Anyone have Concrete Topping product experience?

I'm looking at coating a concrete garage floor that's had settling and cracks, due to being 50 years old in an extreme weather climate. I know I need to clean the floor and etch the surface with muriatic acid solution, as it's had a lot of petrochemicals on it over the decades.

I'm considering grinding the cracks open and the high edges down with a diamond blade in my 4" side grinder. Of course vacuuming up all the dust and dirt, as I go.

There's a couple of different products for topping concrete driveways and I wondered if any of you have had experience with them? It looks like I'm going to have to screed it, unless there's a self-leveling version of it out there.

Or should I just use a hydro-concrete product and patch it and then epoxy coat the whole thing when done?

Or I will seal it, and I might even dye/stain it with concrete dye/stain first.

What's been your experience on this?

    We had a carport and when we converted to a garage, the building code required a thicker pad. We etched and framed up, then pour new ready mix on top of the existing pad. That was around 1995 and have had no issues since.

    As for the dye/stain, it would be my recommendation to add the stain in the wet mix. My brother-in-law was a mason and he said this always produced the best results for him.

      Pouring needs to be done in a certain temperature range. I have info at work if you need specifics. In regions that have extreme temps, there are additives to help the mix. The company I work for has a ready mix division with delivery in northeast to Maryland. But you are good to pour in warmer weather. Once it is set the cold won’t affect it.
