Whether you are looking to give your home or business a facelift with a new coat of paint, apply sealant, stain, or renovate, a thorough pressure wash is a necessary first step. In addition to making surfaces look better, it protects the integrity of the surface material and can help prevent long-term damage.
A professional will use a high-pressure washer to remove accumulated dirt, grime, moss, mildew, and more. It is important to note that power washing is dangerous, as particles dislodged by the pressure of the water can fly at great velocities and could easily strike someone in the eye or cut them on contact. This is why it’s a good idea to let a professional handle it, as they are trained in the safe operation of such tools.
The hose connects the water pump to the spray wand or nozzle, which serves as the point of delivery for the pressurized water. Different nozzles are available that allow the technician to adjust the water pressure and spray pattern according to the surface to be cleaned. The most common nozzles are the 65deg black-tipped soaping nozzle, which is used to fortify clean water with detergent to gently scrub away stubborn buildup, and the red- or white-tipped nozzles for rinsing surfaces.
Before the pressure washing process, the professional should walk around the building and inspect it for cracks or other breaches that would admit water during cleaning. Also, the nozzle should be adjusted to avoid getting too close to wooden surfaces as this can damage them and cause rot. The final step is to wait for the wood to dry completely before sealing it to help preserve and protect it. pressure wash
