The exterior paint of your house is the most important component in rendering it an aesthetic appeal as well as it acts as a shield against certain elements like heat, dust, rain, etc… It’s the first thing someone notices when they are passing by your place. Naturally, wear and tear over the years degrades the exterior paint of the house, however, there are several typical issues with exterior wall paint that may happen under specific circumstances—or when the preparation or application has been less than optimal. It’s important to identify these common problems, understand the probable cause, and have these fixed quickly before it further damages your house.
- Blistering Paint – The development of tiny air bubbles or pockets beneath the paint is a clear indicator of blistering paint. This typically occurs when the paint is put in direct sunshine and dries off too soon. It’s also possible for the paint to blister when applied to a damp wall that has accumulated moisture. This can be fixed by removing the paint, letting the wall dry, and then painting over it in a dark area away from the sun.
- Chalking – This is a phenomenon where you will notice fine chalk powder film over the painted surface. While it is normal for all the painted walls to leave this kind of residue but when poor quality paint is used, there is excessive chalking that makes the paint fade quickly. You can fix this problem by treating the wall with a special solution that removes chalking, letting it dry, and then re-painting it using a high-quality paint brand like Nerolac Paints.
- Running or Sagging Paint – This problem can be identified when you notice the exterior of your house begins to look droopy and saggy, giving an illusion as if the paint is dripping. This is a typical problem associated with applying a thick or overloaded coat of paint on the walls. To fix this problem you will have to scrape off the heavy paint, smooth out the surface, and apply two thin coats of high-quality paint rather than a single heavy coat.
- Formation of Mildew – Have you noticed dark green or black patchy spots on the exterior of your home? It’s nothing but mildew, which is a kind of fungus or mold that grows on flat surfaces due to a lack of proper ventilation, and excess moisture. To avoid this, you should always check if the paint has a mildewcide additive in it.
- Paint Peeling – We frequently see instances of this issue all around us. Due to inadequate adherence, the paint begins to flake off the wall. This frequently happens when paint is applied to a moist surface or when inferior paint is used. When left addressed, paint blisters frequently develop into paint peeling.
- Efflorescence – An accumulation of salt on the wall is a defining feature of the paint issue known as efflorescence. This occurs when inadequate masonry building causes the dissolved salts of the water to surface. This issue is frequently brought on by inadequate waterproofing, which allows water to leak into the wall. The underlying brickwork issue can be fixed, and the exterior can then be painted watertight after that.
- Alligatoring – Alligatoring is the term for when the paint on a wall begins to chip and develop hexagonal scales resembling those of an alligator. This occurs when the second coat of paint is slapped on quickly after the first coat hasn’t had time to fully dry.
If you have noticed any of the above signs on the exterior walls of your house, we recommend that you should get in touch with a reputed painting contractor and have these fixed before they transpire into a bigger problem.
