In construction and home improvement, it’s important to prevent water damage. This is especially true in wet areas like bathrooms and basements. A material often mentioned in this context is waterproof drywall.
But how accurate is the term “waterproof drywall,” and does it truly live up to expectations? Let’s break down the reality of waterproof drywall by discussing its name, applications, and alternatives.
What is Waterproof Drywall?
In reality, the term waterproof drywall is somewhat misleading. Drywall, even those treated for moisture resistance, can never be truly waterproof. Waterproof drywall, such as greenboard or purple board, is designed to withstand moisture better than regular drywall. However, it is still susceptible to water damage. Its primary role is to minimize moisture absorption rather than prevent it entirely.
Drywall consists of absorbent materials such as gypsum and paper. To protect it from moisture, we add coatings and treatments to provide some level of protection. Greenboard is good for humid areas like bathrooms and laundry rooms, but avoid using it where there is direct water, such as in showers.
Waterproof Drywall for Bathroom
Bathrooms often get damp, causing problems like mold, peeling paint, and damage to the building’s structure. Waterproof drywall for bathroom applications typically refers to moisture-resistant options such as greenboard drywall. It works well in damp areas, but it is not fully waterproof. Therefore, you should not use it behind tiles in showers or places with a lot of water exposure.
Waterproof Drywall for Shower: A Misconception?
Waterproof drywall for shower installations is not advisable. Even with waterproofing treatments, drywall cannot withstand constant exposure to water. For shower areas, builders recommend using durable materials.
Good options include cement board or water-resistant panels. These materials won’t break down when they get wet. These materials offer superior performance in areas exposed to direct water contact, unlike drywall, which can fail over time.
Waterproof Drywall Panels: A Step in the Right Direction
Waterproof drywall panels are better than standard drywall for areas with moisture concerns but not constant water contact. These panels have a special coating that helps them resist water, making them stronger in damp areas. While these panels are a step up from conventional drywall, their performance is still limited. If water exposure persists for a long time, the material may become damaged and require replacement.
The Reality Behind Waterproof Drywall Price
The waterproof drywall price varies depending on the type of moisture-resistant drywall you choose. Greenboard and purple drywall are more expensive than standard drywall because of their enhanced water resistance. The typical price for purple drywall varies between $15 and $60 per panel, while greenboard is usually priced at approximately $14 to $18 per panel. For areas needing real waterproofing, these products might not provide enough protection. Choosing alternatives like cement board can be a better and more cost-effective solution over time.
What is Waterproof Drywall Called?
In construction, contractors often use greenboard or moisture-resistant drywall as the main type of waterproof drywall. Another variety is purple drywall, which offers better resistance to mold and mildew. These products work well in humid areas but are not waterproof for places with direct water contact.
Exploring Waterproof Drywall Alternatives
Using waterproof drywall in wet areas like bathrooms or basements is a good idea. This will help prevent damage.
Moisture can easily damage regular drywall. Waterproof drywall is more resistant to water and moisture. These materials provide greater protection against moisture and are better suited for areas exposed to water.
Cement Board
Cement board is one of the most popular alternatives to drywall in wet environments. It consists of a mixture of cement and reinforcing fibers, which makes it highly durable and water-resistant. Unlike drywall, cement board will not absorb water, nor will it degrade over time when exposed to moisture.
People frequently use it as a backing material for tiles in showers and around bathtubs. Its strength and resilience make it an excellent choice for any area prone to direct water contact.
Fiber Cement Board
Fiber cement board is another solid choice for areas where waterproofing is essential. This board, made of cement and cellulose fibers, is known for its durability and water resistance. It performs similarly to cement board but is often lighter and easier to work with. Fiber cement board is great for bathrooms, laundry rooms, and kitchens. It protects against moisture and helps stop mold and mildew from growing.
PVC Panels
For a truly waterproof option, PVC panels are an effective alternative to drywall. These panels are made of PVC, which is waterproof, making them ideal for areas with high moisture. PVC panels lock together tightly to prevent water leaks. They are commonly used in places like homes and businesses to keep out moisture. They are also low maintenance and easy to clean, making them suitable for showers, kitchens, and basements.
The Best Waterproof Drywall Option
For those searching for the best waterproof drywall, greenboard and purple drywall are the leading moisture-resistant drywall types. These products perform well in humid places like bathrooms and kitchens, but you should not expose them to direct water. However, they are still not a perfect solution for wet spaces like shower enclosures. Cement board remains the go-to choice for those environments, ensuring long-lasting performance against water damage.
Can Waterproof Drywall Paint Make a Difference?
Applying waterproof drywall paint is a popular method to improve the moisture resistance of drywall. This paint prevents mold on drywall and mildew while adding an extra layer of defense against moisture. Waterproof drywall paint, when used with a primer, can make drywall last longer in humid areas. This method doesn’t fully waterproof drywall and is less effective in extremely wet conditions.
Final Thoughts
While waterproof drywall offers better protection against moisture than regular drywall, it cannot fully prevent water damage. Choose waterproof drywall for bathrooms and showers to suit high-moisture areas, ensuring it fits the specific environment properly. Waterproof drywall works well in slightly damp areas. However, for places with direct water exposure, it’s best to use true waterproof materials. Options like PVC panels or cement board are recommended.
When considering the waterproof drywall price, remember that long-term water protection often requires more robust materials and that drywall may not always be the most reliable option. For wet areas, choosing waterproof drywall options can help you avoid regular repairs and replacements later on.
