Dirt crusts disfigure a building and offers no protection for a façade. Thanks to its large inner surface, a layer of dirt is an excellent absorber of moisture and pollutants. These usually react to the underside of the incrustation and cause damage to the building, even when it is initially concealed under the crust.
The history of one of the oldest building materials used by mankind
In addition to wood, stone and plant fibres, bricks are one of the oldest building materials. Clay-like loam is mixed with sand, shaped and baked in a furnace. The first bricks were made by hand and therefore had irregular dimensions.
Desalination of natural stone and other mineral building materials with the help of compresses is a well-known technique for significantly reducing damaging salts in building structures.
The Remmers restoration mortar system was specially developed for supplementing mineral building materials or replacing these materials. Why then replace damaged bricks?
Cracks in the brickwork must be repaired, regardless of their cause. The Remmers spiral anchor system is used to connect parts of the masonry to each other simply and highly efficiently, so that the brickwork is strong again.
Joints can make up to 20 % of the overall façade. Therefore, the form and colour of the joints have a decisive impact on the appearance. Also, the joints on the building have a technical function.
Remmers anti-graffiti products belong to the class of semi-permanent graffiti removal systems. Graffiti and paint smears can be removed from treated surfaces easily thanks to the use of a high pressure water jet equipment (hygrothermal cleaning).
For preventive and sustainable protection against moss, fungi and algae, a liquid protective layer against green deposits can be applied before hydrophobing or paint. It forms a protective layer on the substrate, which only becomes active when there is damage. In this way, effective protection against green attack is guaranteed for a very long period.
Water plays a central role in the weathering of mineral building materials. One sensible (precautionary) measure to prevent damage is hydrophobization.
As an alternative to a hydrophobic agent, the water-repellence of the façade can also be achieved using a silicone resin paint or a transparent silicone resin paint. This naturally changes the character of a façade but is a highly effective and easy maintenance option, in some cases the only way, to protect masonry from moisture.
