Crystal Cote Floor Finish is an amazing product. Floor should be cleaned of surface dirt and rinsed before application. Allow the floor to dry. Then, with a mop or applicator, apply in a thin, even coat. A single coat is generally all that is necessary. Buffing at this point is not needed or desirable.
Most dirt and marks remain on the surface and can be easily removed with a treated dust mop or damp mop. Scuff marks and ground-in soil can be removed by buffing with fine steel wool or a synthetic polishing pad.
