The first step to cleaning block paving is to remove any large weeds that may be growing in joints. Once the weeds are removed, apply a fungicide to remove algae, mold and moss. It is helpful have a chemical sprayer for this application since it will cover a larger area more quickly. Be sure to use gloves and goggles when working with a chemical sprayer. Pre-treat oil stains and other stains prior to jet washing. Many people disagree with jet washing block paving since it will remove some sand from joints however; it is not that hard to reapply the sand after the cleaning project is completed. A useful tool for cleaning block paving is a rotary pressure washer head used in conjunction with a jet washer. Many tool hiring shops have both jet washers and rotary head attachments available for hire. A rotary flat surface washing head keeps water splashing to a minimum, conserves water and directs the water flow more precisely at the surface. Using a jet washer will remove smaller weeds, stains and dirt without the need to scrub or use harsh chemicals.
If the block paving had sand joints, it will be necessary to reapply kiln dried sand after washing. Purchase kiln dried sand and work into joints with a soft broom. Once the sand is reapplied, seal the block paving to prevent staining and mold and moss growth. The sealer may be applied with a roller or a sprayer.
Cleaning and sealing block paving should be repeated every few years and will keep the block paving looking neat and beautiful for many years.
