Regard is a prevalent waterproofing material used to establish a ceaseless waterproof membrane barrier on stone and tile floors.
Due to its outstanding convenience, most homeowners find the need to have their walls sealed with this waterproof membrane.
Despite its outstanding convenience, you will not want to leave it as the final coat. That said, there are many ways of top coating regard.
But can you paint over redgard?
Yes, you can paint over redgard.
All you need to do is to apply thinset over the RedGard and follow it with primer application before you paint.
Note that the integrity of the primer you use will dictate whether or not the paint will stick to regard.
It’s interesting to know that painting over regard means you run the risk of losing your warranty. So do it if you are in for that.
Let’s now delve into further details regarding regard.
How Long Can Redgard be Exposed?
Regard is certified to minimize cracks and offer a waterproofing layer for interior and exterior stone and tile installation.
However, if it’s not handled with the care it deserves, it might become punctured or soiled with time.
Therefore, you must protect it from over-exposure to rain, direct sunlight, and rigorous weather for 72 hours after applying it.
Suppose you let it exceed 72 hours; I suggest you cover it using felt paper. This way, you will have protected it from future constraints.
Will Redgard Adhere to Latex Paint?
Redgard should be covered with tile or stone within 72 hours of its installation.
You must by no chance leave redgard unprotected. Also, latex paint is not a suitable protection for redgard.
As much as latex paint is not suitable for protection for redgard, Installing redgard to any surface is by no means a difficult task.
Ideally, regard will easily hold up to latex paint, assuming you choose a suitable primer.
Will Thinset Stick to Redgard?
Yes, powdered, unmodified thinset will adhere to the RedGard waterproofing membrane and safely fuse your tile in place.
The following rules are crucial to ensuring your tile installation goes well and remains durable over time.
- Let RedGard fully dry before you start tiling
- Avoid using premixed thinset mortar as it won’t stick to RedGard
- When using a powdered thinset mortar, ensure you mix it yourself
- Mix the powdered mortar with cool water until you achieve peanut butter consistency.
- Do the tiling in small sections to ensure your mortar is always fresh.
You can use thinset to substitute tar paper or poly to block out vapor on shelves, shower walls, etc.
Suppose you install regard by strictly conforming to the instructions provided; you will not encounter any issues.
So thinset will readily adhere to regard provided you adhere to the necessary procedures.
What Kind of Thinset Should I Use Over Redgard?
Usually, a good quality modified thinset will work well with redgard because it doesn’t require uncoupling.
On the other hand, an unmodified thinset is a better pick for diltra surfaces.
So suppose you mistakenly use unmodified thinset over regard; you will encounter failure shortly.
Can I Install Tile Over Redgard?
Can You Tile Directly Onto RedGard? There’s no point in putting another layer of product on RedGard before you start tiling.
Any surface painted with RedGard and allowed to dry should be ready for the application of thinset and installation of tile.
Feel free to install thinset mortar and tile directly over RedGard.
Once you have finished installing your redgard, you must wait for nearly 24 hours before installing tiles.
You can either install the tile directly onto your walls using a thin-set mortar or use an alternative means.
What Will Redgard Stick to?
The components used to make redgard allow it to bond with clean metal drains, stainless steel, PVC, etc.
Also, you can use it as a slab-on-grade moisture vapor impediment on all sorts of floor coatings.
Will Redgard Stick to Primer?
The essence of primer on any surface is to promote better paint adhesion. Still, it offers extra protection for the painted surface, and redgard is no exception.
So for the paint to adhere to the redgard surface, priming is very important.
However, not all types of primer will do great on redgard surfaces. So be cautious when deciding on the type of primer for your project.
Tip: If the primer fails to blend with the regard, you may want to apply thinset over the redgard. And after that, you can now prime over it.
Can You Use Redgard On Basement Walls?
Almost all of today’s waterproofing products can be employed to coat basement walls.
However, among the many sale options that have flooded the market, redgard remains a stand-out.
Aside from that, it boasts great waterproofing qualities once dry and adheres to any surface enduringly.
Can I Use Redgard on Drywall?
Despite redgard serving as a perfect solution for water leaks and cracks, people still ask how to use it.
The good thing with it is that water won’t damage your drywall if you apply it correctly.
Also, I suggest using redgard on drywall since it offers protection against mold growth, mildew, and rot.
The only issue you will encounter is constraints when installing it. So to avoid such, you need to call a professional to help you in the process.
How Long Does Thinset Need to Dry Before Redgard?
The duration the thinset takes to dry is based on the room’s humidity, airflow, and temperature. Usually, specialists suggest 24 hours.
