I bought a gallon of it and it is a two part stuff. Seems pretty good when rolling it on. Taking forever to dry though. The direction said to use all of both parts however I had small areas to do today. The black stuff is 96 ounces and the activator was 14 ounces. If I figured correctly that is a 7:1 ratio for mixing. That is the mixture I used to mix up my small batch. Stuff should have been dry 2 hours ago but not... Any body have any experience with this brand liner?
