Preparation before painting
If the building you are going to repaint is old, the existing paint and plaster cracks should be repaired first. It is necessary to open the plaster and paint the cracks with a trowel. After removing weak plaster and paints, these loosened areas should be plastered. After the surface of the filled cracks has dried, it should be smoothed. In addition, dust on the outer surface should be cleaned with a brush. On dusty surfaces, the paint cannot adhere to the surface and therefore you will not get the productivity from the paint.
After making the necessary plaster repairs, it's time to prepare the primer. The use of primer is also important. Because priming is essential to getting the most out of your final coat of paint and providing years of trouble-free service.

Primer paint
For the choice of primer, you need to choose a primer that matches your brand of topcoat paint. You should mix the primer you choose with water according to its technical use. Apply the primer to the cleaned and repaired wall with a roller and brush. After applying the primer to the entire outer surface, you should wait for it to dry.
When the drying time is over, it's time to paint the final coat.

Facade painting
During the application, care should be taken that the weather is not rainy and the humidity is not high.
