February is the month when your walls stop being polite and start being… suspicious.
One day everything looks fine. The next day you’re staring at a dark patch in the corner like it’s a crime scene. If you’ve noticed condensation stains, mould blooms, or damp patches, you’re not alone. February is basically the “reveal party” for winter wall problems.
Why February exposes the mess
All winter, your home is making moisture. Showers, cooking, drying clothes, and yes—breathing like a normal human. When warm, moist air hits a cold wall, it turns into condensation. Over time, that moisture can lead to mould and damp marks. That’s why it often shows up later in winter, not on the first chilly day.
And it’s not just an “ew” problem—damp and mould can affect health, so it’s worth tackling early. The UK Government even stresses that simply wiping visible mould isn’t enough if you don’t deal with the cause (like condensation and poor ventilation).
Step 1: Figure out what you’re dealing with
Let’s keep it simple:
1) Condensation + mould (surface problem)
- Black speckles near windows and corners
- Worse after showers/cooking
- Often shows up where air doesn’t move much (behind wardrobes, in corners)
2) Damp patches (staining that pushes through)
- Brown/yellow marks that come back
- Paint may bubble, peel, or look permanently “wet-looking”
- Usually needs a proper seal so it stops reappearing
Step 2: Do the quick “stop making it worse” routine
Before we talk paint, here are small habits that make a big difference:
- Open windows for 10 minutes daily (quick blast of fresh air, not an all-day freeze-out)
- Use extractor fans during showers and cooking
- Don’t dry laundry on radiators if you can help it
- Wipe heavy window condensation in the morning
- Leave a little space between furniture and cold outside walls
Think of it as telling moisture: “You don’t live here anymore.”
Step 3: Use the right paint for the right problem
Sometimes cleaning isn’t enough—especially when mould keeps coming back like an unwanted sequel.

A simple “do this this weekend” plan
If you want a clear plan (without 47 trips to the hardware store), do this:
- Dry the area out (ventilation + heating)
- Clean and prep: remove loose/flaking paint; wipe grime/grease
- Treat mould if present (clean it properly and let it dry fully)
- Choose your paint:
- mould spots + condensation zones → Polar Mould-Resistant Paint
- damp marks/stains pushing through → Polar Dampseal
- Apply two coats (and let it dry between coats)
The goal is simple: fix it now, so spring doesn’t turn a small patch into a full wall redo.
