OUR TIPS

Use biocidal products with care. Read the label and product information before use.

Ready-to-use product. Before starting treatment, make sure the weather is dry enough to allow the product to work for at least 6 hours.
Application temperature: between 10 and 40°C. Product efficacy is reduced at extreme temperatures.
Do not spray in direct sunlight.
In the case of thick layers, remove greenery beforehand with a deck washer or high-pressure cleaner.
Application: spray or brush, saturating the surface to be treated. Leave on for one week, until greens, algae, etc. turn yellow and dry out completely, then wash off* naturally with wind and rain.
Debris can then be removed* by brushing or rinsing with a high-pressure cleaner to speed up the process. Repeat treatment if necessary for areas where greening persists.
For preventive action: apply to the surface to be treated, do not rinse.
Tool cleaning: with water, directly after application.

In all cases, carry out a preliminary test on an inconspicuous area to check compatibility with the substrate.
Do not dispose of residues down the drain or in the natural environment. Do not reuse empty packaging.
