リンデマン750103フラッシュシール - ブラック - 1ギャル

Easy to install and creates a great seal.

the product came already hard in packaging and could not use this... was ready to fix roof then had to run and find a different product

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.

This stuff works great!

11/5 stars, this stuff saved me close to 1100 dollars in roofing repair. So, my situation: My house is nearly 150 years old with a steel roof of indeterminable age. Spoiler alert, it leaks. Particularly bad was the flashing around the chimney, which was "sealed" with sheet steel, mortar, and dreams. It leaked like a sieve. In addition to a few other repairs I needed (rusted out roof bolts, seam leaks where roof meets exterior wall, etc), roofers and chimney specialists quoted me between 1100 and 1800 to stop all the leaks. I asked them what products they'd be using, and they all said "FlashSeal and mesh". Being the cheapskate, DIY nerd that I am, I googled it. Any moron can apply this stuff. I cleared the old flashing, pressure-washed the contact areas, and painted the stuff on. Done in less than an hour. So then I looked at my remaining 9/10ths of a bucket of Flash Seal, and got a little crazy. I put down FlashSeal, Mesh, and more FlashSeal anywhere that even *looked* like it *might* be the source of a leak. It's been two weeks, and I have not been able to locate a single continued source of leaks. So far, so good. I will update in a year to see if the stuff has withstood the test of time. For those curious, the installation goes thusly: Clear the contact surfaces thoroughly. I used a pressure washer, windex, and a towel. Apply a generous coat of FlashSeal. Let it get a little sticky. Apply a layer of FlashSeal reinforcement mesh, covering the gaps you're looking to seal. If it's on an angle, start from the bottom and layer the mesh such that the 'higher' part that overlaps is on top. Apply a generous coat of FlashSeal on top of the mesh. Keep applying until the mesh is coated into a single, continuous surface without any holes. Wait 45 minutes, repeat. Keep doing that until you are confident that nothing can get through.
