Power Washing for Best Results
Most times, there are some places too high to climb to wash and some dirt too tough to remove; that is when power washing comes in. Power washing is the use of high-pressure water sprayed by a machine to remove dust, loose paint, mud, grime, and dirt from the surfaces of objects such as vehicles, buildings, and concrete surfaces. Power washing is also referred to as pressure washing.
The mechanical pressure generated is always expressed in liters or gallons per minute and it is designed with a pump. In some cases, chemicals may be loaded into the machine for a cleaner and effective washing.
Power washing is the first essential step when preparing to paint or stain any part of a house. It is crucial that the surface to be painted be totally clean to allow paint coating to stick to the surface and prevent untimely peeling of coatings in small flakes or big chunks. As a result, power washing is an indispensable step in professional painting.
A Brief Overview of Power Washing
Power washing helps to clean and prepare the surface to be painted by removing dust, mold, mildew, pollen, and pollutants. For previously painted surfaces, power washing helps to remove chalking from the surface to be painted. Chalking is the breaking down of the paint’s skin surface due to exposure to sunlight ultraviolet rays and other elements. So, it is important to get rid of the chalked materials from the surface before painting.
Using the right pressure washing machine will ensure that the exterior surface is properly prepared for coating application. The nozzle of the pressure machine will ensure precision and that the right trajectory of water for different surfaces. Meanwhile, it must be professionally handled to prevent wand marks or etching of the surface usually caused by application of the pressure at the wrong angle.
Power Washing the Exterior
In most cases, the exterior of a building has dirt, dust, mildew, mold, and pollutants, which need to be removed before painting starts. It is not strange to find cobwebs around the building’s surfaces, cobwebs and spiders, and wasp nests will be washed away during powerwashing of the surface.
It is possible that some residues are left on the surface; so, it is the painter’s duty to remove them manually before any painting or waterproofing starts as power washing may not remove all chips or peeling. Using too much pressure at a close proximity to the surface may cause damage to the surface; so, the onus is on the professional painter to apply discretion regarding the right angle and closeness to the surface.
Finally, the remaining chips on the surface or floor can be removed by hand when they dry by scraping. After power washing, it is necessary that the painter cleans the surrounding chips and dirt cleaned from the surface through power washing.
