Painting a wall or a room yourself is certainly a feasible project to tackle. While it’s pretty straightforward, there are some drawbacks you should know in advance before you begin. There’s nothing worse than finishing a paint job just to realize something has gone wrong. Here are some common problems to try to avoid before you start painting.

Peeling
Peeling paint occurs on both interior and exterior walls and can occur due to moisture, high humidity, poor caulking, clogged channels, or a leaky roof. Improve your ventilation with wall vents and exhaust fans, fix sinking caulkers, loose tiles and solid gutters. Then remove the peeling paint, polish, clean, print and repaint.

Cracks, scales, lumps
Cracks, flaking and agglomeration can occur on all surfaces and can be caused by insufficient surface preparation. To repair, you can remove cracked paint, polish, clean, print, and repaint problem areas.

Bubble
Bubbles in paint occur due to heat and humidity. For painted surfaces that are exposed to direct sunlight or freshly dried latex paint that is exposed to rain, dew, and high humidity, you may begin to notice bubbles and blisters. The bubble bursts to see what the source of the problem is. If it is damp, be sure to fix the source of the problem, then remove the paint, gently wipe, clean, print, and repaint.

Alligator
The alligator is the pattern that can be seen to look like an alligator skin that can start as wrinkles and turn into rectangular cracks. This happens when the paint goes through weather fluctuations and tends to happen more with oil-based paints. To fix, you can scrape, polish, chemically remove, or use a heat gun. Once you have finished removing it, rinse it and let it dry completely. Then print, wait for it to dry and repaint.

Plaster
Gypsum is what happens when you see a fine, white dust forming on the painted walls, which happens in sunny, arid climates. This usually happens when exposed to weather changes. You can remove it completely by treating it with a TSP solution and then rinsing it off. Wait until it is completely dry and repaint with high quality exterior paint.