On the other hand, the surface is ready to walk on after 48 hours.
Can You Put Redgard Over Silicone?
Whereas redgard is perceived to be a multipurpose product, it does not mean it will adhere to everything.
Many homeowners tend to use silicone caulking to seal their demanding tasks, such as building tubs.
But silicone won’t give you the waterproofing barrier you need to deter future damage and cracks.
So, installing redgard over your project’s edges is far better than establishing a solid waterproof barrier.
Remember you are starting with installing the redgard before you can bring in silicone.
After all the parts are dry, it’s ripe time to add your silicone caulking to cover up everything.
Suppose the silicone is already in place; you must peel it off to seal the surface properly.
Even though it’s quite a daunting task, you need to get it right for your project to be completely waterproof.
Are There Limitations to Redgard?
Regard is a good waterproofing product, but it has a few exceptions with it. Check out the list below:
- You should not use redgard as an adhesive.
- When using redgard on any surface, remember to cover it with permanent flooring or tiles. You should never use it as a worn surface.
- As with most waterproofing products, you should never use redgard with solvents.
- Redgard won’t work as expected on wet surfaces and should never be exposed to hydrostatic pressure.
- You should not use this product on surfaces that endure temp below 40 degrees F within 72 hours after applying it.
- Ensure you don’t use this product on existing concrete slabs surpassing 85% humidity levels. You can reach out to your manufacturer for more details regarding the conditions of use.
- This product is not designed for relocating file joints or oversaw cuts in concrete slabs. Alternatively, it’s better to go for Crack Buster Pro Membrane.
How Long Does it Take for Redgard to Dry?
Redgard is considered dry when it transitions to solid red without any pink color. Ideally, the drying time of this product is estimated at 1 to 1.5 hours.
However, this period can extend to 12 hours, depending on the environment setting.
Once the first and second coats fully cure, you can flood test the application area.
How to Apply Redgard
Redgard waterproofing and crack prevention formulas are ideal for floors, walls, and tile assemblies.
Applying it is relatively easy and boasts a quick drying time, unlike its correlatives.
What’s even better, it comes ready to use, thus eliminating the need for strenuous preparation before application.
You can apply it on surfaces using a roller, brush, trowel, or an airless sprayer. For further information, keep reading the simple guidelines below.
Step 1
Before you install redgard, be sure the surface you intend to install is relatively clean and dry.
Applying this product to untidy surfaces can restrict it from holding up well to the surface. You need to use supplies like a mop to clear all the dirt if it’s on the floor.
Step 2
Similar to most DIY projects, your safety is the center of concern. For this reason, it’s wise to put on impermeable gloves, glasses, and dust masks.
Possessing the supplies mentioned above at hand will guarantee your health.
Step 3
Once you are fully prepared, take your tin of regard and shake it well before applying it on your surface.
After shaking the tin for 20 seconds, take your ¾” nap rough textured synthetic roller and begin to apply the redgard.
You might also want to use a paintbrush if it suits you or a 3/16″ by ¼” V-notch trowel.
To begin, you must precoat the niches and the intersections where walls and floors convene.
After that, spread the regard at least 6 inches on both sides of the intersection.
Next, pull back and watch out for any gaps with dimensions exceeding ⅛ inch. If you notice any, reinforce it with a 6″ wide fiberglass mesh tape.
The essence of this mesh tape is to aid in patching holes on the surface, and it works as a paper tape substitute.
You will want to keep the mesh positioned in the corner, then press it firmly on the surface. After that, allow the precoated area to dry.
You will easily know when regard dries when it changes from pink to red. Ideally, it takes between 1 to 2 hours for it to dry.
However, it can last much longer based on the job site condition, humidity, and temperature.
Tip: Ensure you wear gloves to prevent your fingers from abrasion.
Step 4
After the dry time is due, you can add an extra coat. This time you will want to repeat the same thing when applying but put in a generous layer of regard.
Then spread the redgard on the surface using your preferred mode of application: brush, roller, or trowel.
Tip
Suppose you’re using a roller; you must apply a perpetual uniform coat with overlapping strokes.
If using the trowel, apply the redgard using the notched side. And be sure you hold the trowel at a 45-degree angle. Then level the ridges.
When your second coat is dry, examine the dry membrane and fill any spaces of pinholes.
These simple steps will deter minor cracks from spreading through your tiles and concrete floor.

That means you must wait for it to dry before spraying over it fully.
How Do You Spray Redgard on Drains?
As mentioned earlier, redgard is both a waterproofing and crack prevention liquid. After applying, it dries to form a flexible membrane.
