How to install slate flooring on wood floor?

If you want to install a slate subfloor on wood flooring, it (the wooden floor) should be, at least, 1 -1/4 inches thick. If not so, apply 1/2 inch thick plywood over a standard 3/4 inch thick subfloor material. Screw the 1/2 inch thick plywood to the existing subfloor spacing the screws every 8 inches on center. Apply a thin coat of water-based urethane to the final layer of plywood that will prevent swelling by stopping water from soaking into unprotected plywood. Installing one-half inch thick cement board on top of the regular 3/4 inch subfloor is a better choice if that option still remains.

Other option is to use a crack isolation fabric in between the slate and the wood flooring. These fabrics work well to offset any differential movement between the wood subfloor and the slate. Wood may expand and contract with changes in humidity. However, slate will not react to these weather changes. The fabric absorbs the differential movement between the materials.

Easy Way to Cut Slate Tile!

Slate is a soft stone and as such easy to work with. However, when you cut slate tile, there will be dust all around. It is better to cut slate with a tile saw (if you don't want to buy it, rent it from some home improvement or hardware store). Always use glasses and ear plugs while working with industrial tools, especially when cutting slate tiles as dust can go anywhere. It will be much easier when you wet the slate tile. This minimizes formation of air borne dust but is more messy than dry cutting slate tile
