Algae on the facade: removal of red algae and green growth

Microorganisms

1.such as fungi or algae on the facade not only look unattractive, but also damage the building fabric.

 In addition, mosses can also grow on the house wall, store water and thus cause mould in the long term.

2.In addition, energy efficiency decreases with damp walls, as the wetness draws heat energy out of the wall to evaporate and thus cools it down.

3.Whether fungi, mosses, red algae or other infestations – the solution for your house clearly consists of removing the algae and other growth, followed by disinfection and sealing.

The facade sealing should also be carried out as a precautionary measure for new or renovated buildings.

New facade: sealing surface

With new exterior walls or masonry, you should take immediate precautions and seal the surface (seal it). Depending on the specialized construction or maintenance company, the experts have a good idea and suitable exterior wall sealing products.

It protects the exterior walls from the effects of the weather (sunlight, acid rain, salt spray, smoke, etc.) and resists moisture from rain and fog.

All in all, with our sealants and coatings, you can add breathable, waterproof and self-cleaning agents to your home's exterior, thereby increasing the value of your property.

Exterior algae infestation: How to deal with algae?The most effective way to combat algae is during sunny weather or during the summer when temperatures are warmer. In addition to green algae, brown or red algae are often found on house walls and should be removed first with a high-pressure cleaner. Especially in the case of red algae that penetrates deep into the wall, experts use a special waterproof material that does not damage the exterior wall but removes the red algae that has penetrated deep into the pores. After cleaning, the exterior of the house/masonry usually needs to be dried first. Then proceed with disinfection.

In the future, this waterproof material will not only protect against red and green algae, but also other microorganisms such as bacteria, moss, lichens and fungi.

How do algae form on the facade?

Algae on the facade is an indication of clean air, but also an indication of permanently damp surfaces and thus of energy-inefficient facades.

Although thermally insulated walls are often so well insulated that the moisture does not evaporate due to the retention of heat – the heat that gets through over time is immediately consumed by the wet wall. Ergo, a dry wall is absolute necessary for modern houses and facades.

It would also deprive algae, as well as other organisms, plants and infestations, of their habitat. This is because water is the main reason for algae to form on the facade.

These are the most common conditions in which the algae (green, red, brown, etc.) can thrive:

• Permanent moisture / wetness
• Light, preferably the sun
• Carbon dioxide from the air
• Mineral materials from plaster / facade
• Temperatures from 0°C to 40°C

Where do infections occur most often?

Walls, brickwork and facades become infested particularly quickly and frequently with green algae, red algae, mosses, lichens and other organisms if they point north but still receive enough (reflected) light.

This is because north-facing walls are severely dry or completely dry – they simply don’t get enough sunlight. Only in the summer, when high temperatures, low precipitation, and warm winds come together, are these walls likely to dry out. But most green and red algae survived this time. That’s why it’s so important to permanently prevent an algae infestation. In particular, sealing with special waterproofing materials is essential to prevent new moisture.

Summary of steps to target algae infectionsAlgae infestation on exterior walls or masonry is not only unsightly but also harmful to building materials. Therefore, algae on exterior walls should be removed. The same applies to fungi, lichens and mosses, which can also form under well-insulated conditions, but on permanently damp surfaces. These steps (best performed by an expert) will help you fight an algae infestation: Exterior cleaning to remove algaeSurface waterproof, providing deep, long-lasting protectionSeal with Aibier&YC1 for permanent drying
