Cement is a versatile material that has been used in construction for centuries. It is a popular choice for building walls, floors, and other structures due to its durability and strength. However, many people are unsure whether cement can be used on exterior walls. In this article, we will explore the use of cement on exterior walls and provide a comprehensive guide on how to use it effectively.

Can You Use Cement on Exterior Walls?
The short answer is yes, cement can be used on exterior walls. However, there are several factors to consider before using it. Firstly, the type of cement used should be suitable for exterior use. Ordinary Portland cement (OPC) is not recommended for exterior walls as it is prone to cracking and water damage. Instead, a blend of OPC and pozzolanic materials such as fly ash or slag should be used. This type of cement is more resistant to water and weather damage.

Secondly, the surface of the wall should be properly prepared before applying cement. The wall should be cleaned of any dirt, debris, or loose material. Any cracks or holes should be filled with a suitable filler before applying cement. This will ensure that the cement adheres properly to the wall and does not crack or peel off.

Thirdly, the climate and weather conditions should be taken into consideration. Cement should not be applied in extreme temperatures or during rainy or humid weather. This can affect the curing process and lead to cracking or other damage.

How to Apply Cement on Exterior Walls?
Before applying cement, it is important to mix it properly. The cement should be mixed with water in the correct ratio to achieve the desired consistency. A mixer or drill with a mixing attachment can be used for this purpose.

Once the cement is mixed, it can be applied to the wall using a trowel or a plastering machine. The cement should be spread evenly and smoothed out to achieve a uniform finish. It is important to work in small sections and not let the cement dry out before smoothing it out.

After the cement has been applied, it should be left to cure for at least 24 hours. During this time, it should be protected from rain, direct sunlight, and extreme temperatures. Once the cement has cured, it can be painted or coated with a suitable finish.

Conclusion:
Cement can be used on exterior walls, but it requires proper preparation and application. The type of cement used, the surface preparation, and the weather conditions should be taken into consideration before applying cement. By following the guidelines outlined in this article, you can ensure that your exterior walls are strong, durable, and weather-resistant.
