How to Build a False Wall for TV and Fireplace: Step-by-Step Guide.


Step 1: Planning And Measuring

Determining The Location For The False Wall

Before you start building the false wall for your tv and fireplace, it is essential to determine its location. Here are some key points to consider:

  • The wall’s location should be far enough away from the actual wall to accommodate the tv and fireplace’s size.
  • Ensure that the location remains central enough to allow for comfortable viewing from any angle.
  • Determine if there are any obstructions in the way, such as pipes or electrical wires, which might need to be rerouted or accommodated in the design.

Measuring The Area To Be Covered

Once you have decided on the wall’s location, it’s time to measure the area to be covered. Here are some critical points to keep in mind:

  • Firstly, make sure that you measure the height and width of the wall correctly.
  • Ensure that you mark any obstructions in the wall, such as windows or doors, and make allowances for them in your measurements.
  • It is crucial to measure the depth of the wall by taking into account the size of the tv and fireplace that you are planning to install. This will ensure that you create enough space for both items.

Remember, accurate measurements are key to building a successful false wall that fits your tv and fireplace snugly. Taking a little extra time to measure accurately can make your building process more efficient in the long run.

Step 2: Building The Frame

Now that you have gathered all the necessary tools and materials, it’s time to start with building the frame for the false wall. This step is crucial as the frame will hold the entire structure together. Here are the key points to keep in mind:

Cutting The Lumber To Size

  • Cut the top and bottom plates according to the length of the wall that you want to build. The plates should be 2×4 lumber and should run parallel to each other.
  • Cut the studs to the desired length. The studs should be 2×4 lumber as well and should be placed vertically between the top and bottom plates.
  • Make sure to measure everything accurately to ensure a precise fit.

Assembling The Frame

  • Begin by placing the bottom plate on the floor in the desired location. Use a level to ensure that it’s straight.
  • Attach the studs to the bottom plate by nailing them in place. Make sure they’re evenly spaced.
  • Once all the vertical studs are in place, add the top plate and nail it to the studs. Use a level to ensure that it’s straight.
  • Finally, add a diagonal brace between the top plate and each stud. This will add extra stability to the frame.

Attaching The Frame To The Wall And Floor

  • Move the frame into place against the wall. Make sure it’s level before securing it to the wall studs using bolts.
  • To secure the bottom plate, use construction adhesive and nail it to the floor joists.
  • Make sure that the frame is securely attached to both the wall and floor, as this will provide the needed support for the weight of the tv and fireplace.

Building the frame is a crucial step in creating a false wall for your tv and fireplace. By following the steps outlined above, you can ensure that your frame is sturdy and securely attached to the wall and floor. With this base in place, you can move on to the next steps in creating your beautiful and functional false wall.

Step 3: Adding The Drywall

If you’ve followed the previous steps in building a false wall for your tv and fireplace, you should now be ready to add the drywall. This step involves cutting the drywall, securing it to the frame, and taping and sanding the seams.

Here’s a step-by-step guide on how to do it right.

Cutting The Drywall To Size

Before cutting the drywall, measure the height and width of the wall frame to determine the size you need. Mark the drywall with a utility knife and use a drywall square to align it for accurate cutting.

Next, score the back of the marked line with the utility knife, applying moderate pressure. Bend the drywall along the scored line until it snaps, then use the utility knife to cut the remaining layer of paper on the front side of the drywall.

Securing The Drywall To The Frame

Once you have cut the drywall to size, it’s time to secure it to the frame. Begin at the top of the frame and work your way down, using drywall screws every 12 inches along the studs and the perimeter of the drywall.

Be sure not to overdrive the screws as they can break the paper of the drywall. Use a drill bit that corresponds to the size of the screw to make pilot holes in the drywall and ensure a smooth installation.

Taping And Sanding The Drywall Seams

After securing the drywall to the frame, it’s essential to tape and sand the seams for a smooth, seamless finish. First, apply joint compound along each seam, making sure to press it firmly into the joints.

