Exteriors, General

Summer is here! If you’ve not done it already, it’s about time you tackled the grime and algae winter left behind on your decking. You don’t need to be a gardening pro for this task and it will make a great deal of difference to the feel of your outdoor space.

Gone are the days of brooms, soapy water and lots and lots of elbow grease. Now it’s all about pressure washers and a little detergent to finish the job.Pressure washing your

Step 1. Ensure your patio is completely clear of furniture, pots, plants and anything else.

Step 2. Sweep any debris such as leaves, loose soil or rubbish using a broom.

Step 3. (Be sure to closely follow the instructions on your chosen pressure washer.) Connect your hosepipe and check that the water is running freely before you begin. Remove any air pockets but letting the water flow through the pressure washer. If you’re using a hose reel, this should be fully unwound and free of kinks to minimise the risk of disruption to your water flow. To connect your hose you will require two universal connectors and a tap adaptor for your garden tap.

Step 4. Connect your pressure washer to the mains electricity supply then turn it on to pressurise the system.

Step 5. Before you start cleaning your patio, you can apply detergent to the surface to help dissolve dirt and make the patio easier to clean. Some detergents also have special properties that will help reduce the build-up of dirt in the future and will also protect your surfaces from weather damage. Specific detergents are available for stone, wood and vehicles, each specifically designed to suit the task.

Step 6. You might find that some patches of your deck or patio are harder to get completely clean. Lichens and other organisms can be particularly tough to remove with a standard patio cleaner. Most pressure washers come with a rotary jet nozzle that can provide a lot more power. By switching to this lance you can ensure even the most stubborn dirt can be removed. It is important to note that the increased power of these lances means they should only be used on hard surfaces such as stone or brickwork, softer, more delicate surfaces such as wood or vehicle paintwork may be damaged if cleaned with this type of lance.
