Custom Shop Urethane Spray-On Truck Bed Liner Kit Black 1 Gallon — Includes Spray Gun & Regulator, 3:1 Mix

Custom Coat Black 1 Gallon is a professional two-part urethane spray-on truck bed liner kit that delivers a durable, textured protective coating with a simple 3:1 mix and included spray gun and regulator.

This all-in-one kit contains concentrated base, standard hardener, and a purpose-built applicator to give you a resilient, non-slip finish for truck beds, trailers, bumpers, garage floors, and more. Formulated for flexibility and abrasion resistance, the coating is heat-, UV-, and water-resistant so it helps preserve surfaces against corrosion and wear while dampening noise and vibration. The package covers roughly 110–130 square feet at a 10 mil wet film thickness and is designed to produce professional results in a DIY-friendly setup.

How do I mix and apply the Custom Coat kit?

Mixing is straightforward: combine three parts base to one part hardener, stir, then load the supplied spray gun. Shake briefly after mixing, test spray for consistency, and apply in even passes for an even textured finish. Clean the gun promptly after use to avoid cured residue.

• Kit contents: four 24 fl. oz. base cans, four 8 fl. oz. hardener cans, applicator gun with regulator
• Mix ratio: 3 parts base : 1 part hardener by volume
• Coverage estimate: 110–130 sq ft at 10 mils wet film thickness
• Application tips: maintain 6–12 inches from surface and overlap passes

What surfaces can I coat and how durable is the finish?

Custom Coat adheres to metal, wood, concrete, and many composites, making it suitable for truck beds, frames, ramps, decks, and garage floors. The cured urethane forms a flexible, impact-resistant textured layer that fights chipping and abrasion while tolerating temperature changes and outdoor exposure.

• Common uses: truck beds, trailers, chassis, bumpers, tool boxes, stairs, docks
• Performance: abrasion and impact resistant, flexible to resist cracking
• Environmental resistance: UV-stable, heat-tolerant, water-resistant
• Acoustic benefit: helps reduce vibration and road noise when applied

How much preparation and curing time should I expect?

Surface prep is essential: clean, degrease, and scuff or sand glossy areas for adhesion. Drying and cure depend on temperature and film thickness; allow tack-free time then full cure before heavy use. Higher humidity and lower temperatures extend drying and curing times.

• Prep: remove grease, rust; sand to a dull profile; wipe with solvent
• Dry times: tack-free in hours (varies with conditions), handle gently after 24–48 hours
• Full cure: typically several days depending on climate and thickness
• Clean-up: flush applicator and lines with appropriate solvent before cure

Can I tint the kit or change texture?

Yes — Custom Coat offers urethane tint concentrates and additional kit sizes to create custom colors or multi-tone patterns. Texture is controlled by spray technique and film thickness; adjust nozzle distance, pressure, and passes for finer or coarser finishes.

• Color options: tint concentrates available in 50+ colors
• Texture control: modify spray distance and overlap for desired profile
• Kit choices: other sizes available from quart to multi-gallon kits
• Application methods: spray gun included; roller kits available separately

Who this is for: This kit suits hands-on vehicle owners, fleet managers, restoration specialists, and DIYers who want a long-lasting, professional textured coating without contracting out. It’s ideal for anyone protecting metal or concrete surfaces from abrasion, weather, and everyday wear while keeping noise and vibration under control. If you need a flexible, impact-resistant finish with options for color and texture control, this Custom Coat 1 gallon spray-on urethane kit is built for that purpose.
