The effect of water on the facades is manifested mainly through stains and runoff, but the greatest consequence is the degradation of the interior of the houses.

In addition to the natural wear of the materials, the anomalies that occur in the walls must generally be the following factors:

• Movements of the structure;
• Lack of maintenance;
• Construction deficiencies;
• Characteristics of the existing coating;

paint facades

The facade of a house must always be in good condition so that it can protect the house effectively.

A deteriorated coating that does not fulfill the function of a barrier against environmental agents can compromise the quality of the interior of the home.

Tips

• It is very important that the facades of a home are kept in good condition.
• Facades must be rehabilitated when they begin to show some type of degradation.
• Faster or slower degradation depends on various factors such as the area where the house is located and the materials used.
• Very rough area causes a much faster deterioration of the materials. It is very important that the materials are of high quality.
• The quality of the paint applied has a direct relationship with the time it takes for the surfaces to reach the state of degradation.
• The painting of a facade must be done in good weather, if there are prospects of rain do not start the work. We advise that this work only be carried out, depending on some area of ​​the country (south/north), usually between the months of May and September.
• It is not recommended to apply the paint on supports that are very hot due to sun exposure, since the paint dries too quickly and there is a risk of cracks forming.
• It is also not recommended to apply the paint when the ambient temperature is below 5°C, and when the relative humidity exceeds 80%.
• Always use high quality paint, especially outdoors. This is a golden rule.
• Cheap paint, exposed to the elements, sun, rain, etc., spoils very quickly and makes the walls of homes unprotected.

Before carrying out a painting job, it is advisable to make an assessment (more) as correct as possible of the possible problems that may exist in the walls of the room. Only in possession of a well-done diagnosis is it possible to decide on the best paint scheme to use.

When the problem is cracks, which appear in the coating but usually come from the plaster due to the need to remove the existing coating, the problem must be evaluated, treated at source and re-coated.

Whatever the situation, a comprehensive approach is always recommended, assessing the façade as a whole.
