Rissfester Mörtel vs. Putzmörtel: Was ist der Unterschied?

Erstellt 05.16

Crack-resistant mortar is specially formulated to withstand deformation without cracking. It is typically made by mixing polymer emulsions, cement, sand, and additives. This type of mortar offers excellent waterproofing, durability, and resistance to impact and environmental damage, making it ideal for use with materials like polystyrene beads and glass microbeads.

Rendering mortar, on the other hand, is mainly used as a thin finish coat in insulation systems. It provides a smooth, aesthetic surface and adheres well to the base layer without peeling or cracking over time. While it doesn’t bear structural loads, its fine application makes it ideal for dry, exposed environments.

In summary, the main differences lie in their uses, flexibility, and application thickness. Crack-resistant mortar is applied thicker and prevents structural cracks, while rendering mortar is more flexible and designed for a smooth, decorative finish.
