Cons of Durock Cement Board

Weight

Heavy to Handle

One of the significant drawbacks of Durock cement board is its weight. The boards can be quite heavy making them difficult to handle and install. This might require extra labour, especially when dealing with large projects.

Cost

More Expensive than Regular Drywall

Durock cement boards are generally more expensive compared to traditional drywall. Although its longevity and resistance to damage may make it a cost-effective investment in the long run, the initial cost can be higher for some budgets.

Despite their durability, Durock boards can sometimes be a bit brittle. If not handled or installed carefully, they can crack or break. Moreover, once installed, any heavy impact can cause damage to the board.

Requires Waterproofing

Additional Step in Installation

While the cement board alone is water-resistant, it’s not completely waterproof. This means it may still require a waterproofing membrane or coating to ensure complete water resistance, adding an extra step and cost to the installation process.

Difficult to Cut

Even though they can be cut with a simple utility knife, Durock cement boards require a bit of skill to cut accurately without causing damage to the board or causing injury. This might call for professional help or some level of experience to do correctly.

Myths and Misconceptions About Durock Cement Board

Durock cement board is a versatile and reliable material that is commonly used in construction and home improvement projects, particularly for walls and flooring in areas exposed to moisture. Due to its impressive properties like durability, water-resistance, and ease of use, Durock has gained a certain reputation that sometimes leads to various myths and misconceptions that can create confusion among homeowners and builders. This comprehensive discussion will debunk some of these misconceptions and clarify what Durock cement board really is.

Myth 1: Durock Cement Board is Waterproof

The Reality:

While it's true that Durock cement board is highly water-resistant, it is not fully waterproof. Unlike actual waterproof materials, water will not bounce off the surface of Durock or get repelled by it. Instead, Durock absorbs moisture but does not degrade or weaken when it does so. However, in setups where continuous exposure to water is expected, like in showers, the cement board must be sealed properly to prevent water seepage and damage over time.

Myth 2: Durock Cement Board Installation is Difficult

The Reality:

Many assume that installing Durock cement board is a tricky and complex process. However, this is not entirely true. While it might require more steps than installing ordinary drywall, it's not extraordinarily difficult. It involves cutting the board to the required dimensions, positioning it in the desired location, and securing it with screws. The process might require some learning, especially for DIY enthusiasts, but is generally manageable with basic construction skills and tools.

Myth 3: Durock Cement Boards are Unnecessary for Non-Wet Areas

The Reality:

Though it's true that Durock cement boards were designed for wet or high-moisture areas like kitchens and bathrooms, they are not limited to these areas alone. Due to their durability and fire resistance, Durock cement boards can also be used in other areas of the house that require these properties, like fireplace surrounds.

Myth 4: All Cement Boards are the Same

The Reality:

There are different brands and types of cement boards on the market, and not all of them are the same. Durock cement board, for instance, is known for its strength and superior water resistance, making it a popular choice for bathrooms and kitchens. Other brands might have different focuses, such as being more lightweight or easier to cut. Before choosing, it’s important to understand the specific needs and conditions of your project.

Myth 5: Durock Cement Boards can Replace Insulation

The Reality:

While Durock cement board does have excellent thermal resistance, it isn't specifically designed to provide insulation. It doesn't have the same properties as dedicated insulation materials like fiberglass or foam boards. Therefore, it’s not suitable to rely solely on Durock for insulation purposes.

Myth 6: Durock is Identical to Drywall

The Reality:

Although Durock cement board and drywall have similar uses, they are fundamentally different materials. Drywall, made of gypsum, is intended for dry, interior uses, while Durock, being a cement-based material, is suitable for wet conditions and exterior applications due to its resistance to moisture and mold.

The world of home improvement and construction is filled with numerous materials, each with its unique characteristics, features, and uses. Durock cement boards, notwithstanding the several misconceptions about it, remain a trustworthy and high-performing choice. Whether you are a homeowner, a contractor, or a DIY enthusiast, it's essential to understand these myths and realities to make informed choices for your projects.
