Stucco is a versatile facing material that can be applied to flat or curved surfaces either inside or outside any building or structure. Stucco has great appeal as a surface finish because of its utility, low first cost, and minimum need for maintenance.
In its hardened state, plaster is a desirable facing material: hard, strong, fire-resistant, and color-retentive. Because plaster is also breathable, or able to transmit moisture vapor, water that gets behind it does not become trapped. That makes it resistant to rot and fungus. Plaster has proved to be a durable wall cover in all climates, whether wet, dry, hot, or cold.
The final appearance of the finish coat can be varied by changing the size and shape of the aggregate, using colored cement, adding pigments, changing the consistency of the finish mix, the method or equipment used for plastering, and the plasterer's skill in manipulating the finish coat.
