Pressure washing is a complicated task in and of itself, but when you are trying to pressure wash concrete surfaces this complexity can become several orders of magnitude higher at any given point in time. A big part of the reason why that is the case has to do with the fact that concrete is a notoriously difficult surface to pressure wash effectively, and suffice it to say that you need to find the optimal pressure levels because anything too high might chip the surface and anything too low would let the porous material absorb far too much water in some way, shape or form.
What you need more than anything else is a good pressure washer for concrete, and obtaining one that has a relatively high PSI would be a good place to start off from. Any machine that you might use for pressure cleaning Houston concrete needs to offer at least 4,000 PSI, and 4,500 PSI might be even more beneficial because it is right at the sweet spot where the pressure is neither too high nor too low.
DeWalt has some excellent pressure washers that offer the ideal PSI for concrete, and you can’t say that you have pressure washed effectively until you use something that’s in their product line. We can’t tell you how many people are converted to the cult of DeWalt once they start using their pressure washers, and chances are that you will start to swear by this brand as well if you give these machines a try. Alternatively, you can hire a professional who would already know all about concrete pressure washing and would bring the appropriate equipment for the job.
