KBS Patch: UV-Activated Fiberglass Repair Patch That Cures in Minutes

• Engine and fuel components — gas tanks, fuel lines, radiators, and rusted-through areas.
• Marine and outdoor decking — decking, fenders, and drain pipes exposed to constant moisture.
• Water and sanitation lines — water tanks, PVC pipes, drainage lines, and sanitation systems.
• Plastics and composites — most plastics, Plexiglas, and fiberglass (not compatible with polypropylene).
• Metal and wood — sheet metal, gutters, switch boxes, fences, and wood surfaces.
• Concrete and masonry — steps, roofs, and other concrete repair areas.

• No mixing required: KBS Patch is a single-component sheet, ready to apply straight from the pouch.
• UV or sunlight cured: Cures in 3 to 5 minutes in direct sun, or 10 to 20 minutes under a KBS UV Light.
• Waterproof seal: Creates a watertight bond that will not rot or rust.

• Drillable and paintable: Can be drilled, tapped, sanded, and painted within 1 hour of curing.
• Chemical and solvent resistant: Withstands exposure to many common chemicals, solvents, and oils.
• No shrinkage or expansion: Holds its shape during application and after full cure.

• Wide temperature range: Rated from -30 F to +365 F once cured.
• High strength: Rated to 200 to 500 PSI, suitable for pressurized lines and tanks.
• Reusable pouch: Unused portions can be returned to the UV-protected pouch for later use.

Before KBS Patch: Prep the Surface

For the strongest bond, clean and prep the repair area before applying KBS Patch.

Step 1 — KBS Klean

Removes grease, oil, grime, and road film without leaving residue.

Step 2 — RustSeal (rusted metal only)

Apply two coats and let cure 24 hours, then scuff with 300 grit before patching.
