Where can the below mentioned epoxies be obtained? What brand or
product do I ask for when I get there? Is there a website with info for the
epoxies? Maybe I just missed it, but I've been reading about these epoxies
here on this reflector and have found no specifics on what the product is-
just a reference to "epoxy".
Unfortunately??, my local concrete supplier had no idea why epoxy was
necessary. His advice this morning was to simply just pour a new batch of
concrete any ole' time over the old. So which is correct- join two
separate pours with epoxy- or not?
Thanks/73
