Is powder cement smooth or rough before external wall spraying?

Hello, generally speaking, if the exterior wall paint is smooth, the labor cost will definitely be high, because the wall surface can only be leveled after careful polishing of the bottom surface. If it's matte, it's fine. If it is shiny, the flatness requirement is higher. Smooth exterior walls are generally suitable for office buildings, business hotels, high-rise apartments, airports, Chinese villas and other places, while rough exterior walls are suitable for European villas, holiday hotels, townhouses, schools and so on; Mainly depends on what kind of image and atmosphere to create. Rough exterior walls mostly reflect a kind of texture, which can be brushed, bark, sand, particles and so on. The effect is more interesting and easier to construct, and even a flaw can't be seen.
