MARINE MATERIALS

Materials We Offer

- Resin -

At Hull Marine Supply, we stock a full lineup of top-tier resins to suit every level of boat-building—whether you're crafting structure or just finishing a repair.

  • Premium Isophthalic Polyester Resin
      Ideal as a structural and barrier coat. Highly resistant to water absorption and blistering, with better chemical & secondary bonding properties than standard ortho

  • Vinylester Resin
      Stronger and more durable than polyesters, with superior fatigue and impact resistance. Great for chemical resistance and osmosis protection—widely used in boat hulls and repair

  • Epoxy Resin
      The gold standard for strength and adhesion. No styrene, outstanding mechanical properties, and best for structural lay‑ups. Perfect for high‑performance builds or repairs

  • Catalysts & Initiators
      We carry the essential hardeners for precise curing of each resin type—ensure correct ratios and avoid safety issues.

- Core Materials -

Build durable, dimensionally stable boats with our selection of structural cores:

  • Marine Plywood
      Classic, waterproof timber core—ideal for hulls, decks, and stringers.

  • Coosa Board®
      Fiberglass-reinforced wood composite—lightweight, rot-resistant, and offers great bond strength for applications like decks and hatches

  • High‑Density Closed‑Cell Foams (various thicknesses)
      Lightweight and easy to shape—perfect for flotation cores. Compatible with polyester, vinylester, and epoxy systems

- Fiberglass -

We stock high-quality fiberglass reinforcements perfect for structural strength and finishing:

  • Woven Roving

    • 24 oz and 18 oz rolls, 50″ width — ideal for building thick, durable laminates (hulls, stringers, decks)

  • Chopped Strand Mat (CSM)

    • ¾ oz, 1.5 oz, and 3 oz mat — great for filling grooves, adding bulk, and smoothing finish layers

  • Biaxial Cloth (50″ width)

    • 1208 (12 oz), 1708 (17 oz + ¾ oz mat), and 3610 — double-direction fabric; excellent for strength, stiffness, and corner conformity

  • Special Orders & Custom Cuts

    • Fiberglass slit into tapes (e.g., 8″, 10″, 12″) or custom widths—great for tabbing, fillets, or localized patching.

- Paint & Coatings -

Seal and protect your finish with professional-grade gel coats and epoxy coatings:

  • Gel Coats (Polyester or Vinylester)
      Available in various sizes, with custom color options. Use waxed or unwaxed types depending on your curing method.

    • Aerosol Fillers — fast-setting, easy-to-use spray options.

    • Talc Powder — classic lightweight filler/additive.

    • 3M & Q-CEL Micro Balloons — ideal for fairing, gap-filling, and feathered transitions.

    • Milled Fibers — boost strength in thickened epoxy or resin mixes.
