I am using a plaster company to do our reservice on our 1994 SWCG pool. We are going with the white plaster with 30% blue Quartz on their recommendation for longevity. I've researched it quite a bit and with our budget and our long-term outlook, that does make sense for us even though a pebble would be nice too.
My question is, we are keeping the flagstone coping in place but replacing the tile. When you see the pic below, the top of the spa curvature will be covered in new flagstone. Obviously, there's no way to get it to match perfectly. With a sunbleached as my coping currently is, I was kind of thinking about using a concrete-type stain to refresh it and to make it possibly match better.
Since this pool has been CWCG it's whole life, should I be concerned with how much salt is embedded in the pores of the stone over the last 20 years as it relates to using a stain?
Does anyone have any thoughts on the matter? I appreciate any guidance you can share.
