Well, you will be surprised by the benefits this small investment comes with. It is a long term solution that has now become an essential part when constructing wet places such as DIY walk in shower, saunas, and steam rooms.

The problem with water going through the tiny cracks of the wall is that it can weaken the cement board and other substrates. This will eventually damage the shower wall.
2. Prevents Mold
Waterproof isn’t only about protecting the shower from structural damage. It can also stop molds from forming. The buildup of moisture results in the growth of molds and fungus. This can cause health issues, such as allergies.
3. No More Costly Repairs
Without a waterproof membrane, the insides of your shower will start to get damaged and might even shift a little. This will cause the tiles of your shower to crack.
Repairing damages can get a bit costly. With a waterproof membrane, you can easily avoid this problem as the moisture won't be able to go through the membrane.

5. Easy To Apply And Install

Things to Consider Before Buying A Shower Waterproofing Membrane
There are certain factors to consider when purchasing a waterproofing membrane. Getting the one that meets your needs will keep your shower waterproof for a long time.
There are various types of waterproofing membranes available on the market. In this article, we have focused on the two best varieties which are the liquid and fabric membranes.
Liquid membranes are very versatile. That is why they are one of the best waterproofing membrane for showers. They can be applied in a wide range of wet places such as showers, steam rooms, and saunas.

Fabric membranes are also a great choice to make your shower waterproof. Most fabric membranes are applied on a coat of thinset, and then another coat of thinset is applied on the fabric.
They are pliable and are incredibly easy to install. Both the membrane options are great at keeping your shower waterproof.
The membranes have to be easy to apply. Certain products may not stick to the thinset, and peel off after applying. If this happens, the shower may not be fully waterproof.
If you are purchasing a polyethylene membrane, make sure that the material will stick to the thinset properly. Certain fabrics have unique textures to help stick to the thinset.
If you choose a liquid membrane, it has to be easy to apply. Some of the top liquid membrane brands can be applied in multiple ways. The coats should also have a quick dry time so that subsequent coats can be added.
You want a waterproof membrane that will last years. Membranes that cracks or tears will eventually damage the shower. Look for the membranes that are tear-free and strong.
The time it takes for the membranes varies a lot from product to product. The faster the product dries, the better. This allows you to apply more coats at a small amount of time.
Frequently Asked Questions
1. What Is The Drawback Of Using Waterproof Shower Membranes Compared To Other Methods?
Waterproof shower membranes are one of the apt choices when it comes to stopping leaks from showers. But as with other methods, this too has a small drawback.
An issue you might face when installing the membrane is when covering the seams. Waterproofing is achieved by placing the sheets on top of each other. When it comes to the corners or edges, the overlapping of sheets causes them to stick out.
The other common issue most people face is keeping the wrinkles out of the membrane.
These drawbacks are common and can be easily overcome by planning and installing the membrane properly.
2. What Issues May I Face By Not Installing The Waterproofing Membrane For Showers Walls Correctly?
There are a few issues you may face if the waterproofing sheets are incorrectly installed. Cracked tiles are one of them. This might not be caused due to leakage. Water leakage will cause the substrate to expand and contract. This will then cause the tiles to break.
The other problem caused by incorrectly installing the membrane is water stains. Also, the bubbling of the soft wall is a good indication that there is an area that is not covered by the sheet.
3. Can I Install The Membrane Myself?
It's advised to call an experienced plumber and get the job done. If you don't know how to install the sheets, it is possible you might not get it right the first time.
The instruction may seem like an easy task, but if you don't get it right, you may have to remodel the shower again. That might get expensive.
Consulting an experienced remodeler reduces the risk of your shower leaking anytime soon. This gives you the satisfaction of knowing that your shower will be leakage free for years.
4. How Long Will The Membrane Keep The Shower Waterproof?
This depends on several factors. Apart from the quality of the waterproofing membrane material, it also depends on the preparation and application.
A low-quality product has a high risk of not working. Preparing the membrane incorrectly will likely result in leakage as well. The waterproof surface must be cleaned properly and has to be free from dirt and dust particles. If the surface isn't clean, the membrane may eventually come off.
The application will also determine the longevity of the membrane sheets. Every millimeter of the surface has to be covered. This way, the membrane sheets will last for a long time.
5. How Do You Apply A Waterproof Membrane?
When preparing to install a waterproofing for shower membrane, the first step is to make sure that the surface is clean. All surfaces must also be structurally sound, dry, and free from contaminants that would prevent a good bond.
For installations on concrete, newly poured concrete must be troweled smooth and textured to a fine broom finish and then cured for a long time.
To install the membrane, you will need a roller and brush, trowel, and an airless sprayer. Apply the membrane by coating the corners and the intersections where the floors and walls meet.
If you have any gaps or cracks, place a 6-inch wide fiberglass mesh into the wet membrane and then cover it more coats. You will know that the membrane is dry when you see it changing color.
Depending on various factors, this will take about 60 to 90 minutes. When this occurs, you are ready to apply RedGard in the other areas.
If you are applying the membrane using a trowel, apply for one pass by using the notched side. Hold it at a 45-degree angle. Use the flat side of the trowel to flatten the ridges.
If you’re using a roller, coat the surface with overlapping motion. Coat the surface again after the first coat has dried off and changed color.
6. How Many Ways Can The Liquid Membrane Be Applied?
Liquid membranes can be applied in three different ways.
Using a roller and a paintbrush, you can coat the intersection where the floors and walls meet. Use a trowel to level the coatings. When you are using a roller, make sure that you apply even coats.
You can also apply the coating by using a trowel. Spread the liquid waterproof membrane with the notched side of the trowel held at a 45-degree angle. After that use the flat side of the trowel to flatten the ridges.
An airless sprayer can also be used for the application. The sprayer must produce between 1900 to 2300 PSI, and have a flow rate of 1 to 1.5 gallons per minute. Apply the shower membrane in a smooth, continuous spray. Overlap the coverage to ensure the proper thickness is achieved.
7. How Do I Test My Waterproof Membrane For Leaks After Installing?
The only way to know that your shower isn’t leaking after you have installed a waterproofing membrane is by doing a flood test. It is a simple and straightforward test.
To do this, simply pour water on your shower pan. After some time, mark the water level. Then leave the water overnight and get inspect if the water level has dropped or not. If the water level has decreased, then you have a leak in your shower.
8. What Is A Cement Backer Board?
Cement backer board is a material that is placed before the tiles. It is an inexpensive material that eases the building process and makes it look nicer at the end. It also makes the walls more durable. The board is porous, which allows the thinset to easily adhere to the surface.
In the old days, water leakage wasn’t as big of an issue. Older homes had a significant amount of drafts between the exterior and interior. This caused any water leakage to evaporate.
Nowadays, people use their showers a lot more than they used to. The length of time people spend in the showers is going up, as a result, more water gets exposed to the shower walls. The membrane now has to perform at a higher rate on a more regular basis.
Even with all these challenges, installing the best waterproofing membrane for shower will prevent the wall from getting damaged.
We hope you get the solution that fits all your shower needs. Take care!
