Yep, they always sell it like it's maintenance free, people seem to love it as thyre driveway though and everyones having it, the way I see it the more people have it installed, the more work we get!
I'm looking into a similar thing to stonecolor, looks great, can imitate pic with it, and can be sealed with acrylic to give a gloss, again water based and also limitless colours availible, semi translucent colours to give a atique finish aswell ,will keep you posted mate as I'm not sure if it can be applied on top of acrylic yet, so might no be much use unless you strip the drive
