Water - elixir and origin of all life can cause serious damage when it reaches undesired places. As much as humans, animals and plants need life giving water, they are also under threat when water is able to attack the very substance of buildings. Moist structures not only promote the growth of algae, mould and other micro-organisms, they are also greatly affected by frost damage and unsightly efflorescence on the building surface which becomes visible through the leaching of minerals.
The capillary water absorption of water based coatings applied to building façades is a key problem. Water that penetrates through the pores and capillaries of the façade into lower areas can cause expensive damage. The permanent influence of moisture results in increased algae and mould growth, as well as the obvious aesthetic damage. What is more, the building structure is irreversibly harmed within a short time. A further aspect to be considered is the reduced heat insulation of damp material. This leads to higher energy consumption during the heating period. The main objective is therefore to reduce the water absorption of façade coatings to a minimum, without negatively affecting porosity and breathability. Living in dry houses means healthy living. With its Silsan® products, Graf & Co. GmbH has committed itself to this aim. Silicone water repellent additives and impregnating agants, based on functionally modified silicones, help to keep buildings dry. The active ingredient which provides the water repellency is able to cover the sides of the pores and capillaries completely, making them water repellent without sealing them. Thereby, the breathability of the material remains intact and the natural moisture level of the building structure is kept well balanced.
