But what happens when it starts to show its age? Can you paint fiberglass RV? The answer is yes – but there are some things you need to know before you get started.

In this blog post, we will discuss the process of painting a fiberglass RV. We’ll also provide some tips for making the job go as smoothly as possible.

So if your RV could use a little TLC, read on!

Can You Paint Fiberglass Rv?

Painting a fiberglass RV initially labor-intensive as you prepare the exterior to prime and paint.

Once this step is completed, applying primer and painting is an easy process. You’ll require some time to complete the task.

Repairs need to be cured as well as the primer and paint should dry between each step.

Assuming your RV is in good condition and just needs a new paint job, you’ll want to take the following steps:

Wash and clean the surface. This step is critical as any dirt, grim or wax will prevent the primer and paint from adhering to the surface.

Use sandpaper to lightly sand down the RV. This will help create a smooth texture for painting.

Apply primer to the RV. Primer provides a barrier between the paint and RV surface.

Allow time for the primer to dry before painting. Depending on the type of primer used, this could take anywhere from an hour to 24 hours.

How do I get a smooth finish on gelcoat?

The fiberglass’s surface using 1,000 grit the sandpaper. Sanding the fiberglass can help smooth any bumps within the gelcoat. If you’re sanding a huge fiberglass surface, such as an hull on a vessel you can use the random orbit sander in order to make the process faster.

After you’re finished sanding, use a tack cloth in order to remove all the dust from the surface.

If there are any cracks, crazing or deep scratches within the gelcoat you will need to repair these before you begin painting.

Once repairs have been made and the surface has been cleaned, it’s time to start painting! You can use a brush, roller or spray gun to apply paint to the fiberglass surface. Choose a high-quality marine paint for best results.

Apply several thin coats of paint, allowing each coat to dry completely before applying the next. Sand lightly between each coat with 600 grit sandpaper for a smooth finish.

Finish up by polishing the gelcoat with rubbing compound and wax.

Can you paint over RV walls?

It’s worth it! The majority of interior walls in RVs are made of luan plywood with wallpaper textures glued to the sheets, which you do not want to take off but you are able to paint over.

The bathroom or kitchen walls could be covered with a wallpaper border over this that is able to be removed.

The walls are not the only thing that you are able to paint, your cabinets can be as well. It is a very big job but if done right it can make your RV feel like home.

We have painted the inside and outside of many RVs and fiberglass RVs are no exception! If you take your time to prep the surface and use the proper products, your new paint job will last for years.

If you decide to tackle this project yourself, we suggest using a high-quality acrylic latex paint such as Sherwin Williams Pro Classic or Benjamin Moore Advance.

These paints will adhere well to the glossy surfaces and hold up over time.

What is the difference between paint and gel coat?

What is the difference between paint and gel coat? The gelcoat layer is typically more dense than paint, and is designed to shield the fiberglass beneath and also create a smooth, shiny appearance.

Gelcoat can be pigmented or clear. Paint is typically a thinner layer applied over the gelcoat (or directly to the fiberglass in some cases), and is used to achieve a specific color or design.

Paint can also be applied for extra UV protection.

So, while paint and gel coat serve similar purposes, they are quite different in terms of application and properties.

If you’re trying to decide which one to use for your project, it’s important to keep these differences in mind.

Can you paint directly over fiberglass?

Fiberglass is a difficult material to paint over because it requires to be prepped and primed to adhere on the substrate. Zinsser’s Bullseye’s 2-3-2 is the best primer for fiberglass since it is an ideal key for topcoats.

Zinsser’s also has a Shellac-Base primer that will stick to any surface without the need for a topcoat. This is the best option if you’re painting over fiberglass.

If you have to paint over fiberglass, make sure that you follow these steps:

First, sand the surface with 120-grit paper until it’s dull and then wipe it clean with a tack cloth. Next, apply a coat of primer designed for use on glossy surfaces or for painting over bare metal and allow it to dry completely.

