- Applications
- Compatible Substrates & Surfaces
- Basic Use
Recommended to seal nonporous surfaces around windows, doors, siding, gutters, vents, and more. Also use it for boats, cars, and more on windshields, fittings, and more. Great for use as an adhesive for fastening small accessories, fittings, repairing loose tiles, and more. Adheres to most nonporous surfaces, including clean metal, glass, most types of wood, silicone resin, vulcanized silicone rubber, ceramic, natural and synthetic fiber, painted surfaces, many plastic surfaces, and more.
- Limitations
Not recommended for continuous water immersion, or where abrasion and physical abuse are encountered. Do not apply to porous surfaces, such as masonry, or on building materials that bleed oils or solvents, such as certain impregnated woods and certain partially vulcanized rubber gaskets, tapes or adhesives. Do not use in totally confined spaces, because the sealant needs atmospheric moisture to cure. Do not use in aquariums as the bio agents in the sealant may be toxic in solution. Paint does not adhere well to silicone. Before product application, user should determine suitability of 100% silicone for intended use.
- Installation
- Joints: Maximum joint size recommended is 13mm (½”).
- Surface Preparation: Thoroughly clean and degrease all surfaces. Then rinse all surfaces, except plastic, with acetone. Rubber surfaces should be roughened with sandpaper, then wiped with acetone.
- Joint Backing: Backer rods should be used in joints over 9mm (3/8”). Bond breaker tape should be used in shallower joints to prevent three sided adhesion.
- Weather Considerations: Do not apply to exterior surfaces if rain is expected within 24 hours.
- Service Time: Let dry 24 hours before exposing to water.
- Cleanup: There is no commercial solvent which will dilute uncured silicone, so care must be taken when applying. Wipe excess uncured silicone away carefully with a soft cloth.
