My bluestone coverlids were finally installed. My PB suggested sealing the thermal bluestone coping and coverlids with a penetrating sealer because I have a saltwater pool. I asked the local supplier store of bluestone coping and they recommended Stainproof 40SK (Dry Treat brand). The PB said okay, yes. The sub who installed the coping/cover lids said he never used that product and uses something else (trying to find out what).
A) Should I have them seal the bluestone coping?
B) Should they use Stainproof 40SK or somwthing else?
C) I also have an irregular bluestone patio that I installed 6 years ago and never sealed, adjacent to the pool. I'm not sure if I should seal that too? It is obviously not thermal, so will it penetrate differently? It isn't supposed to alter color...
Thanks in advance for your advice.
