Check with Your local Paint Store (Sherwin-Williams, etc) a lot will depend on the age of the concrete- the newer the worse time You will have, the older the better.
Concrete is always curing.
You can check with Home Depot, etc but they don’t just deal in coatings.
That’s ALL a paint Store does.
Prep is VERY IMPORTANT!!!
You will be using a 2 part coating but get the Pros at the Paint Store to help You.
Good advice regarding the local Paint Stores. Most of the people at ‘Big Box’ type hardware stores tend to not have any real idea about what they’re selling, and earn a little over minimum wage. I believe the only requirement to work in those places is having the ability to lift 20lbs, give authoritative bullshit answers, and fog a mirror. Hiring people that have actual real knowledge of their in-store departments would cut into profit margins, which are about ALL that matter for such places.....
