Cleaning

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.
