How to Get Rid of Seams in Mobile Home Walls

Quck answer

Mobile home walls often have visible seams due to the construction process. These seams can be unsightly and make the walls look unfinished. To eliminate seams in mobile home walls, follow these steps:

1. Prepare the walls: Clean the walls thoroughly to remove any dirt or debris. This will ensure a smooth surface for the repairs.

2. Fill the seams: Use a joint compound or spackle to fill in the seams. Apply the compound evenly and smoothly, using a putty knife or trowel. Allow it to dry completely.

3. Sand the walls: Once the compound is dry, sand the walls to create a smooth surface. Use fine-grit sandpaper and work in circular motions.

4. Prime and paint: Apply a primer to the walls to create a base for the paint. Once the primer is dry, paint the walls with a color of your choice. Use a roller for larger areas and a brush for corners and edges.

By following these steps, you can effectively eliminate seams in mobile home walls and achieve a seamless and finished look.


Removing the seams in mobile home walls can make the rooms appear larger and more complete. Mobile home manufacturers cover the walls with vinyl board panels and secure them in place with battens. Contractors refer to the battens that cover the seams as “batts.” To eliminate the seams in mobile home walls, you need to remove the batts and use a plaster product or joint compound with drywall tape.

Step 1

Start by removing the battens from the seams. The battens are held in place over the seams with brads or tacks. Begin at the bottom of the wall and insert the blade of a putty knife between the batten and the wall. Twist the blade towards you to loosen and remove the batten. Repeat this process all the way up the wall.

Step 2

Ensure that the exposed seams are free from dust and dirt by sweeping them clean. This will ensure that the seam tape bonds securely to the surface.

Step 3

Apply fiberglass tape over each seam. This type of seam tape has adhesive backing, allowing you to tape the seams before applying joint compound.

Step 4

Cover the taped seams with joint compound, also known as “mud.” Hold the putty knife at a 45-degree angle and spread a thin layer of mud over the tape. Smooth out any rough spots or ridges in the mud and allow the joint compound to dry.

Step 5

Use medium-grit sandpaper to eliminate any surface blemishes in the dried mud. Once the surface feels smooth to the touch, apply another layer of joint compound and allow it to dry.

Step 6

Prepare the surface of the dried mud for finishing by sanding it down one final time. Then, choose a wall covering such as paint or wallpaper to apply over the seams.
