I scrubbed the milk stains off of the two coasters I *guess* I had been using.
And laid them down on the kitchen floor so I could see how a slate floor would look next to hardwoods.
This is what a floor looks like after vinyl has been torn off
and an attempt at sanding off the glue. Kind of burnt looking!
Finding these coasters confirmed my like of slate. Two bad floor slate was not made as LIGHT as these coasters. It would be a sure thing then.
