Please tell me the good, the bad and the ugly about porcelain coping. We’ve had gunite for 2 weeks and I finally found a coping I love and it’s porcelain. I’m concerned about it being slippery and/or too hot in the sun. We’re in central Texas with no outdoor shade and small kids. Here is a picture of the matching porcelain tile that will wrap the spa with our waterline tile. The deck will be concrete with an acrylic cooling coat. Help! I am crippled with indecision.
