Epoxy Floor w/o Etch and Grinding - Just Primer?

[WKDiesel]

I just completed my Garage. After pulling up the ram board I'm not to happy with the way the power trolled floor turned out. Too many swirls and there are some lines / curing mark where the tape was.

Now I'm looking at epoxying the floor. A had a company that came out, which was recommended by a few friends who had their garages done by this company. They are telling me that since my concrete is new and clean they can just use a a penetrating primer and skip etching and/or grinding the floor.

Are they pulling a fast one on me? Every resource I found on the internet on this issue seems to recommend grinding or at least acid etching.

I would recommend staying away from such a company. New concrete in particular needs proper profiling due to the troweling which has the effect of closing off many pores. I suggest reading the article in the link below to get a better idea on how to choose a proper floor coating company or contractor.

Hi
Our opinion is "Run Forest, run". Anyone that doesn't want to prep should be avoided at all costs.

grind or etch. We have a good safe eco etch product.

I had a floor coated in a new house a few years back with Arizona Polymer Flooring Granitex. I spoke to the manufacturer and asked if any of the prep could be eliminated since the house was new and the garage floor never driven on. Short answer....no way. It had to be ground, etched and prepped just as any older floor.

Given the cost of installing a new floor coating, and the expectations I had for longevity, I didn't want to risk durability to save a few dollars.

I ended up finding a company that diamond grinded the floor prior to installation

Beautiful job. What product did you finally decide on using?

The contractor used a brand called Purepoxy. 100% solids.
