It's another one of these products with a scary safety sheet. I had to use it in a confined space so to avoid the fumes I used my vacuum cleaner as an extractor. I didn't notice any fumes. I wore latex gloves to prevent skin contact. The product itself is a sticky goo like Sikaflex or Silicone. It hardened to a firm rubbery mass in 24 hours, even though it was 10 - 20 mm thick in places. I was using it as a cement and sealer. It has cemented well but there are some fistulae that leak and will need a second application. I was expecting this, and have reserved some of the product. I am using lollipop sticks or little ice cream spades to work it into the desired shape. Very sticky, so not the prettiest of results, but I am satisfied with it!
