1. Exterior wall paint has good weather resistance. The exterior walls of buildings need to withstand wind, rain, cold and heat changes. Ordinary paints are prone to cracking, peeling, powdering, discoloration and other phenomena when applied to walls. Exterior wall paint is a functional paint designed specifically for building exterior walls. It can effectively solve these problems and has good weather resistance. Good exterior wall paint can keep the paint layer intact for more than 20 years.

2. Exterior wall paint has good water resistance. The exterior walls of buildings are subjected to rain erosion, especially in the southern region where there is abundant rain, which tests the water resistance of the paint. Good exterior wall paint is not afraid of rain erosion all year round, and will not fall off due to rain erosion. It can still play a waterproof role when there are fine cracks on the base wall.

3. Exterior wall paint has good anti-fouling properties. The exterior walls of buildings are inevitably stained by flying layers, which affects the appearance. The walls painted with exterior wall paint are not easy to stick to dirt. Rainwater can easily wash away the stains and give you a brand new wall. Some types of exterior wall paints have better anti-fouling effects when a layer of topcoat is applied on the surface. Some exterior wall paints, such as ceramic sand paint, do not need topcoat to achieve a good self-cleaning effect. Moreover, the scratches on the exterior wall of ceramic sand paint can be wiped off with a wet rag.

4. Exterior wall paint has good decorative effect. Building exterior walls pursue beauty. At present, there are many types of exterior wall paint. If you want to create a marble and granite effect wall, you can choose real stone paint, imitation stone paint, and water-coated sand; if you want to create a single color, color matching pattern, or mixed color sand wall, you can choose ceramic sand and sand glue paint; if you want to create a three-dimensional pattern wall, you can choose roughened paint and scraped sand paint. Good exterior wall paint has good color retention and can be kept from fading for more than 10 years. Ceramic sand paint can be permanently non-fading because ceramic sand paint is made of sand calcined at 1500~3000 degrees Celsius and can never fade.
