FAQ
The facade of my building is covered with a highly cracked cement and lime plaster. The plasterer must have used too much cement, making the plaster too solid. Despite being cracked, the plaster does not fall off. Locally, the cracks are definitelyeasy to spot but they has stopped growing larger anymore. Can I use flexible paint to cover them?
If the cracks are smaller than 0.25 mm, you can also use Alpol AF 685 flexible silicone paint. Good vapour permeability is its additional advantage. If the cracks are larger, the only solution is to use Alpol AF 645 highly flexible acrylic paint. Cracks of more than 1.2 mm in width are to be locally fixed, i.e. widened (grooved) and filled with cement and lime mortar, e.g. AZ 130 or AZ 135.
