Quick question about floor prep for epoxy-coat

Hi everyone!

I just got my epoxy-coat kit in the mail last week and have spent the better part of today prepping the floor. I plan on putting down the coating next weekend. My garage floor is 3 years old. Here is what I have done so far:

1: Sanded concrete with a 17" orbital floor buffer from Sunbelt, I used 20 grit paper to get a finish that I would compare to 120 grit sandpaper on wood -- Not rough to the eye, but has a nice profle that appears to be conducive to a good bond.

2: Using a stiff bristle broom I completely swept the floor.

3: I poured warm water mixed with a little dawn soap directly on the floor and worked it with a scrub brush.

4: I rinsed thoroughly with fresh warm water (3 times) and pushed the excess out of the garage with a stiff broom.

5: Finally, I poured warm water directly on the floor and used a squeege to pull it all out of the garage.

I am getting no residue on my fingers if I wipe them across the concrete.

Now I have a few more questions. Should I use the supplied etching kit that epoxy-coat supplies, or have I done enough prep work? IF I do need to etch, how many days before hand can I do that process? Does it need to be done shortly before applying the epoxy?

Thank you for any help!

Took my floor about a week to dry after etching - don't plan on coating it for a while after doing the prep work, time measured in days not hours. Tape some plastic wrap to the floor and see if vapor coming up condenses on the wrap, no vapor then its dry.

I had residue on my finger tips after prepping mine and ended up wiping the whole floor down with Acteone and paper towels before applying the Expoxy coat - I thought it was clean but after doing this found out how dirty it was( and that was after pressure washing, scrubbing with Dawn, and degreaser). The wipe took care of the residue too.

As long as you have created a good profile (we usually recommend the texture of 100-120 grit sandpaper) you do not need to use the acid wash. I have absolutely no idea what ^^^^Gloria ^^^^ is talking about. :wtf:

Good job, but do not acid etch. The only areas the epoxy will not stick is where water beads up. If you sprinkle water over any spots that looks slightly shiny and the water does not bead then you will have excellent adhesion.
Most epoxies are unaffected by moisture in the concrete from cleaning. There is only a problem if water is coming in from underneath at a later time and the sun gets onto it. In factories we would clean with water in the morning and coat in the afternoon, even if we had damp spots as long as there was no shiny water on the surface and we never had a problem.

If you are using our kit, please disregard comments made by people not familiar with our product (or any 100% solids epoxy for that matter).
The floor must be completely dry before applying epoxy to the prepped floor.

As promised....Pictures!!!

But first, for anyone on the fence about using Epoxy-Coat -- DO IT! I could not be happier with the product or the results. I used 1 full kit to do 430 square feet, and have another 260 squre feet to do in the next couple of weeks. My dad helped me with the application and was so impressed he will be ordering a few kits to do his garage and barn!

I purchased the Taupe kit with olive, graphite, and white flakes.

1/3 of the way done (3 car garage)

Hi Christine, what do you think has it been to humid around here to put the epoxy down?
Mostly I've been waiting for the floor to dry after I acid washed it.
