RCP USA Adhesive Fast Curing Epoxy- for Crack Repair (6 Pack) - AMZ-RCP6H

I purchased 12 dual tubes ($$$!) and found that when applied correctly, the epoxy is great for sealing cracks in my garage cinderblock walls. It hardens like rock.A couple of comments to be aware of: 1) For DIYers: Make sure you follow the instructions about not using epoxy until the color is consistent. The first 10" or so of bead mix is not usable and won't harden because the epoxy doesn't have adequate mix of resin and hardener. I applied some of this incorrectly mixed epoxy, and it doesn't harden. 2) COMMENT FOR RHINO: About 4 of 5 tubes, a seals pops in the applicator gun, and I got either resin or hardner all down the inside of the tube. Not a huge loss of material (maybe up to 5% on a seal break), but enough for me to think it would be nice to have it in the walls and not on my applicator gun. Also, it's a real pain to clean up each time. >>> Rhino should fix the seal thing. <<< Did not drop my rating of the product because it IS good epoxy.So between the first 10" not being usable and the predictable loss of material due to seal breaks, expect to not use the whole tube. At some $30 a tube set, it's important to know.
