Mould, green algae and black lichen stains on my patio, stone paving or walls.
The Stone Doctor recommends our “Stontex All-In-One Outdoor Cleaner” which is an acid-free cleaner that removes all types of organic stains from natural stone, concrete, tarmacadam and decking. A 5 litre bottle should be enough to clean an average 30-50 square metre area.
The Stone Doctor recommends that all natural stone, concrete and brick should be sealed once the material is clean and dry.
You have two choices:
- Our “Stontex Platinum Stone Sealer” which will last up to 5 years before you need to re-seal or
- For a permanent solution we recommend our premium sealer “Dry Treat Stain Proof”.
To work out how much sealer you will need please see our Coverage Rates.
