screwed up too. after we stained it wife put on sealer when it was too cold and waxed right away. now have whitish marks and cloudy patches that are not going away. how do I remove them without screwing up the floor? sealed using ****** **
Hello Tom,
   I'm not familiar with the sealer you used. It sounds like a solvent base. If so, then it likely didn't cure long enough before applying the wax. The water in the wax may have penetrated the sealers surface which would result in cloudiness. You would be wise to speak with the sealer manufacturer on how to fix it. They'll likely have you to strip it down and reapply the sealer and let it cure out before applying the wax. Fyi: Solvent base sealers require a minimum 72 hours cure time in warm weather. Longer in cold and/or humid weather. Also, the concrete has to be bone dry when applying solvents. Most sealers require it to be 40 degrees F and above, which includes both the air temp and the concrete surface temp, for application. 
Note: You can also find instructions on stripping sealers by searching the blog archives.
I hope this helps

Should I Acid Etch the Concrete before Staining it?

Ask a Pro
  Q. -  I have looked at other brands of concrete stains and most have an etching chemical that has to be applied first and depending on brand depends on the brand of etching chemical, if I buy this product do I need the etching stuff, and what brand if so???
Hello Blair,
  A. -  Concrete Camouflage stains are true concrete acid stains, which means they have the acid in them, and so you don't use any etching products during clean and prep or before applying the stain. Products that call themselves concrete stains, yet require the concrete to be acid etched and/or acid washed prior to application are disguised paints and should be avoided if at all possible. Some examples would be acrylic stains and semi transparent or solid color stains. But the one that really cracks me up is any product that pitches themselves as eco friendly or a safer alternative to acid stains, bragging that they have no acids in them. Then they tell you that in order to use their safer, better, eco friendly stain, that you need to acid etch the concrete first. Of course using a far stronger solution of acid than the diluted muriatic/hydrochloric acid (swimming pool acid) that is used in the actual acid stains. Not to mention a another step added to the process.
