Chimney Flashing Sealer

This stuff seems phenomenal , I applied it [ Colorado ] we have had a very wet 2023 Summer , now it [ October ] seems like a drought again . Go figure ... however after EVERY storm this year [ by the way , I did the flashing on my chimney ] it has been soaked and getting to my cinder block foundation . This is not good . Anyway , after this last heavy rain , I looked , behind fireplace ... perfecto ! This stuff sealed my chimney base , so far so good and it applies very easily . The application is VERY easy , it is water based , dries like oil based , that is seems strong , not lingering wet . By the way , other reviews say the paint brush is shot afterwards , not if you wash it pretty soon after application , it is acrylic , so it washes away . Mine did ... so far so good , we will see next Spring . I think it's a winner Thanks

I expected this to put a thin layer of protection over the metal on the chimney flashing, but it was far thicker and easier to apply than I imagined. It was able to fill in all the little gaps easily, and the finished cured coating seems tough, flexible, and thick enough to withstand the weather. I could not be happier, really.

I thought this product to be on the pricey side but I had a leak around my chimney for a few years and tried just about anything Home Depot had to offer. Not only fixed my leak, It worked on my leaks I had on my metal roof as well.

The only way to properly do a crown coat is to tape off the area because the stuff is like tar and once you put the coat on, there’s no going back and touching up until it fully cures. If you go back and touch it with your paint brush trying to fix spots it’s just going to get worse and worse and worse. Wait until it dries and go back into a second coat. Yes it’s a messy job but it’s a quick cheap fix. Use a wire brush make sure you clean the crown before you apply insure a good seal. The product itself works great. They should be paying me for such a great review, but it’s the truth.

Brilliantly executed and very easy to use, would recommend it for anyone looking to save money by doing it yourself. With the the fiber roll you can’t beat the results.

My only complain is people packing these. Since it is not sealed if you put them on the side in a box it will leak. I received 5 items leaking in the shipping box. The product is very good it fixed the leaks.

With the addition of solar panels on the roof of my early 50's house, my roof pulled away from my chimney. There was a gap in the previous sealant. I filled and covered the gap and haven't had any further leaks in my roof. I would definitely recommend buying and if I have roof leaks anywhere else I will definitely buy it again.

It was already open straight out of the box
