Question about Blue Stone and heat

[cteal]

Hi there! We are currently DIY'ing our own pool and looking at decking options. I love the look of Pennsylvania full color bluestone but read that it gets really hot and is very uncomfortable on your feet. So, I called a local stone company to inquire about other stone options. They told me if I sealed the bluestone with 2-3 coats of polyurethane that it would considerably lessen the amount of heat the stone holds. Is that possible?

This is a really large stone business so I would think they would know what they are talking about but wanted to see if any of you had any input/advice.

Thanks,

Bluestone gets very hot. I don't think that sealer would help much. Mostly, it will just make the stone slippery.

My pool has bluestone coping and it was fine I never noticed any particularly high heat on it.

My brother in law has a bluestone patio in Massachusetts and it didn’t seem hot when we were there in July. He also has a bluestone hearth in front of his fireplace...

Our Bluestone coping is a bit hotter than the concrete decking. So very hot. Too hot to stand on for long on a 90 plus degree sunny day.

As for coating it with polyurethane, that sounds like a really bad idea near a pool. Super slippery I’d expect and something more to maintain.

Thank you so much for your responses.

I have a couple pools with bluestone decks, it gets so hot it burns my knees when I open skimmer.. one family walks around on pool floats, I don't blame them, too hot.
