Hi, I recently install my very first pool. Based on being handy and on budget mostly, we tackled the job on ourselves. So far so good, but after we poured the sidewalks and apply Sun deck problems started. I bought the "Desert Deck" (supposedly another brand of Kooldeck) from a local pool supplier. I ask for instructions and they told me that for every bag should be mixed with 8 small 25lbs of marble sand and white cement 50lbs, then apply to freshly poured concrete with a brush then throwel before it hardens. The first batch I only use 4 bags of marble sand instead of 8, second batch tried the original formula. The first batch held out pretty good, but the second started crumbling within a week. I asked around to see if theres a sealer or something that could add more strength and shine to the deck. First batch even it held is very pale and opaque. Also let me know whats wrong with mix. Thanks a lot.
