How do I remove concrete sealant without damaging stained concrete underneath.
So the back story is I poured a patio with the mixed in stain. Then after waiting the appropriate time I decided to seal it. I started with Behr low gloss concrete sealant which turned the stained concrete to almost a plain grey color. Basically it went on looking like good things were going to happen, but then as it dried it got milkier and milkier.
So on try number two I went to Ace and got a gallon of their laytex acrylic sealant. I put a layer of that on and decided while the overall outcome was not exactly what I wanted (still a lighter color than expected) I was happy enough to proceed. So I finished off that gallon and dipped into the five gallon can of the same stuff that I had purchased from an Ace closer to home. That batch yielded a milky finish as well. So basically I ended up with three different color patches on my patio.
Now I’m stuck with the idea of blowing all this stuff off and starting from scratch. The power washer seems to be doing a fine job of blowing off the Behr covered portion and the spot that I spilled gasoline on while filling up the power washer came off like a dream. However, the Ace stuff is holding tight with the power washer and a small spot where I figured what the hell and put some gas on it seeing if it would work. No luck. So here is the question
What the hell do I put on the Ace acrylic laytex sealant to get it off without damaging the concrete, or jacking up the stain?
