      • Use with 9500

      I wanted to get the absolute best results so I contacted Ghostshield and told them my situation. They recommended 4500 followed by the 8500 for my badly worn 98 year old concrete. I had already purchased the 9500 and had it laying around and they said it would work as a substitute for the 8500. After cleaning, acid etching, and neutralizing and letting the concrete dry I applied the 4500. Apply it thinly or it may show white residue. The residue can be scrubbed off. I let the 4500 cure for 7 days then I applied the 9500--2 coats. I had significant efflorescence, dusting, etc prior to sealing with this two coat process. I can tell you the efflorescence has been reduced significantly and water beads right off. Hope this helps someone trying to find their way in the crowded world of concrete sealers.
