RSPro Hexatraction Waxless Surfboard Deck Grip (Clear)

Will this work for pool steps on epoxy painted concrete

Will this work on a cork top surfboard? I have a Hyperlite 8' surfboard, it has a rear traction pad so seems 3M adhesive works ok but how about this?

Do you have this product in white?

I would like to cover a 9'6" longboard pretty much head to toe. How many packages of these will I need to order?