Finally, once the primer is dry, paint your topcoat color in light even coats, allowing each one to dry completely before applying the next. Fiberglass can be a difficult material to paint over, but by following these steps, you’ll be sure to get a beautiful and long-lasting finish.

How do you paint a vinyl camper wall?

Step 1: Prep The Walls For Paint. If you’ve completely gutted the walls of your RV, or simply want the opportunity to paint it with a new paint job, you’ve likely have some flaws in the walls.

Step 2: Tape Off Windows and Doors.

3. RV Paint – Make sure you use the correct primer!

Step 4: Now it’s time to paint!

Paint one section of the wall at a time, starting at the top and working your way down. Use even strokes and paint in the same direction.

I like to use a small roller because it cuts down on brush strokes. Allow each section to dry completely before moving on to the next one.

And that’s it! You now have beautiful, freshly painted walls in your RV! Just be sure to follow all manufacturer’s instructions when choosing your paint and primer, as well as taking proper ventilation into consideration.

Can you paint a gel coat RV?

To effectively paint the fiberglass of a motorhome it first needs to be prepped properly by sanding the surface, which allows that final coating to be able to adhere on the substrate. The surface is then sprayed with a special gelcoat paint.

The type of paint and the application method will be dependent on the make, model, and year of your RV. You should always consult with a professional to get the best results.

If you are considering painting your RV yourself, there are a few things you need to know first. You’ll need to use a gelcoat paint, which is different from regular automotive paint.

Gelcoat is designed to give fiberglass a glossy finish and protect it from UV rays, scratches, and other wear and tear.

It’s also thicker than regular paint, so it needs to be applied with a special spray gun. And because it’s thicker, gelcoat can be difficult to work with if you’re not used to painting cars or RVs.

What kind of paint do you use on an RV?

Many RV owners recommend regular paint for their RV’s exterior. Others suggest Marine deck or marine epoxy.

You’ll need a paint designed for outdoor use that will be able to easily grip the surface of your RV.

To paint aluminum exteriors of your RV apply oil-based or acrylic-latex paints.

For fiberglass or gelcoat surfaces, use a marine paint. If you’re unsure of what type to get, ask the workers at your local hardware store for guidance.

After you’ve chosen your paint, it’s time to prep the surface of your RV. You’ll want to clean it thoroughly with soap and water before beginning to sand down any rough spots.

Once the surface is smooth, apply a primer designed for the type of paint you’ve chosen. Allow the primer to dry completely before moving on to painting.

Can you paint gel coat over paint?

Gelcoat is not recommended to be used over paint, metal, wood or concrete. It will usually not stick to these surfaces.

If you want to use gelcoat, you should remove the paint or other material first. Otherwise, the gelcoat will not last as long as it could and may peel off.

If you are set on using gelcoat over another material, you should roughen up the surface first.

This will help the gelcoat adhere to the surface better. You can use sandpaper or a wire brush for this task.

Once you have roughed up the surface, clean it off with soap and water. Then, apply a primer specifically made for gelcoat.

Finally, apply your gelcoat following the manufacturer’s instructions.

Can you use regular paint in an RV?

Like painting the interior of a home it is possible to use latex paint for the RV’s interior. By using paint with primer, it will help you save time.

Utilize a cut-in brush to smooth out the edges, and then use the help of a roller to smooth those strokes.

Don’t forget to add a second coat for more even coverage. The exterior of the RV can be painted with either acrylic or enamel paint.

If your RV is fiberglass, then you will want to use an acrylic latex paint that has been formulated for fiberglass. If your RV is not fiberglass, then you will want to use an oil-based enamel paint.

Again, remember to add a second coat! After all of that work, enjoy your new-looking RV!

Before painting always consult the manufacturer’s instructions first as they may have different recommendations.

Also make sure that you thoroughly clean and sand the surface before applying any paint as this will help the paint adhere better and create a smoother finish.


So, can you paint fiberglass RV? The answer is a resounding yes!

You just need to use the right type of paint and make sure that you take the necessary precautions.

By following these simple steps, you can give your RV a brand new look in no time.
