In this post, we will discuss the different types of cement available and which one is best suited for exterior walls.

Portland cement is known for its strength and durability, making it an excellent choice for exterior walls.

2. White Cement

White cement is a type of Portland cement that is made from raw materials that are low in iron and magnesium. It is known for its aesthetic appeal and is often used for decorative purposes. However, it is not as strong as Portland cement and is not recommended for use in exterior walls.

3. Masonry Cement

5. Fiber Cement

Fiber cement is a composite material made from cement, sand, and cellulose fibers. It is known for its durability and resistance to moisture, making it an excellent choice for exterior walls. Fiber cement is also fire-resistant and insect-resistant, making it a popular choice for homes in areas prone to wildfires and termite infestations.

In conclusion, when it comes to choosing the best cement for exterior walls, Portland cement, masonry cement, and stucco cement are the most commonly used options.
