Have a concrete garage that is crumbly and dusty and unable to get concrete dust out. Not completely flat, can this be put on this type of surface? Will nitro rolls work?

Since our Diamond Nitro Rolls are made of flexible polyvinyl, these rolls are very forgiving and can be installed over a floor that is not totally flat or perfect. The only issue would be if there are sharp imperfections in the floor, they could tear the roll when driven over.
