CRC All Purpose Resin 1.25L Durable Epoxy For Marine Decking Bonding And DIY Repairs

CRC All Purpose Resin 1.25L is a robust sheathing and laminating resin engineered for extreme durability in marine and general applications. Trusted by professionals, it forms a tough, stable base for paints and varnishes while delivering superior bonding, penetration, and barrier properties across surfaces.

Why it stands out

• Low mixed viscosity for excellent penetration and wet-out at ambient temperatures
• Extremely strong, moisture‑resistant bonding and effective barrier coating properties
• Thickens with micro balloons to bridge gaps and voids; can be sanded and shaped after cure
• Does not shrink after curing; formulated without volatile solvents, with a relatively high flash point and low odor
• Bonds to a wide range of surfaces—wood fibre, fibreglass, reinforcing fabrics, foam, and various metals
• Neat formulation can act as an osmosis barrier coating on most boat hulls
• No thinning required; ready to use straight from the container

Versatile uses that solve real needs

Whether you’re building a boat, waterproofing timber, or tackling automotive and general construction projects, this resin delivers dependable performance. When paired with fibreglass cloth, it serves as a moisture barrier on wooden boat hulls, creating a durable surface that accepts paints and varnishes consistently.

• Boatbuilding: hull protection, moisture barrier, and structural reinforcement
• Waterproofing: seals joints, seams, and timber surfaces to guard against moisture ingress
• Automotive repairs: suitable for fiberglass and composite components
• Building and decking projects: durable, stable base for coatings and finishes

How this resin adapts to your project

Use neat as an osmosis barrier coating on most boat hulls to prevent moisture migration. When gaps or voids exist, thickening with micro balloons bridges the space, providing a solid, sandable surface once cured. Its low odor and high flash point make it practical for enclosed spaces, while its strong bonding properties keep substrates secure over time.

Practical application tips

• Apply in clean, dry conditions without thinning to preserve its penetrating performance
• For gaps and voids, mix with micro balloons to create a stable fill that cures smoothly
• Allow full cure before sanding or shaping for a seamless finish
• Compatible with wood, fibreglass, reinforcing fabrics, foam, and many metals
