How to use


Make sure all surfaces are clean, dry, firm and free of frost. Clean all joints to release hydrophobic agents, cement laitance, dust, dirt, old sealants and other contaminants that may impair adhesion. Metal surfaces should be cleaned and degreased by wiping with a suitable solvent using an oil and lint free cloth. For further advice on specific substrate cleaning, please contact Dow Technical Services.
Note: Always ensure adequate ventilation when using any solvent. Avoid heat, sparks and open flames. Follow all precautions listed on the solvent container label or on the Product Safety Data Sheet.
DOWSIL™ FIRESTOP 700(CN) Sealant should not be applied to surfaces below 5°C (41°F) as a dry, frost-free surface cannot be guaranteed at these temperatures.


DOWSIL™ FIRESTOP 700(CN) Sealant has excellent adhesion to most common construction substrates.
Cement or concrete must be primed with DOWSIL™ P Primer for optimum adhesion


Areas adjacent to joints must be masked with tape to prevent contamination of substrates and to ensure a neat sealing line. Masking tape should be removed immediately after processing.
