New 2500 sf garage Supercoat ?s

[docjay]

Concrete will be poured this Thursday.....I plan to wait 30 days prior to applying Supercoat
Couple of ?s:
I plan to clean the floor prior but do not plan to acid etch since it is new unsealed concrete......is this ok? I know etching is probably better but would rather not if the result will be similar.
Can I "get" by with one coat of epoxy and two coats of clear?
Walls and ceiling will be white 14 foot metal panels...I plan on smooth, no flake floor ........give me your opinions on ivory verses sandstone colors?

Best to not skip the etch. It's asking for problems. The secret to a good job is in the prep.

You also might be better with two coats of epoxy and one topcoat. Epoxy without a primer coat can often be uneven and blotchy and two coats of topcoat would just seal in a potential problem.

Tens of thousands of proven coating jobs here use three coats. Primer, epoxy and topcoat. Just our opinion.

Supercoat states that concrete treated with a sealer should be prepped by grinding and that smooth troweled floors may require acid etching. If none of the above apply, then they recommend a good cleaning before application.

These recommendations by Supercoat are lenient compared to industry standards for epoxy in my opinion. The number one failure of epoxy coated garage floors is poor surface preparation. It has been argued in the past that a new pour with a troweled finish is more susceptible to failure if not prepped properly as compared to older concrete. The troweled finish effectively closes off some of the pores that the epoxy needs to penetrate in order to form a mechanical bond. New concrete tends to have excess laitance at the surface which can affect the bond as well.

My recommendation would be to acid etch the surface beforehand, but ultimately it's up to you.
