What Are The Benefits Of Using Redgard Over Cement Board?
Redgard is a waterproofing and crack-resistant membrane used in showers and other wet areas, while cement board is commonly used as a base for tile in dry areas.
If you are waterproofing a shower or bathroom, you have probably heard of Redgard. This product is a waterproofing and crack-prevention membrane that is applied over cement board or directly to concrete, masonry or brick before tile is installed. Redgard has many benefits over cement board, making it the better choice for waterproofing your shower or bathroom.
Redgard is a ready-to-use elastomeric membrane that cures to a tough, durable finish. It is flexible, so it will not crack if the substrate moves. Redgard also bonds well to most surfaces, so it can be applied directly to concrete, masonry or brick. It can also be applied over cement board.
Redgard is also easy to apply. It can be rolled or sprayed on and does not require a primer. It dries quickly, so you can tile over it in as little as four hours.
Redgard is also cheaper than cement board. A gallon of Redgard covers about 50 square feet, compared to 30 square feet for a sheet of cement board.
Redgard also has better waterproofing properties than cement board. It is a seamless membrane that creates a watertight bond to the substrate. Cement board is porous and can allow water to seep through.
Redgard is the better choice for waterproofing your shower or bathroom. It is easy to apply, bonds well to most surfaces, dries quickly and is more waterproof than cement board.
How Does Redgard Over Cement Board Compare To Other Waterproofing Methods?
It is a more effective waterproofing method.
If you’re waterproofing a shower, you have a few different options. You can use a pre-fabricated shower pan with a liner, you can waterproof the shower area with a waterproofing membrane like Schluter Kerdi or RedGard, or you can waterproof the shower with cement board and thinset mortar.
So, how does RedGard over cement board compare to other waterproofing methods?
Here are a few things to consider:
1. Cost: Pre-fabricated shower pans can be expensive, and Schluter Kerdi or RedGard can add up if you’re doing a large shower. Cement board is relatively inexpensive and easy to install.
2. Ease of installation: Pre-fabricated shower pans are the easiest to install, followed by Schluter Kerdi or RedGard. Cement board takes a little more time and effort to install, but it’s not difficult.
3. Waterproofing: All three methods will waterproof your shower, but Schluter Kerdi and RedGard are probably the best at it. Cement board does a good job, but you may want to add an extra layer of protection with a waterproofing membrane.
4. Durability: All three methods are durable, but cement board is the most durable. It’s not uncommon for pre-fabricated shower pans to crack or leak, and Schluter Kerdi and RedGard can eventually degrade and fail. Cement board will last as long as your house does.
5. Aesthetics: This is a personal preference, but some people prefer the look of cement board over the other options.
So, there are a few things to consider when deciding which waterproofing method to use for your shower. If cost is a concern, cement board is the way to go. If you want the easiest installation, go with a pre-fabricated shower pan. If you’re looking for the best waterproofing, Schluter Kerdi or RedGard are your best bet. And if you want something that will last a lifetime, cement board is your best option.
How Long Does Redgard Over Cement Board Last?
It depends on the thickness of the Redgard and how it is applied.
Cement board is a common substrate used for tile projects, especially in wet areas like showers. It’s made of Portland cement, aggregate, and glass mesh, and it’s very dense and waterproof.
Redgard is a waterproofing and crack-prevention membrane that’s often used on top of cement board before tile is installed. It’s made of elastomeric rubber and fiberglass, and it’s applied with a roller or brush.
So, how long does Redgard over cement board last? It depends.
If the Redgard is applied properly and the cement board is in good condition, the Redgard should last indefinitely. However, if the Redgard is applied too thinly or the cement board is damaged, the Redgard may only last a few years.
To get the most out of your Redgard, make sure to follow the manufacturer’s instructions and inspect the cement board for damage before applying the Redgard.
How Often Do You Need To Reapply Redgard Over Cement Board?
Redgard should be applied over cement board when creating a waterproofing and vapor barrier for shower stalls, tub surrounds and balconies.
If you’re tiling over cement board in a wet area like a shower, you need to apply a waterproofing material like RedGard over the cement board. RedGard should be applied according to the manufacturer’s instructions, which usually means applying it with a roller or brush in a thin, even layer and letting it dry for at least 24 hours before tiling.
