Step by step working instructions

1. What do we need?

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.

2. Facade cleaning

Vyčistenie fasády

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.

3. Primer

Depending on the absorbency of the render, dilute the primer with water 1:1 to 1:5 and mix well.

4. Product application

5. New facade coat

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.

6. Facade paint spraying
