Interior decoration is incomplete without painted walls. Proper wall decoration will surely enhance the beautiful look of your house. We use paint because it makes our surroundings more attractive, live and vibrant. Deterioration of the paint earlier to its rated life is considered as a failure of the paint.
Several defects like blushing & blooming, patchiness, wrinkling, etc. are observed in painting, either during painting or sometimes after the painting. These defects arise due to either chemical attacks, effects of atmosphere, sunlight, heat, humidity and dust or individually or jointly deteriorating it. Among them, bittiness is one of the most common defects observed.
