Yes. RedGard is a popular product that is used to protect surfaces from water and stains. It is often used on floors and walls. However, it can also be used on concrete as well as the HardieBacker board. 

Why Would You Want To Apply RedGard On HardieBacker?

First, let’s talk about green board. It has been in existence for quite a while and was traditionally installed with tiles directly to it. 

Depending on how well they were installed, they’d last upwards of 3-20 years. They can just be replaced when they start to fade and break down due to age or moisture.

On the other hand, HardieBacker is durable and lasts much longer than the traditional green board. In addition, this type of backer board can be installed quickly and easily, making it an attractive choice for new construction projects.

If you are worried about the future of your tile installation, then you should consider applying RedGard to it. 

The membrane will make sure that your tile lasts longer and doesn’t suffer from any damage. The RedGard isn’t crucial, but it is better if you have more protection.

Is It Possible To RedGard Cement Board?

With RedGard, you can create a waterproof and crack-resistant membrane. If you can paint a wall, you can use RedGard. RedGard can be applied to cement board panels in two ways: Roll it on the wall with a 3/4-inch nap roller or spray it on the wall.

Waterproof showers are the trend today, so RedGard is an excellent alternative to cement boards that act as vapor barriers. Visit the Schluter site to find out more about the Kerdi shower from Schluter. It requires no cement board and can be used over drywall.

What Is The Best Way To Remove RedGard?

You can lift RedGard from areas like that if you can get under an edge, as it generally peels off easily. However, thick RedGard may prove more challenging.

Do HardieBacker Boards Have Waterproof Properties?

You can use it on walls, floors, and countertops because it is long-lasting and waterproof.

Can Thin Set Be Applied To RedGard?

The RedGard waterproofing membrane does not adhere well to premixed thin set mortar. A powdered mortar will help your tile adhere well to a waterproofed surface that has been treated with RedGard. 

This mortar has to be mixed with water, but it will ensure that the tile is firmly attached to the wall. And that is all there is to it.

Application Guidelines

When considering the application of RedGard liquid membrane on HardieBacker boards, particularly for areas like a tub surround, it’s crucial to address two questions regarding moisture resistance and durability.

Start by applying a first coat of RedGard to ensure all the seams, screw heads, and corners are covered, creating an effective vapor barrier. Allow the first coat to dry thoroughly before applying the second coat, ensuring you achieve the recommended thickness.

For an average-sized tub surround, approximately one gallon of RedGard is required to apply two coats, providing a robust moisture-resistant barrier that allows you to tile directly onto the surface. Remember, this process was established years ago and has proven effective in protecting against moisture when using liquid membranes like RedGard.
