We have multiple options to get your paving back to its former glory:
New Clean 60 – a high performance patio and path outdoor cleaner which is ideal for cleaning natural stone and porcelain. After just 60 minutes, and without agitation, it will eliminate layers of grime, dirt and lichen from your stone. (Please note: this product can harm or possibly kill vegetation so try to avoid washing off onto garden or lawned areas.)
No More Black Spot – professional grade outdoor cleaner which eliminates all traces of stubborn grey/white lichen and typical patio black spot from all surfaces after 2 hours. In cases of severe black and white lichen contamination, leave the patio black spot remover to dwell overnight and power wash off the following morning. (Please note: this product can harm or possibly kill vegetation so try to avoid washing off onto garden or lawned areas.)
No More Algae – a professional grade microbiological surface biocide cleaner. No More Algae’s unique formula works by itself – apply and leave! Use annually for complete protection where any green algae appears during the year. The algae will slowly disappear after 30 days and stay away for up to a year! You do not need to wash away.
Cement Residue Remover – Effortlessly removes cement and mortar residues, rust, lime, efflorescence and other hardened dirt layers.
All natural stone has iron in it which turns to rust when:
- Exposed to the natural elements eg rain
- An acidic cleaner has been used on the paving to clean it
Rust-off can be used to to get rid of the orange rust marks. Please note: this will turn the iron bright purple. Do not leave the product on to dry as this will stain the paving purple.
As porcelain is non-porous it does not require sealing.
Even though our stone paving is very hard-wearing, we recommend that you seal it to slow down the natural weathering process and make your paving last longer. The sealant will also protect the stone against staining – this includes muddy footprints, bird droppings, wet leaves and BBQ grease.
Please note: When sealing your paving, make sure you wipe away any residual sealant within 15 minutes with a clean dry cloth as any excess will leave a cloudy patch on the paving.
There are many different sealants on the market which can make it difficult to decide which one to use. At Silverland Stone we only sell water-based impregnating sealants – this means that the sealant is absorbed into the stone and lasts longer than sealants which sit on the surface.
When deciding on a sealant:
- Do you want to change to appearance of your paving? If you prefer the look of your paving when it is wet, you can opt for a Colour Enhancing Sealant. Please note: this will enhance the colour and have a matt finish. We do not recommend any gloss finish sealants. These sealants will sit on top of your paving which may effect the anti-slip texture of your paving and will not last very long.If you do not want to change the appearance of your paving then you can use an invisible sealant.
- How long do you want it to last? Simply put: the more money you invest in your sealant, the longer it is going to last. Cheaper sealants tend to have larger molecules and do not soak into the stone as much as more expensive sealants which means they rub off quicker. Likewise with cheaper coating options: Coatings rub off over time leaving an unattractive patchy look to your paving slabs.
Before sealing your paving, allow a minimum of 6 weeks to work any natural salts out of the stone first and to see if any efflorescence appears. The longer you leave your paving before sealing, the more likely the efflorescence will have come out and the paving settled. Sealed too soon and any problems will be sealed in and very difficult to undo.
The efflorescence is natural and can be brushed away with a stiff brush. DO NOT WET THE PAVING as the salts will sink back into the stone.
