Limited instructions though but since I knew what I wanted and how to use it I had no problems. Preparation is key. Now only time will tell how it holds up. Review: WHO is measuring this stuff?? - Save your time and money and buy something else! I got a total of 4 of these-I bought 2, and the company (a long time ago) sent me one replacement, so that's the one star, for that one time I got customer service. I then bought another, for a total of 4. Here's my complaint: out of the 4 units I got, no 2 were alike in the measured amounts of the included 2 part epoxy. The first 2 had epoxy content that was off by a full 50% - one of the units had half as much "epoxy" as the other, and a way different amount of hardener as well. I actually got in touch with them that time, and they sent me another unit. THAT unit didn't match either one of the first 2. When I mixed the closest 2 together, it took OVER 10 days for the epoxy to cure- I could still push my finger into the surface at day 8. I never bothered to mix up the last one- I have NO idea what the actual ratio of part A and Part B is supposed to be, and there's no way to tell by comparing the 4 different units. I called their 800 number a total of 5 times across one week and left 5 messages, and got zero reply as of a month later. ## Features - This epoxy mortar provides excellent flexural, tensile, and compressive strength when patching or resurfacing concrete floors (See Specification Sheet for details). - Most effective for floors that require patching and/or resurfacing, but do not require a lot of chemical and impact resistance. - At 70 degrees F Pot life of 20-30 minutes; May be recoated in 6-7 hours; Light foot traffic in 12-14 hours; Full cure (heavy traffic) in 2-7 days - Apply to a thickness of 1/8" to 1/4".
