  1. Medium Duty Pressure Washers – It has 2000 – 2800 PSI It is used for much tougher cleaning tasks like driveways, sidewalks, fencing, bigger decks, and washing big vehicles like Suv`s.
  2. Heavy-Duty Pressure Washers – They have a psi of 3000-4000, used for more robust tasks like the removal of tough stains from the surface. used in the cleaning of buildings, washing away graffiti, and industrial facilities.

Types Of Pressure Washing Spray Nozzles

There are various types of nozzles each designed to provide different spray patterns and pressure levels for specific cleaning tasks to get the best cleaning outcomes and don’t cause any damage to the surface.

  1. Red Nozzle = This type of nozzle operates at a 0-degree spray pattern and releases a powerful stream of water which cleans the toughest stains from a surface, but you should be very careful while using this nozzle as it may damage the surface you are cleaning if you do not know how to operate it correctly.

  5. Black Nozzle = This nozzle operates at a 65-degree spray pattern, it releases the lowest pressure stream of spray of all the nozzles and is particularly used for applying detergent, cleaning solutions, and rinsing soap.

Choosing the appropriate nozzle for pressure washing depends on several factors the surface material, the type of dirt or stain, and distance from the surface. 

Pressure Washing Terms

There are two units of measurement (PSI) and (BAR)PSI stands for pounds per square inch which determines the power of a pressure washer, which means how forcefully it’s releasing the water spray.

BAR is a metric unit of pressure. ratings of most pressure washers are in BAR. 1 bar means 14.5 psi. make sure you know these units and have proper knowledge before purchasing a pressure washer and what kind of surface you will use it on.

Let’s find out what GPM and LPM units are = Both of these units play a key role in finding the flow rate of water.

GPM = Gallons per minute 1 GPM is equivalent to 3.79

LPM (Liters Per Minute) = These units are meant to be checked continuously while doing your cleaning activity to make sure you don’t run out of water or waste it.

Pressure Washing Tips To Clean Concrete Surfaces

  2. For cleaning residential concrete surfaces, a pressure washer of 3000 PSI would do the job excellently.
  3. After pressure washing the concrete surface and still finding some stains left on that area then its because of your carelessness so be attentive and focused while cleaning the area.
  4. The pressure washing method can clean tough stains but it lacks in cleaning the small pores inside the concrete, to clean these small pores there are various detergents and cleaning solutions you can use to wash away any kind of mold, mildew, and algae.  
  5. If it is still getting hard to clean all these oily stains and rust inside the pores do some scrubbing on the surface while applying some special cleaners and chemical rust remover then after this start pressure washing this will clean the pores and surface thoroughly.
  6. Don’t use a pressure washer to remove coatings or sealers on the concrete surface as it damages the concrete surface due to its high pressure which causes etch marks in the concrete and shortens the life of that concrete surface. Instead of this use mechanical methods such as scraping, grinding, and sanding.
  7. Seal your concrete surface after cleaning it completely because sealing acts just like a shield on the concrete and keeps the dirt, liquids, oils, and other unwanted substances away from getting inside the pores that can damage the concrete. this process also increases the life of the concrete and helps in better cleaning when you pressure wash it.
