All About Cleaning Block Paving All About Cleaning Block Paving

Cleaning block pavement is a necessary process that every homeowner with block pavement should expect to initiate on a regular basis. Complete cleaning of these pavements should not be limited to simply cleaning the pavement surface. It should also include clearing away weeds and unwanted grass that may have grown between block joints. There are a variety to cleaning methods you can use, and by choosing one of these methods that will best fit your particular pavement, you will be assured of maintaining a more attractive block pavement.

Choosing the Right Cleaning Method and Weather


For homeowners who prefer to use chemical cleaners to clean their block pavement, they should check weather reports to ensure that cleaners applied to their pavement will not be diluted or washed away by rain before it can be effective. Wind can also be a factor. When spraying chemicals in windy conditions, these chemicals can be blown into nearby grass, shrubbery, or plants that can be damaged or even killed by the chemicals. Other methods of cleaning may be more labor intensive but will not be affected by rain or wind. You should know in advance of your cleaning project which method will best fit your individual needs.

Planning Your Project


Depending on the size of your pavement and the method you use for cleaning, it could take you a few hours or a complete weekend to complete your cleaning project. Planning in advance will allow you to finish your entire project without having to interrupt your job and clean and put away equipment a number of times. If you plan to use special equipment such as pressure sprayers or chemical sprayers, and if you will need to rent these sprayer, you should reserve them in advance.

Removing Weeds, Agae, and Moss


Before attempting to clean pavement surfaces, you should remove from block joints any weeds that have grown up. If you live in a more humid and warm climate, you may also find it necessary to remove mold, moss, and algae. A fungicide applied with a sprayer will work better for this application. Be sure to use goggles and gloves if you spray chemicals.

Removing Stains


Oil and grease stain can best be removed if they are pre-treated by applying a solution of warm water and a mild determent. After allow this solution time to dissolve oil and grease, brush the oil spots with a stiff brush, rinse the water away with a garden hose, then let the surface dry before continuing with cleaning.

Using a Jet Washer


If you plan to use a jet washer, keep in mind that it will likely loosen and blow away some of the sand in the joints between blocks. However, with the reduced work time the jet washers provide, even with the time it takes to replace this sand, using these washers are likely to reduce your overall work time. If possible, use a rotary flat head attachment that can reduce splashing, save on water consumption, and can also remove stains and debris without a need for scrubbing or using chemicals.
