We recommend that you keep your paved area free from leaves and natural debris, as this will keep your paving clean for longer. Natural stone paving should be cleaned at least twice a year, especially in Autumn.
To clean dirt from your paving we recommend scrubbing with a stiff brush whilst using a chemical free soap with hot water. If you must use a power washer then please observe the following steps.
1. Remove loose debris
2. Test a small area first
3. The lance of the power washer should be held at no more than 30° angle and a medium pressure selected.
4. Any jointing sand that is removed must be replaced.
5. Don’t point the hose directly at the joint or grout.
2. Oil Stains
It is crucial that you act as quick as possible when you spot the oil. The sooner a stain is treated, the better chance you have of successfully removing it. Use a dry cloth or kitchen roll to absorb as much of the oil as possible by “blotting” the stain. When the excess oil has been removed spread the area with an absorbent material such as talcum powder. Leave the stain for a further 24 hours and repeat until the powder has absorbed as much of the stain as possible. If the stain persists replace a stained slab with another slab from a less prominent area. Or if this is not possible, buy a new slab in its place.
3. Heavy Staining
Proprietary cleaners are available but are mostly acid based and are therefore best avoided, as it is possible that they might damage the paving. These can be obtained from McMonagle Stone or DIY outlets. Test a small area first before an overall application and always follow the manufacturer’s instructions.
4. Weeds, Moss and Lichen
These problems are easily controlled as long as they are treated regularly. Treat as soon as they appear, regularly during a dry period in spring and autumn. Weed and grass growth need to be attacked with an appropriate weed killer. Moss, Lichen, etc need to be treated with a water-based fungicide and algaecide.
5. Sealing of Natural Stone Paving
We stock a wide range of stone sealers, which are suitable for a range of natural stone paving. We recommend that you always follow the manufacturer's instructions and check its suitability. Please be advised that applying sealant may affect the colour of the paving.
Please note: McMonagle Stone cannot be held responsible for the possible effects or damage caused by the contamination or application of some chemically based products that came in contact with the natural stone. We recommend that you source advice from professionals with experience in cleaning natural stone paving before attempting methods or products you are unfamiliar with.
