Polishing cultured marble
1 of 1
Sand the top lightly, then buff with a buffer and a little cleaner. Cover the walls and floor before buffing.
disappointed by how quickly
my cultured marble countertop lost its shine, so one day I
took out my auto polisher and went
at it. What a difference.
Cultured tops are made of polyester
resin with a clear topcoat
(called the gel coat). This is the
same material that's used with
fiberglass and it buffs out beautifully. Removing the faucet makes it
easier to buff the top.
First wet-sand with 1,000-grit
paper (available at auto parts
stores) to remove small, shallow
scratches and surface stains. Don't
try to remove deep scratches or
deep stains. You'll risk sanding right
through the gel coat. Rinse and dry
Next, buff with Meguiar's
Medium-Cut Cleaner or similar polishing compound (also available
at auto parts stores). The buffing
can be done by hand, but a
small power buffer is much easier.
Finally, protect the restored finish
with a coat of cultured
marble polish (available at home centers and bath specialty stores).
Follow the label directions.
