Surface Preparation: Ensure that surfaces to be sealed are clean, dry, sound and free from grease, dust and other contaminants which could impair adhesion. Surfaces can be cleaned and degreased by wiping with a suitable solvent such as DOWSIL™ R-40 Universal Cleaner on a clean oil and lint-free cloth before application of sealant. Check to ensure that the mirror has been evenly coated, is protected by lacquer and is free of scratches.
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.
For specific advice, please refer to our Primers' Guide or contact our customer care.
The sealant is ready to use. Apply 10 mm wide strips vertically on the back of the mirror in 100 mm intervals. Then press the mirror onto the surface, preserving a constant bead thickness of 2 mm for optimum cure and mechanical grab. Support the mirror for a minimum of 24 hours using adhesive tapes. This will ensure good contact and a minimum of displacement. Air should be allowed to circulate freely around the edges of the mirror thereby allowing the sealant to cure.
Excess sealant may be cleaned off tools and non-porous surfaces whilst in an uncured state using DOWSIL™ R-40 Universal Cleaner. If sealant is misapplied to porous substrates, it should be left until just cured, and then removed by peeling, cutting or other mechanical means. Care should be taken not to damage plastic or coated surfaces.
