-sided adhesion. Cut the nozzle to the desired bead size. Apply the sealant as evenly as possible using a professional caulking gun. Tool the joint surface with a smoothing tool to ensure full contact with the sides and backup material before skin formation.
• Finishing: Remove masking tapes immediately after smoothing the sealant. Allow the sealant to cure fully.
• Cleaning: Uncured product can be easily removed with a damp sponge. Cured product must be removed mechanically.
