Stucco is an excellent choice for home exterior. It is made of Portland cement, lime, sand and water.

Stucco provides a hard, durable, weather-resistant outer surface to protect your home from the elements. That's\' why it is suitable for brick walls, stone masonry, etc.

However, over time, stucco exteriors can suffer small chips, fractures, stains, and fading and may need repair.
