Handicap Van Topper Painting: A Step-By-Step Guide

Painting a fiberglass handicap-accessible van topper is a rewarding project that can be done at home. It requires some technique and skill, but with the right tools and preparation, you can achieve great results. The process involves cleaning and preparing the surface, using fillers and primers, and then applying several coats of paint and clear finish. It's important to take your time and work in steps to ensure a smooth and professional finish. The cost of materials can vary, but it's important to use good-quality paint and clear coat to ensure the paint job lasts.

Prepping the surface

Cleaning and Washing:

Start by thoroughly cleaning the surface of the van topper. Use a pressure washer with soapy water to remove any dirt, grime, or debris. Scrub the surface well and then rinse it with clean water. This step ensures that the surface is free from any contaminants that might interfere with the painting process.

Sanding:

Once the surface is clean and dry, it's time to sand it. Sanding creates a rough texture on the surface, which helps the paint adhere better. Start with a lower grit sandpaper, such as 200-grit, to scuff the surface and create a profile for the paint to grip. Focus on sanding evenly across the surface, especially if there are any existing coatings or imperfections. After sanding, wipe down the surface with a solvent to remove any dust or residue.

Filling and Repairing:

Inspect the surface for any chips, cracks, or imperfections. If there are any damaged areas, use a suitable filler or putty to repair them. For fiberglass repairs, products like Bondo Glass, Evercoat's Gel-Kote, or epoxies from JB Weld that dry white can be effective. Apply the filler in layers, following the product instructions, to achieve a smooth and even finish.

Priming:

Before painting, it's essential to apply a primer. Primers provide a base coat that promotes better paint adhesion and helps the paint job last longer. Choose a primer color that complements the original color of the topper and your desired paint color. For a blue truck and a red topper, consider using a grey or black primer for a smooth transition. Apply the primer evenly across the surface, following the manufacturer's instructions for the best results.

Wet Sanding:

After applying the primer, you may want to consider wet sanding to achieve an ultra-smooth finish. Use fine-grit sandpaper, such as 2000-grit, and lightly sand the primed surface. This step helps to remove any minor imperfections and creates an even smoother base for the paint to adhere to. Remember to work in light passes to avoid damaging the primer coat.

Remember, taking your time with each step and properly preparing the surface will yield the best results. Don't rush the process, and always refer to product instructions and safety guidelines when working with paints and solvents.

Painting techniques

Painting a fibreglass handicap-accessible van topper requires some preparation and technique. Firstly, it is important to clean the surface thoroughly. This can be done using soapy water and a pressure washer to remove any dirt or grime. Next, use a solvent to wipe down the surface, followed by a light scuff with grit sandpaper to create a rough surface for the paint to adhere to. It is recommended to use 200-grit sandpaper for this step.

After the initial preparation, it is important to choose the right type of paint. For a fibreglass topper, spray paint is often used, specifically a primer and paint combination. It is recommended to apply several light coats rather than one heavy coat to achieve a smooth and even finish. This process may require some practice and patience to master.

When applying the paint, use a steady hand and maintain a consistent distance from the surface to avoid an uneven finish. It is also important to work in a well-ventilated area or wear a respirator to protect yourself from paint fumes. Allow each coat of paint to dry thoroughly before applying the next one.

For a professional finish, consider using a clear coat after the final coat of paint. This will add shine and protection to the paint job. Again, apply the clear coat in light coats to achieve the best results.

If you are not confident in your painting skills, it may be worth considering a paint/body shop to get a high-quality finish. However, this can be more expensive.

Repairing fiberglass

Painting a fibreglass handicap-accessible van topper involves a few key steps. Firstly, it is important to clean the surface with soapy water and a pressure washer, scrubbing thoroughly. After washing, wipe the surface with a solvent. Next, use a grit (such as 200-grit) to scuff the surface and create a rough texture for better paint adhesion. Repeat the washing and solvent-wiping process, then apply primer and paint, preferably in light coats. Finally, apply a clear coat for added protection and shine.

Now, repairing fibreglass is a separate process that requires careful handling due to the hazardous nature of fibreglass. It is crucial to wear protective gear, including a respirator, gloves, safety glasses, and a paint suit to prevent skin, eye, and lung exposure to fibreglass particulate. When repairing fibreglass, the number of layers of fibreglass cloth and the thickness of the patches depend on the thickness of the fibreglass shell being repaired. For a 1/8" wall, for instance, three layers of fibreglass material are recommended, with the largest patch extending beyond the hole and subsequent patches decreasing in size.

