If you want to change the wall paint in one of the rooms, there’s nothing wrong with doing it yourself with your family on the weekend or with the help of woodstock painters. But even if this work is left to the masons, it’s a good idea to know good painting techniques so that you can supervise the craftsmen who work. Knowing this technique is important so that the painting results are not defective. Here are some wall paint problems, one of the causes is because the painting process is not done properly https://www.onemanandabrush.com.
Foam formation and craters and eyelets occur when bubbles burst on the film during the painting and drying process. It is caused by incomplete stirring; old use of low-quality or water-based paints; the use of old rolls and brushes, the application is too fast; application of satin/glossy paint over a porous surface. Avoid using rolls/brushes that are not suitable or have been used repeatedly. Apply glossy paint using a short roll. First, coat the porous surface using the right primer. Sand the problematic part first before repainting it. The problem of fading gloss. The paint luster fades due to the painting being done in very humid conditions; the paint is too thick, causing it to wrinkle and fade the gloss; error in thinner selection. Sand the surface of the wall first. Repaint by avoiding the above conditions.
The fungus appears in the form of black, gray, or brown spots. In general, fungus forms in areas that are damp, have poor ventilation, or receive little sunlight; pre-existing mold is not cleaned before painting. Do a test to distinguish mold/mildew from dirt by applying some bleach solution (bleaching). If they disappear, the black spots are probably fungus. Remove all mold from the surface with the anti-fungal solution provided by the paint manufacturer. Use a high-quality primer before applying the final paint. Use of a paint that is too thin; use of low-quality paint tools; use of paint in a lighter color than the medium; poor paint mixing; and the surface of the substrate to be painted is too porous. Dilute the paint as directed (as written on the paint can), stir the paint until smooth, use primer before finishing.
