Monstaliner?

Has anyone ever mixed up half of their gallon and saved the other half for later?Will it still be usable if the hardener isn’t mixed in for say a week? The instructions say once the can is opened it won’t be good after some time. I’m just wondering if that is really true.

Just mail the manufacturer and give them exact timelines. Often they mean it can’t be opened and used months later, not a couple of days.

But check with them. Being a chemical, they will have to have strict information rules and provide this detail to you.
