One of the questions potential driveway owners want to know when they call our company is: What is the pressure washing cleaning process? Whether you are hoping to give it a go yourself or bring in a professional to help you.
We believe that understanding the process is key to achieving and maintaining a clean and tidy driveway.
What does a pressure washer do?
In its most basic sense, a pressure washer uses cold water and the power of an electric motor to release a stream of water, usually at a force of around 230 bar, onto your target area. Pressure washers are effective at removing dirt, debris and moss and algae, lichen; with the most common uses including:
– Block driveway paving
– Concrete driveways
– Oil stains
– Graffiti removal
– Chewing gum removal
– Exterior building cleaning
– Cleaning patio slabs
– Tarmac driveway
– Front entrance stairs and walkways
– Wood decks
– Garage floors
– Home exteriors that are vinyl or brick
– Cars and Trucks
What are the essential tools you will need?
A professional power cleaner will arrive on your doorstep with their pressure washer, a softwash pre-treatment chemical mix, a hypo softwash mix, kiln-dried sand and a blower.
If you are opting for a DIY pressure wash, you may not have all the treatments that a professional would have, but eco-friendly cleaning products and detergent can help remove some of the grease and stains from the surface.
A step-by-step guide to pressure washing a driveway
1. Brush away or blow any debris or dirt using a large broom or backpack blower, and remove any loose plant pots or articles from the surface. You then use water in your pressure washer to ensure any loose dirt has been blasted away before beginning the clean.
2. Softwash pre-treatment sprayed all over the surface before being left to dwell for around 20 minutes.
3. It is cutting the edges, using the turbo lance fitting on the pressure washer. The high-pressure nozzle removes the dirt with ease.
4. A surface clean hot wash. You are using our hot water treatment, sitting at around 90 degrees, using a different fitting which you run over the top of the entire surface to engage the three jet Whirlaway feature and providing your deepest clean.
5. A rinse down, to remove everything that was displaced by the hot wash. Done using our cold-water jet wash again, following by the manual job of ensuring the edges of the driveway surface are clear of any debris that has been pushed around by the jet.
6. The post-softwash treatment mix, made using sodium hypochlorite, which must be correctly mixed using our Dosatron, to the correct percentage – one of the reasons why we recommend bringing in a professional when using these cleaning materials and chemicals. This wash should be applied again using the pressure washer, and then washed and rinsed away. Should then be left to dry, ideally overnight and hopefully with no interfering rain.
7. The final stages involve re-sanding any cracks or breakages in the setting around the block paving slabs. If your driveway is tarmac, this stage won’t be necessary.
Specialist kiln-fried sand should be swept all over the surface area using a large broom, making sure to reach the edges and deep into any cracks or damaged areas.
8. Finally, turn on the blower and brush away any excess sand. You have a perfectly clean driveway, ready for another summer of BBQ’s, visitors and bike rides.
If in doubt about any of these stages, simply get in touch with your local pressure cleaning company and collect some quotes.
Though doing it yourself can sometimes feel like the more cost-effective way to do manual tasks, by bringing in a professional you can be sure of an excellent finish and safe process – with a much lower chance of additional damage or accidents.
