t’s November which means chilly temperatures. When water temperatures move in the direction of
freezing, that can mean trouble for unsealed outdoor surfaces, like flagstone.
Over the past 25 years, I’ve cleaned and sealed just about every surface outside the home. But lately, with the introduction of the saltwater swimming pool, I’m getting a lot of calls asking why the flagstone is flaking into the pools. After phoning many
local pool installer, this seems to be a common problem: the flagstone flakes and discolors the pool inside.
So why does this happen? When water temperature moves in the direction of freezing, the water expands. When rock or flagstone moves in direction of freezing, the rock contracts, or gets smaller. So when temperatures change throughout the day, the rock and water move in opposite directions, causing flaking.
