Even minor hairline cracks with a width of max. 0.5 mm can permanently damage the facade over time. In this case, the repair of the facade is simple.
Cracks with a width of less than 0.5 mm are covered with a special penetration coat with fibers and then converted with a new facade paint.
Apply Baumit FillPrimer bonding primer to the render to cover the hairline cracks and minor damage.
Coat by a new facade paint Baumit StarColor, NanoporColor, SilikonColor.
Assess the width of cracks in the facade The surface of the facade must be firm and cohesive, free of algae. Brush or pressure wash the dusty and dirty facade. If the facade still has other deficiencies, it is necessary to remove them first.
See: Render preparation
Prepare Baumit FillPrimer bonding primer, a new facade paint, a facade roller or equipment for machine application of the facade paint.
Sufficiently stir the bonding primer in a bucket. If necessary, e.g. during very hot weather, it is possible to add max. 5% water (max. 1 L water/25 kg bucket).
Apply Baumit FillPrimer bonding primer to the render with a roller or brush evenly without breaks. The coat will bond the cracks up to 0.5 mm in width. Curing time before application of next layers is min. 24 hrs.
We apply two layers of high quality facade paint to the clean facade. The first coat is applied diluted with 10 - 15% water. After a break of a min. of 12 hours we apply 1 to 2 coats of the facade paint as required. Allow a min. of 4 hours between each coat.
Baumit facade paint may also be applied using airless spraying. It allows fast and even application of the facade paint in a short time even on large uniform surfaces.
