Why have the facade cleaned?

Friday 25 June 2021

Façades are exposed to all kinds of (harsh) weather conditions. This causes moss and lime to form and your premises are no longer protected as they once were. Fortunately, nowadays there are various methods of cleaning your façade. Facade cleaning not only gives your facade a fresh look, but also gets rid of moisture problems and other types of contamination. This is an ideal job for in the summer.

Use of façade cleaning

Cleaning your façade is first and foremost done from an aesthetic point of view. After all, nobody likes to look at a dirty façade. But façade cleaning has much more significance than that. Facade cleaning restores the moisture-resistant function of your facade(s) and at the same time gives your home a considerable added value.

Facade cleaning: advantages

Unevenness and/or deficiencies stand out immediately
The value of your house (or other premises) increases

Cleaning methods

There are different ways to clean your façade. Depending on the type of contamination of your façade, a different cleaning method will be applied. And that is not the only factor that influences the choice of cleaning method. The substrate of the façade (plastic, slates, wood, metal, etc.) and the degree of pollution also play a major role in determining the type of façade cleaning. We will briefly discuss the most common cleaning methods below.

Steam cleaning

Steam cleaning, or cleaning under high pressure, is the cheapest form of façade cleaning because only water is used. Hot water with a temperature between 100 and 150 degrees Celsius is sprayed under high pressure against the façade(s) to remove light pollution like mosses, algae and other green deposits. Steam cleaning is the least harmful method for the walls and is therefore not only applied to houses and commercial buildings, but also to monuments. However, this method is not suitable for cleaning façades made of fine stone. The combination of high pressure and hot water could damage the porous stone and cause permanent damage.

Chemical façade cleaning

The name says it all: chemical façade cleaning uses chemical agents to remove persistent dirt from the façade(s). Think about rust, exhaust fumes or paint residue. The chemical product is applied to the façade so that the dirt can come loose. After a period of 20 to 30 minutes, the dirt and the chemical cleaning agent are rinsed off the façade with water. After the rinsing process, the polluted water is collected and recycled in order to minimise the impact on the environment. Because the façade has to dry, the result of the cleaning is usually only visible after 6 to 7 days.
