Dowsil 813C Construction And Concrete Silicon Sealant

Good unprimed adhesion to a variety of substrates
Conforms to ISO 11600-F-25LM
Meets the requirements of EN 15651-4 and EN 14188-2 Class A
Excellent weather ability –virtually unaffected by sunlight, rain, snow, ozone, and extreme temperatures of -40°C to 149°C

Ensure that the surfaces to be sealed are clean, dry, sound, and grease-free.
Clean non-porous surfaced with DOWSIL™ R-40 Universal Cleaner, and dry thoroughly with a clean, lint-free cloth before application of sealant.
Porous substrates such as concrete, brickwork, mortar, etc.
must be mechanically cleaned of loose particles using a steel brush, sanding disc, or any similar means.
When using any solvent, always provide adequate ventilation. Avoid heat, sparks,s, and open flames. Use solvent-resistant gloves.
Observe and follow all precautions listed on the solvent container label.
Areas adjacent to the joints should be masked with tape to prevent contamination of the substrates and to ensure a neat sealant line.
Masking tape should be removed immediately after tooling
Primers are not usually required but might be needed for some specific substrates for maximum adherence.
Where backup material is required, a closed-cell polyethylene backer rod is recommended.
Back-up materials provide back pressure and avoid three-sided adhesion that limits sealant movement capability.
