Does anti condensation paint work?
Once applied to your walls, our anti condensation paint prevents condensation by creating a thermal barrier and controlling heat flow so moisture from saturated air won’t form condensation on walls. Find out more about anti condensation paint.
What causes condensation in a bathroom?
What causes condensation? Condensation occurs when hot, moist air hits cold, dry air. This meeting causes water droplets to form on the cold surfaces (like your walls). This kind of moisture is what you’ll find on the bathroom walls after a super-hot shower.

Why do basement walls crack?
Shifting soils create a lot of pressure on basement walls, causing them to bow, buckle or crack. These cracks, combined with wet soil around the foundation, are the perfect entry point for moisture and can easily create damp walls after heavy rain storms.
How do you know if you have too much moisture in your house?
Here are a few common signs that you have too much moisture in your home: Peeling paint or wallpaper. Water marks or staining. Wet spots on ceiling after rain. Water running down inside walls. Walls that feel damp to the touch. Visible mold. A musty, stale odor.
How does rising damp occur?
Rising damp occurs when moisture is pulled upward through porous materials by capillary action. Set the edge of a paper towel in liquid — the liquid sort of “crawls” up the towel. Building materials like plaster and drywall can act like that paper towel, bringing moisture into your walls from the ground.
What causes a leak in a bathtub?
The most obvious cause of leaks are plumbing problems. Almost every homeowner’s dealt with a leaky bathtub or sink. Also common are issues with water-wielding appliances — washing machines and dishwashers are often the culprit.
Dew Point
In all cases the root cause is because a surface has reached the “dew point” level aka where the surface is cool enough to allow condensation to form. Below is a chart many use to find out when this will happen & it is called a psychometric chart.
Fix A – lower the humidity level
For years many have heard, keep your house between 40 to 60% relative humidity. In cold climates this advice causes many to add in humidifiers to help keep the air inside the house at that level. So with that if you look at the red line, it is sitting at 75° with 60% humidity – in this case any surface at 60° is now a condensing surface.
Fix B – Raise the Surface Temperature
As you can see, controlling humidity levels can only get you so far – this is an infrared shot of the window above when the outdoor temps were just dipping into the negative values – indoor temperature 68° with a humidity level of 26% – yep it shows why there is not only water but ice forming there.
So what about the walls?
Whether it is an interior wall or an exterior wall, the general catch is why is that one area cooler than the others? In many cases it could be a penetration not sealed, missing insulation, &/or it could also be that your area requires all electric to be run via conduit creating a nice air chase.
