Moisture content is a critical factor to consider when selecting and installing wall coverings. Different materials have varying tolerances for moisture, affecting their durability, aesthetics, and overall performance. Here is an informative guide to help you understand the moisture tolerances of common wall coverings:
Gypsum Board
- Tolerates low to moderate moisture levels (up to 15%).
- Can be used in most interior spaces, including bathrooms with proper ventilation.
Veneer Plaster
- Excellent moisture tolerance (up to 50%).
- Suitable for high-moisture areas such as showers and kitchens.
Cement Board
- Exceptional moisture tolerance (up to 100%).
- Ideal for areas with constant high moisture, such as shower stalls.
Wallpaper
- Moisture tolerance varies depending on the type of wallpaper.
- Vinyl wallpaper offers good resistance to moisture, while paper wallpaper is not moisture-resistant.
Paint
- Paint itself has a low moisture tolerance.
- Painted surfaces require a moisture-resistant primer for protection in high-moisture areas.
Tile
- Excellent moisture tolerance (up to 100%).
- Can be used in areas with high moisture, including showers and backsplashes.
Recommended Moisture Readings for Internal Walls
To ensure optimal performance of wall coverings, it is important to maintain appropriate moisture levels in internal walls. The recommended moisture readings are:
- Below 15% for most wall coverings
- Up to 50% for veneer plaster
- Up to 100% for cement board and tile
Monitoring moisture levels and selecting wall coverings with suitable moisture tolerances will help extend their lifespan, maintain their aesthetics, and prevent damage caused by excess moisture.
