Clear coating garage floor recommendations

[hardate]

Just purchased a house built in 1992. The 3 car garage (approx 800 sq ft) which is heated and cooled. I'm currently grinding the concrete garage floor to expose the aggregate some and remove any rust and oil stains. The concrete is in excellent shape, only a couple of hairline cracks, and it does have a floor drain. Ultimately I am wanting to protect the concrete from future stains and is easy to clean/maintain. I'm looking for DIY recommendations for a clear coating, that will provide protection, is easy to maintain or clean up spills, has a wet look, is slip resistant and won't yellow over time (the door face the south and when open sunlight can hit 50% of the floor). I've done a lot of reading and research, and what seems to be the common recommendation is a combination of epoxy and urethane.

All input or recommendations are greatly appreciated, including specific products. Thanks in advance for your replies and time.

I'm sure the experts will chime in soon. My understanding of using the epoxy/urethane combination to avoid yellowing is that the urethane is tinted so the epoxy is covered by a pigment. I think if you go with clear urethane over clear epoxy, the floor will eventually yellow.

If you just want a clear coat, I think you would use several coats of clear urethane with an anti-skid like Shark Grip or another non-yellowing clear coat.

I would use a couple coats of a polyurea or polyaspartic. I would use a tabular alumina in the final coat.

Thanks for the replies.

Any recommendations on polyurea or polyaspartic products I could purchase locally or online that will accomplish my goals and are easy on the wallet?

After grinding the concrete floor, is it necessary to put down a primer coat prior to putting down the polyurethane or polyaspartic coat? Trying to understand if this is necessary since I'm only putting clear down. What are the benefits of putting down a primer coat? Thanks.

You are going to need to do multiple coats of clear. Depending on what you use, the first coat may be your 'primer.' For example in our polyurea, I would not use a separate primer. I would just understand that the first coat is going to seal and the second is going to build mil thickness

For the LegacyHD6525: How many coats are needed? What is the coverage per gallon for each coat? What is its weakness? Thanks.

 

[LegacyIndustrial]

2-3 thin coats, coat 1: 300 sq ft per gal, coat 2 :400 sq ft per gal.
It does not like gasoline but on the flip side is easily repaired if an issue occurs.
