Efficiency against Algae
Micro-organisms are omnipresent in our environment and have the ability to grow
even under unfavorable conditions. Use of micro-biocides is necessary in order to
provide long-term protection against growth on surface coatings. The choice of a
suitable biocide and its optimum dosage require knowledge of the micro-organisms
that may grow.
Most important for algal growth is humidity which can be from a leaking gutter,
but also and even more importantly from condensed water, e.g. on a thermally insulated
façade. Algae are not reliant on a surface that can provide nutrients, because
they use carbon dioxide from the air as carbon source and additional salts and trace
elements from rain and dust.The picture on the left at the end of the page shows
a colony of lichen.
