There are some things to consider when deciding how often to power wash concrete. You may want to wait at least a year between power washing sessions to give your concrete a chance to bond and protect itself. If you must power wash concrete more often, you should follow these tips. You should avoid power washing your concrete every other week, though.
If you own a commercial property, you may want to consider power washing the concrete on a quarterly basis. If you have limited traffic, you may want to power wash your concrete every two years. If you have a residential property, power washing your concrete once or twice a year should be sufficient. Depending on the area, you may need to repeat the process as often as you wish. If you live in an area where algae and dirt accumulate, you may want to power wash more frequently.
Pressure washing the concrete can remove dirt and other debris that is hard to see. It will also get rid of any stains that have accumulated over time. Besides removing dirt and grime, it will also remove any harmful bacteria and mold that could damage your concrete. Excess moisture can also lead to the need to replace concrete. For this reason, it is important to clean your concrete at least once a year.
When power washing your concrete, it is important to use a machine with adequate pressure. You will want a power washer with a high pressure and a flow rate of at least four gallons per minute. Higher pressure will help remove heavy tire-skid marks and tougher contaminants, but most power washer contractors agree that 3000 psi will do the job most of the time. A power washer with a high water pressure will ensure that you get the best cleaning results.
If you have the money, consider renting a power washer. Pressure washing concrete is a tedious process that can take several hours. Moreover, power washing can be very dirty work and you’ll need to wear protective clothing and gloves. You will need to be careful, because the concrete wash will shoot rocks and loose material up into the air. And, power washing can become a hobby! If you’re not careful, you might end up damaging your concrete.
Another thing to consider before power washing your concrete is the area around your home. If you live in a drought area, power washing might be forbidden. Not only does power washing waste precious water resources, but it can also cause accidental damage. It can strip paint off your house, rip siding and shingles, and damage your car’s paint. It can also cause serious injuries. In such cases, you should consider the area you live in before deciding how often to power wash your concrete.
While concrete is one of the most durable building materials, it is still susceptible to wear and tear. This can result in stains and imperfections, particularly if the driveway is heavily used. A pressure washer can prevent this by delivering water 30 to 80 times stronger than a garden hose. A pressure washer will also protect your driveway by preventing water from penetrating it. If you do not want to have to spend more money on power washing, try using a water-based sealant.
