As a homeowner, you may be wondering if an adhesive can sick to Redgard. Fortunately, we have done some research for you, and here is what we found.
This depends on the type of adhesive. Premixed thinset mortar will not stick to Redgard. However, powdered mortar mixed with water has a stronger bond with a surface coated with Redgard.
For a good result, it is better to choose an ideal adhesive for your work. Keep reading to get detailed information on how to work on walls coated with Redgard.
Will Adhesive Stick To Redgard?
For efficient bonding, an adhesive is really needed. Redgard is a waterproofing membrane and can be used for both interior and exterior projects. Whether the adhesive will stick to Redgard or not depends on the type of adhesive and how it is made.
If the adhesive is premixed, it will be difficult to stick to Redgard, and you may end up seeing your tiles pop off the wall. It may not fall off immediately, but it will after a short time.
Using other waterproofing membranes with premixed adhesive won't work either.
Adhesive That Goes Well With Redgard
Now you know that nothing good comes out of using premixed adhesive on Redgard because it will not stick well, you can consider powdered adhesive.
Powdered adhesives are lightweight, thereby aiding easy movement. They can also be used for other purposes. Using a suitable adhesive makes your tile stick well to the surface, thereby offering longevity.
To prepare the powdered adhesive for use, you must pour 5 pounds of the adhesive powder into a bucket and mix it with cool water until it has a peanut butter consistency. Then you can apply it on the surface coated with Redgard.
By doing this, you tend to achieve a better result, as your tiles will not pop off. The only drawback of this adhesive is that it is expensive.
Can I Tile Directly Over Redgard?
Yes, it is okay to tile over Redgard. You can have your tile placed directly over Redgard as long as it is already dried. Once the thinset has been applied to the Redgard, you can place your tile on it.
Also, you can mix the adhesive in batches and apply it to the wall surface bit by bit in order to achieve the best result. Doing this before placing a tile directly ensures long-term durability.
However, you can use a tile trowel to distribute the adhesive when tiling.
Generally, Redgard can be used before the flooring. With Redgard installed, water can't penetrate the subfloor and cause damage. When Redgard dries up, the red color can still be spotted just on the subfloor.
Before the main layer, you should consider using this barrier on your flooring.
Can You Paint Over Redgard?
Redgard is an essential product that makes the remodeling of your project much easier. And yes, you can paint over it. However, remember that the product won't be under warranty.
The warranty shows that the manufacturer is confident that the product will stand the test of time for a specific duration. So when you apply paint over it, the warranty provided becomes void, and there is no assurance that the product will last as it should.
The primary reason why the manufacturer can no longer guarantee the efficiency of the product is because of the chemicals used to produce the paint. The type of paint you use may not work well with the product.
Besides, if the surface is not prepared correctly, it may have a negative impact on the Redgard. However, if you have decided to paint over Redgard, here are the steps to follow:
Step 1: Get The Needed Material Ready
Ensure you get your drop cloth and other supplies ready. The cloth will be used to protect the ground. Painter tape is also required to prevent the paint from spilling over the edges.
Step 2: Apply Primer
This is an essential part of this process. Using a high-quality primer ensures that paint does not fall off the wall and keeps the Redgard in good condition. You can sand the surface so the paint will stick properly to the wall.
Step 3: Add Paint Over The Primer
After applying the primer, at least two coats of paint should be applied over it to protect the surface, as paint can also serve as a sealant. But if you want to use one paint coat, it is best to thin the primer.
However, it is recommended that you use two paints. Also, note that the longer the time given for the paint to dry, the higher its chances of holding up.
After doing these, it is essential to inspect it over the years. This is to ensure that there are no issues with the paint.
When you notice the paint breaking down or falling apart, the best thing to do is repaint rather than try to remove the Redgard. Waterproofing your wall is a good investment for a long-term project.
Can You Remove Redgard?
Yes, you can remove Redgard before painting, but you must follow due process. The process is much easier if the product has been installed for an extended period.
This means that the longer it has been in place, the easier it is to remove because it wears out over time.
However, to get rid of this waterproofing membrane from the surface, a stripper is needed. A stripper is a paint remover that can help to break down the Redgard.
This product can be seen easily because of its color, making the process easier as it will look different and glaring, unlike other waterproofing products.
Instead of removing this product, you can save yourself the stress by applying a new layer to freshen it up and then paint to achieve a good look. If you know how to apply Redgard on your own, removing it won't be difficult.
Can You Use Redgard On Bathroom Floor
Redgard is not that important on a bathroom floor. However, it can be used in the walls and floor of any shower.
Most manufacturers advise using Redgard since it can serve as a decoupling membrane, especially for tile, preventing cracking.
It serves as a waterproof for shower stalls. But, a good substrate will be required, and you must use at least two coats for an ideal thickness.
To install Redgard, you should prepare your wall. After that, you can go ahead to coat every area using a brush.
Make sure to scoop a good quantity and spread it properly. After coating all angles, make sure to cover the entire wall using a paint roller and pan. This step should be done carefully as it determines how the surface will finally look like.
Can You Sand Redgard?
No, you cannot sand Redgard. It is essential to prime before painting over RedGard. When this is done, the paint can merge with the surface coated with Redgard.
You have to apply the primer since you cannot sand. Redgard doesn't sand and usually lasts for years when applied.
Is Redgard Toxic?
Redgard is only toxic when swallowed or if you stay in an enclosed area with it. Breathing in the fumes for a prolonged period of time is not good for your health.
Always wear a mask and make sure there is a free flow of air when working with the substance. Generally, Redgard dries after some hours. For the smell to stop entirely, you have to leave it for days.
If you are uncomfortable with the smell and would like it to stop quickly, give the area good ventilation.
To Wrap Up
If you want your adhesive to stick to Redgard, you should get a powdered type and mix it with water. This has a stronger bond with a surface coated with Redgard compared to premixed thinset mortar.
You can paint over Redgard when the need arises. All you have to do is gather the needed tools, apply your primer and then paint.
