DOWSIL 786 Silicone Sealant is designed to seal nonporous surfaces around showers, tubs, sinks and plumbing fixtures where conditions of high humidity and temperature extremes exist.

Typical applications include:
• Sealing around shower-tub enclosures, tubs, sinks, urinals and whirlpools
• Sealing around bathroom fixtures
• Waterproofing rimless sinks
• Ceramic tile grouting

 

APPLICATION

Surface Preparation

Ensure that surfaces to be sealed are clean, dry, sound and grease-free. Clean with DOWSIL R40 Universal Cleaner or methylated spirits depending on the substrates to be sealed, and dry thoroughly with a clean, lint-free cloth before application of sealant.

Note: When using any solvent, always provide adequate ventilation. Avoid heat, sparks and open flames. Observe and follow all precautions listed on the solvent container label. Above all, it is recommended that DOWSIL 786 is not applied to surfaces that are below 5°C.

Masking

Areas adjacent to the joints should be masked with tape to prevent contamination of the substrates and to ensure a neat sealant line. After that, masking tape should be removed immediately after tooling.

Priming

Primer is not required on most common nonporous substrates, including vitreous enamel, ceramics, porcelain, glazed tiles, etc. However, for some metals and plastics, priming is required. For more information, please refer to the technical data sheet attached or contact Dow Corning.

Back-Up Materials

Where back-up material is required closed cell polyethene backer rod is recommended. Low tack polyethene tape should be used in joints too shallow to allow the use of the backer rod.

Finishing

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.

Clean-Up

The excess sealant may be cleaned off tools and non-porous surfaces while in an uncured state using DOWSIL R40 Universal Cleaner. The cured sealant may be removed with the aid of
DOWSIL Silicone Sealant Remover, abrasion or other mechanical means. However, care should be taken not to damage plastic surfaces.

LIMITATIONS

DOWSIL 786 Silicone Sealant is not recommended for use in applications involving:

• Structural silicone glazing
• Floor joints where physical abuse or abrasion is likely to be encountered
• Prolonged water immersion
• Cementous surfaces, such as masonry
• Building materials that might bleed oils or solvents – materials such as impregnated
wood, partially vulcanized rubber gaskets or tapes or adhesives
• Totally confined spaces, because the sealant requires atmospheric moisture for cure
• Surfaces sensitive to corrosion by acetic acid vapors (a byproduct of sealant cure)
• A surface that is intended to be painted
