Bring your Indian sandstone back to life with Stone King — this powerful cleaner is specially formulated to revive the natural colour of faded sandstone and make slippery surfaces safe again.
Pressure washing no longer giving you the results your sandstone needs? Over time, Indian sandstone loses its colour and pressure washing becomes less effective against stubborn organic staining. You no longer have to regret laying indian sandstone that once brightened up your property.
A patio cleaner that is perfect for sandstone patios that are five years old or younger. A less concentrated version of our Remover for Natural Stone.
Deep cleaning action that breaks down dirt, lichen, white spots and algae.
Revives natural colour and brightens up your home.
Makes surfaces safer by removing green slippery buildup
Works wonders on all types of Sandstone, York Stone, Limestone, Marble & Travertine
Most of our customers report that Stone King makes pressure washing three times faster. It does the heavy lifting before you even pick up the hose.
To apply Stone King, you’ll need:
A pressure washer to rinse it off
Simply spray, wait, wash off!
Stone King sandstone patio cleaner is suitable for use in the garden and pet friendly. We recommend, as a precaution, keeping pets off the area until the sandstone cleaner has been washed off, making it immediately safe for pets to walk on.
1. Prepare Your Sprayer
Pour Stone King into a 5–7 litre pump-up garden sprayer.
2. Test a Small Area First
Spray a small test patch (1m x 1m), saturating the surface thoroughly.
3. Wait and Watch
If enough Stone King has been applied, you’ll see a colour change within 15 minutes.
4. Let It Work
Leave the product on for 2 hours to allow deep cleaning action.
5. Rinse Off
Lightly pressure wash the area.
6. Repeat if Needed
If any organic staining remains, simply retreat the area until it’s gone.
7. Treat the Rest of the Area
Now that you’ve seen the results, you’re ready to treat the rest of the surface with confidence.
1. Use neat – DO NOT DILUTE – Pour our solution into a pneumatic garden sprayer. (A ‘Hozelock’ 5L or 7L sprayer is recommend. Do not use a hand sprayer.) Pressurise the sprayer.
2. Apply the product to a dry surface, as a fine mist and saturate the surface.
3. If you have not used the product before. Treat just one slab first. The older the stone, the more treatments it will require. The product will remove every single last spot. By completing one slab first, this will give you an indication of how many treatments your stone will require. Only when you have removed all the black spots from the first slab, continue with the rest of the area.
4. DO NOT EXCEED THE MAXIMUM RECOMMENDED COVERAGE OF 5 SQM PER EACH 1L OF PRODUCT.
5. Once applied, allow to cure for a period of 2 hours.
6. Remove using a pressure washer, ideally with a minimum flow of 7 litres per minute. Use the fan jet attachment to sweep the dirt away. Other attachments such as circular spinning attachments will not give you the best results.
7. Any black spots that remain, simply retreat (when the surface is dry) allow to cure for 1 hour then wash off.
8. Repeat this process until no black spots remain.
9. Apply the Patio Black Spot Preventer 12 months later. Do not seal the patio.
Exceeding the recommended coverage rate will reduce the performance of this product. Coverage will vary depending on surface porosity and profile, e.g when treating sloping areas or riven surface, beware of surface run off and retreat as necessary to ensure correct coverage.
The Patio Black Spot Remover is quickly and readily biodegradable. The effluent if washed into soil, flower beds or lawn will breakdown rapidly. This product will not affect surrounding lawns or foliage in diluted state. Keep animals and unprotected persons off the treated area until dry.
Ensure product doesn’t come into contact with skin, eyes or respiratory tract. In the event product does comes into direct contact with the body, immediately rinse with water. Ensure this product does not come into contact with fabrics or furnishings.
