With time and bad weather, the painted facades do not deteriorate: traces of water flow dirty it, the paint is peeling in places and the coating can crack, crack or even peel off. This is particularly the case with the right of an external staircase, as here. It is necessary to wash, to decase, to brush the old paint and to repair the cracks or fragments of masonry. Painting will only take place after complete drying of the support.

Preparation of the facade
1. Start by dusting the wall with a brush to remove dirt and any lichen or moss that adheres to its surface.
2. Remove the paint parts that do not hold out with a wire brush.
3. Peel away the parts of paint that no longer adhere to the painter's knife (spatula). Do this on the entire wall.
4. Wash and clean the facade with the pressure washer. Do not get too close to the wall nozzle to avoid digging the plaster.
5. Open the cracks with one of the tips of a triangular scraper. For large cracks, dig a dovetail bleed.
6. Using the painter's knife (spatula), relieve cracks with exterior plaster.
7. Restore any grooving of the plaster with the wing of the painter's knife.
8. After completely drying the filling compound, sand the coating with an abrasive sponge.
Painting the facade
1. Wear protective clothing: wear a combination of painter's, gloves and goggles. Fold down the hood of the suit.
2. Deploy a tarpaulin at the foot of the wall so as not to stain the ground (here a downhill garage).
3. Open the paint can with a flat screwdriver, taking care not to damage the groove of the pot so that it can be resealed. Mix the paint with a baguette.
4. Begin by painting the peripheral areas with the round brush on about ten centimeters.
5. Carefully paint the parts that have been stripped with a flat brush.
6. Pour paint into the bin (truck). Make sure there are no lumps in the paint.
7. Load the (foam) paint roller and wring it on the grooved side of the pan or on a spin rack.
8. Paint the facade in sections of 1m². Start with vertical passes.
9. Cross the passes to spread the paint.
10. Apply at least two coats, allowing the paint to dry thoroughly between each coat.
