few years back my current house renovation, whole house using MML and the quality is very good. Now i going to have renovation for new house again, and this time i notice MML tiles range like lesser a lot. So i try to see niro and guocera and notice they have more range. My contractor told me don't use floor tiles (porcelain) to do wall as it is very hard to drill and it tends to popup easily (due to its density is high). so ask me choose ceramic wall tiles for wall, but it is fine to choose porcelain for floor. does anyone notice about this? between guocera vs mml which one better?

I think u can buy Davco cleaner from hardware shop
