Generally speaking, outdoor coatings need to have a certain resistance to wind, frost, rain, snow, sunlight and so on (waterproof, alkali resistant, ultraviolet resistance, antifreeze, anti-fading, anti-pollution, etc.), so the requirements of the raw materials selected in the formula are higher than those of interior wall coatings. Therefore, in general, interior wall paints cannot be used for exterior walls.
