How to clean block paving

No matter which block paving product you go for, some degree of maintenance will be required in order to keep your paving looking its best

Without it, the area will start to age and deteriorate. When it comes to protecting your block paving, being pro-active is better than being re-active. Even just some regular sweeping will go a long way to ensure that the build-up of dirt and detritus is kept to a minimum and preventing weed growths or staining.

General maintenance for block paving

Soapy water

A brush and soapy water can be an extremely effective method to clean your block paving, using mechanical and chemical processes to remove more stubborn dirt and detritus. Simply pour a bucketful of the mixture onto the affected area – taking care of any beds or turf area – and use a stiff-bristled brush to rub it in. Make sure that if you use a diluted cleaning product, that there is no acid present in the ingredients as this can damage the paving.

Once you feel that you have done the job, you can hose the water and soapy residue off – again, try to avoid this spilling into any plants. If, when the area is dried, there are stains or marks remaining, simply repeat the process in these targeted areas. Also, check the joining between the blocks, as sand may have become displaced, and make sure you refill this will kiln dry sand.

Pressure washing

This is the easiest method and is efficient in removing tougher debris but care should be taken to ensure that the surface of the paving is not damaged, meaning it is best to only pressure wash annually.

As with the other methods, you must ensure that you clear the patio and sweep it of major debris. With pressure washing, you should always start with the lowest setting to reduce the risk of injury to yourself and damage to the surface and slowly increase it to a level that you feel confident with. Avoid spraying directly onto the paving, instead, keep the jet spraying at an angle to the paving and constantly move in a diagonal motion to avoid damaging the pointing and avoid overexposure.


If debris, dirt and detritus is allowed to accumulate, inevitably weeds will begin to grow as the moisture and sand between the blocks provide the perfect conditions for them. However, this is easily preventable with regular brushing, which disturbs newly emerged weeds before they are able to establish themselves – saving the need to take more drastic action. If you decide to uproot weeds using a garden tool, this will likely remove some of the sand from the joining, which will need to be replenished. Alternatively, weed-killers can be used but with caution. Always make sure that you test this on a discreet area to check for any chemical reaction it might have on the block paving product before you use it across the area.


Good quality sealants will provide protection to the block paving, resisting oil spills, stains from water-based contaminants and the natural weathering of the product – a worthwhile investment especially for high traffic areas.
