Why Mold Appears in Your Home and How to Prevent It: Tips from Polifarb
Mold is more than just unsightly black or green spots on walls — it’s a living fungus that can seriously affect your family’s health and damage building materials. Mold spores are almost always present in the air, but they only start to grow under specific conditions. In this article, we’ll cover the main reasons mold appears and practical ways to prevent it — with a focus on Polifarb solutions that help maintain a clean, healthy indoor environment.
Main Causes of Mold Growth
Mold needs just three things to thrive: moisture, suitable temperature (between +5 °C and +25 °C), and an organic food source (wood, paper, wallpaper paste, dust). Without moisture, growth is impossible — that’s why excess humidity is the primary trigger. Here are the most common sources of the problem:
High indoor humidity (above 60–70%) The number one cause. Moist air condenses on cold surfaces (walls, windows, corners), creating the perfect breeding ground. Bathrooms, kitchens, basements, and corner apartments suffer the most.
Poor or no ventilation Without regular air exchange, humid air stagnates. Closed plastic windows without airing, blocked vents, furniture pushed right against walls — all of these prevent circulation and promote dampness.
Leaks and condensation Dripping pipes, leaking roofs, poor foundation waterproofing, condensation on windows due to thermal bridges or incorrectly installed double-glazed units.
Everyday habits Drying laundry indoors, having many houseplants, aquariums, frequent cooking without a range hood, storing wet clothes — all add extra moisture to the air.
Construction or renovation mistakes Insufficient wall insulation, thin partitions, missing vapor barriers, use of low-quality materials — mold often appears exactly in these “wet” zones.
If mold has already appeared, simply washing it off is not enough — it will return in 2–3 weeks unless you eliminate the source of moisture.
Why Mold Is Dangerous for Health and Your Home
Health risks: Spores can trigger allergies, asthma, respiratory irritation, headaches, chronic fatigue. Children, elderly people, and those with weakened immune systems are especially vulnerable.
Material damage: Mold eats away at plaster, wallpaper, wood, paint, drywall — forcing you to redo repairs.
How to Prevent Mold: Proven Steps
Prevention is always cheaper and easier than dealing with consequences. Follow this step-by-step plan:
Control humidity levels Get a hygrometer — the ideal range is 40–60%. If it’s higher, use a dehumidifier or ventilate more frequently.
Ensure good ventilation
Install exhaust fans in bathrooms and kitchens with outdoor venting.
Air out rooms 2–3 times a day for 10–15 minutes.
Never block ventilation grilles with furniture.
Eliminate moisture sources
Fix leaks immediately.
Wipe condensation from windows and walls.
Dry laundry on the balcony or outdoors.
Choose the right materials and coatings Polifarb offers effective solutions designed specifically to fight moisture and mold:
Lacrysil sanitary acrylic sealants — contain powerful antiseptics and fungicides, reliably protecting joints in bathrooms, kitchens, around windows and pipes from mold and mildew. Elastic and crack-resistant over time.
Lacrysil sanitary silicone sealants — with broad-spectrum antifungal additives, perfect for wet zones (showers, sinks, toilets).
Mold-resistant paints (e.g., facade or interior lines from Polifarb with fungicidal additives) — create a surface coating that prevents fungal growth even in high-humidity conditions.
Additional measures
Insulate exterior walls and window reveals to eliminate thermal bridges.
Use dehumidifiers or heat-recovery ventilators in problem areas.
Regularly clean surfaces with antiseptic solutions.
