Use a wheel cutter to shave off excess material.

For best results, the use of metal guides is suggested, always checking that they are lined up correctly.

After removing the metal guides, use a thin brush to flatten the rabbet between the pieces of the covering material..

After the whole surface is finished and everything has dried out, apply a layer of varnish on the whole surface.

Start applying the material at the corners of the surface to be covered and then move towards the sides.

After putting all stones in place, clean and varnish the whole surface.
