Can West System Gardner's be mixed?

2 posts in this topic

Hi, I am building the FS 14 from Bateau. I'm currently using the West System standard epoxy resin and the slow hardner. I'm almost to the end of a can of the slow hardner and I am very frugal with my materials. That said, I am betting that I am going to run out of the hardner but I have a fresh can of fast hardner ready to go. Will the world come to an end if I mix a batch using the correct ratio of hardner and resin but mix the slow and fast in the batch?

The important part is to use a 5 to 1 ratio of Resin to Hardener.  It doesn't matter which hardener you use.  You can even mix the fast and the slow hardener together to get a medium cure rate so long as the resin and hardener ratio is 5 parts resin to 1 part hardener.
