We had a new in ground pool built spring 2013 and there is approximately 1,000 SF of concrete decking that was installed at the same time (late May 2013 on patio). For the past two seasons we've noticed that cement dust in getting on our feet and in the pool. At first we thought maybe the pool water was evaporating on the deck and leaving a salt residue. We first noticed the dust on our feet as we were leaving foot prints on the wooden deck steps after leaving the patio. Then we started noticing the gray cement dust clogging the filter cartridges and ultimately collecting in the deep end near the drain.
When inquiring with the master pool builder (which by the way has not helped in the least with anything) stated that they have never seen this in 60 years of pool construction. When the concrete contractor met us in person to look at the decking, he said this is completely normal and only lasts a few years until the top layer wears down. Contradicting stories led us to our own research. All three independent concrete contractors and testing/inspection folks we spoke to suggested that the concrete was finished too soon while still too wet. Consequently, our concrete contractor suggested a heavy power washing to fix the problem. When they came to power wash, they casually mentioned that they would be back after the weekend to seal with Ardex Concrete Guard.
So finally, my questions:
1) Has anyone else had excessive "dusting" from a new concrete patio? If so, how was the problem cured?
2) Is there an effective way to restore the cartridges that are severely clogged with cement dust?
3) Has anyone used Ardex CG? We are not interested in changing the appearance of the patio and don't want it to look constantly wet or shiny. Anything I find online leads me to believe it is a clear gloss and will be shiny.
Thanks!
