I am also trying to get information on how to do the end grain wood block flooring tiles. How thick to cut them? What kind of sub floor? What used for the grout? What about the sealer. I did hear they should be cut cross grain and sanded. What kind of sealer or oil do you use? How wide the grout lines? We are getting started on a new house and I would love to at least use this in the kitchen. Also, do you have a tile guy lay it, or a wood floor guy? Thanks!
