Properly done, it will not be a problem.

Thanks again poolguynj... what about flagstone coping and salt water? Does the flagstone require sealing from the get-go and every X # of years?

What if you don't seal it?

It depends on the stone. Oklahoma is reported to be significantly softer than the Penn I see here. the Penn has no problems but the Oklahoma has been reportedly needed sealing.

Basic rule when selecting stone. If you can scratch it with a nail and it leaves a white line, pass on it. A gray line or no line is OK.

Sealants vary by region. I encourage discussing with the stone dealers and avoiding the big box store stuff.

Thanks for the info / help. Much appreciated.

Have spraydeck and salt out here in Arizona for 6 years. No problem with it at all. But walk on it in the summer with bare feet, too hot for my feet.

Hi neilaz.

Thanks for your posting and info.

Are you saying even the spraydeck gets too hot in summertime? You guys reach about 110 degrees?

What color is your spraydeck?

Any surface gets hot when the sun is blazing on it at high temps. Spray deck is the coolest choice. You absolutely have to seal and reseal and reseal flagstone if you have a salt water pool. Spray deck is not really affected, particularly if a polyurethane sealant is used on it.

Our spraydeck is a tan light tan. The only way to keep a deck cool in 100 is to install a sprinkler system in or around the deck. I have seen a cement paver deck that had sprinklers installed in it to keep cool. That and shade is your only cool friend.
