Renew Your Concrete Patio

Two things: 2 cups of household ammonia to 5 gallons of water is a better neutralizing wash, it doesn't strip the salts from the slab in case concrete dye or more acid stains need to be applied at a later time.

Second: A garden sprayer and a circular saw? Really? Last time I checked, water and electricity don't work well together. Even on a GFCI protected circuit, you're taking an awful big risk to avoid paying a few bucks to rent a wet saw, which will be easier to use and produce more consistent results. I'd rather not wear my eye protection than spray water on an electrical tool. Best you can hope for is you ruin the saw and not your life.

Other than that, very accurate, well written and thought out advice. You are correct in stating that surface prep is the most important step in any acid staining project. Typically, it takes two to three times longer to prep and mask the surface than to appy the stain and sealer.
