Buildings are subject to significant environmental influences. This can cause severe damage to their structure. Moisture can get into the brickwork and bring dissolved salts with it. Damage from moisture and salt will result in visible stains, efflorescence and paint or render flaking from the surface.
The KEIM Porosan render system, in combination with water ingress prevention measures, can successfully repair damaged surfaces. The KEIM Porosan system is characterised by high water-repellence and breathability. Moisture evaporates, whilst salts can crystallise in the large open pore structure without causing damage.
KEIM Porosan is particularly suitable for use on very damp walls in historic buildings, old buildings, and basement areas.
