American Granby Boss Silicone Adhesive Grout, White, 10.3 oz | 80101B

The professional's choice for a permanent, waterproof seal in high-moisture pool and spa environments.

Product Overview

The American Granby 80101B (BOSS® 801) is a one-part, neutral-cure silicone adhesive and grout designed specifically for the rigorous demands of the pool and spa industry. Unlike standard hardware store silicones that release corrosive acetic acid (vinegar smell), this professional formula is non-corrosive and low-odor. It is engineered to adhere ceramic tile to difficult surfaces like fiberglass and acrylic, making it the ideal solution for repairing spa jets, skimmers, and pool fittings without damaging sensitive mechanics or sensors.

Key Features

• Neutral Cure Protection: The non-corrosive oxime formula is safe for use on copper, chrome, brass, and sensitive electronic sensors, preventing the corrosion often caused by standard acidic silicones.

• Extreme Adhesion: Bonds aggressively to ceramic, glass, fiberglass, ABS, PVC, wood, masonry, and acrylic surfaces.

• Waterproof & UV Stable: Designed for total water immersion and long-term exterior use; it will not yellow, crack, or degrade under harsh UV rays or pool chemicals.

• Mildew Resistant: Contains fungicidal properties to resist mold and mildew growth in humid, damp areas.

• Chlorine Resistant: Specifically formulated to withstand the chemical balance of treated pool water.

How to Use

1. Prep: Ensure all surfaces are clean, dry, and free of old sealant, oil, or grease.

2. Apply: Cut the nozzle to your desired bead size (45° angle recommended). Piercing the foil seal, load into a standard caulking gun, and apply a steady bead.

3. Adhere: For tiles, apply to the backing and press firmly into place. For sealing fittings, push the bead ahead of the nozzle to ensure no air gaps remain.

4. Finish: Tool the joint within 5–10 minutes using a spatula or gloved finger to smooth the seal.

5. Cure: Allow to cure for at least 24 hours before filling the pool or spa (cure time depends on temperature and humidity).
