A Clean Facade Is a Sign of a Healthy Home

Just as we take care of our own health, it is important to take care of the health of the home we live in. Healthy home, healthy people. It does not matter whether you live in the middle of a busy housing estate or in a house in the countryside — every facade gradually loses its original properties over time and needs to be carefully cleaned and then repainted.

A dirty facade that has seen better days is a problem not only from an aesthetic point of view but above all from a health perspective. In addition to time, dust and weather, facades are also affected by the build-up of organisms. Algae and mould also damage the facade render, causing cracks to appear, which means the render loses its protective properties. What is more, cracks grow larger over time, allowing moisture — and with it mould — to start penetrating inside.

Most panel buildings are currently covered with thermal insulation, which reduces heat loss but also prevents the natural circulation of air, thereby promoting the growth of mould and moss. A green coating then begins to form on the facade. The spores of these organisms subsequently make their way directly into your home. Mould in particular causes respiratory problems. The greatest risk is of course for the elderly and young children, who may experience more serious consequences. With prolonged exposure, mould damages the mucous membranes of the respiratory tract and irritates the eyes and skin.

The main reasons why algae and mould appear on facades:

Facade moisture
The primary condition for the formation and spread of mould and algae is a damp environment. Moisture develops mainly on the sides of the facade that do not receive sunlight and therefore do not dry out sufficiently. At night, the outer layer of the insulation system cools down, causing dew to form, which again does not have enough time to dry out during the day. Such a spot becomes ideal for the formation and spread of mould.

Poor render quality
Most manufacturers on the Czech market use older production technologies to achieve the lowest possible render prices, which then manifests in poor quality and low resistance and durability. According to the latest assessments, the thickness of the insulation layer and the type of render used are the key factors influencing the growth of algae. Umyjem to provides a quality facade coating that will give you peace of mind for several years, as we use paints known for their high durability and self-cleaning properties.

Insufficient facade maintenance
To keep a family or apartment building facade in the best possible condition for as long as possible, it needs to be maintained. If maintenance has been neglected and the facade surface is heavily soiled, simply washing it is not enough — a new coat of paint is required. The growth of mould and algae can also be triggered by poor climatic conditions, particularly in industrial areas with higher levels of smog. Without regular render maintenance, the spread of these microorganisms is faster.

With Umyjem to, we will carry out a complete analysis followed by cleaning of the facade of your building. We first remove algae and fungi using high-pressure cleaning. If the render is heavily soiled, we also apply a new facade coating to make it look like new. For facade coatings, we use paints by Kabe Farben, which offer high durability and stability, guaranteeing you protection against contamination. Since this is an investment for several years ahead, we also offer the option of a facade coating visualisation, so you can get a proper look at a specific colour selection on your building.

Before carrying out the facade washing and any coating work, our experts will visit you to carefully inspect the condition of your facade and carry out a cleaning demonstration. Since every building and its condition is individual, we will prepare a no-obligation tailored price calculation for you.

Thanks to our many years of experience and specialist facade paint production technology, we can coat any type of facade, including historic buildings.
