How to Paint RV Exterior Fiberglass?

If you spend a lot of money on an RV (recreational vehicle), you would expect it to perform well.

The most popular question is “What features should I look for in an RV?” The second option is usually the engine performance and all of the technical aspects. The colour of your RV’s exterior would be the last thing that comes to mind.

However, for some people, appearance is everything.

That isn’t an issue, you want your RV to look nice.

If you don’t like the colour of your new RV because it was popular at any period but isn’t fashionable anymore, or if the paint on your RV has worn down over time and you want to give it a fresh distinctive touch. If your RV’s paint has deteriorated due to age, you have nothing to be concerned about.

Whatever the cause, you can always give your RV a whole new appearance.

Fortunately, the market has everything you’ll need to paint your RV.

Everything, from paints to waxes, palm sanders to painter’s tape, is simple to come by and doesn’t necessitate the transport of your RV to a workshop. It’s a fun process that you can do yourself.

Ensure that you have decent fibreglass paint before getting started. Expert grade fibreglass paint is not only more expensive, but it also provides a superior and more professional finish.

To select a colour, choose from a variety of fibreglass paint finishes matte, gloss, or high-gloss.

Acrylic, polyester, polyurethane, and epoxy paints are more durable since they provide a solid all-weather protective coating. Simply make sure it doesn’t contain melamine or oil.

How Do I Paint My RV’s Exterior?

Preparation for Painting

First, park your RV in a shaded and ventilated area like your driveway or garage. Then, gather all necessary items such as a palm sander, fine-grit sandpaper, denatured alcohol, soft cotton cloth, soap water, and painter’s tape.

Make the exterior fibreglass surface Clean

Clean the RV’s entire external surface using a mild detergent/soap solution, or an automobile sponge to remove any dust, grime, mud, and bird droppings from the surface of your RV. A ladder may be used to access difficult areas on the roof.

Rough up the RV’s surface.

Make sure the fibreglass on your motorhome is roughened up so it can accept and absorb the primer coat and paint. Wet sandpaper with fine-grit may be used to rough up the surface. Don’t hang around for too long at one place, as this may result in uneven final results. This whole operation should take about an hour.

Wipe away any loose dust.

Wipe off the whole sanded surface using denatured alcohol with a rag to remove any remaining grease after washing with detergent water. Cover the not-to-be-painted regions: Use strong paper and painter’s tape to cover anything like knobs, windows, mirrors, and window panes.

The painting stages

Get latex-based primer, fibreglass paint, a paint gun, and acetone on hand before getting started. Painting isn’t as simple as it appears. When painting with a brush or a spray gun, one must be extremely cautious and patient.

If you are not familiar with using a paint gun, hand-painting is an option. Hand-painting, on the other hand, is a time-consuming method that may not result in a smooth and uniform finish. The best solution is to use a Paint-gun. It not only takes less time but also gives an excellent and professional-looking finish. You can buy or rent one before applying it directly to your RV so you can try it out first.

The process is simple once you’ve gotten the hang of it.

Remove any residual paint from the spray gun.

Clean the inner section of the paint gun with a delicate cotton cloth soaked in acetone to eliminate any remnants of previous painting jobs from it, as those may interfere with the current painting.

Make the necessary painting solution.

Following the directions in the user handbook supplied with the kit, mix and prepare a shade of paint that is appropriate for your intended purpose.

Apply a primer coat to the entire surface.

To ensure that the paint adheres properly to the fibreglass, apply a single coat of primer to the outside surface of the RV.

The paint should be loaded into the gun.

Paint guns are available in many brands and various sizes, so you can pick one that suits your needs. Fill the mixture into your paint gun and start sponging on long, smooth strokes of colour. This operation must be done meticulously to avoid any drips or spills. It is best to begin at the front of the RV and work your way back. This ensures a uniform appearance.

Allow the paint to cure fully.

Allow the RV to dry for 24 hours after applying the gel coat. Apply the following day’s coat in the same manner as before. Examine whether every fibreglass surface has been adequately covered and if any particular areas have been left behind, clean it with sandpaper and repaint it.

Last Step

After you’re done, there are still a few more things you can do to improve the look of your RV. All you’ll need is an RV wax and a soft cotton cloth.

Apply a layer of RV wax with circular strokes using a soft cotton cloth. This coating shines and protects the paint layer.

Now that the heavy paper and painter’s tape have been removed, be careful not to peel off the paint surface.

Concluding Remarks

Painting your RV not only gives it a fresh new appearance but also helps to preserve it. What appeared to be an impossible job at first may be completed in small steps with the aid of all necessary equipment.

After you’ve found the paint you wanted for your motor home, the job isn’t finished; you must take excellent care of your van to ensure that the paint lasts longer and allows you to enjoy more recreational trips. If you want your RV to look clean and well-maintained, you should invest time in maintaining the outside as nicely.

Keep an eye on the weather, and be sure that there are no trees or anything else blocking your view. When preparing for a camping trip, make sure you bring plenty of towels and washcloths to keep things clean. To protect it from UV rays, park your RV under shade at all times; wash it frequently to eliminate dirt and bird droppings; and drive carefully avoiding scratches or dents. Take care of your RV and it will reward you with relaxing fun vacations.
