ACRYLIC-IMPREGNATED*
NON-URETHANE-COATED -
Regular maintenance routine that consists of sweeping,
vacuuming or dust-mopping.  Beyond that, their care differs significantly from most other
floor finishes:
Use a low-speed buffing machine with appropriate pad and recommended cleaning
product as necessary.  Depending on the manufacturer, different pads may be
recommended for different steps in the cleaning process.
Use recommended dust mop treatments to enhance dust mopping.
For White/bleached products, always use an untreated mop - never any water or
petroleum-based products.  The floor should be buffed with a low-speed buffer and a
recommended product specifically for white/bleached floors.  (More maintenance
will be required of white/bleached floors than other colors.)
Some manufacturers recommend that floors that have become dull be lightly
screened, to be followed up with a recommended cleaner and recommended
conditioning product.
Follow manufacturers' directions for spot-cleaning stubborn stains.  Methods include
spot sanding or screening and then applying the recommended cleaner and
conditioner.  Other methods include using mineral spirits or hydrogen peroxide and a
hand-sized piece of pad to remove the stain.
Note that recoating such floors with urethane will void the manufacturer's warranty.

URETHANE-COATED - Acrylic-impregnated floors also require routine maintenance of sweeping, vacuuming or dust-mopping, but they do not need the commercial-type
equipment recommended for non-urethane products.
Damp-mop using a cleaner recommended by urethane finish manufacturers.  Damp-
mopping with water should NOT be part of routine maintenance.
For light scratches, apply a light wax coat to the scratched area.  Deeper scratches or
damage may require spot sanding, refinishing and resealing by a hardwood floor
professional.  Some manufactures also have touch-up kits available.
