Hybrid is not water clean-up. - I certainly have used caulk guns many times, but I was working in a tight space. This made it easy! If your space is even tighter, you might buy the 3-ounce tube, but it is very expensive per ounce. I got the 9-ounce tube of the hybrid polymer. Which is still expensive per ounce compared to standard tubes. But the easy trigger makes it worth the money, especially when working in difficult places. There are advantages and disadvantages between silicone and polymer. For my application, polymer is much superior. But polymer is NOT water cleanup. That is not the product's fault, it is the nature of polymer sealant. You just need to know that. I did use my finger with it, and it isn't easy to get off but that is something I understood. I guess the only complaint I have with the spray can is that you can't tell how much you have left of the product. You just use it until it runs out. But the 9-ounce tube completed my project. One user complained that it was difficult to control the size of the bead even with the adjuster. I didn't have that problem, it came out great for me. ## Features - So easy to use. - No caulk gun needed. - Adjustable Trigger Flow Nozzle. - Advanced hybrid polymer formulation. - Snap & Save cap eliminates waste. - Seals out water, air, and moisture. - Adheres to virtually any surface, wet or dry. - Won’t shrink, crack, or become brittle. - UV and chemical resistant. - Fully paintable. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D2F2DCXM | | Best Sellers Rank | #136 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Adhesive Caulk | | Brand | Flex Seal | | Brand Name | Flex Seal | | Color | White | | Customer Reviews | 4.3 out of 5 stars 2,040 Reviews | | Full Cure Time | 24 hours | | Global Trade Identification Number | 00810129870756 | | Included Components | Flex Caulk, White, 9 oz, 1-Pack | | Item Form | Liquid | | Item Highlight | No caulk gun needed, trigger flow nozzle, paintable, won't shrink or crack, seals wet or dry, bath, kitchen, sink, window, RV | | Item Weight | 255 g | | Liquid Volume | 9 fluid ounces | | Manufacturer | Swift Response, LLC | | Material Type | Hybrid Polymer | | Model | CFSWHTR675 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | CFSWHTR675 | | Surface Recommendation | Window | | UPC | 810129870756 | | Unit Count | 9 Fluid Ounces | | Water Resistance Level | Waterproof | ## Product Details - **Brand:** Flex Seal - **Color:** White - **Full Cure Time:** 24 hours - **Item Weight:** 255 g - **Liquid Volume:** 9 fluid ounces ## Images ![Flex Caulk Hybrid Polymer Waterproof Sealant, White, 9 oz, 1-Pack - Image 1](https://m.media-amazon.com/images/I/51bs-g2NBfL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It's good stuff *by H***R on September 7, 2026* Works just like they said it would ### ⭐⭐⭐⭐⭐ Great in tight spaces.
