- Wash the designated area with a propriety biodegradable citric acid based cleaner. It may be necessary to repeat this treatment depending on the severity of the efflorescence and localised conditions
- Chemical methods of removal should never be used on clay products.
- Wire brushes should not be used for cleaning the clay paving surface.
This first post will cover a few simple general and initial maintenance tasks that will help to prolong the life of your purchase.
Initial Block Paving Maintenance
• For the first few weeks after being laid, the joints between a block paved surface will be relatively porous. Ingress of water from rain or other sources will consolidate the jointing sand and even flush it out (particularly on sloping sites). It is important that these joints are topped up with jointing sand to prevent damage to your driveway.
General Block Paving Maintenance
• A general clean at the start of Spring with a stiff broom and a good detergent followed by the application of a proprietary weed preventative restricts the ingress of weeds between joints which can affect the long-term durability of your patio/driveway
• If you use a power washer to clean your patio/driveway, the water jet should be angled at no more than 30° to the paved surface and sprayed diagonal across the joints. Cleaning blok paving drives by using a power washer that is too powerful (we advise no more than a medium pressure) and not adhering to this advice may mark the surface of some paving materials and break up the jointing material (Re-sand and re-point any damaged joints).
• When using any cleaning product, you must ensure it is thoroughly rinsed from the surface and channelled to suitable drainage points. Once this has been done, inspect the integrity of all the paving joints, and re-sand or re-point any damaged joints as necessary.
