Conforms to SNJF Façade.
DIN 18540 Class F.
Ensure that surfaces to be sealed are clean, dry, sound and grease-free. Clean non-porous surfaced with
DOWSILTM R40 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.
Note: When using any solvent, always provide adequate ventilation. Avoid heat, sparks and open flames. Use solvent resistant gloves. Observe and follow all precautions listed on 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. For specific advice, please contact your local Technical Services.
Where back-up material is required, closed cell polyethylene backer rod is recommended. Back-up materials provide back pressure and avoid three sided adhesion that limits sealant movement capability.
The joint should be tooled within 5 minutes of application to ensure good contact between the sealant and the substrate. Tooling of the sealant also gives a smooth, professional finish.
Excess sealant may be cleaned off tools and non-porous surfaces whilst in an uncured state using DOWSILTM R40 Universal Cleaner. If sealant is misapplied to porous substrates, it should be left until it is just cured and then removed by peeling, cutting or other mechanical means. Care should be taken not to damage plastic or coated surfaces.
The sealant joint width should be designed to accommodate the movement capability of the sealant. When designing joints using DOWSILTM 813C Silicone Sealant, the minimum width should be 6mm.
For joints between 6-12mm wide, a seal depth of 6mm is required.
For joints above 12mm wide, a width to depth ratio of 2:1 should be used.
In situations where fillet joints are needed, a minimum of 6mm sealant bite to each substrate is recommended. For joint dimensions with a width greater than 25mm or a depth greater than 15mm, please contact your local Technical Services.
