MOULD PREVENTION

Fintex Mould Prevention Agent

Are your walls blackened and your spirits low? Fintex Mould Wash and a narrow brush can help.

Talking about the weather is an age-old hobby for us Finns and a neutral topic to start a conversation with even a stranger. This time, the recent autumn rains aren’t mentioned because they are an easy and painless topic, but because the warm and humid autumns haven’t been entirely problem-free for homeowners. One additional nuisance, resulting from these warmer (read: more humid) autumns, is the various types of growth that spoil the appearance of houses.

Different Types of Mould Growth

Black spot mould and algae are the most common growths that appear on the wooden exterior surfaces of houses. These can be particularly unsightly and make the paintwork look worse than it actually is. The most common surface growth is black spot mould. Fortunately, it does not rot or weaken the wood; it is merely an aesthetic issue.

Exterior cladding always accumulates some dirt and dust, such as pollen. When you add a long and wet autumn, you create ideal growth conditions for black spot mould, which uses the organic matter in the dirt as its food source.

These spores can thrive even on plastic garden furniture and plastic-coated metal window sills if they are not washed and cleaned periodically.

Since mould spores are everywhere, black spots can start to appear on surfaces as soon as a few years after application. Depending on other stress factors at the construction site, wall contamination can become a constant nuisance.

Simple Water Washing Needs Frequent Repetition

These growths usually come off with just water washing, but they often return over a larger area and more frequently. If only water and mild detergent are used, washing will have to be done almost annually to keep surfaces looking good.

Fintex Mould Prevention Agent can be used to wash dirty walls. It does not contain chlorine compounds that can damage paint, glass, or aluminium. The mould prevention agent is water-based; the working solution should be diluted with water at a ratio of 1:5-1:10 before use. The agent is not rinsed off, so it remains on the wall to continue preventing future growth.

A Fintex mould prevention treatment performed before painting helps to prevent and reduce future mould problems. Even if the wood looks completely clean, it almost certainly already contains some spores. Once these spores receive the moisture and nutrients they need, they begin to grow and produce more spores, which then appear as black spots on the surface.
