I would like to ask you guys what brand of polymer sand you are using. How do you like it? I was using Techo, but on the last few jobs I noticed it was leaving a haze. Please, no instructions. We always make sure the pavers are dry, sweep it in, blow it off and then spray a mist. I called one of the Techo salesman and he said that others complained about the same thing. He then assured me that it would weather. I believe him because on the first job where I noticed the haze, it is beginning to fade. However, I don't want to have keep explaining to homeowners that it will fade and not to worry about it, so I am switching.
