i just read quickly through the links and i should say that those epoxy etc coatings will wear out as they are to my knowledge generally used to seal concrete for the purpose of hygene, to prevent mould or mold and bacteria particularly when fitting carpet on concrete . some of the products mentioned seem very hard wearing , but you will need to check durability because the grit on your tires will wear coating very quickly . hey i said tires instead of tyres , see what you guys are doing to me . i seem to remember that tiles with a black glaze would wear quicker than any other colour due to chemical composition , but ceramic glaze technology has advanced in recent years so just don`t waste $$$$ on stuff that won`t last .
