 it just didn't hold up from i had little kids at the time and just them scooting in and out the dining room chairs with pads on it was denting it and it was crushing it and it just didn't work and so in these instances like this i'm going to be honest i would just tear it out and put in a new floor and i know that's expensive but i think for the health hazards that are in the aluminum oxide if you try to sand that down and get that dust all over the house that's not great
