“Outdoor Vertical Groove Fibre Cement Wall Lining Panels” represent a modern and highly durable cladding system that achieves the popular look of traditional V-joint or “V-groove” wood paneling with the superior performance characteristics of fiber cement.
Here is a detailed breakdown of this product, its features, applications, and installation considerations.
This product is a large format sheet panel, typically 4 feet ...

This building material combines the durability and weather resistance of fiber cement with the fast, seamless installation benefits of the T&G locking system, making it an ideal subfloor for balconies, decks, verandas, and other wet-area environments.
That is a common and frustrating issue with painting any cementitious surface, including fiber cement board.
The peeling or failure of a sealer (or paint) is almost always due to a lack of proper adhesion, which can be traced back to a few key culprits:
Fiber cement is a dense, cement-based material, and ...

Magnesium Oxide (MGO) board is often referred to as a “next-generation” building panel and is an alternative to traditional drywall, cement board, and fiber cement board.
Here is a detailed overview of MGO partition board, including its properties and common uses:
MGO board is a mineral-based green building material made from a combination of magnesium oxide ...

That’s an excellent question, as the difference between “moisture-resistant” and “waterproof” is critical when choosing building materials like fiber cement board.
Here is a breakdown of the key differences:
Moisture-Resistant Fiber Cement Board
Fiber cement board, while naturally moisture-resistant, is not inherently waterproof on its own and often requires additional treatment for wet areas or exterior use.
Here are the main ways to waterproof fiber cement board, depending on the application (e.g., shower walls, exterior siding):
This is the most common application where complete waterproofing is critical, usually before ...

The primary risk associated with “free chlorides” in Magnesium Oxide (MgO) boards is accelerated corrosion of metal building components and significant moisture damage to the structure
This risk is almost exclusively tied to older formulations of MgO boards that use magnesium chloride (MgCl2) as the binding agent (known as magnesium oxychloride cement).
Key Risks of Free Chlorides
The “weeping” or “sweating” issue is a significant problem primarily associated with older-style Magnesium Chloride boards, a type of Magnesium Oxide board.
It is a process where the board draws moisture from the air, causing salty, corrosive liquid droplets to form and leak from its surface.
What Is Weeping or Sweating?
The question has already been answered with sufficient detail ...

No, MgSO4 (sulfate-based) boards and MgCl2 (chloride-based) boards generally have the same high fire rating in their initial, dry state. The difference lies in the long-term stability of that rating in real-world, high-humidity applications.
Both types of boards are built primarily on Magnesium Oxide (MgO) cement, which is inherently non-combustible
In laboratory tests, both MgSo4 and MgCl2 boards typically ...

The question of whether MgSO4 board is a structural sheathing material is complex and depends on the specific product and its code approval, but the general answer is Yes, specific, high-density MgSO4 formulations are engineered and approved for use as structural sheathing
Here is a breakdown:
