Z-Poxy Finishing Resin
Premium Lightweight Laminating & Finishing Epoxy
Z-Poxy Finishing Resin is a professional-grade, two-part epoxy engineered specifically for laminating and surface sealing. Its thin, low-viscosity formula allows it to flow easily, making it the premier choice for fibre-glassing airframes, sealing boat hulls, and preparing wood surfaces for a flawless paint finish. Unlike many resins, it remains resilient and will not become brittle over time.
Why Professional Builders Choose Z-Poxy Finishing Resin:- Superior Wicking: The thin consistency is perfect for saturating fibre-glass cloth without adding unnecessary weight.
- Fuel-Proof & Weatherproof: Provides an impenetrable barrier against petrol, glow fuel, and moisture—essential for engine bays and hull interiors.
- Excellent Sanding Qualities: Cures to a hard, level surface that sands beautifully between coats for a mirror-smooth finish.
- Antique Wood Finish: Dries with a subtle golden hue, making it a favourite for woodworkers looking to create an antique aesthetic.
The ultimate solution for "glassing" the centre section of a wing or an entire airframe. It is also the gold standard for sheeting foam wing panels. For RC boat builders, it provides a completely watertight seal for hulls, both inside and out, protecting against the elements and fuel spills.
Woodworking & Outdoor ToolsUse it to weatherproof outdoor wooden furniture or tool handles. Because it penetrates deep into porous grain, it acts as a structural sealer. On decorative projects, it can be layered to build a deep, protective gloss that resists UV and moisture damage.
Pro-Tips for a Flawless Finish- Mixing Ratios: Mix at a strict 1:1 ratio by volume in a clean plastic cup. Ensure you blend the two parts thoroughly for at least 60 seconds to guarantee a proper cure.
- Surface Levelling: On very porous wood, the resin will soak in. Apply multiple light coats, allowing each to cure and sanding with fine-grit paper between applications until the surface is level.
- Easy Clean-Up: If you have any uncured or unmixed resin on your tools or hands, it can be cleaned away using isopropyl alcohol or denatured alcohol.
- Small Batches: Only mix what you need for the immediate task. Once combined, the chemical reaction begins and the excess cannot be stored for later use.
