A variety of methods can be used to clean pavers. A leaf
blower can remove leaves and grass clippings. A garden hose with spray nozzle
can remove surface dirt. A stiff brush and a lot of elbow grease followed by
the hose and spray nozzle can remove even more dirt. And homeowners can include
a variety of cleaners. Hedberg Landscape and Masonry Supplies have 3 metro
locations where you can find a full line of do it yourself spot and general
cleaners available.
What about the pressure washer? Most pressure washers
available at the home improvement stores are over powered and under fed,
resulting in pressures that can strip the Cream Coat off of new
pavers and old. Finishing concrete and during the manufacture of pavers a Cream
Coat forms on the top surface. The surface you see (including the color)
hides what is below and that's a lot of small rocks (and not that much color).
The Paver Doctor recommends the use of hot water (160
degrees) low pressure (300-600 PSI) and high water volume (5-8 GPM) to clean
pavers. Cleaners need proper dwell, agitation and rinse. The applications must
be worked in two different directions. Glass, wood or metal siding, veneer
stone or brick and stucco must be protected from acids based cleaners.
Consideration of run off into planting beds, lawn and ultimately watersheds
will direct what chemicals can be used.
The key to cleaning stains is to do it quickly after it
happens. Reactive measures are much more
successful when a proactive approach is taken. A sealant application will
reduce stain absorption. Sealants are designed to prevent the penetration of
contaminants including dust, dirt, oil that dull the colors of pavers. Regular
maintenance cleanings become quick, easy and much less intrusive to the
colorful Cream Coat.
Dirty soiled pavers are both an appearance issue and can affect
the integrity of the paver by holding onto moisture which during freeze thaw
periods can lead to spalling. Feel free to call The Paver Doctor to assess this
or any other issues related to your pavers! We specialize in paver
