Cleaning the exteriors and roofs of a commercial building in the right way can make a big difference. Using the right pressure cleaning method eventually makes the building look a lot nicer, cleaner, and protects the delicate surfaces for years.
However, people often confuse high-pressure cleaning to be safe for all surfaces and soft pressure washing to be efficient for cleaning roofs. But in reality, choosing high-pressure, low-pressure, or soft pressure cleaning services for commercial buildings, including roofs, depends on many factors.
Understanding when to use each method depends on the type of surface, extent of cleaning, and size of surface. In this blog, we will compare each of these techniques to make your building safe and damage-free.
High-Pressure Washing
A high-pressure washing is a synonym for power washing. In this cleaning technique, professionals use a powerful pressure washer with a nozzle attached to its tip. This intends to control the angle and water force. The high force of the water coming out of the equipment is safe and convenient for office buildings, retail shops, and complexes.
If you are cleaning large surfaces to remove tough stains and grease, then a 3000 PSI – 4000 PSI is sufficient for pro-level cleaning. If possible, consider commercial pressure cleaning services to avoid using the wrong settings.
When to Use High-Pressure Washing?
Use High PSI on Concrete, Brick Surfaces, and Hard Stones:
Hard surfaces like concrete, brick, or natural stones can survive intense pressure without any problem. If your business space has sidewalks, driveways, or parking lots with these materials, you are good to choose high-pressure cleaning methods.
High Jet Removes Tough Stains:
If your building has more grease, stains, rust, or mold growing all over the exteriors and corners, then high-pressure cleaning is safe to use. However, it is wise to adjust the pressure from low to high and use a wider spray angle for even spread.
Large Commercial Areas:
If you own a large commercial building, shopping centre, or industrial complex, you must use a powerful stream of high-pressure washers. It covers large areas without much effort and transforms the dull appearance of a building into a beautiful facade.
Preparing Surfaces for Painting:
Before repainting or sealing a building, you can use jet pressure cleaning services to remove old paint and dust.
Low-Pressure Washing
As compared to power washing technique, low-pressure is gentler and safer on all surfaces. It involves a low-pressure washer, various nozzles, attachments, and eco-friendly solutions to break down the stains and dirt off the surface.
If you are cleaning commercial space which is neither too large or too small, then using this method after setting it between 500 to 1,500 PSI is ideal. If you are a beginner, it is best to take guidance from professional building washing experts.
When to Use Low-Pressure Washing?
Delicate Surfaces:
Low-pressure washing is ideal for cleaning delicate surfaces like vinyl siding, wood, stucco, and old brick. It generally cleans stains, dirt, and mould without causing any noticeable damage to the foundation.
Cleaning Roofs:
Low-pressure washing is often well known for cleaning roofs. Specifically, if your commercial space has shingle, tile, or metal roof surfaces, then having expert pressure cleaning services should not be a second thought.
Low pressure can clean these surfaces without cracking the tiles or damaging the shingles. It is also a safe practice to clean solar panels and gutters that can dent with extreme water force.
Maintaining Paint and Finishes:
If you have recently painted your deck, patio, fence, or driveway, then this technique is a better choice. High pressure can peel off the paint, so a low-pressure washer is a good investment.
Eco-Friendly Cleaning:
Professionals generally use eco-friendly products for low-pressure cleaning. If you prioritise less water usage and work on meeting sustainability goals, this will be a relevant option.
Soft Washing
Soft washing is a specialised cleaning method which is good for delicate areas even though they contain excess stains. It typically has under 500 PSI. The cleaning products in this method only break down the contaminants, so it is best to use a low pressure washer for efficient rinsing.
When to Use Soft Washing?
Extremely Sensitive Roofs:
Soft washing is one of the most efficient pressure cleaning services for mild stains and delicate surfaces. Instead of working directly over large surfaces, a soft washing technique removes dust off the stucco, asphalt shingles, or clay tiles.
Soft washing uses below 500 PSI but uses the advanced equipment for the aesthetic and safety concerns in commercial buildings.
Removing Mould and Algae:
Soft washing is highly popular for removing organic mould, mildew, and algae both from roofs panels, corners, and exteriors of a business unit.
The cleaning solutions you will use in soft washing are specifically designed to kill these natural growths and provide long-lasting cleaning solutions. Some of the best commercial roof cleaning companies use soft washing to follow roofing material manufacturers guidelines.
Protecting Older Buildings:
Soft washing is safe for old commercial premises. As these buildings have delicate surfaces, using any other method over soft washing can ruin the foundation and bring the opposite results.
Cleaning Windows and Glass:
Soft washing is also suitable for cleaning windows, glass facades, and other fragile surfaces. Particularly when low-pressure washing methods scratch, break, or damage the surface.
Final Words
We hope you liked reading this blog. As you see, each of the high-pressure, low-pressure, and soft wash practices have their strengths and weaknesses in cleaning a commercial building. Each of the high-pressure cleaning, low-pressure, and soft washing techniques are effective to remove contaminants and transform the business appearance.
If high-pressure streams are good to remove tough stains on large sizes, low settings work wonders for delicate and sealed surfaces. Softwashing is ideal for removing organic growths and hidden dirt and is safe for commercial building.
Whatever technique you are choosing for commercial building, having a professional like Exterior Clean for pressure cleaning services is a must.
