Concrete facade weathersealing with sealant

Sealing exterior façade joints against weather influence, such as UV, snow, wind, driving rain, etc. Also protects against the influence of various other factors, such as chemical and mechanical loads, that may eventually cause damage. The key factors that façade weathersealant needs to cope with are protection from weathering, compensation for movements of façade elements, and aesthetic appearance.

To ensure the proper size and shape of sealant in the joint and to avoid triple adhesion, a backer rod must be used.

Backer Rod PE 450 – round backer rod with closed cell structure. Highly flexible and compressible for easy installation

Sealing joints between concrete elements

For long-lasting, weatherproof joints, a special facade sealant with high movement capability must be used to compensate for deformation in the joint without losing its elasticity or adhesion.

Facade Joint Hybrid 25LM – completely weatherproof facade sealant to protect the structure from UV radiation, rain or snow, and wind. Can be overpainted with water-based paints.

An alternative product is PU-Sealant LM 825 – polyurethane sealant with high movement capability and low elastic modulus. Suitable for sealing and insulating interior and exterior surfaces.
