One of the most popular of all home improvement projects is painting the walls. New paint color can instantly change the entire look of your home. The fact that most painting requires only the skill level of a beginner is an added bonus for your financial bottom line, as doing it yourself is much cheaper than hiring a pro.
But while painting is a very easy project with standard "stick-built" home construction, where the walls are finished with standard gypsum wallboard, it is a little trickier if you live in a mobile home or manufactured modular home, where the walls are made from a different material.
Manufactured homes usually use vinyl-on-gypsum (VOG) wall panels rather than standard drywall. Instead of using tape to cover the seams, as is done with drywall, the joints are covered with batten strips during assembly. Although the way VOG panels are manufactured and installed does complicate the painting job, it doesn't mean you can't paint the walls when you want to update the look.
What is Vinyl-On-Gypsum?
These vinyl-coated walls have a shiny finish, and there is often a printed design layer applied over the gypsum and under the shiny vinyl topcoat. Manufacturers favor VOG panels because they are lightweight and easy to install in factory settings.
Before You Begin
Before you begin painting the walls in your manufactured space, you will need to decide if you want to leave the battens up or remove them. Taking them down and filling in the seams is cumbersome work, but the finished job will look great and appear similar to standard walls in stick-built homes. If you can live with the battens, you can simply paint over them, which makes for an easier painting project that is still a cost-effective update.
You'll need approximately two coats of primer and at least one coat of paint. Make sure you get enough paint with the help of The Spruce's Paint Calculator.

Remove the Battens and Finish the Seams (Optional)
Start by prying out the battens that cover each seam between the VOG panels.
Prepare the taping compound as directed by the manufacturer. With a premixed joint compound, this may involve stirring the compound. Apply a thick layer of compound over the seams between panels, using a 6-inch drywall knife.
Cover the wet compound with strips of joint tape and press it into place with a 4-inch drywall knife. Immediately cover over the tape with another layer of joint compound, applied with the 6-inch knife. Let the taping compound fully dry.
Lightly sand the joint to smooth it down. Be careful not to tear the vinyl coating on the panels as you sand.
VOG panels do not have the tapered edges found on drywall panels, so it's a bit harder to get a seamless finish but still possible. Taping is the best option if you are texturing your manufactured home walls or if you prefer a smooth finish.
Prepare the Walls
Cover the floors and furniture with drop cloths. Clean the walls with a mild detergent or TSP solution and a rag. Go over each surface twice, then finish by wiping down with a fresh cloth dampened with clear water.
Once the walls have dried, use painter's tape to mask the edges along the trim, ceiling, and floor.
If the walls have any kind of damage or holes from nails or screws, fill them with spackle and then sand smooth, following the manufacturer's directions. Again, make sure not to damage the vinyl coating on the wall panels when sanding.
Prime the Walls
The vinyl surface of VOG panels will accept paint better if you first coat them with a good quality acrylic primer.
Applying primer is done like any painting job. Start by using an angled trim brush to cut in the primer along the edges of the wall, then apply the primer to the broad areas using a roller.
Two light coats are best. Make sure the primer dries fully between coats.
Choose the Right Primer
With the shiny surface of VOG panels, all-in-one paint/primer products do not work as well as separate coats of primer and paint.
Paint the Walls
After the primer is fully dry, apply one or two coats of high-quality acrylic latex paint. Again, use an angled trim brush first to cut in the edges, then use a roller to paint the large expanses. If two coats are necessary, make sure the first coat dries fully before applying the second coat.
Choose the Right Paint
Low sheen or flat paint bonds better than high-gloss and is less likely to show imperfections in the walls, but high-gloss paint is often recommended for bathrooms and kitchens, where the walls will need to be washed frequently.
Finish by removing painter's tape and folding up drop cloths.
When painting VOG panels, high-quality primers and paints are recommended; you need maximum adhesion and flexibility. The primer and paint need to bond to the wall, and generic bargain paint simply doesn't have the same adhesion found with premium paints.
A common preparation step when painting walls is to lightly sand the entire surface. Do not do this with VOG panels, since sanding can easily damage the surfaces and ruin the paint job.
