Moisture is one of the biggest threats to plasterboard walls and ceilings. In areas such as bathrooms, kitchens, laundries, and coastal homes, standard plasterboard can quickly absorb humidity. Over time, this leads to swelling, mould growth, and structural deterioration, all of which can compromise the strength and appearance of your interiors.

That’s why moisture-resistant plasterboard—often referred to as wet area board or green board—is essential in any environment exposed to dampness or steam. It provides the protection your home or business needs to stay solid, safe, and stylish for the long term.


What Is Moisture-Resistant Plasterboard?

Moisture-resistant plasterboard is a specially designed product made with water-repellent additives and a durable, treated liner. Unlike standard plasterboard, it significantly reduces water absorption, preventing internal damage and helping to maintain a clean, dry, and healthy environment.

Its core is reinforced with hydrophobic (water-resistant) materials that repel moisture, while the surface liner offers extra resistance to condensation and humidity. This makes it ideal for wet areas and coastal interiors where regular plaster would quickly fail.


🏠 Common Applications

Moisture-resistant plasterboard is the go-to solution for a wide range of residential and commercial spaces:

  • Bathrooms & Ensuites – Protects walls and ceilings exposed to constant steam, splashes, and condensation.

  • Kitchens & Laundries – Prevents damage from humidity, cooking vapours, and minor water spills.

  • Coastal Homes – Withstands salty air and high humidity typical of seaside locations.

  • Basements & Utility Rooms – Keeps damp-prone areas free from rot and mould.

  • Commercial Kitchens & Washrooms – Meets compliance standards for durability and hygiene in high-moisture environments.

Key Benefits of Moisture-Resistant Plasterboard

  • Superior Humidity Protection – Prevents bubbling, sagging, and swelling in wet or humid areas.

  • Mould & Mildew Resistance – Inhibits fungal growth, promoting a healthier indoor environment.

  • Long-Lasting Durability – Extends the lifespan of your walls and ceilings compared to standard plasterboard.

  • Australian Standards Compliant – Suitable for wet area construction and compliant with AS/NZS building codes.

  • Design Flexibility – Can be finished with paint, tiles, or waterproof membranes for a polished and functional look.

  • Low Maintenance – Reduces the need for frequent repairs or replacements caused by moisture damage.


Why It’s Essential in Coastal Areas

If you live in a coastal region like the Illawarra, Shellharbour, or Wollongong, your home is constantly exposed to salty air and moisture. This environmental exposure accelerates wear and tear on regular plasterboard. Moisture-resistant solutions provide the extra protection needed to prevent corrosion, mould, and structural damage—keeping your interiors fresh, clean, and long-lasting.

At Plastrix, we specialise in installing moisture-resistant plasterboard for coastal and wet area environments. Whether you’re renovating a bathroom, building a new coastal home, or upgrading your kitchen, we ensure every surface is sealed, set, and finished to perfection.

Final Thoughts

Investing in moisture-resistant plasterboard is more than just a precaution—it’s a long-term upgrade for your property. It ensures your interiors remain strong, hygienic, and visually flawless, even under constant exposure to humidity.

By choosing professional installation and high-quality materials, you can enjoy peace of mind, better indoor air quality, and lasting results for years to come.
