American Granby Boss Silicone Adhesive Grout, Neutral Clear, 10.3 oz | 80100

The professional's choice for a permanent, non-corrosive waterproof seal that resists chlorine and prevents leaks in pool and spa environments.  This is the CLEAR color (as opposed to the white 80101B).

Product Overview

The American Granby 80100 (BOSS® 801) is a premium one-part, neutral-cure silicone adhesive designed specifically for the demanding conditions of swimming pools and spas. Unlike acidic acetoxy silicones that release strong vinegar odors and corrode metal components, this advanced oxime formula is non-corrosive, low-odor, and safe for delicate electronics and sensors. It bonds aggressively to diverse aquatic substrates, making it the ideal solution for sealing spa jets, skimmers, and re-adhering ceramic tiles without sagging or washing out.

Key Features

• Neutral Cure Protection: The non-corrosive oxime chemistry is safe for use on metal fittings, lighting fixtures, and sensitive pool electronics.

• Chemical Resistance: Formulated to withstand constant exposure to chlorinated water, salt, bromine, and ozone without deteriorating or discoloring.

• Extreme Adhesion: Bonds powerfully to ceramic, fiberglass, acrylic, PVC, ABS, wood, and masonry, even in vertical or overhead applications.

• Biological Resistance: Contains a mildew-resistant agent to prevent black mold growth and maintain a clean, professional appearance in wet environments.

How to Use

1. Prep: Clean and dry the surface thoroughly, removing all oil, grease, old sealant, and soap film.

2. Apply: Cut the nozzle to a 45° angle and apply the sealant into the joint or behind the tile using a standard caulking gun.

3. Adhere: Press the tile or fitting firmly into place to ensure complete contact with the adhesive.

4. Finish: Tool the sealant bead within 10-15 minutes using a spatula or wooden paddle to create a smooth, watertight seal.

5. Cure: Allow 24 hours for a full cure; the product becomes tack-free in approximately 30 minutes.
