Tube, Clear, 1 Pack From the Manufacturer Long-lasting formula gives tight, weather-resistant seals to glass, metal and ceramic surfaces. Will not crack, shrink or peel. Can be applied at temperature below freezing. 50 year limited warranty. Interior/exterior use. Solvent clean-up. Review: Good product - Worked perfect to seal the toilet to floor gap. Review: Nice Color - REVIEW FOR BRONZE COLOR. It took me a bit to figure this sealant out as I was not use to the viscosity of this silicone once I started applying it. It's not as firm as most silicone I've used in the past. I imagine that is for self leveling. However, once I became acclimated, it worked great and the color was spot on for the oil rubbed bronze fixtures I was sealing around. I would use this product again. ## Features - Package Dimensions: 2.794 L x 19.431 H x 5.334 W (centimeters) - Included components: Painting Supplies;Abrasives & Surface Preparation;adhesive-caulk - Solvent clean-up - Manufacturer: Red Devil ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00009V3ZG | | Best Sellers Rank | #10,358 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #30 in Silicone Adhesives | | Brand | Red Devil | | Brand Name | Red Devil | | Color | Clear | | Customer Reviews | 4.5 out of 5 stars 1,918 Reviews | | Full Cure Time | 24 Hours | | Global Trade Identification Number | 00075339008201 | | Included Components | 1 | | Item Form | Liquid | | Item Type Name | 100% Silicone Sealant Architectural Grade | | Item Weight | 0.01 Ounces | | Liquid Volume | 2.8 Fluid Ounces | | Manufacturer | Red Devil | | Material Type | Silicone | | Model | 0820 | | Number of Items | 1 | | Part Number | 0820 | | Surface Recommendation | Door,Siding | | UPC | 787461636428 075339008201 | | Unit Count | 83 Milliliters | | Warranty Description | Manufacturer | | Water Resistance Level | Water Resistant | ## Product Details - **Color:** Clear - **Brand:** Red Devil - **Item Weight:** 0.01 Ounces - **Liquid Volume:** 2.8 Fluid Ounces - **Full Cure Time:** 24 Hours ## Images ![Red Devil 0820 100% Silicone Sealant Architectural Grade, 2.8 oz.

It took me a bit to figure this sealant out as I was not use to the viscosity of this silicone once I started applying it. It's not as firm as most silicone I've used in the past. I imagine that is for self leveling. However, once I became acclimated, it worked great and the color was spot on for the oil rubbed bronze fixtures I was sealing around. I would use this product again. ### ⭐⭐⭐⭐ Color may not be same as swatch or description *by J***. on March 26, 2026* Appears to be a good quality product. Only word of caution, and reason I gave 4 stars instead of 5, is because of color. I selected Gray, but once I opened, it is closer to silver. be cautious of color descriptions. ## Frequently Bought Together - Red Devil 0820 100% Silicone Architectural Grade RTV Sealant, A Water-Resistant Adhesive for Interior and Exterior Use, 2.8 oz.
