That's great gas prices. Lowest I've seen around here is $1.96
 
Koster........clean and apply 14 2.4 gallon units across about 4K square feet in an elementary school multi purpose room

They didn't say but pretty sure we're going to lay 2MM Mondo tile.

Concrete was extremely rough. Really sucked up the epoxy.

Looks like Ardexes two part epoxy water proof coating . What a hump to roll.

We've used Ardex moisture stuff and I was trained both at the union school and by their tech reps on site. I never saw anything like the Koster epoxy from Ardex.

It's all very much a hump to roll out.........you will always need 1-2 COMPETENT men working with you.

What I remember from Ardex was they had three different mixes. The one we used they wanted us to "broadcast" sand across the wet epoxy to create a bonding texture to avoid the need for a primer for the patch to bond to the non-porous epoxy.

It's MUCH easier to just use the Koster primer-------NO F'n sand to broadcast and then sweep away. Otherwise, if you don't use the sand Ardex wants you to use a 2-part epoxy primer for the patch to bond to.

That's not in any way economically feasible.

Epoxy makes me want to gag.

We did that same sorta thing a couple years ago at a local maritime and history museum. The rep said their epoxy would control moisture on a 3 day old concrete pour. :eek:
Products were made by UZIN. First coat went over the concrete that I surfaced with a grinder. It was poured on and I troweled it, then he back-rolled it.
The second coat went on the next day, but time time he added 2 bottles of "accelerator" (in addition to the catalyst) into the bucket.
This coat used a much smaller trowel notch, then he quickly back rolled it.
Then we broadcast the sand and waited 1 1/2 hours.
We swept and vacuumed, then immediately went into the pouring. The UZIN products are amazing. The area we leveled was jut 10 feet by 13 feet. I liked the sand as a bonding agent for the epoxy but on a large pour, I can imaging it being a PITA, but still worth the effort.
... I thought the UZIN system was very good and a user friendly product.
 
Wow. I had no idea about the whole sand "broadcast" thing. Makes me appreciate commercial flooring installations more if that is what you guys have to go through.
 
Yeah I never liked the sand treatment deal.

One of the dumbest ideas of all time. IMHO

A resilient guys worst enemy is the grain of sand that works it's way onto the glue and under the goods-----------!!!!!!

So bring in BAGS AND BAGS of sand and toss it all about. Then try to sweep and vacuum it all up.

Yeah right. No one's going to get in the way on a construction site when you're throwing elbows fighting for every square inch of working space in a hailstorm of flying ******** from the Third World.

Better not go too far down that road.
