you can apply tiles, wallpaper, and paint directly onto MgO sulfate boards, but because the board is mineral-based and alkaline, there are specific “best practices” you must follow to ensure the finish doesn’t peel or crack.
Painting is the most common finish. The key is managing the board’s alkalinity and dust.
A high-quality MgO Sulfate Board (Magnesium Sulfate(MgSO4) typically does not sweat or weep, even in high-humidity environments.
This is the primary reason the “Sulfate” version was developed.1 The “sweating” phenomenon is almost exclusively a failure of the older Magnesium Chloride (MgCl2) boards
Why Chloride Boards “Sweat” (The Failure)
Traditional MgO boards use Magnesium Chloride as a binder. This salt is hygroscopic, ...

Both are high-performance building systems, but MGO offers superior non-combustibility and water resistance
Comparison Summary
MGO SIPs use Magnesium Oxide board as the exterior sheathing, which is a naturally non-combustible, mineral-based material. OSB SIPs use Oriented Strand Board (a wood composite) which is combustible.
The concept of “MGO Flexible Sheathing Sheet” refers to the thinner, lower-density versions of Magnesium Oxide (MGO) board that exhibit a surprising degree of flexibility compared to traditional, rigid building materials like thicker cement board or plywood.
While MGO board is an inherently cementitious and durable material, manufacturers engineer specific products to be flexible enough for certain applications.

Key Features of MGO Structural Floor Panels
These panels are designed specifically to carry loads and meet stringent building codes for floor/ceiling assemblies.
That is a very specific product configuration: Magnesium Oxide (MGO) Board Tongue & Groove (T&G) Exterior Horizontal Siding.
This product combines the core benefits of MGO board with a popular siding installation profile.
Product Description and Purpose
MGO board is a mineral-based cementitious building material composed mainly of Magnesium Oxide (MgO) and Magnesium Sulfate ($\text{MgSO}_4$).
A high-strength fiber cement rainscreen panel refers to a specialized, High-Density Fiber Cement (HDFC) product used as the exterior cladding in a ventilated facade system.
This material is engineered for superior architectural performance, offering exceptional durability, fire resistance, and long-term aesthetic appeal, making it ideal for commercial and high-end residential projects

The description you provided—“Matt, silk, smooth surface finish through color fiber cement board”—refers to a premium category of High-Density Fiber Cement Façade Panel specifically engineered for contemporary architectural cladding.
The combination of those terms defines the material’s two most critical features: the color consistency and the subtle sheen of the top coating.
Understanding the Finish Terms
These terms describe ...
