I have a cement patio that was sealed with Glaze N Seal Penetrating Sealer, Natural Look. I'd like to remove that sealer and use the Glaze N Seal Wet Look sealer instead. I'd like to remove the sealer without too much damage because the cement is colored and stamped. Somebody suggested I power wash the patio with a 3000+ psi washer. Somebody else suggested I use diluted muriatic acid and basically etch away the sealer, but I don't think I'll be doing that. What do you guys think? I'm getting ready to rent a power washer, but I'm still open to ideas. Thanks. -mangoango

The power washer won't do much unless you've got some spots where the sealer didn't penetrate or bond well and you can get the water stream up under the coating. Go with the muriatic acid, it's not that strong. It's not the kind of acid that eats through supertanker hulls in 3 seconds. Still, protect yourself (goggles, gloves and old clothes). Be sure to rinse thoroughly, then rinse again.
