Maintenance of facades and roofs

The maintenance of facades and roofs requires dealing with the proliferation of lichens, mosses, algae and fungi. Many organisms are capable of growing on the exterior surfaces of houses. A biocidal treatment will provide long-term protection for the façade or roof, but sooner or later the passage of time will alter the surfaces, dirt will settle and act as an anchor for the development of lichens and mosses. It will then be necessary to renovate the facade or roof with a treatment with ORGANCIDE QC 50.

The treatment of facades and roofs will be done after removal of as many deposits as possible by brushing with water. The treatment must be carried out in dry weather.

L’ORGANCIDE QC 50 is used at a concentration of 5% in water. The effectiveness of the treatment can be checked with the naked eye. After treatment, lichens and mosses turn brown and disappear.
