Protection against anything a kitchen can serve up.
Filled with stylish cabinets, gleaming counters and beautiful backsplashes, the kitchen is a room where even appliances have gone from functional to sleek. But between boiling pots, your steaming dishwasher and even the espresso machine, this space can face a rainforest of moisture. Whether you’re building or remodeling your kitchen, National Gypsum’s PURPLE® products add lasting value because they resist moisture, mold and mildew. Use XP® Drywall in non-wet areas. Opt for PermaBase PLUS® Cement Board to provide a durable base behind the tile, slate and marble accents that make your kitchen shine.
What’s the difference between drywall and cement board?
Drywall is used to create the walls and ceilings in the non-wet areas of your home. While standard drywall is likely appropriate for low-activity, low-moisture spaces, PURPLE® drywall offers added benefits for areas that need it – for example, mold and moisture resistance in the bathroom or basement, sound resistance in the bedroom or nursery, or protection against car door dings and accidental holes in the garage.
Cement board – also known as backerboard – is specially designed for use in place of drywall behind tile in the wet areas in bathrooms and kitchens. It’s hard, durable, naturally moisture- and mold-resistant, and won’t rot, disintegrate or swell when exposed to water. PermaBase PLUS® Cement Board is ideal for use behind tile in showers, tubs, backsplashes and countertops, and behind exterior finishes such as thin brick, stucco and manufactured stone.
What kind of drywall should I use under kitchen or bathroom tile?
Use PermaBase PLUS® Cement Board instead of drywall under tile in the kitchen or bathroom. It’s hard, durable, naturally moisture- and mold-resistant, and won’t rot, disintegrate or swell when exposed to water, making it ideal for use behind ceramic tile, backsplashes and countertops.
Isn’t all drywall the same?
No. While all drywall is naturally fire-resistant, PURPLE® drywall is unique because it also resists moisture, mold and mildew. Most PURPLE® drywall products also stand up to scratches, scuffs, dents and sound. This means added value and peace of mind regardless of steamy showers, roughhousing kids or band practice.
All PURPLE® products have achieved GREENGUARD GOLD Certification for indoor air quality and are as easy to install and finish as standard drywall.
