Its super-strength formula offers excellent coverage and fast-acting results, preventing re-growth for up to six months, though it requires careful application to avoid damage to desired vegetation.

Results are typically visible within 2 to 3 days. Moss and algae will start to turn black and break down.
The protective barrier lasts up to six months. Reapplication may be needed seasonally or if re-growth occurs, depending on environmental conditions.
Yes, Jarder Spray and Leave is suitable for use on fencing to remove moss and algae. Ensure the wood is dry before application for best results.
No, rinsing is not required. The product works by drying on the surface and forming a barrier to prevent future growth.
When diluted at a 1:5 ratio, a 5L bottle provides coverage of up to 240m².
Keep pets away from the treated area until it has fully dried. Once dry, it is generally safe for pets to re-enter the area, but avoid allowing them to lick treated surfaces.
Diluting the product (1:5) is standard for general cleaning and provides maximum coverage. Using it neat (undiluted) offers a stronger, faster action for very stubborn growth but covers less area and requires more caution.
The product comes with a 1-year guarantee.
Ensure the product was applied evenly and to a dry surface. For very stubborn or old growth, a second application may be necessary, or consider using the product neat (undiluted) on a small test area first.
Check weather conditions; rainfall shortly after application can wash away the product before it takes effect. Ensure the correct dilution ratio was used, or try a stronger concentration. Direct sunlight and warm temperatures can aid effectiveness.
Accidental overspray or runoff can harm vegetation. Always protect surrounding plants with sheeting or by carefully directing application. If damage occurs, rinse the affected plants thoroughly with water immediately and monitor their recovery. Future applications should be done with extreme caution.
Always test the product on a small, hidden area of the surface before full application, especially on coloured paving or painted surfaces. If discoloration occurs, rinse the area thoroughly with water. Avoid using the product neat on sensitive materials.
