Paint is used to add color to surfaces. In addition to than covering your wall or ceiling with your favourite hue, paint also provides the necessary protection from weather your wall or ceiling deserves.
How do you know if your wall needs a fresh coat of paint? Fresh paint is one of the most cost-effective choices for redecorating. But there are also times when repainting is necessary even if you aren't ready for a change of color. Here are some problems that can require you to have your wall refinished:
- Peeling. UV radiation from sunlight can cause poorly formulated paint to delaminate and eventually peel off the painted surface. This is because the resins that are supposed to hold the paint together become brittle and lose their plastic properties. Peeled off paint must be removed entirely, cleaned thoroughly, and repainted.
- Loss of color. The look of a color will depend on many factors, from the setting to the shininess or the hiding property of the paint. If the color of your wall used to be a dark royal blue and is now a pale blue resembling a cloudy sky, though, then the paint has faded and you'll want the colors freshened up.
- Chalking. Some paints chalk after being exposed to UV radiation for a long time. You can check for chalking by squeezing your thumb against the wall. If your thumb comes away with powder sticking on it, then the paint has chalked. Chalking may also coincide with a loss in color. Do not by any means put a fresh coat of paint over a chalked surface. It will have to be cleaned with soapy water and dried before reapplying fresh paint.
- Cracks. Cracked painted surfaces are also a sign of paint failure. Depending on the severity of the cracks, you may want to do a spot refinish or you may need to strip the paint to the bare surface before reapplying a fresh coat of paint.
- Moulds. Moulds are fungi and naturally occurring. They thrive in humid places. You may clean small-infected spots with soap and water. For large areas, the whole wall should be power washed and treated with a fungicide to kill the mould. You may also want to coat it with a state-approved anti-fungal paint.
The paint failures described above may occur in different degrees of severity and in combinations. Have your professional painters and decorators diagnose the problem for you if you are uncertain whether or not it is time to repaint.
