KEIM Renovation and Dehumidifying Renders

MOISTURE AND SALTS CAN

MOISTURE AND SALTS CAN DESTROY THE BUILDING STRUCTURE. KEIM RESTORATION AND DEHUMIDIFYING RENDERS ARE THE REMEDY FOR THAT.

k e i m reno va t i o n and dehumidifying renders 3 SUSTAINABLE RENOVATION ® WITH KEIM POROSAN AND ® KEIM SECCOPOR DAMAGES TO THE BUILDING STRUCTURE Rain, frost, wind, and condensation problems. Buildings are exposed to severe weather and environmental influences which can lead to severe damage to the structure. Due to a variety of causes moisture can penetrate the masonry. With the entering moisture, harmful salts such as nitrates, chlorides and sulphates are dissolved and transported. When the water evaporates, the salts recrystallise and increase in volume. This crystallisation pressure finally leads to spalling of plaster and paint. Soaked and saltloaded masonry is characterised by numerous damages such as - Damp stains - Salt efflorerescences - Render and coating spalling SOLUTION-ORIENTED SYSTEMS These damages cause great problems, particularly, in historic buildings, old structures, basements and plinth areas. Over the long term deposits of harmful salts lead to the destruction of the render structure and surfaces and represent a massive impairment. KEIM Porosan and KEIM Seccopor provide in principle two different and adapted solutions for the individual building situation. KEIM Porosan system is ideal for high salt loads due to its pore hydrophobic property, while KEIM Seccopor system is perfect thanks to its high drying performance in the case of high moisture loads such as of masonry damaged by flooding or condensation problems. Damage patterns such as salt efflorescences and damp stains IN BRIEF: KEIM renovation and dehumidifying renders provide the perfect solution for every problem!
