From the diagram I would guess under 1/8"
.......not MUCH under though
Well, we got the second coat of the epoxy vapor retarder rolled on this morning and the self leveler was poured on about 4 hours later.
...So as far as the "correct" height" I am hoping that I figured it right. It will be close enough.
.............it is, what it is.
Outa my hands at this point anyway.
I must say, that the tech/rep that drove 150 miles down here to help with the install, to teach, to supervise the installation was fantastic. A great personality. I'm guessing he is in his mid thirties. He told me (to my relief) that I got the concrete surface grinding done to his satisfaction. Wahoo, I done good!
On Sunday I did one last vacuuming of the surface, spread out some drop cloths and he went straight to work getting the epoxy mixed. He poured it around the perimeter of the work space and I troweled it out with a 1/8 by 1/8 by 1/8 V-notch trowel.............. I guess you can't pour this stuff too thick. As I was troweling, he started back rolling in every direction to smooth it out. It went very well.
This morning, we did the second coat, but with a 16th by 16th trowel, and again, he back rolled it.
We had to work really fast this time because he added two bottles of epoxy accelerator to the mix. (in addition to the catalyst) Wow did it set fast.
The epoxy comes in a metal 2 gallon container. We needed much less than 1/2 that amount for this second pour. As per instructions, the metal pail with the remaining volume of epoxy was set outside in the parking lot. He's gonna email me photos of the white smoke that began coming out of that can.
5 minutes later, in a cool breeze, the bubbled column of epoxy that rose straight out of that metal can was still 180 degrees according to my hand held infrared thermometer. Certainly it went well over 200 degrees on the exterior part of the can just a few minutes earlier in this massive chemical reaction process.
This stuff is serious, so be careful with it.
This fellas employer is gonna get an email from me. He was absolutely fantastic in every way. Pleasant to talk with, very well spoken when giving instructions, or showing or describing the process we were about to do............... or when simply answering questions. It was a great learning experience. (even tho I will probably never need to do this again)
That said, I can teach the locals if needed on their projects.
When he sends them, I'll pass on some photos of this little project that has nearly driven me to the brink.
I measured the depth of the pour in a lot of places early on. This was just 130 sq feet of floor space with 3/4 of an inch of leveler needed, ........on average. I figured that it would take 13 bags.................... it took 13 bags and we had 1 to 1 1/2 gallons left over.
