This clear topcoat is as tough as it gets. Goes on in one coat at 400-600 Sq Ft/Gal. Has an abrasion loss rating of 4mg(the lower the number the better). Do not apply thicker than 400 sf/gal to avoid bubbling. If going over an existing coating or topcoat you ust rough the surface up with 100 grit to enuse a proper bond. If using nonslip mix into can and stir contimously to avoid settling. Use a roller. Pouring the coating with nonslip directly onto the floor will result in dull spots.
