How to Remove and Prevent Mould Outdoors

If there is mould on the surface to be treated, WOODCARE.GUIDE Mould Wash should be used instead of normal cleaning to remove mould, algae, moss, and dirt from the surface as well as possible.

WOODCARE.GUIDE Mould Wash is suitable for wood, concrete, and stone surfaces outdoors. The treatment does not remove or fade the paint surface.

After the treatment, it is worth assessing, especially in the case of wood, whether it is time for a new protective treatment using, for example, WOODCARE.GUIDE Wood Oil.

What causes mould?

Mould is formed especially in humid conditions ideal for mould spores, where spores and organisms can grow and spread on good growing surfaces, such as porous unprotected wood, brick, or stone surfaces. In Finnish conditions, for example, a mild winter means a long humid season before summer, when mould, algae, and moss growth are typically found more often in the yard.

How can I avoid mould?

It is practically impossible to completely avoid mould, algae, or moss. However, it can be prevented best by treating wood surfaces with, for example, WOODCARE.GUIDE Wood Oil, a new generation’s woodcare products such as SiOO:X Wood Treatment, or porous stone surfaces, for example, with a protective agent based on SurfaPore C nanotechnology.

Please note that no matter how good and effective the preservative was, without cleaning the dirt accumulating on the surface serves as a growing place for mould, algae, and moss. Although, properly protected surface makes it impossible for plant population or weather changes to cause damage to the protected material since the disadvantages do not reach the wood deeper than the surface. This makes cleaning easy and the service life of the material is long-lasting instead of few years.