The repair process involves first identifying and circling the holes and cracks to be patched. Next, use a tool like an angle grinder to grind down the surface around the holes and cracks, tapering it from thick to thin. Before applying the patches, follow the instructions on the container for mixing and using the resin. It is important to maintain a stable temperature of around 70 degrees Fahrenheit and ensure good airflow during the repair process.

When applying the patches, start by painting the area with resin using a paintbrush. Then, coat the largest patch with resin and firmly press it onto the prepared surface. Repeat this process, layering the patches from largest to smallest. Any unwanted resin drips can be cleaned with mineral spirits on a rag before they harden. This repair method can be used for cosmetic and structural fibreglass repairs, extending the life of the fibreglass component and saving replacement costs.

It is worth noting that repairs on fibreglass differ from the original manufacturing process. Repairs rely on secondary bonds with the original primary structure, and the strength of the repair depends on the adhesive quality of the resin. Therefore, it is essential to use a resin that is just as strong as the original resin used in the fabrication. By increasing the surface area of the bond line, you can enhance the strength and durability of the repair.

Primer and base coats

Painting a fibreglass handicap-accessible van topper is a rewarding task that can be completed successfully by following a few key steps. Before applying primer and base coats, it is important to clean the surface thoroughly with soapy water and a pressure washer, scrubbing and then wiping with a solvent. Next, use 200-grit sandpaper to scuff the surface and create a rough texture that will help the paint adhere better. It is recommended to sand with a minimum of 600-grit sandpaper, and many people now use 800-grit for priming. After sanding, wash the surface again and wipe it down with a solvent to ensure it is clean and ready for painting.

When it comes to primer and base coats, the first step is to apply an epoxy to seal the surface. This will create a smooth base for the paint to adhere to. Once the epoxy has dried, use a regular primer over it to fill in any remaining imperfections and create a uniform surface. For the best results, it is recommended to use a grey or black primer, especially if the original colour of the topper is dark, such as red. This will create a suitable base for the final paint colour.

After priming, it is important to plan for several coats of paint to achieve even coverage. Lightly sand between each coat with 2000-grit sandpaper to ensure a perfectly smooth finish. Depending on the desired outcome, you can use spray paint or a paint gun for the base coats. If using spray paint, choose a high-quality product such as Dupli-Color PerfectMatch. Apply the paint in light coats, allowing each coat to dry before applying the next. For a different effect, consider using a paint roller or brush for the base coats, which can create a more textured look.

It is important to note that the type of paint used will impact the final result. A quart of high-quality paint can be expensive, costing almost $100. If cost is a concern, consider using a cheaper paint and investing in a clear coat to protect the paint job and give it a professional shine. Additionally, using an adhesion promoter can help improve the adhesion of the paint to the surface, ensuring a longer-lasting finish.

Clear coats

Preparation: Before applying the clear coat, it is crucial to prepare the surface properly. Start by cleaning the fibreglass surface with soapy water and a pressure washer, ensuring that the surface is thoroughly scrubbed. Next, wipe down the surface with a suitable solvent to remove any remaining grease or grime.

Sanding: After the initial cleaning, use 200-grit sandpaper to scuff the clear coat lightly. This step helps create a rough surface for better paint adhesion. Once you've scuffed the entire surface, wash the topper again and wipe it down with solvent to remove any dust or debris from the sanding process.

Clear Coat Application: When the surface is adequately prepared, you can begin applying the clear coat. For the best results, use a high-quality clear coat product specifically designed for automotive use. Apply the clear coat in light coats, following the directions on the product for proper application techniques and drying times. Typically, 2 cans of clear coat are sufficient for a standard-sized van topper.

Drying and Curing: Allow the clear coat to dry completely according to the manufacturer's instructions. The curing process is critical for achieving a durable finish. Avoid touching or handling the topper during this period to prevent any imperfections in the clear coat.

Sanding and Polishing: Once the clear coat has cured, you may optionally sand it with finer grit sandpaper (320 to 600 grit) to achieve an even smoother finish. After sanding, polish the surface with automotive polishing compound to bring out a high shine.

Maintenance: To maintain the clear coat and keep your van topper looking its best, regular cleaning and maintenance are essential. Wash the topper regularly with mild soap and water, and consider using automotive wax or sealant to protect the finish and enhance its shine.

Remember, clear coats play a vital role in protecting the underlying paint and enhancing the overall appearance of your handicap-accessible van topper. By following these steps and allowing adequate drying time, you can achieve a professional-looking and long-lasting finish.
