How to Remove Dampness from Wall & Revive Home Interiors

There are plenty of ways to give our apartment a ravishing makeover. But we prefer taking advantage of the largest open space we have-the walls. The wall almost serves as a blank canvas on which we let our imagination play. We paint it, wallpaper it, handprint it, hang murals, paintings, and photo frames on it, and even mount lights, furniture pieces, and air conditioners on it to make it look unique in every possible way. Again, the décor of the walls differ with the room type. Our living room wall looks completely different from our bedroom wall, and in each case, the wall décor reflects the person who we are- our taste, our preferences and even our mood we are mostly in. However, a statement wall loses its beauty when dampness attacks it. Soon ugly patches of moulds/ peeling/ paint popping/ deterioration begin to appear on it and it is no more capable of holding anything.
