Questions & Answers

Are you going to put a mesh down first? And how thick is that mesh?

The mesh is optional, if you want it. As a result of not using it, I have a excellent bond with no leaks at all. The product I received was of excellent quality.

Do you know if it works over silicone caulk?

Although I am not familiar with roof sealing, I am willing to learn. In my opinion, I'd definitely scrape away as much caulk and other materials as possible (to avoid future issues with materials breaking down). As an ash-sealing product, I used this on my chimney. that it has retained its playability and, after heavy ground freezing in the fall and rapid thawing in the spring, allows movement of the surfaces to remain sealed. There is actually movement in my house! The climate in which I live varies from one season to another. If you use this product, there would be no need to use silicone or caulking. It is important to keep in mind that the more old material that is removed (silicone/caulking), the longer the job will last! Would you like to ensure that a leak does not occur during the Winter? It is very important to read the curing Temperatures must be maintained at a minimum and at a maximum during application and cure time. This is a process of drying. Normally I advise people to do a half-hearted job of scraping off their old materials (Caulking/Silicone) just to do it correctly. So I would urge you to take your time and do it right!

Is this a 14 square foot or 14 linear foot coverage?

There are 14 square feet in the container, and I believe I could cover that much space. The amount you apply will really depend on how thick you make Approximately 4' by 1' was the size of the chimney that I flashed. My regret is that I didn't buy two 1/2 gallon containers to go with the 5' container.

Do you need to lay mesh or reinforcing tape on the floor?

There's no need for you to do that. There was leaking flashing on the roof, and this overtopped it and sealed the leak thoroughly.

It has a great feature to solve or prevent chimney flashing leaks
5/5

love this product! I like to maintain the flashing around my masonry chimney, and I've always done it with a dab of some product here or there, but if it's small, it is easy to miss an area where there might be a gap. The fire place flooded with water after an 11" rain storm here in WI last year, and a small amount of water did leak With this product, you "paint" it over the flashing and where it meets the roof, then over the brick and the bricks, so no areas are missed - and it's water repellent and fade resistant. A coating has been applied to the whole thing. I found the product to be quite easy to apply Even though this paint is relatively thick, it was easy to apply and brush out with a regular paintbrush. As indicated in the directions, I taped the roof and brick with duct tape and then applied the product. After the tape has been removed, you have an amazing looking project! In the online world, there are a lot of things happening The coverage is listed at line 14 of the instructions This is 18 square feet at a thickness of 1/8 inch. In the Amazon listing, it is listed as 12 square feet, but the product is only half gallon. Therefore, it does not add up. I did 10 square feet with about half of the If I had applied it thick enough, it would have been about 1/16". In order to apply it precisely, it is extremely difficult to get the exact thickness.

The site is easy to use, the price is reasonable, the quality seems high
5/5

This product and the 1 gallon brushable chimney crown repair as well as the 1 gallon masonry water repellent were used to repair a large 4 ft tall furnace chimney constructed in 1970 that was starting to exhibit some spalling on the brick work from years of leaks. I applied two coats of each product and ensured that I had enough coverage for the whole chimney. Although there has been heavy rain, no problems have been noticed. It will be used as needed in the future, but it should last a long time. The flashing products left over can be used on some skylights in the near future. Following the instructions will ensure that you won't make a mistake.

They are helpful, but aren't guaranteed to work for everyone
3/5

It's a tricky one. I've tried it and it We found that it had bonded badly to the metal flashing where it failed (through other factors being too far gone) when we came in to remove it. It goes on easily and forms a rubbery barrier that sticks to masonry and metal. In my experience, it sticks extremely well to asphalt shingles, stone, but ironically it does not adhere well to metal. This indicates that it might fail more in situations with older flashing, which, unfortunately, might be why you are using this brand at all. You're probably just delaying replacing the flashing that's been installed poorly, or that has rusted through. It doesn't work, but it might help temporarily avoid having to replace the flashing that is damaged. In situations to do so, the material may need to be used where the edges of the masonry have loosened or It would be useful to add fiberglass mesh tape to these edges so that they are sealed together well. In a strange way, I think I secretly wanted it to act like the caulk on a wet asphalt patch, to become one with the shingles themselves. In other words, it is not that at all. I removed some of the dried layers of thick acrylic paint, and now that I've removed some that had thoroughly dried, there's some possibility that the corrosion itself will eventually strip down the entire.

Doing it myself saved me a lot of money You can do it very easily! We hired a chimney sweep to do an inspection of our fireplace
5/5

One use recommended was around the fireplace in the form of flashing sealant. Simply for flashing sealant, it was estimated that they would charge $300. Doing it myself was really easy and I ended up saving a great deal of money. Use of the metric system is also included.

I love it
5/5

This product has been used so far around the flashings of two chimneys, but I need to do one more flashing around the second chimney because it runs past a I like the way that this applies really good, and that it is thick so it covers really Having a look at the texture of the product, I get a sense of deamplifiers used in car audio applications, which I find interesting. Following the directions, it does a very good job of covering in just two applications. I will see how the roof holds up in a few days as it's planning to rain hard in a day. I have no reason to believe the roof will have any problems. There's a lot to like about it and it seems to be of.

It's best to apply it between 65 and 80 degrees and when it's going to be dry for a while
5/5

Stir it nicely! You can put it on think and it works just fine. We've solved all of our issues and we've safely made it through a few heavy rainstorms now, so I know it's working. On top of that, we put on crown coat as well as a Siloxane water based There is now no more water in the reservoir!.

The flash seal app is not nearly as useful
3/5

The product was purchased after I ran out of 'flash seal', which I had used in my previous purchase. Because it was a 1/2 gallon container and the area I needed to cover was relatively small, this product was purchased. The grip on this product is inadequate compared to FlashSeal. It is too thin, harder to apply and doesn't retain as much pressure as FlashSeal. If only I had purchased another gallon of FlashSeal (which I did), I could have completed the project right away.

Flimsy handle fell from bucket of goop after it was fully filled (opened)
3/5

As a result, the bucket fell onto the roof and splattered all over. I would simply redo the flashing at that point, but if you have the time set up a huge elaborate roof staging and create a nice level working platform for you to work from then go for it (but I would add another layer of roofing shingles if time allows). I wouldn't recommend this product if you intend to manage the tape, the brush, and the bucket of material while trying not to fall off the roof.
