FAQs
How do I apply the Jarder Patio Cleaner?
Simply pour the ready-mixed solution into a watering can or garden sprayer and apply evenly to the dry, affected surface. No dilution is required.
How long does it take to see results?
Visible results, such as moss and algae turning brown, typically appear within 2-3 days of application.
Is this product safe for pets and children?
Yes, once the treated area has completely dried, the product is safe for children and pets. Ensure thorough drying before allowing access.
What surfaces can I use this cleaner on?
It is effective on a wide range of hard garden surfaces, including patios, driveways, decking, fences, roofs, and more. It is not intended for soft or unsealed surfaces.
How long does the protection last?
The cleaner creates a barrier that helps prevent the re-growth of moss and algae for up to 6 months after application.
Do I need to rinse the surface after applying?
No, rinsing is not required. The product works by breaking down the growth, which then dissipates naturally. Rain will help wash away the residue over time.
What is the coverage of a 5L bottle?
One 5L bottle is sufficient to cover an area of up to 40 square meters.
Is the product environmentally friendly?
The product is biodegradable and has a neutral pH of 8, making it a more environmentally conscious choice compared to harsh chemicals.
Troubleshooting
Product not visibly working after 3 days
Ensure the product was applied evenly and the surface remained dry for at least 24 hours post-application. Very stubborn growth may require a second application. Check environmental conditions; efficacy can be slower in very cold temperatures.
Green growth is still present after a week
This may indicate a particularly resilient type of algae or moss, or that the coverage was not sufficient. Try applying a second coat, ensuring complete saturation of the affected area. Allow another 3-5 days for results.
Product has splashed onto plants
Immediately rinse the affected plants thoroughly with plenty of water. While the product is biodegradable, direct contact with sensitive plants should be avoided.
Surface still looks stained after moss/algae has disappeared
The product is designed to kill and remove organic growth. Deep-set stains from pollutants, dirt, or long-term damage may require a different cleaning method (e.g., a specific stain remover or mechanical cleaning) once the biological growth is gone.
