How to Protect Your Walls From Dampness and Mold. Big and Small Prevention Measures

If you have a highly humid home environment you don’t control, damp patches are bound to appear on your walls, especially in badly lit and ventilated areas, like those behind tall furniture. They don’t only look bad on your paint, but they also damage it, as well as the plaster or any other porous material they encounter. If the affected area stays moist long enough, it becomes a living environment for mold, fungus and bacteria, which form dark spots. Those are not only ugly, but also a health hazard. So knowing how to protect your walls from dampness and mold is essential to the health of your home and of its inhabitants.
