1. Clean dust, dirt and salts from all surfaces.
2. Cover the surfaces that you do not wish to paint.
3. Clean mouldy surfaces, surfaces covered with lichen, etc., using a cleaning agent solution in a direction from bottom to top. Rinse the surface with water.
4. Putty the open cracks level with the surrounding surface, using the same composition of mortar as for the initial plaster. The plaster drying and hardening time is affected by the plaster composition used (proportion of lime and cement), air temperature, air humidity and the thickness of the plaster layer.
5. Prime the surfaces using the “wet on wet” method, using a solution of primer and water (1:1).
6. Paint the surface with a mixture of façade paint and primer (2:1).
7. Paint the surface once with façade paint.
8. Let the surface dry at least for a full 24 hours before painting it again.
9. Clean the tools with water.
