Product Information

Full details

The Jarder Spray & Leave Patio Cleaner is designed for homeowners seeking a powerful, no-scrub solution to eliminate green mould, moss, and algae from various outdoor surfaces. Its key benefit is the 'spray and leave' application, which requires no scrubbing or pressure washing, saving time and effort. A potential caveat is the need for pets and children to avoid treated areas until dry, due to its concentrated nature. This 5L concentrate revitalizes patios, decking, fencing, paths, and more, offering extensive coverage and preventing regrowth for up to six months.

Extended Product Information

FAQs

How long does the protection last?

Jarder Spray & Leave creates an invisible barrier that helps prevent the re-growth of moss, algae, and mould for up to six months after application.

Do I need to scrub the surface after applying?

No, the product is designed as a 'Spray and Leave' solution. No scrubbing or pressure washing is required. The active ingredients break down the organic growth.

What is the coverage of a 5L bottle?

When mixed at the recommended 1:5 ratio (concentrate to water), a 5L bottle can cover an area of up to 240m².

Is this product safe for artificial grass?

While designed for hard surfaces like patios and decking, testing on a small, inconspicuous area of artificial grass is recommended first. Avoid direct overspray onto delicate garden plants.

Can I use this on my roof?

Yes, Jarder Spray & Leave can be used on roof tiles to remove moss and algae. Ensure safe access and application methods are used when working at height.

When should I apply the cleaner?

Apply when the weather is dry and no rain is expected for at least 12-24 hours. Avoid application during frost or extreme heat.

What happens if it rains shortly after application?

Heavy rain shortly after application may reduce the product's effectiveness and the duration of its protective barrier. Ideally, allow at least 12-24 hours of dry weather for the product to work and dry onto the surface.

How does it compare to other brands?

Jarder Spray & Leave boasts 50% more active ingredient than many other brands, leading to quicker and more effective results.

Troubleshooting

Product not appearing to work

Ensure the correct mixing ratio was used and the product was applied evenly. Results can take 2-3 days to become fully visible. Reapplication may be necessary for very stubborn or extensive growth.

Uneven results on surface

This can occur if the application was not uniform. Ensure even coverage with the sprayer or watering can. Avoid overlapping excessively in some areas and missing others.

Visible residue after drying

This is rare, but if it occurs, a light rinse with water after the surface has fully dried may help. Ensure no excess product was applied initially.

Child or pet encountered treated area while wet

Remove the child or pet from the area immediately. Wash any affected skin with soap and water. Contact a veterinarian if pets show signs of distress. The product is safe once dry.
