No. well, at least not underneath! You may use a bead of yellow glue on the butt end of each plank prior to snugging up the next one. But glue, regardless of it’s chemical make-up, can trap moisture under the planks as it cures. Not good. More critically, solid wood will expand and contract seasonally – if only by a little bit. Over time, this will do one of two things – break the adhesive bond between plank and sub floor or break the plank itself. Neither are desirable outcomes. Our flooring is so well conditioned and stable that as long as your site conditions are appropriate, blind nailing through the tongue is all that’s required for any width plank.
