Concrete surfaces such as driveways, patios, and sidewalks are prone to dirt, grime, and other environmental factors that can cause discoloration and deterioration over time. Pressure washing is a great solution to restore the original look of the concrete and prevent further damage. However, the question is, how often should you pressure wash your concrete surfaces?
Factors that Determine the Frequency of Pressure Washing
Climate and Environmental Factors
Climate and environmental factors play a significant role in determining the frequency of pressure washing your concrete surfaces. For example, if you live in an area with high humidity, your concrete surfaces will be more susceptible to mold and mildew growth, which can cause discoloration and deterioration. Similarly, if you live in an area with many trees or near the beach, your concrete surfaces will be more prone to dirt, debris, and sand accumulation.
The foot traffic on your concrete surfaces can also determine how often you should pressure wash them. If you have a lot of foot traffic, such as in commercial areas or homes with large families, your concrete surfaces will get dirtier faster and require more frequent cleaning.
Type of Concrete Surface
Different types of concrete surfaces may require additional cleaning frequencies. For instance, a driveway may need more frequent pressure washing than a patio or sidewalk due to the amount of oil and grease that can accumulate from cars.
Guidelines on How Often to Pressure Wash Concrete Surfaces
For driveways, it is recommended to pressure wash them at least once a year. However, if you live in an area with high foot or vehicle traffic or near a construction site, you may need to pressure wash your driveway more frequently.
Patios and Sidewalks
Patios and sidewalks typically require pressure washing every 1-2 years, depending on the abovementioned factors. However, if you have pets or host outdoor parties frequently, you may need to clean them more often.
Pool decks should be pressure washed at least once a year, preferably before the start of the pool season. The chlorine in the pool water can cause discoloration and deterioration of the concrete surface, so regular cleaning is necessary.
How to Pressure Wash Concrete Surfaces
Now that you know how often to pressure wash your concrete surfaces, knowing the proper technique to avoid damage is essential. Here are some tips for pressure washing concrete surfaces:
- Start by sweeping or blowing off loose dirt and debris.
- Use a detergent designed for pressure washing concrete surfaces to pre-treat the area.
- Set your pressure washer to the appropriate pressure setting. High-pressure settings can damage the concrete surface.
- Hold the pressure washer wand at a 45-degree angle and spray sweepingly.
- Rinse the surface thoroughly with clean water.
