most retarders , well at least the ones that i use, will dry. the first one i did turned out great but , the amount of work put into it to scrub the top off wasn't very fun. i would suggest spraying the retardant on heavy (not so it is running or puddled), i never worked the retarder into the surface, but you can try it. leave it sit until you think you can spray it off, start with a very light mist. sometimes waiting a little longer is better, when you spray off a couple feet you will notice you will have to broom & water off alot of sand that accumilates from the process. when you are spraying it off you will need to touch up bald spots with a broom. it works best with two people. retarders are safe otherwise they wouldnt be making them.
