All surfacing material requires a bit
of care to protect and maintain the quality of the product and the
care of concrete is no different. Care is similar to the maintenance
of granite and other natural stone surfaces. Concrete is extremely
durable, and with proper maintenance, will last the life of a home.
A few guidelines to follow...
When cleaning, use a mild,
non-abrasive cleanser applied with a washcloth or sponge. Avoid
using abrasive pads and detergents.
Use a cutting board to avoid cutting
directly onto the countertop…while it will not harm the concrete,
it may leave marks in the sealant and affect the integrity of the
Place hot pans on a potholder or
trivet. Again, it will not harm the concrete, but may affect
Clean stains with any non-abrasive
household cleanser, however, avoid using agents which contain
bleach. For best results, do not let spills linger, especially
acidic liquids such as citrus, wine and vinegar. These types of
liquids tend to erode the sealant and can potentially stain the
actual concrete. If necessary, stains can typically be
removed by light sanding and reapplying the sealant. If this
process becomes necessary, KAR Construction should be
consulted for specific instructions.
To protect the sealant and to
maintain a durable finish, paste waxing is recommended every three
to six months or as needed. Buffing the top will prolong its
life as well as increase its shine and enhance the richness of its
color. With time and use, your countertop will develop an
exquisitely warm patina.
As with all natural stone, concrete,
in it's natural unsealed state, is porous, and prone to
staining. So it needs proper sealing to protect it from
moisture and staining. A proper sealant adds resistance to oils,
acids, alcohol and most foods. Re-sealing schedules are dictated
by the "use and abuse" of the countertop...some may need it more
frequently than others. However, if proper maintenance is
adhered to, the sealant should last 4-5 years.
When re-sealing is needed, a topical
sealer can be easily applied. Then wax with a paste
wax to provide additional protection.
