The difference with the Cartridge Gun being 1:1 or 2:1 is for the different epoxies that we sell. For example the EPX1 is a 1:1 epoxy and the VB1001 is a 2:1 epoxy mix. Getting the correct mix with epoxy is always important but it is a little more important with a 2:1 mix. If you use to much hardner, the 1 part, it will make the epoxy set up to hard and brittle and increase the chance of failure.
