A truck bed cap is an essential accessory for many truck owners, providing extra cargo space and protection from the elements. However, the added protection from a cap can quickly be undone if you don’t take the necessary steps to ensure it is properly waterproofed. Fortunately, waterproofing a truck bed cap is a relatively simple process that requires only basic materials and tools.
The first step in waterproofing a truck bed cap is to clean the surface thoroughly. Any dirt or debris should be removed with a mild detergent and warm water; avoid using any harsh chemicals or abrasives as they can damage the finish of the cap. Once cleaned, allow the surface to dry completely before proceeding.
Next, prepare your sealing material. There are several types of sealants available specifically designed for use on truck bed caps, such as waxes and polyurethane sealers. Your choice of sealant may depend on your preference as well as the type of material your bed cap is made out of.
Once you have your sealing material ready, it’s time to apply it to your truck bed cap. Start by applying a thin layer using either an applicator brush or roller, making sure to get into all crevices and corners. For best results, apply two or three thin coats instead of one thick one.
Allow Adequate Drying Time
No matter what type of sealant you choose to use for waterproofing your truck bed cap, make sure that you allow adequate drying time between each coat. This will ensure that each layer has properly bonded before adding another one on top.
Apply Protectant
Once all layers have been applied and have had adequate time to dry, you may want to apply a protectant such as wax or silicone spray in order to further protect against moisture damage. This step is optional but can provide added protection.
Conclusion
Waterproofing a truck bed cap is a relatively simple process that requires only basic materials and tools. Start by cleaning the surface with mild detergent and warm water followed by applying multiple layers of sealing material such as waxes or polyurethane sealers. Allow adequate drying time between each layer before finally applying an optional protectant such as wax or silicone spray for added protection against moisture damage.