Next, carefully lay drywall tape on top of the joint compound and smooth out any air bubbles or creases. Using a wide joint knife, cover the tape with another layer of joint compound, feathering the edges as you go.

Finally, once the joint compound has dried completely, sand the seams until they are smooth and even. Use a sanding pole and fine-grit sandpaper, working in a circular motion to blend the seams seamlessly with the drywall.

Building a false wall is a multi-step process that can be challenging but rewarding at the same time. Hopefully, this step-by-step guide has provided you with the knowledge and confidence to tackle this diy project with ease.

Step 4: Installing The Tv And Fireplace

Mounting The Tv To The False Wall

Once the false wall framing is complete, it’s time to mount the tv using the appropriate hardware, which usually consists of a mounting bracket and lag screws. Here are some key points to remember:

  • Locate the studs within the false wall and position the mounting bracket accordingly to ensure it’s anchored securely.
  • Use a level to make sure the tv is straight.
  • Double-check the bracket’s weight capacity to avoid damaging your tv’s screen.

Running Cables And Wires Through The Wall

With the tv mounted, it’s time to hide those unsightly cables and wires. Here’s what you need to do:

  • Determine the appropriate location to drill holes in the false wall, keeping in mind the location of the tv and any other components you plan to connect.
  • Drill holes in those locations and use a fish tape or wire snake to run the cables and wires through the wall.
  • Use velcro or cable ties to secure the cables and prevent tangling.

Installing The Fireplace And Venting System

Before installing the fireplace, consult the manufacturer’s instructions to ensure safe and correct installation. here are some key points to remember:

  • Determine the proper clearance for your fireplace and its venting requirements, which can vary depending on the type of fireplace and fuel you’re using.
  • Install the vent pipe into the chimney or exterior wall, following the manufacturer’s instructions.
  • Secure the fireplace to the false wall framing using brackets or other recommended hardware.
  • Test the fireplace and make sure it’s functioning properly before closing up the wall.

By following these steps, you can create a beautiful and functional false wall with a tv and fireplace. The result will be a space-saving addition to your home that’s both stylish and practical.

Step 5: Finishing Touches

Painting Or Wallpapering The False Wall

  • Paint color: Choose a color that coordinates with the existing room decor. Use a high-quality paint that is suitable for painting walls, with a satin or eggshell finish for easy cleaning and durability.
  • Paint application: Use a roller brush for larger areas and a paintbrush for corners and edges. Apply two coats of paint for a smooth and even finish.
  • Wallpaper installation: Measure the area of the false wall and cut the wallpaper to the correct size. Using wallpaper paste, attach the wallpaper to the false wall in a vertical pattern. Make sure to smooth out any air bubbles or wrinkles.
  • Wallpaper design: Choose a wallpaper design that matches the decor of the room. Consider using a wallpaper with a textured or 3d effect to add depth and interest to the false wall.

Adding Shelving Or Other Decorative Touches

To make the false wall a functional and decorative feature in your room, consider adding shelving or other decorative touches. Here are some key points to remember:

  • Shelving design: Choose a shelving design that complements the style of the room. Use floating shelves for a minimalist look, or glass shelves for a more contemporary feel.
  • Shelf installation: Use a level and stud finder to ensure that the shelves are evenly installed and secure. You can also use brackets or supports for added stability.
  • Decorative touches: Consider adding artwork, picture frames, or other decorative elements to the false wall. Use a cohesive color scheme or theme to tie everything together.

Concealing Any Visible Wires Or Cables

To ensure that your false wall looks seamless and polished, it’s important to conceal any visible wires or cables. Here are some key points to consider:

  • Cable management: Use cable management tools such as zip ties, cable sleeves, or cord covers to bundle and conceal wires and cables.
  • Power outlets: Install power outlets within the false wall for a cleaner look and easier access to outlets.
