How to pressure wash a patio: step-by-step guide
Clear your patio. Move any plants or furniture and give surfaces a good sweep. This will eliminate any risk of damage or injury from flying debris and having a clear patio will give you more uniform results.
Connect your pressure washer to your hose and turn on the tap. Pull the trigger gun, letting the water run freely (approximately 20 seconds) which will expel any air from your machine. Then connect to your mains supply and turn on.
If you're using a detergent, wet your paving first on a very light setting. Add the detergent to your pressure washer and spray onto your patio using the 'mix' or 'low' pressure setting, depending on your model. Leave for 5 – 10 minutes.
If using a vario lance, turn to a medium pressure setting to wash the detergent off. Start from one corner or edge, and work across the patio using sweeping motions.
Keep your pressure washer at a 45 degree angle, using a wide fan. Don't follow the joining lines with the water jet as this could risk forcing your paving stones apart. For a quicker clean, try using a patio cleaner which could clean the area up to 5 times faster.
Turn off your pressure washer and disconnect from the water supply. Then turn it back on, pulling the trigger gun until all of the water leaves the machine. This will reduce any risk of residual water freezing and expanding inside which could cause damage to the pump.
