How to Install a Herringbone Floor

Once you have your slat length, measure and mark one strip, with the tongue end as waste, and cut it with a miter saw. Use a rubber mallet to dry-fit the number of strips that equal the length of the test slat—nine in our case. Butt the tongue of the test slat into the panel's end groove to make sure the slat's ends are perfectly flush with the panel's edges, as shown. If they're not, size another piece and test it again.
