Do I Need to Polish a Granite Vanity Top After Cutting?

Identification

• Granite is a natural stone for a sturdy vanity countertop with a hard surface that does not crack or break easily. The stone is available in several types of finishes that include a polished or shiny surface. Polishing a granite vanity adjusts the surface appearance, but does not create a protective barrier against stains or damage.

Polishing

• A polished surface on a granite vanity countertop creates a smooth and flat finish, which is attractive for a vanity. Polishing the stone after cutting creates the shiniest of granite finish options and works well for this type of surface since you are not walking on the slick granite. While you can rent a granite polishing machine, most vanity or countertop surfaces are polished when the manufacturer or reseller cuts the stone to the desired size. The stone only needs polishing after cutting if you are the one doing the cutting at the time of installation and you want a smooth, shiny surface. Other options instead of polishing include a honed surface for a matte appearance or a brushed finish for a rough surface, which are both used on floors or high-traffic walking areas.

Maintenance

• A polished granite vanity countertop does not seal the stone against stains. While granite has a lower absorbency rating than other stones, it is possible for a stain to set in if left to dry or if it sits on the surface for an extended time. The stone does not require a polishing maintenance program, but sealing the polished surface will help repel stains from colored liquids or oily substances. Seal the stone once a year to protect your polished surface and to keep the granite looking like new for years of enjoyment. Polished granite is resistant to scratches, so there is no maintenance required to keep the polished brilliance of the surface.

Considerations

• Consider purchasing a granite vanity countertop that is cut to the desired size and has the surface already polished. It is possible to cut the countertop during the installation process and polish only the cut edge. This will save you time and effort while installing and also guarantee the top surface has an even finish with a polish put on from the manufacturer or reseller.
