Cement board siding is a popular material for exterior walls because it has the durability and low maintenance of fiber cement with the look of natural wood. So what makes these benefits possible? The answer lies in how this product is manufactured. Cement board siding starts as regular Portland cement, mixed with various minerals to create a strong, porous material.
One of the key components in cement board siding is fly ash, which is responsible for creating a strong matrix that eliminates large cracks and checks by filling them in with smaller ones. What’s more, fly ash also increases the amount of calcium silicate hydrate formed during the mixing process, strengthening the siding. Unlike wood, which requires routine maintenance in repainting and staining, cement board siding is naturally resistant to moisture, including saltwater. If you live near the coast, this siding will not only protect your home but be virtually maintenance-free year-round.
Because it is manufactured using Portland cement (which contains lime, which expands as it cures), this siding product requires adequate expansion joints to prevent damage and water infiltration. It also needs protected exposure to the sun because the curing process can create discoloration and embrittlement if prolonged exposure occurs. Despite its natural strength, cement board siding is still susceptible to weathering and should be preserved with a coat of masonry sealer. If you want to choose this durable siding product for your exterior walls, ensure that it is installed by experienced professionals who will do the job right the first time.
It’s also important to note that cement board siding should not be used on ceilings because it isn’t designed for overhead exposure. In addition, it is not recommended for use in any type of direct water exposure, such as a bathtub enclosure. However, cement board siding can be painted with ordinary exterior finishes to enhance its looks and protection.
In conclusion, cement board siding is an excellent choice for homeowners looking to upgrade the exterior of their homes. This product has many benefits over wood, including natural resistance to water infiltration, pest damage, corrosion, and deterioration. Ensure that experienced professionals properly install the cement board siding you choose to ensure your satisfaction. Check for a warranty and a company guarantee to protect your investment in the future, and make a check on these things before signing a contract, so you find one of the best contractors for your project.