Redgard will adhere well to interior and exterior surfaces, including concrete, decks, and gypsum-based materials.
In addition, it also serves as a vapor barrier beneath floor coverings.
To spray regard on drains, check the instructions below.
Step 1
First, apply your redgard on the drain flange and the metallic collar that encircles the seals.
Step 2
Next, install a 12 by 12-inch fiberglass mesh into the fresh redgard. Then clamp the drain flange to the surface and tighten it.
After that, let the redgard heal for merely 1 to 1.5 hours.
Step 3
Next, take silicone caulk and apply it all around the flange. Remember, you should focus on the intersection where the flange meets the membrane.
With these simple guidelines, you will have installed regard to your drain area successfully.
Tip:
If you are applying this product using an airless sprayer, use 1900 to 2300 pounds per square inch. Mind you, the flow rate should be 1.0 to 1.5 gallons per minute for larger areas.
Can You Remove Redgard From a Bathtub?
You can agree that getting rid of redgard after it has dried is very difficult. Luckily, there is a remedy to this issue.
From experience, I suggest that using any solvent is far more recommendable to safely melt down the redgard from its position.
Such solvents may include paint strippers or even paint removers.
Is Redgard Required in the Shower?
Since water occasionally splashes and hits the shower walls, you need redgard to stop the water from paving through the walls.
Most people rely on cement boards and tiles, which don’t seem enough.
On the contrary, there are thousands of showers constructed without waterproofing materials.
So it’s upon you to agree on whether the redgard is a requisite product in your shower.
Will Redgard Stick to the Cement Board?
Redgard is a flexible material that can be applied on most surfaces to prevent future leaks and cracks.
Most homeowners are eager to know whether it excels well on cement board panels.
The truth is that it will stick to all cement board panels, especially if you use a ¾” nap roller.
A ¾” nap roller is a better pick on cement boards as it doesn’t shed too much lint on the redgard.
For the best outcomes, it’s much better to kick off with vertical strokes in the first coat.
Then for the restricted areas, I recommend using a paintbrush. In the process, you will want to focus on all the intersections adjacent to the tub because it’s where water penetrates mostly.
Does Redgard Smell Bad?
Considering that redgard is a solvent-based product, there is no denying that it emits an odor smell. The smell it elicits may react differently to various people.
And it even gets worse in individuals with pre-existing conditions such as asthma and high blood pressure.
The smell will persist on the first few days of application, but it will get less noticeable with time.
However, if the odor continues for long, it’s wise to cover the surface with a vapor barrier such as plastic. And after that, tape it temporarily.
Alternatively, you can seal the regard with a strong sealer, and the odor will disappear over time.
Do You Need Redgard on Hardibacker?
Hardibacker is a tile underlayment sanctioned for use on floors, countertops, and walls. It also functions as a backer board for a myriad of surfaces.

Does Redgard Stick to Joint Compound?
Redgard will stick to any joint compound if you follow the steps put in place. However, various aspects can prevent it from holding up well on joint compounds.
Such aspects include a dusty joint compound with a powdery surface.
When you fail to cleanse your joint compound before setting up regard, there will be zero adhesion.
So it’s wise to prepare the surface thoroughly and apply the proper primer. And later finish off by installing the redgard.
If you don’t notice any difference, reach out to your manufacturer to help you solve the problem.
Tip: Ensure the top layer is free from dust.
Can You Skim Over Redgard?
This is a common question that pinches most homeowners.
Despite redgard being a perfect waterproofer, it needs a skim coating element that offers a masterly finish to surfaces before installation.

How Long Should Mud Bed Cure Before Redgard?
The mud bed should stay for nearly 24 hours before the redgard is installed. Suppose you apply redgard on it prematurely; the topcoat will eventually peel off with time.
Why Does Redgard Crack?
Since redgard is a versatile material, it doesn’t mean you use it uncontrollably. You must follow the steps and rules for this product to work as you expect.
Redgard often breaks down due to insufficient dry time. The label on the bottle indicates the drying duration between each coat.
So if you fail to let the redgard cure fully, it’s likely to form minor cracks on the surface with time.
Another factor that fosters regard to crack prematurely is putting in thick coats. It’s wise to use thinner coats because they dry shortly, unlike thicker coats.
Putting in thicker coats will make the top layer begin to dry while the layer beneath is fumbling to release moisture. As such, the top layer leaves cracks.
Does Redgard Peel Off?
Redgard is made from certified elements and guarantees maximum durability once applied.
This product dries to form a strong membrane and won’t wear out independently unless you pull it from the surface.
For this reason, don’t expect it to peel off from the surface prematurely.
