Product description
Pre-treatment
Remove dirt, leaves, loose fungi, green algae, and similar with a stiff broom or other suitable tool. Dry, absorbent surfaces can be moistened with water about one hour before treatment to reduce consumption.
Dilution:
Thinner / cleaning agent: Water
Mixing ratio:
1:4 with water, difficult surfaces 1:2. Disinfection: 1:20 with water
Coverage: Approx. 5 m²/liter, depending on the level of dirt
Minimum application temperature: >10°C. Best effect at >+15 – 20°C
Application
Dilute Gjöco Algtvätt with water.
Apply using a low-pressure sprayer with a wide flat fan spray so that the surface becomes wet. Can also be applied with a brush. Leave to act without rinsing off. Residues are washed away by rain without requiring further work.
Algae are normally gone within a year. On roofs, the product should be applied in 2 rounds with 2–3 weeks between treatments. On facades and other vertical painted surfaces, it may be required to wash the surface with Gjöco Hustvätt for the residues to disappear completely.
Let Gjöco Algtvätt work for at least 24 hours if the surfaces are to be washed off later. Avoid treatment in strong sunlight and on frost-covered surfaces.
NOTE! Do not use a high-pressure washer on roofs. When treating delicate surfaces such as textiles, the product must not dry in and should be rinsed off. Always do a test first to see if the material can withstand the treatment. For unpaved soil surfaces next to the treated area, use an impermeable cover (or drop cloth) to prevent contamination.
The product can only be used if the weather forecast shows no rain and no wind on the day of application or at least during the first 6 hours after application.
The treatment can be repeated again after 1 year.
Usage period: Used during the period April - September
