Can Redgard be used over drywall?

Answer

Even though RedGard can be used on drywall, when all of their product information is taken into consideration, it is not the case that RedGard can be used on Drywall in a damp environment, as they claim. There is no industry standard that I am aware of that supports the use of a liquid membrane on drywall in a wet environment.

Furthermore, is it possible to waterproof drywall?

Yes, it is possible to make drywall almost completely waterproof by coating it with water-based urethane on both sides and edges before installing the drywall. Using a clear water-based urethane over the paper surfaces of the drywall, including the edges, is the trick to making the drywall waterproof. Do this before you finish the drywall and it will be waterproof.

Will RedGard adhere to paint in the same way?

RedGard develops a membrane that is both watertight and crack resistant. It is quite simple to apply RedGard to any surface. If you can paint a wall, you should have no trouble with RedGard.

The question is also raised as to whether RedGard may be used instead of joint compound.

Thinset will not address your issue if you just cover the joint compound with it. Thinset is not waterproof, thus water will seep through and cause problems to develop. To waterproof the cement board and joints, you have two options: remove the joint compound and mud and tape with thinset, or put a waterproofing membrane such as redgard over the cement board and joints

What is the proper name for waterproof drywall?

Drywall may be waterproofed by priming it and painting it once it has dried. Despite the fact that water resistant drywall — sometimes known as greenboard or blueboard due to its colour — is readily accessible at most home improvement shops, you may find yourself in the position of needing to waterproof your existing drywall.

Is it necessary to place drywall behind the tub surround?

Fiberglass and acrylic tub and shower enclosures are designed with a flanged edge that connects directly to the wall studs, and the correct approach to conceal this flange is to cover it with drywall before installing the enclosure. As a result, enclosures are often built on the bare studs of the building.

What kind of drywall is used to cover the wall behind a shower?

Blueboard is a form of drywall that is widely used in showers to create a tiled wall behind the shower curtain rod. Not only is blueboard water-resistant, but it is also readily available and reasonably priced, making it an excellent choice for individuals on a tight budget.

Is it necessary to seal the drywall before painting it?

After you’ve completed hanging the drywall and ensured that all of the seams are taped and finished, you’ll need to apply two coats of paint to the wall to give it its final look. Priming the drywall and mud with primer is required prior to applying those coatings, of course. Using self-priming wall paint may provide acceptable results in certain situations.

Is it OK to use ordinary drywall in a bathroom?

If you want to hang drywall in the bathroom, you may, but not the same sort of drywall that you would use elsewhere in the home. In order to identify it from ordinary drywall, bathroom drywall must be moisture-resistant and green in colour to separate it from the usual version In locations where water will be present, such as shower and tub surrounds, this is not an acceptable material to use.

Is it mandatory by code to have moisture resistant drywall?

Because of changes made to the 2006 International Residential Code (IRC), moisture-resistant, paper-faced drywall (often known as “green board”) is no longer considered a viable tile backing material in wet areas such as tub and shower surrounds.

Is it necessary to use RedGard instead of Hardibacker?

The hardi may be protected with either a vapour barrier behind it or with a waterproofing treatment (such as redgard) over it, but you should not use both methods simultaneously. As Vic previously said, hardi is not watertight, therefore there is no need to be worried about the seams. Water will have no effect on Hardi, despite the fact that it is not waterproof. It will not be harmed by water.

Is Thinset compatible with RedGard?

When it comes to the walls, thinset over Redguard will suffice. When tar paper or poly is not used as a vapour barrier behind the CBU, it is suggested for waterproofing niches, shelves, and complete shower walls, among other applications.

Is it necessary to put RedGard on top of cement board?

As long as it’s Cement Board and not some horrible “nearly” cement board nonsense, I’m ok with whatever. You don’t actually need the RedGard, but the more protection you have, the better, so go ahead and get it. And, certainly, you may prepare the boards ahead of time. However, as soon as a panel is finished, start working on the filled seams and screws (your weak areas) to allow them some time to firm up.

Is it okay to apply RedGard on the shower floor?

Shower pan lining with redgard is not a code-approved way of construction. Pre-slope the mud bed and add CPE liner, then redgarde the mud if you wish.

What much of RedGard do I require?

Using RedGard at a rate of 50 square feet per gallon, apply two coats at a rate of 50 square feet per gallon. Cracks up to 1/8″ (3 mm) in diameter should be prefilled before the waterproofing coating can commence.
