How to paint exteriors wall

First of all, you need to choose the right day, not too sunny, but also sheltered from cold or rain. Optimal for these operations are the evening hours.

It is necessary to choose the best materials, not to save on equipment, but on labor. It is necessary to have a brush to prepare the wall, a scraper to remove the plaster, and the wall detached from the walls. It is very important to spotless the base that will be painted and then dry the substrate. Cracks must be removed or repaired.

The second operation is the application of an absorbent base, with the help of a brush. The corners and edges are the first things to paint, it is possible to use other shades of color always following the main one.

We then move on to the first coat of paint, to be diluted with about 10% of water, to which it is possible to add a fungicide, an anti-mold, etc. For the final coat of paint, it is recommended by the exterior painter to use a roller, transversally and longitudinally to uniform the color.

Common Condition of the Walls

Everything seems to be ready to start painting, if not for a final check, that of the surface on which you are going to operate; to proceed with the painting and obtain good results, the walls must necessarily meet certain conditions.

Absence of cracks

It is essential to intervene promptly, as even a small crack can expand and cause damage to the building (such as infiltration of water and humidity) and weaken the load-bearing structures (with the risk of collapse).

In case of cracks, repair them, apply a skin coat reinforced with glue and mesh and finish with a thick coating, or finish off and paint after applying fixative.

This is a solution that you can successfully adopt in minor cases; in the presence of deep and serious injuries, it is always better to request professional intervention, in order not to compromise the safety of the entire building.

Absence of peeling

In case of peeling, it is advisable to intervene by removing the damaged plaster, moisten the bare parts with a wet sponge and apply a mixture based on cement, lime, sand, and water, which must be kept wet for a couple of hours and, once adhered and dried, sanded to align with the old plaster still intact.

Only then can you start painting the wall.

Before working on the plaster make sure you have good dexterity and the necessary equipment, otherwise, the damage could be greater than the benefits.

Getting professional help can save you time and effort.

Absence of humidity

The exterior painter recommends that before you start painting, you also need to make sure the walls are free from mold, algae, and moss.
