In the case of an extremely absorbent facade, it is necessary to apply a primer prior to applying the final finish.
Before applying a new surface finish, apply a special Baumit MultiPrimer coat and then apply a new high quality facade paint.
Applying of the basic coat Baumit MultiPrimer.
Coat by a new facade paint Baumit StarColor, NanoporColor, SilikonColor.
We will need a Baumit MultiPrimer primer, a paint roller, a container, a facade roller, or equipment for machine facade painting to compensate for substrate absorption.
The surface of the facade must be firm and cohesive, free of algae and cracks. Brush or pressure wash the dusty and dirty facade. Remove any peeling parts. If the facade still has other deficiencies, it is necessary to remove them first.
See: Render preparation
Depending on the absorbency of the render, dilute the primer with water 1:1 to 1:5 and mix well.
Apply the primer using a brush, a roller, or spray. When applying multiple layers, always apply to a dry layer. Curing time before applying further surface finish is at least 12 hours.
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.
