Yeah, what's up with the idea that acid etching provides a decent surface for garage (or almost any) floor coatings? Or that garage floor kits actually work? Or "garage paint?" Yikes. Time for the master class...

I just finished a 7k square foot auto storage room with all SW products. Two coats macropoxy two coats HS Polly. The floor had been sealed already and was mechanically troweled, so it was the worst case scenario as far as amount of prep required. 100+hrs grinding. It looks great now, we'll see how it wears.

In my experience acid etching only works if the Crete is already rough finished. If its smooth, acid usually won't do the job. You can't go wrong with mechanical grinding. It's just expensive and time consuming.

No offense but I'm tired of painters listing epoxy floors as a service they perform. Epoxy flooring is too complicated for most painters.

ShieldCrete is an inferior garage floor coating. Acid etching is not sufficient for adhesion. Etching is like painting latex over oil enamel without abrading.

You are right. I never bother with acid, and just diamond grind. I have seen many jobs my old boss did with acid fail. Even ones that should have been ok. The weak link was the etch. Its more expensive to do it again!

Where do you go to find a class. I've been doing a lot of garage floors lately and now you guys have me nervous.

Urethane top coat for sure! It has excellent UV protection.

Wish they had classes around my area. It's a good thing to learn and get into to do it right. Lots of people like the look and the cost of the raw material really isn't that much for a typical garage.

Exactly. I'll guarantee the HO drives like a maniac, doesn't take it easy when nearing home, parks it and shuts it off. I spent the better part of two decades wrenching on cars and people treat even very expensive cars like crap, and if they treat their cars that way, i guarantee the same goes for their garage floor. A smart car owner always slows it down for the last bit on the way home from "spirited' driving to let the turbo, oil, tires, brakes, etc all cool down first. I can't tell you how many people have warped brake rotors by putting on a parking brake after not letting the rotors cool down first.

Providing a garage floor coating of some sort helps protect the concrete from damage. Prior to sealing the garage floor, concrete should be brushed and cleaned thoroughly. Otherwise, stains will be trapped in the concrete for years to come. Resurfacing the area may be more efficient for some floors than removing a stain, then resealing the floor. Even well-sealed floors will be stained if a mess is left unattended. Some garage chemicals will eat through a beautiful, sealed garage floor in a matter of hours.

We always tell people no parking in the garage for 7 days, if they drive more than 30 minutes home from work let the tires cool down for the first 30 days, since we started using Corotech System we have not had any issues (except a home owner spilling gas on his freshly coated floor)

This isn't the xylene based H&C?

i looked up the product and it says you mix it. Never used this stuff and now I'm scared of garage floors!

Been using H&C, but the xylene stuff in the red can. We acid etch the floor with muriatic and or soda flakes, run the hydro scrubber over it a few times, then roll it on. Never had a problem with it.

All these gc flip homes we have been doing call for grey xylene based garage floor coating on the work order. I have been using H&C xylene in the red 5 gallon can.

Sorry for your troubles Repaint, garage looks real nice tho.
