The Perfect Mud For Plastic Shower Walls

how to mud a plastic shower wall

Plastic shower walls can be removed and replaced with more stylish or modern options. Removing glued shower wall panels is easier than removing direct-to-stud panels, which require extra tools and time. To remove glued panels, use a hair dryer to soften the adhesive, then carefully cut away any caulking around the edges of the panels with a putty knife or razor blade. Afterwards, use a putty knife or pry bar to carefully pull the panels away from the wall, being careful not to damage any surrounding tiles or wood finishes. Finally, use a vacuum cleaner to remove any dust particles. When installing new shower walls, it is important to measure the square footage of the walls and purchase the corresponding amount of material. After installing the shower walls, mud and tape the screw holes and joints to secure them. Finally, apply a waterproofing product to ensure that the walls are watertight.

Removing glued plastic shower wall panels

Prepare the Workspace:

Before beginning the removal process, ensure you have the necessary tools, including a putty knife, razor blade, drill with a hole saw attachment, utility knife, lubricant (such as WD-40), alcohol, and a vacuum cleaner with an extraction hose attachment. It is also recommended to wear protective gear, such as gloves and goggles, to safeguard against any debris or chemicals.

Remove Fixtures:

If the plastic shower wall panels surround any bathroom fixtures, it is important to remove those fixtures first. This may include items such as the showerhead, tub spout, shower arm, and faucet trim. Be sure to turn off the water supply before removing any plumbing components.

Cut Around the Panels:

Use a utility knife to cut through the sealant or caulking that seals the panels to the shower base or adjacent panels. Cut along the edges of the panels and any areas where panels overlap. This step will help you separate the panels from the surrounding structures.

Remove Molding and Corner Panels:

Use a putty knife to tap behind any molding or trim around the outer edges of the panels. Pry gently to remove the molding. Then, focus on the corner panels. Insert the putty knife behind a corner panel and tap it deeper until the panel starts to come away from the wall. Continue tapping and pulling until the corner panel is removed. Repeat this process for all corner panels.

Remove End and Back Panels:

Beginning at the top outside corner, use the putty knife to pry an end panel away from the wall. Once you can grip the panel, carefully pull it off. Repeat this process for all end panels. Back panels can be removed using the same method. After removing the panels, clean up any glue residue and fix any tears or damage to prepare the wall for new panelling.

Unfasten Panels from Studs:

Panels are typically attached to studs using screws or nails. Use a drill with a screw bit to remove screws, and a cat's paw pry bar to remove nails. Back out the screws or pry out the nails to unfasten the panels from the studs.

Final Clean-up:

Once all the panels have been removed, use a vacuum cleaner with low suction power to remove any dust or debris created during the removal process. Additionally, use alcohol to wipe away any remaining adhesive residue. For stubborn residues, apply an alcohol-soaked rag to the area for several minutes to soften the adhesive before rubbing it away.

Removing direct-to-stud plastic shower wall panels

To remove direct-to-stud panels, you must expose the nailing flange, which is done by removing part of the wall. For tiled walls, this means removing at least one row of tiles along the top and side edges of the surround. The panels usually need to be removed in the reverse order of their installation, starting with the corners, moving to the side panels, and ending with the back panel. The corner and side panels may be connected by a latch system, so unlatch them by lifting the panel you are removing straight up.

To remove the panels, you can use a putty knife or a pry bar to carefully pull them away from the wall. Ensure that you do not scratch or dent any nearby surfaces, such as tiles or wood finishes. You can also use a drill with a hole saw attachment to create small holes around the edges of each panel. This allows you to insert a utility knife to cut away pieces of the panel. Make sure to lubricate each hole to prevent the knife from getting stuck. Finally, remove any remaining adhesive residue with alcohol.

It is important to note that heating the front of glued panels with a hair dryer can help soften the adhesive, but it may create a gooey mess. Therefore, it is recommended to attempt removal without heat first and only use the hair dryer if necessary. Additionally, you can use a vacuum cleaner with an extraction hose attachment on low suction power to remove any dust particles created during the removal process.

Waterproofing the shower wall

Prepare the Surface:

Before you begin waterproofing, ensure that your shower wall is properly prepared. This includes measuring the square footage of the wall to purchase the correct amount of materials. Additionally, measure and cut out spaces for any shower valves, knobs, and pipes. It is important to plan ahead to ensure a precise fit for your shower fixtures.

Select Waterproof Materials:

Choose materials specifically designed for waterproofing. Avoid using regular drywall or sheetrock, as these break down in the presence of moisture. Instead, opt for waterproof foam boards, cement boards, or specialised products like DensShield or DuraRock. These materials are designed to withstand moisture and provide a durable base for your shower wall.

