   "The defect I found in every single $62 kit was that more than half of the part B was hard as a rock and since I already opened the paint I was unable to get a refund. "

   Why not.

   Have you talked to Quickcrete support?

   Did you talk to the store manager?

   You can get a refund or replacement for it.

   Sounds like the shelf life is not too good...

   We use Sika epoxies with great success and have no trouble with the product setting up too quickly. It requires 2 coats, the first is applied with a little thinner added and the second is installed as directed.

   Two part expoxy is the norm.

   We're half way completed a floor as we speak. About 125,000 sq. ft and it takes a week and a half to complete. First we shotblast the floor, install the primer mixture the next day, finish up with the final coat the following day. We do about 20,000 sq. ft. a day.

   Floor is good to go after 48 hours and will last for 20 to 30 years.

   Gabe -How well would the epoxy finish hold up in a welding area? IIRC, the melting (distruction?) point on epoxy is only about 500 deg. F. I do remember the old Caterpillar plant where they used wooden beam end cutoffs in the welding area (soaked in used oil from the equipment), and that flooring certainly survived for many years.

   The epoxy is used in production/warehouse areas to protect the floors from constant forklift traffic. We are also concerned with protecting clean rooms from dust etc.

   Never used epoxy for welding shops.

   I think that the temp is much less than 500.I have removed expoxy before by heatint it up in the oven until getting warm and soft. It has been a while, but I think that 300F will do it..

   Just did a quick Google search and the site I looked at said that epoxy had a melting temperature of 155 - 195 degrees C. And right you are that ranges from 311 to 383 degree F

   Do you follow the sprayer and sprinkle the little flecks over it??

   Epoxy flooring is not sprayed on, it's spread with a squeegie.

   When I read that you did 20,000 sq. ft. a day, I thought you must spray it on somehow.  I was trying to picture what kind of a sprayer you would use to do a job like that.

   Now I'm more surprised that you actually do spread it by hand!!

   What is the time frame that you have before the stuff starts to get tacky and you can no longer apply it?

   The open time for the stuff we use varies dramatically with the temperature.

   What is the time frame that you have before the stuff starts to get tacky and you can no longer apply it?depends on temp and alot depend on humity. I have seen some that set in twenty minute, walk on it in 90 minute and then one I had on a humity day, it took three days before you could touch it, had to turn the a/c on.

   If it's about 50 degrees, you have about 2 hours to put it down and blend it in.

   If it's 80 degrees, you have about 35 minutes.   That's why I only do this on cooler days.

   Sounds like poor storage. A lot of this material cures by the heat from the reaction of mixing A+B. So if its stored in a hot/warm area it will "cure" without the other part. Should be returnable. Call Quickcrete.
