I completed a renovation/expansion project on my 3 car garage late last fall that included pouring a new floor. I had asked for the concrete guy to seal the floor. I did not specify a product but made it clear durability was my main concern. He used an acrylic sealer, but it became clear pretty quickly either the product was not up to my requirements or the application was lacking. My initial thought was that the floor just needed another application of sealer, but as I began to look at alternatives I discovered people were putting rust bullet (which I have been using for years on cars) on concrete and it piqued my interest.
I know the recommendation is to grind a floor that has been sealed before putting down rust bullet, but given the main problem with my sealed floor was that it would still absorb liquids, I decided to take a chance and see if I could apply rust bullet directly on top of the existing floor. A couple weeks ago I put down some sample patches and threw typical abuse at them. I was happy enough with the results to pull the trigger on the whole thing and ordered 5 gal from Justin.
I ended up filling my control joints with Sikaflex SL, and rolling 2 coats of RB this weekend (with a 3rd coat in the center bay). Prep was pretty minor, just a pressure washing and some spot treatment with metal blast for a couple very minor oil spots. Appearance was far down my list of priorities, but I'm happy with the way it came out. The increased reflectivity of the surface has also been an added benefit.
