Re: Need Help on expoxy application
All from the same can.
I did not pour it on the floor. Using a paint tray and roller... is that not the way to do it?
That is NOT the best known method. From what I have learned from more experienced people here on the board, unlike paint, epoxy does not "dry." Rather, it is a chemical reaction between the part A and the part B. This chemical reaction creates heat, which in turn causes the chemical reaction to go faster, which creates more heat, etc. Because of this, leaving the mixture in the paint roller tray or in the bucket is not advised.
So, the best known method is after carefully mixing the part A and B together via the instructions (for example, mix with an electric paint mixer at 300 RPM for X minutes without drawing air into the mixture), you immediately pour it out in a ribbon on the slab. The heat generated by the chemical reaction is absorbed by the concrete mass, which in turn also cools the mixture, thereby slowing the reaction down, which gives you more time to work the mixture. However, you have to be careful not to cool it down too much, or the reaction will stall and never complete and you'll have a really disgusting gooey mess on your floor that will not harden. Because of this, you don't want to apply epoxy when it is too cold. From what you describe, you don't need to worry about that right now - it sounds like your conditions are pretty much ideal.
The last trick is DO NOT turn the bucket upside down and let it set on the slab so every last drop of epoxy comes out. If it were paint, that might be a good way to get the last half cup or so out of the bucket. Don't do that with epoxy, because the material that adheres to the bucket may not be thoroughly mixed between part A and part B, and if so, it will not cure correctly on the slab.
I defer to more experienced people, but I hope this helps in the interim.
Good luck!
