How can I pour resin/epoxy over sand?
The catalyst is like an activator with the resins I've used. Once resin is dry, it is heat resistent to a point and once the temperature rises above that it will melt. For example, I have cast resin statuary in the garden which experiences temperatures over 100 degrees where I live and it doesn't melt. But, resin definitely melted when the wild fires roared through here last year because it was subjected to direct heat and flame.
its not a donation, its a fee, my dad is the groundsman of a football club and when it was really hot and the grass on the pitch started to burn, they got the fire dept to water the pitch but it cost them a pretty penny, I'm not sure how much though!
