I know I tried all brands and this one by far is the best. Once you glue something it will never come off. So don't every plan on taking it off because it won't. So easy to apply. It seales evening out including water. I love the clear color. The smell is not that bad. Over dried there is no smell. I always use it to keeps the bugs out of my shed. It's a great barrier. Highly recommend. ## 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 | #140 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Industrial Joint Sealants | | Brand | GORILLA | | Brand Name | GORILLA | | Color | Clear | | Customer Reviews | 4.6 out of 5 stars 33,106 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 ![100% Silicone Waterproof Caulk, All‑Purpose Sealant, Mold & Mildew Resistant, Flexible Seal, Clear, 10 oz Cartridge (Pack of 1) - Image 1](https://m.media-amazon.com/images/I/61EbuC1Y6NL.jpg) ![100% Silicone Waterproof Caulk, All‑Purpose Sealant, Mold & Mildew Resistant, Flexible Seal, Clear, 10 oz Cartridge (Pack of 1) - Image 2](https://m.media-amazon.com/images/I/81+ONO+SO-L.jpg) ![100% Silicone Waterproof Caulk, All‑Purpose Sealant, Mold & Mildew Resistant, Flexible Seal, Clear, 10 oz Cartridge (Pack of 1) - Image 3](https://m.media-amazon.com/images/I/71VdyAE3P4L.jpg) ![100% Silicone Waterproof Caulk, All‑Purpose Sealant, Mold & Mildew Resistant, Flexible Seal, Clear, 10 oz Cartridge (Pack of 1) - Image 4](https://m.media-amazon.com/images/I/81DbaD7fbfL.jpg) ![100% Silicone Waterproof Caulk, All‑Purpose Sealant, Mold & Mildew Resistant, Flexible Seal, Clear, 10 oz Cartridge (Pack of 1) - Image 5](https://m.media-amazon.com/images/I/81iLWMbJbmL.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.
