Anyone have any luck with an epoxy coating or concrete sealant? I have a new single car garage that I am looking to coat the floor. I plan to diy this project.

I have always liked the looks of grey epoxy on a garage floor, but I have never had quite the nerve to do it. Once you do it, you can’t undo and you will have to maintain ift for life.

2-part epoxy is great but prep is everything. I did a 4k sqft shop with zero knowledge and it turned out great. Drove forklifts on it for a decade without incident. That was a new building, so basically just power wash and acid etch.
I’m not sure what else you’d need to do to an older garage to get the oil out.
I have similar 2 part epoxy on my old pool and it’s just as strong. Didn’t take a bunch of prep because walls are so porous anyway. The only place that failed, it took 1/8 to 1/4 inch of plaster with it. Super good bond. Basically, if the structure beneath holds together, so will the epoxy, as long as it is bonded.

It was Rustoleum “professional”.
This was back in 2009 so their product lines have changed since.

Prep is everything. You need to grind, or at minimum acid etch and pressure wash.

You don't want "epoxy". You want a polyurea(not polyurethane), or a polyasparctic coating.

There are numerous places online where you can buy quality materials. I liked and used Versatile Building Products offerings. I've done multiple garages with their products.

Helm paint sells a product called corotech v400. Very good product. Not hard to put down. Can be tinted to any color. Roll on with 1/2” naps. I use a paintbrush around the edges and on any vertical concrete. 2 coats. Don’t park on it for 7 days

I install this product professionally. Holds up great. As others have said, prep is key. Clean really well. If it’s slick concrete you may want to do an acid wash. Not necessary for broom finished concrete. Have them print you out the data sheet, it has all the directions for mixing and applying.

It is broom finished and has not been used yet. This is for a new home.

My garage is flaking a layer of thin, smooth concrete in various places. What kind of prep would need to be done for this?

Would the same coating discussed here be put on a partially covered back patio?

Thoughts on Ninja Coatings?

Anything loose or flaking up would need be removed first. I would think a good pressure washing would do the trick. A hand grinder with a cup grinding wheel would also work if the pressure washer isn’t enough.

You could do this coating on a patio. However, I personally think other coatings look better for living areas like patios. We do a lot of 1/4” concrete overlay resurfacing with slate texture finishes( stamp rollers). It looks like a real stone or real wood after it’s stained/sealed. Not the solid color, painted, epoxy look.


Ninja coatings seems to me to be a good product. It’s basically the epoxy with the flake finish over the top. But in my opinion, the epoxy and the ninja coatings look best in garages more than outdoor areas.

This is the ideal candidate for an epoxy floor! The v400 would work great.
