Concrete cleaning is something that needs to happen at least a few times a year. It is inevitable that over time, the concrete surfaces of your property will get dirty. This can happen from rain, wind bringing and settling dirt into the porous surface of the concrete, as well as chemicals and petroleum products staining it. Some other frequently seen complaints also include minor cracking and uneven settlement.
It is ideal that cracking in concrete occurs in straight lines. Control joins are the lines that are scored into the it during installation to ensure if it does eventually crack, it cracks in the right places and not randomly throughout the surface. When the cracks are minor, they can easily be fixed by a knowledgable and experienced company like Richmond Blacktop. Think of it like the perforated lines along a sheet of paper. Dirt can also settle in these areas, often worsening the situation.
Dirt & Grime
The easiest, quickest and most popular way to clean concrete surfaces or slabs is by using a pressure washer. Pressure washers use pumps to increase the pressure of the water provided by a garden hose. The high pressure water can then clean away dirt and grime that has collected in the little pockets/textured surface of the concrete. It essentially works like a compressed air pressure can used to clean computer keyboards.
There are also a number of alkali cleaning solutions available for concrete. Industrial strength alkali cleaners break down and remove soil, grease and oil from the surface. This solution can be used with a pressure washer or a stiff-bristle, outdoor broom.
Sealcoating the Concrete Surface
After cleaning your concrete surfaces, you want to apply a high quality concrete sealer. Sealcoating provides a protective layer over the concrete and stop dirt, oils, water and chemicals from making direct contact with it. This will also make cleaning a breeze the next time around as everything will have remained in the surface, rather than being engrained within the texture of the concrete.
As mentioned before, a simple stiff broom and a cleaning solution will do for your residential property, especially if it is a small surface area. For commercial and industrial properties, however, it is vital that you seek professional advice in concrete cleaning. An experienced company like Richmond Blacktop can direct you towards which products and methods would the best for your property, and the most safe.
