Can You Put Normal Plasterboard in a Bathroom?

Bathrooms are notoriously wet and humid environments, which can be harsh on building materials. Plasterboard, a popular lining material also known as drywall, is a common choice for walls and ceilings. However, not all types of plasterboard are suitable for use in bathrooms.

Regular plasterboard, also known as white or standard plasterboard, is designed for use in dry, indoor environments. It is made up of gypsum core sandwiched between two layers of paper. When exposed to moisture, the paper and gypsum can expand and soften, leading to crumbling, bubbling, and mold growth.

To ensure durability and prevent water damage in bathrooms, it is essential to use moisture-resistant plasterboard. This type of plasterboard is specifically designed to withstand the dampness and humidity of bathrooms. It features a water-repellent coating or additives that reduce moisture absorption and prevent mold growth.

### Types of Moisture-Resistant Plasterboard

There are two main types of moisture-resistant plasterboard:

1. Green Plasterboard:

* Distinctive green color, indicating its water-resistance * Gypsum core treated with water-repellent chemicals * Suitable for use in areas with moderate moisture levels, such as bathrooms without direct water exposure

2. Blue Plasterboard:

* Blue exterior paper facing * Gypsum core treated with water-repellent chemicals and impregnated with silicone * Highly moisture-resistant and suitable for use in areas with high moisture levels, such as bathrooms with direct water exposure ### When to Use Normal Plasterboard in a Bathroom

In some cases, it may be acceptable to use normal plasterboard in a bathroom if the area is well-ventilated and has limited exposure to moisture. This could include:

Wall areas above the shower or bathtub:

These areas are generally less exposed to direct water splash. *

Ceiling areas away from the shower or bathtub:

Condensation may occur, but it is unlikely to cause significant moisture buildup. *

Bathrooms with a separate shower and bathtub:

The ventilation in these bathrooms is usually better than in combined shower and bathtub areas. ### Tips for Using Non-Moisture-Resistant Plasterboard in a Bathroom

If you decide to use normal plasterboard in a bathroom, it is important to take additional precautions to protect it from moisture:

Apply a water-resistant primer:

This will create a barrier and help repel water. *

Use waterproof sealant around fixtures:

Seal around showers, bathtubs, and sinks to prevent water from seeping behind the plasterboard. *

Provide adequate ventilation:

Install a bathroom fan or open windows to remove excess moisture. ### Conclusion

Using moisture-resistant plasterboard in bathrooms is essential to prevent water damage and ensure durability. Green plasterboard is suitable for moderate moisture levels, while blue plasterboard provides high moisture-resistance. In limited cases, normal plasterboard may be used if additional precautions are taken. By choosing the appropriate type of plasterboard and following proper installation techniques, you can create a bathroom that is both functional and long-lasting.
