This clear silicone waterproof sealant formula is 100% waterproof and ready for fast exposure to water in just 30 minutes, fully curing in 24 hours for long‑lasting, durable performance.

Ideal for home repairs, DIY projects, and professional applications, it delivers a reliable, multipurpose seal for any project. DIRECTIONS: TO OPEN: Cut nozzle at a 45° angle to your desired bead size. Completely puncture the inner foil seal. TO USE: -All surfaces should be clean and clear of dirt, grease, oil, and old sealant. For gaps larger than 1/2", use a backer rod. Best applied above 40°F (5°C). -Insert cartridge into a caulk gun. -Apply caulk, pushing the bead ahead of the nozzle. -Smooth the bead immediately after application, before a skin forms. CLEAN‑UP: Wipe off wet sealant immediately with a dry cloth. Isopropyl alcohol may be used according to solvent manufacturer’s instructions. STORAGE: Store in a cool, dry location with nozzle attached. To re‑use, remove the nozzle and clean out cured sealant from the tip. MOLD & MILDEW RESISTANT: Cured sealant is resistant to mold. Clean regularly with soap and water to prevent growth on top of the sealant. Review: Gorilla 100% Silicone Waterproof Caulk—Reliable Protection and Finish - This is a good, versatile sealant that lives up to the Gorilla brand's reputation for strength and durability. Being 100% silicone, it provides a completely waterproof barrier that remains flexible over time, ensuring it doesn't crack or shrink even with slight movement or temperature changes. The mold and mildew resistance makes it a practical choice for moisture-heavy areas like kitchens or bathrooms, helping to maintain a clean and professional look long after application. It applies smoothly and adheres well to a variety of surfaces, making it a dependable staple for both quick repairs and more involved home improvement projects. Bottom Line: A solid and effective all-purpose caulk. It is easy to work with, provides a long-lasting seal, and offers the reliable performance you need to keep your home projects well-maintained and protected. Review: Dries completely clear and good quality - Works great and dries pretty quickly. Used it indoors and started to skim in about 30 mins. Only bad thing is the strong sour smell when it’s wet and it is a pain to wash off fingers. This is normal for silicone caulk though and a sign it’s 100% silicone which is a sign of quality for waterproofing. Once fully dried to the touch after about 18 hours there was only the faintest sour smell that went away after another 12 hours and it’s fully clear which is great. Good quality for the price. ## Features - Indoor/Outdoor 100% Waterproof Caulk – Durable, long-lasting clear silicone sealant for indoor and outdoor use; ideal for showers, sinks, windows, doors, gutters, and vents - 30-Minute Water-Ready – Fast-curing caulk formula allows water exposure in just 30 minutes, perfect for quick home repairs and DIY projects - MOLD AND MILDEW RESISTANT: Formulated to resist mold and mildew in wet, humid spaces; maintain with regular soap-and-water cleaning for lasting surface protection - Highly Flexible & Durable – Clear caulk meets ASTM C-920, Class 35 standards; won’t shrink, crack, or break down over time - Clean Finish & Long-Lasting Performance – Maintains a professional look without yellowing; formulated for long-term results ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MQW8AEM | | Best Sellers Rank | #263 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #3 in Industrial Joint Sealants | | Brand | GORILLA | | Brand Name | GORILLA | | Color | Clear | | Customer Reviews | 4.6 out of 5 stars 33,445 Reviews | | Full Cure Time | 24 Hours | | Global Trade Identification Number | 00052427805003 | | Included Components | (1) 10oz Cartridges of Clear Silicone Sealant | | Initial Hardening Time | 30 Minutes | | Item Form | Paste | | Item Type Name | Silicone Sealant | | Item Weight | 0.01 Pounds | | Liquid Volume | 10 Fluid Ounces | | Manufacturer | The Gorilla Glue Company | | Material Type | Acid Cure Silicone Sealant | | Maximum Gap Fill | 0.5 Inches | | Model | 108311 | | Number of Items | 1 | | Part Number | 8050002 | | Surface Recommendation | Window | | UPC | 052427805003 | | Unit Count | 10.0 Fluid Ounces | | Warranty Description | Warranty | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** GORILLA - **Color:** Clear - **Full Cure Time:** 24 Hours - **Item Weight:** 0.01 Pounds - **Liquid Volume:** 10 Fluid Ounces ## Images ![Gorilla 100% Silicone Waterproof Caulk, Clear, 10 oz Cartridge | Mold and Mildew Resistant, Flexible All-Purpose Sealant, Fast Curing in 30 Minutes, Indoor & Outdoor Use - Image 1](https://m.media-amazon.com/images/I/61EbuC1Y6NL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: Do you have to use a caulking gun to apply this??** A: Yes. All brands of caulk that come in these 10 oz round tubes need to be applied with a caulking gun, so every handyperson should get one. The cheap ones are pretty much as good as the expensive ones. What a lot of people giving bad reviews don't seem to realize, is that all brands of caulk in these tubes come with a seal membrane inside the nozzel. The caulking guns come with a rod, about the size of a nail, attached. Just fold out that rod and stick it down the nozzel a few times to break that membrane, or you can use a screwdriver or other device of your choosing. **Q: Can I use this product to fix loose outdoor ceramic tiles due to worn grout?** A: Hello, Gorilla Clear 100 % Silicone Sealant works well to seal around tiles surfaces. To reattach the tile, we recommend Gorilla Heavy Duty Construction Adhesive.
