The formation of mold and algae on the exterior walls of buildings is manifested by a series of concomitant factors, è in fact the presence of d& # 39 water in the wall for long periods is fundamental. This condition is possible; to verify, following long periods of continuous rain or in the case of surface condensation due to high humidityà atmospheric associated with daily temperature changes.
1. Clean all external surfaces (even those that are not contaminated) with COMBAT SOLUTION, a whitening solution containing sodium hypochlorite in aqueous solution, to be used in cycles for treating wall surfaces infested with mold and algae.
2. After a few minutes, rinse thoroughly with a low-pressure cleaner to completely eliminate all traces of the treatment.
3. Rinse and allow to dry completely. During rinsing foam is generated, continue washing until the phenomenon disappears.
4. Treat all external surfaces (even those that are not contaminated) with a BIOCID PLUS algaecide solution and fungicide spread with a brush to waste. The product inertises in depthà the support and hydrophobes the capillaryà of the existing finish.
