KefaTherm Exterieur is a facade coating that provides ideal protection against algae and moss gross, dirt, and weathering.
KefaTherm Exterieur - Ideal facade protection against algae and moss
Important facts about what causes moss and algae
Many conventional facade coatings seal the surface and as a result prevent the building structure from breathing. This causes condensation on walls, moss and algae growth, moisture absorption, thermal stresses, weathering, and frost cracking. 'Over-insulated' walls also dry poorly because they essentially block out the sun's energy, while also drawing moisture into the masonry from the interior (dewpoint), dramatically increasing heating costs. KefaTherm Exterieur provides a unique solution as reliable protection against algae, moss, and condensation water damage, while doing so without hazardous chemicals. And it accomplishes this in an ingeniously simple manner: KefaTherm Exterieur takes advantage of physics, and ensures a healthy 'skin' that allows buildings to breath.
Enduring, reliable, and without environmentally hazardous substances
Prophylactic treatment of symptoms cannot be the solution, especially since the chemical substances - algaecides and fungicides - need to be water-soluble. They are incrementally washed away from the facade and travel via the soil into the drinking water . They therefore pollute the environment and present health risks - while the supposedly protective coating looses its effect and the wall soon turns green again.

Breathing deeply – the working principles of KefaTherm Exterieur
The secret in the KefaTherm Exterieur facade coating are small 'holes', e.g. microscopically small pores in the material. The unique structure increases the total surface coating more than 20,000-fold. This breaks the water down into tiny fractions, preventing it from forming droplets or collection points. Moisture quickly and easily evaporates, allowing the facade to dry completely.
KefaTherm Exterieur is healthy skin for facades
The KefaTherm Exterieur principle is ingeniously simple. Water always travels from large to small pores. KefaTherm Exterieur takes advantage of this capillary effect to draw moisture from plaster and masonry, but conversely allows heat (such as the sun's radiation) to enter. Facades dry completely without water residue in the wall. This results in dry walls any time of the year and greatly reduces heating costs compared to moist walls. KefaTherm therefore addresses the root cause of the problem. It takes advantage of physics for continuously dry surfaces and completely avoids chemical additives with limited efficacy and questionable environmental compatibility.
