desertcart.co.jp: Lindeman 750103 Flash Seal - Black - 1 Gal : DIY, Tools & Garden

Review: I ordered this product to repair a nagging chimney leak that I could not seem to remedy with roofing caulk. After the 3rd failure to fix the leak I ordered the Chimney Saver. After the first rain I didn’t encounter a single leak. Although time will tell the whole story I am so far impressed with this product. It was easy enough to apply and very easy to clean up. I bought the Flash Seal reinforcement mesh that is recommended with this product which also helped to create a nice thick layer around the bottom of the chimney. I used duct tape to make a clean application line around the base which worked like a champ. I had some left over so I sealed the top part of the chimney where the mortar was starting to crack. This stuff is a little pricey but it does the job. Saving the expense of calling a roofer was well worth it. Update: The Dallas area that I live in just got hit with a terrible storm that produced extremely high winds and copious amounts of rain. I am happy to report that the repair job on my chimney held up beautifully. Not one drop of water made it through. I now have to say that this product is battle tested, tried and true. This storm was one of the worst that I can remember in several decades so I would gladly tack on some more stars if I could.
Review: We had three leaks where our chimney met the roof line. Applied as directed and all three cracks/leaks are sealed. Using the fiberglass mesh tape is the way to go. Really makes the product stronger and I think will last for years. Oh yes, working from top to bottom helps seal everything and it bonded to both flashing and the brick.

## Questions & Answers

**Q: does cloth come with the sealant?**
A: Negative. As of 12/5/2016, there isn't a 'with cloth' option.

**Q: Does the finished seal need to be coated to provide uv protection and extend the life?  if so, what coatings are acceptable?**
A: No, not to my knowledge. My metal flashing rusted out and I had a temporary patch with some other product (applied like caulking), but that failed in a year. Then I tried this product because I knew it was going to be temporary also because my roof was going to be replaced eventually. So, the reinforcement fabric is a must and follow the directions carefully. It held for 4 years until I eventually replaced my roof. I did not apply any sealant or UV protection product over it.

**Q: Has anyone used this around the flashing of a skylight?**
A: No, but if you use the correct detail around the skylight curb, I do not see why it would not work.

**Q: Where can I get a copy of the Material Safety Data Sheet on Flash Seal?**

*by D***C on May 16, 2022*

This stuff worked as advertised. I had a leak on the inside of my chimney that no roofer wanted to touch. So I finally purchased this product(with the fabric tape) and applied it to the base of my chimney around the flashing. It worked great and no more leaks. Worth every penny and easy to use.
