Wood – How to remove the finish of hardwood flooring before installation

flooringhardwood-floorsanding

I bought 500 sq ft of used engineered hardwood flooring, about 7 inches wide. It is stained a very dark color and I'd like to sand off / remove the top layer to reveal the natural color.
Any suggestions for sanding each board before laying the floor down?

Whooaa!

It may be hardwood but it most likely - 95%+ - engineered hardwood. First 7" is not common at all for pure hardwood and would cost a fortune. Second you almost never float pure hardwood.

So let's assume it is a nice engineered floor. The wear layer on these range between 1/32nd to a 1/4" and hardly any of them can be sanded, even once. So chances are you are going to sand, get beyond the veneer and quickly move to the "plywood" type wood underneath the wear layer. You will ruin the floor quickly - and you cannot fix it.
