Concrete is one of the most durable surface materials widely used today. Even so, a concrete sidewalk, pathway, parking lot, or driveway can take a beating from regular exposure to the elements, not to mention the various substances that can get on surfaces like this from regular use. One of the most effective ways to take concrete driveway cleaning off your to-do list is with power washing.
How Does Power Washing Work?
In broad terms, you press the nozzle and strong bursts of water (water streams) are expelled. However, there's a bit more to residential and commercial power washing than this. Pressure washers can be powered by either a gas or electric motor.
Both types of pressure washer use a pump that pressurizes water delivered via a hose. The water blasts out at up to a thousand pounds or more. You then press the spray wand to force it out as you direct it towards the area you want to clean. The high pressure water can be controlled. The higher the pressure that's released, the tougher the concrete cleaning job is.
A company with experience pressure washing concrete will know how many gallons per minute (GPM) to disperse to clean your surfaces. They'll also know how many pounds per square inch (psi) to deliver. Many pressure washers have built-in tanks. They come in handy for optional detergent use.
As for the optimal GPM and psi, it depends on the surface being cleaned, how dirty, discolored, or dingy it is, and whether or not there are unique characteristics, like stamped designs, that need to be protected. If you want to deep clean concrete, for instance, somewhere around 3,000 psi would be typically recommended.
Different spray nozzles can also be used for the attached hose. Each nozzle creates different fan patterns. Generally, a wider nozzle is best if detergents will be used during the cleaning process. A medium nozzle tends to work well for general concrete cleaning, and a narrower nozzle is good for blasting away deeper stains.
Why Consider Pressure Washing Concrete?
Driveway cleaning isn't always an easy task, especially if it's coated with oil and other substances that tend to make very noticeable stains. Commercial driveways can have even more stains because of the abundance of delivery and company vehicles that often pass over those surfaces on a regular basis.
Pressure washing offers many appealing benefits that can make it a cost-effective solution for both homeowners and business owners in Savannah, Georgia. Some of these include:
• Improved curb appeal
• A good first impression on potential clients and customers