Apply Mud and Tape:

Use a heavy-duty mesh tape specifically designed for damp environments, such as FibaTape or Kerdi band. Mud over the screw holes and joints to secure the tape and create a smooth surface. This process may involve multiple layers of mud and tape to ensure a watertight seal.

Seal the Gaps:

Pay close attention to gaps and seams between boards. Apply a generous amount of adhesive and sealant to these areas to create a waterproof barrier. For example, you can use Laticrete Hydroban adhesive and sealant or a similar product. This step is crucial in ensuring that water does not seep through the cracks and cause damage.

Waterproof Membrane:

Consider using a paint-on waterproofing membrane or a pre-installed waterproofing membrane, such as the one found on Kerdi boards. This extra layer of protection ensures that your shower wall is fully sealed and protected from water damage.

Final Touches:

Once the mud is dry, apply a waterproofing goop or sludge to cover any potential holes and cracks. This step guarantees that your shower wall is entirely waterproof. Be sure to follow the manufacturer's instructions for any products you use and always conduct a final inspection to ensure that your shower wall is securely sealed and ready for tiling.

Remember, waterproofing your shower wall is a high-stakes job, but with careful planning, the right materials, and a systematic approach, you can successfully create a waterproof shower that will last for years to come.

Using mesh tape to secure joints

When mudding and taping a plastic shower wall, using mesh tape is a crucial step to secure the joints and ensure a watertight seal. Here's a detailed guide on using mesh tape for this process:

Selecting the Right Mesh Tape

Before you begin, it's important to select the appropriate mesh tape for your project. Look for alkalai-resistant mesh tape, which is specifically designed for use in shower areas. This type of mesh tape can be found at most hardware stores or home improvement centres, usually near the cement board section. Mesh tape is a better option than paper tape in damp environments like bathrooms because it resists mould and provides a stronger, longer-lasting seal.

Preparing the Surface

Before applying the mesh tape, ensure that your shower walls are properly measured, cut to size, and screwed into place. Measure and cut out smaller pieces, as well as irregular pieces, to fit around shower valves and knobs. You can use a utility knife to score and snap the pieces to the correct size. Screw the DensShield sheets into the studs of your shower wall frame. Mud over all the screw holes and any joints with a layer of mudding compound. This will create a smooth base for the mesh tape to adhere to.

Applying the Mesh Tape

Once the mudding compound is in place, it's time to apply the mesh tape. Start by pressing the mesh tape firmly into the wet mud over each joint. Use your fingers to smooth out any air bubbles or wrinkles and ensure good contact. You can also use a putty knife or a similar tool to gently press the mesh tape into the mud, ensuring a secure bond. Pay particular attention to corners and ensure that the mesh tape is folded neatly to fit snugly.

Finishing Touches

After the mesh tape has been applied, you can continue building up the layers. Apply a second and third coat of mud over the mesh tape, allowing each coat to dry completely before adding the next. Once the final coat is dry, you can sand the walls with 120-grit sandpaper or a drywall pole sander to create a smooth, even surface. This process will help conceal any indentations or imperfections, resulting in a seamless finish. Finally, apply a waterproofing compound or "goop" over the mudded and taped joints to ensure a watertight seal.

Remember, while these steps provide a general guide, there are many online tutorials and resources that offer more detailed instructions and tips for mudding a plastic shower wall and securing joints with mesh tape. Don't hesitate to seek out additional information to ensure a successful project.

Filling gaps between the shower and drywall

Step 1: Prepare the Surface

Before you begin filling the gaps, ensure that the area is clean and dry. If there is any old caulk or debris in the gap, remove it using a putty knife or a similar tool. It is important to have a smooth and clear surface to work with.

Step 2: Choose the Right Materials

There are several methods and materials you can use to fill the gap between your shower and drywall. You can use a setting compound, such as Durabond, which can be applied in one coat to effectively fill the void. Alternatively, you can use a combination of mud or plaster and caulk. It is recommended to avoid using paper tape, as it can be a source of food for mould in damp environments. Instead, opt for mesh tape, which is more suitable for areas with high moisture levels.

Step 3: Cut and Fill the Gap

If you are using drywall to fill the gap, cut the sheetrock so that it runs up to the edge of the enclosure's mounting flange. You can then pre-fill the recess with hot mud or a setting compound. Make sure to leave a small gap between panels to allow for the expansion and contraction of materials due to temperature and moisture changes.

Step 4: Tape and Finish

Once the mud or compound is dry, you can tape over the gap. Use mesh tape specifically designed for this purpose and apply it to secure the seam over each joint. Finally, finish the area with a standard drywall compound to cover the joint and create a smooth surface.

Step 5: Waterproofing

After the taping and mudding process is complete, it is crucial to waterproof the area. Apply a waterproofing product, sometimes referred to as "goop," over the mudded areas to ensure that your shower is watertight. This step is essential to prevent water damage and mould growth.

Frequently asked questions
