How Power Washing Protects Concrete

calander Jul 28 , 2020 user-icon Nash Painting

At face value, the purpose of pressure/power washing is apparent. As its name suggests, this method offers a powerful way to clean various surfaces and features. However, when properly used, a power washer can accomplish more than merely cleaning and enhancing the appearance of the targeted surface. Power washing is actually an important step in protecting surfaces from further harm, including concrete. Let’s explore these key benefits of power washing your concrete.

Gets Deep Inside Cracks and Crevices

As a porous surface, concrete (when left bare) is easily penetrated by a number of substances in the environment, including moisture, dirt, bacteria, and fungi. Basic cleaning methods such as mopping, scrubbing, or spraying down with a hose can get rid of some of the grime resting on the concrete’s top layer, but these methods will not go deep enough into the concrete to remove whatever has made its way inside. If you want to truly clean and protect your concrete driveway, for instance, you’ll need something with more force. Power washing a concrete driveway once or twice a year is a great way to easily remove whatever gunk has built up inside the concrete.

Extends the Life of Concrete

The reason it’s so important to clean concrete on such a deep level is because when moisture, debris, and unwanted contaminants remain inside concrete for extended periods of time, they can lead to further structural damage that may eventually require significant repairs and/or replacements. Water, for instance, expands and contracts as temperatures fluctuate. When water gets stuck inside concrete and temperatures shift, it can create cracks in the concrete and widen existing ones. The presence of moisture can also lead to the growth of fungi like mold or mildew. While using a pressure washer to clean concrete does introduce some water into the material, it helps remove harmful materials inside the concrete so matters don’t worsen. In this way, power washing can prolong the concrete’s life.

Prepares the Surface for Sealing

While properly power washing protects concrete on its own, it is also a prerequisite to another protective process -- concrete sealing. Just as a house exterior should be thoroughly cleaned prior to painting, concrete surfaces need to be in pristine condition before they’re sealed. After the surface has been sufficiently washed and repaired, contractors can coat the concrete with a number of options (i.e. epoxy, urethane cement, polyurea, etc.). These sealers bond with the concrete, blocking off its natural pores to keep harmful materials from gaining entry and causing further harm.

Power Wash Responsibly

It must be said that while power washing can undoubtedly protect concrete surfaces, it can also damage them. The difference between these two outcomes has to do with knowledge, experience, and technique. If a power washer is cued to the wrong settings, contains the wrong type of detergent, and/or aimed at the wrong angle or distance, the blast can begin to erode the concrete itself, defeating the whole purpose. For this reason, it is always wise to hire professional pressure washing services to clean and protect your concrete rather than do it yourself.
