Description
Gyproc RhinoBoard MoistureResistant is a gypsum plasterboard with water-repellent additives in the gypsum core and paper liners. It is engineered for use in wet or humid internal spaces (up to approximately 70% humidity) and can serve as a base for tiling or as wall lining in bathrooms, kitchens, wet areas or other moisture-exposed interiors.

Application Instructions
- Use in internal walls, partitions or ceiling-lining systems in wet or humid areas (bathrooms, kitchens, utility rooms).
- Can serve as a base for tiles — ideal where tiling is planned instead of skim-coat or paint.
- Install on appropriate stud framing or framing systems recommended by Gyproc for moisture-resistant drywall systems.
- Use standard plasterboard fixing accessories (screws, joint tape/compound) as per Gyproc guidelines; finishing depends on final surface (tile, paint, plaster).
- Avoid external exposure or continuous water immersion — suitable only for internal wet/damp environments with controlled humidity.
Suitable Applications
- Bathrooms, shower rooms (non-immersive), toilets
- Kitchens and utility rooms
- Laundry rooms or wet-area partitions
- Internal walls in humid climates or high-moisture zones
- Wet-area wall linings where tiling is planned
Compatibility & Limitations
- Compatible with Gyproc moisture-resistant drywall/partition systems (with suitable framing and fixtures)
- Non-load-bearing — not for structural walls
- Not suitable for external walls or areas with continuous water exposure (e.g. external facades, swimming pools)
- Fixings must follow manufacturer guidelines to maintain moisture resistance and structural integrity
Safety & Handling
- Store boards flat on dry, level supports before installation — protect from water and damp until fixed.
- Handle with care — lift from long edge to avoid bending or breaking edges.
- Wear protective gloves and dust mask when cutting or drilling.
- Ensure joints and edges are sealed properly to preserve moisture resistance and prevent moisture ingress.
Frequently Asked Questions
RhinoBoard MoistureResistant is used for interior walls or partitions in water-exposed or humid areas like bathrooms, kitchens, utility rooms or laundry spaces. Its water-repellent core ensures better durability than standard plasterboard under damp conditions.
Yes. This board is designed as a suitable base for tiling in wet zones—provided it is fixed correctly and joints are sealed. It’s often used where ceramic tiles or waterproof finishes are applied.
Gyproc MoistureResistant boards come in two thicknesses: 12.5 mm and 15 mm, giving flexibility based on project needs.
It is primarily intended for walls/partitions and wet-area linings. Ceilings exposed to water or high humidity can be risky — better to consult project design, preferred for walls.
Yes — MoistureResistant boards offer the same fire safety as regular gypsum boards when installed per system guidelines, making them safe for internal wet rooms and partitions.
Yes. Installation methods are similar to standard drywall — the board is fixed on stud frames, joints taped and sealed. However, ensure correct framing and sealing for moist zones.
No. It’s intended for internal use only. External walls, direct rain exposure or immersion aren’t recommended with MoistureResistant board.
RhinoBoard MoistureResistant is rated for internal environments with humidity up to approximately 70%, making it suitable for bathrooms and kitchens.
While slightly more expensive than standard plasterboard, its advantages — water resistance, suitability for wet zones, and avoiding water-damage issues — often make it cost-effective for kitchens, bathrooms or humid climates.
Use it when walls or partitions will be exposed to humidity, steam or potential water splashes — especially in bathrooms, kitchens, laundry rooms or any wet-area finishing. For dry interiors, standard boards may suffice.
