What is the cement sand mortar coverage rate for rendering?

The coverage rate for cement-sand mortar used in rendering typically ranges from 12 to 15 square meters per bag of cement (approximately 25 kg) when applied at a thickness of about 10 mm. This rate can vary based on factors such as the texture of the surface, the skill of the applicator, and the specific mix design of the mortar. It's important to consider these variables for accurate calculations.
