DIY is a relative term. Someone is always doing the DIY if you know what I mean. The stain I used is the same your contractor used. Stain-Crete by Increte. Sealed with the same stuff your contractor used, and prepped the very same way. My concrete just didn't hold up to the foot traffic and chair sliding action. The concrete itself started to pop up in chips in high traffic areas. The way to do it is to know you want it done when they are laying the slab and have the concrete prepped for it from the get go. I think 30 years down the line when carpet has been covering it was not the ideal situation. Your garage looks like a million bucks!
