Moisture Resistant Gypsum Board

Moisture Resistant Boards are also known as MR board or green board. Moisture-resistant gypsum board offers better resistance against moisture than traditional drywall. It is because they come with an aerated gypsum core along with special water-repellent additives. It uses moisture-resistant paper liners to encase these cores and hold them tight. It may use as a base for wall tile in baths, showers, and other areas subject to wetting. It comes in different brand names and in a thickness of 12.5 mm. This is normally available in the market as 1830 mm by 1220 mm panels.

How do MR boards differ from regular drywall?

MR boards have special moisture-repellent additives in the gypsum core and water-resistant paper liners, reducing water absorption to less than 5%, whereas standard drywall absorbs more moisture leading to deterioration.

Can MR boards be used in wet areas like bathrooms or kitchens?

Yes, they are suitable for use in internal wet areas with periodic humidity, such as bathrooms and kitchens. However, they should not be used in areas with continuous water contact or water seepage.

What sizes and thicknesses are MR boards available in?

Typically available in 12.5 mm thickness and sizes like 1830 mm x 1220 mm or 2438 mm x 1219 mm depending on the manufacturer.

Can tiles be fixed directly over MR boards?

Yes, MR boards are often used as a base for tiling in wet areas, providing a firm and moisture-resistant substrate.

Are MR boards fire resistant?

MR boards retain the inherent fire resistance properties of gypsum boards but check specific product ratings per manufacturer.

How do MR boards contribute to healthier indoor environments?

By resisting moisture absorption, they prevent mold and mildew growth, which improves indoor air quality and reduces allergen formation.

What edge types do MR boards come with and what are their uses?

Tapered edges allow for easy joint finishing with joint compounds and tape for seamless surfaces. Square edges are used where joints are concealed or for specific finishes.
