How to install moisture-resistant plasterboard in the bathroom

How to install moisture-resistant plasterboard

The most important part of building a bathroom is that the walls will stand up to everyday use. This goes for both brick-and-plaster walls, as well as plasterboard panels. Knauf Tanzania manufactures moisture-resistant plasterboard that is able to withstand the water and steam that occurs in the room.

By using the right materials from the start, a builder can ensure that the walls last for a long time without becoming moldy or rotten. This saves money and prevents the need for costly repair jobs in the future. Regular gypsum board is not suitable for bathroom walls or ceilings as it will soak up the water vapour and become soft. Be sure to use moisture-resistant panels instead.

Installing moisture-resistant drywall in a bathroom

The first step to installing any drywall is to ensure that the correct metal brackets and frames are used. Knauf Tanzania manufactures metal accessories that fit our drywall panels perfectly. Make sure you use Knauf metal profiles to hold the gypsum board panels in place securely. These components set up a solid foundation for a sturdy wall.

Fix the plasterboard panels to the metal profiles using screws that will not rust. Seal all the gaps between panels with jointing tape and plaster compound. Sand down these joins using fine sandpaper to ensure a smooth finish. Apply two coats of drywall sealer to the entire face of the plasterboard wall for additional moisture resistance.

If you are going to tile the walls, use lightweight tiles and a waterproof tile adhesive. This will ensure that the tiles do not fall off under the hot steam of a shower. Alternatively, you can paint the walls with a waterproof base coat and two or three layers of interior wall paint. This will also help to keep moisture at bay and prevent mold and fungus from growing on the wall.

These easy steps will allow you to build a bathroom with strong and durable walls. While plasterboard is susceptible to water damage, Knauf moisture-resistant drywall is specially designed and manufactured to remain strong in humid environments. Keep mold and mildew at bay by using Knauf accessories and applying a proper coating of drywall sealer on the panel surfaces before tiling or painting.
