Patch compound for Polyurea coating?

[1967marti]

I'm wondering if there is a specific patching compound needed if i wanted to fill in a few small gouges in my concrete floor before coating with a Polyurea floor coating.

Will any off-the-shelf epoxy concrete patch work? If not what would you recommend?

Thanks!

Marti:

If you are in a pinch bondo will work.
Real, Real small?
You can mix some epoxy adhesive and sand.

ya, they are small... most are about 1-3 inches long, 1/2 inch deep and about an inch wide. I was thinking epoxy and sand because it will see some steel wheels from fork lifts and machine feet. there are enough gouges in the floor for me to be looking at a large tub i think. Which one of your products would you reccomend?

Use play sand and mix it to a peanut butter consistencey with epoxy.

Better yet, use silica sand. It's clean and will not have impurities in it. Play sands often are not clean and that will degrade the epoxy.

Correct, do not use play sand. If you can find it, use kiln dried silica sand.

Lowes has been carrying it. If you have trouble, go to a brick & block masonary outlet. they will have it.

ok, so what im getting is the following:

Mix sand with ANY type of epoxy and fill the cracks?
I think I saw a little kit for the big-box epoxy floor coatings at my local lowes/HD. I'll see whats included in the kit and go for that if it's more bang-for-my-buck than buying a few tubes of epoxy and sand... What about using the simpson's strong tie brand epoxy? I have a few big tubes of that left over from a project and it's made to bond to cement?

Quikrete play sand is a cleaned dried silica sand.

AJ, these guys are diy dudes (and dudetts) you need to explain to them. I don't use quikrete anything so I'm not familiar with it.

That was my mistake. I'm almost positive it's the only play sand you can get at lowes or depot though.

I think it depends on where you are located. I bitched and moan to my guy at Lowe's and suddenly have pallets of it. Some stores are sensitive to the fact that it can kill ya if you snort too much of it. I must say airborne silica isn't something to play with but if they took everything off the shelf that could harm a dumb *** hair brain misusing it, then we would have empty shelves. Good ol' gurvment protecting us against ourselves.
