AG340 100% Silicone Sealant, Clear Caulk for Bath & Kitchen, Waterproof & Flexible

Adhesive Guru AG340 Bath & Kitchen 100% Silicone Sealant is a clear, high-quality sealant designed for long-lasting performance in moisture-prone areas such as bathrooms and kitchens. Made with 100% silicone, this non-paintable formula is ideal where permanent transparency is preferred. It effectively seals gaps and joints around showers, tubs, sinks, backsplashes, countertops, tiles, and more. The high-viscosity, non-drip consistency allows for easy application on both vertical and horizontal surfaces. With excellent flexibility and durability, AG340 resists shrinking, cracking, mold, mildew, and moisture over time. Its acetoxy cure system ensures a fast-curing, strong bond, while the low-odor design makes it suitable for indoor use. A spare cap is included on the nozzle for clean and mess-free storage. Apply easily with a standard caulking gun and achieve a smooth, waterproof finish that stands the test of time-ideal for both professionals and DIY users.

• How to use: 1) Wear protective gloves, clothing, eye protection, and face protection. Ensure the application surfaces are clean and dry. If needed, apply masking tape to protect adjacent areas. 2) Cut off the end of the tube to open it. 3) Trim the nozzle tip to the desired size and attach it to the tube. 4) Insert the tube into a caulking gun. 5) Apply the sealant evenly to the surface. Smooth it with a tool or a gloved finger to fill the application area. 6) After use, reattach the cap on the nozzle to prevent curing. 7) Remove the masking tape. If needed, use clamps to hold surfaces together until the sealant cures. 8) Wipe away any excess sealant with a cloth dampened with solvent before it cures. Once cured, the sealant can only be removed mechanically. Full curing takes 24 hours; avoid direct water exposure before the sealant is fully cured.
• Store in a cool and dry place between 40°F to 75°F, away from direct sunlight and heat sources. Properly seal the container to prevent moisture infiltration. Keep upright to avoid leakage and store in a secure location out of reach of children.
