<BR>
Tell that to my own concrete, when a customer decided to spill a gallon of paint, and we used our soy-based paint stripper and it tore right through the spilled paint, sealer, and soy-based stain so the concrete ended up looking bare. It doesn’t have to be an acid etch to “etch” up the sealers. Ultimately, the success of the approach depends on the concrete and how deep these finishes/stains were allowed to get. If the concrete was messed up, they may well be sitting more on top than in it.<BR>

</SPAN></FONT><BLOCKQUOTE><FONT SIZE="1"><FONT FACE="Arial"><SPAN STYLE='font-size:9pt'>Jason...acid etching the concrete won’t remove the sealer and paint stripper won’t remove the stain. Acid etching only works when the acid has “access” to the free lime in the concrete. The sealer...seals it...so this isn’t an option. The stain should be in the concrete and not on top of it, so stripping wont be effective. The only way to remove the sealer and stain would be to shot blast. <BR>

</SPAN></FONT></FONT><BLOCKQUOTE><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:10.5pt'>Can you etch the concrete to remove the current sealer, strip the stain with paint stripper, let the concrete properly dry and cure, then go back and stain and refinish?<BR>
<BR>
Also – any concrete will naturally have a certain unpredictability in the finish pattern, with random burnishing and highs and lows of color. So I typically recommend take advantage of that, fly with it, and stain with a creative, random, very cool stain pattern. You won’t know what’s mistake/old mess-up and what’s intentionally part of the pattern.<BR>
