Façade renovation - peeling paint

Sometimes it is not only a few cracks or minor damage that can be found on older façades. In the case of smaller scale render flaking and/or edge breakouts, Baumit MultiContact MC55 W can be used as a filling mortar for repair or reprofiling once the damage has been removed.

Physically remove the peeling paint and clean the façade. The resulting uneven surface will then need to be rendered and a new quality façade render applied.

The surface of the façade must be firm and cohesive, free of algae and cracks. Physically remove the peeling paint using a spatula. Brush or pressure wash the dusty and dirty façade. If the façade still has other deficiencies, it is necessary to remove them first.

3. Bonding primer

Depending on the absorbency of the render, dilute the Baumit MultiPrimer bonding primer with water 1:1 to 1:5 and mix well. Apply the primer onto the render using a brush, a roller, or spray. When applying multiple layers, always apply to a dry layer. Curing time before applying the render is at least 12 hours.

4. Façade rendering

Apply the Baumit MultiContact MC 55 W to the dry render using an anti-corrosion toothed smoother and insert the fiberglass mesh. After slight drying of the first layer, apply the second thin layer, and after sufficient drying smooth the surface with a polystyrene, felt or foam smoother. Render width 3 - 5 mm.
