How Can We Help?
Can I apply bed liner to my white ABS camper roof?
Can SL&C brand coatings be applied to my RV ABS roof? I need white or a light grey coating.
If you are planning to stick with the White color, be aware most White colors discolor with long-term UV exposure. We have an aliphatic polyurethane coating which should be used as a final coat. The polyurethane coating can’t be applied as a thick bed liner type product, so it is usually recommended for the final coat only.
We usually suggest DIY applicators start by applying the base coat of our bedliner in a light grey color using our standard liquid and powder combination. After the base coat is sprayed but not fully cured, a top coat of our White bedliner is applied to get a thick scratch resistant coating. Once the finished product is fully cured, we suggest an application of our marine grade White polyurethane be applied for the long term care.
Standard Grey or Black coatings only require the base coat application. Other custom colors don’t generally need the polyurethane top coat, but it can help ensure better lasting protection.
For recommended thickness, we would suggest you estimate about the same thickness as a standard duty spray in bed liner application if you plan to walk the surface. The mil height would be about 60 mils using this guideline. If you just need a good overall protective coating, you could apply as thin as 30 mils and still get exceptional protection.
If you plan to go the DIY route and apply these coatings yourself, just be aware that most products on the market are less than 100% solids. This means you often have to use as much as double the product to achieve the same thickness. Most coatings dry in part by evaporation, and lose volume in the process rather than cure like ours.
NOTE: It’s advisable to prepare your surface by light sanding with 180 grit, and using an adhesion promoter or primer for plastics first.
