Product Information
Full details
The Cromar Ribbed Metal Roller (225mm x 40mm) is designed for professional laminators and DIY enthusiasts working with composite materials who need a reliable tool to ensure structural integrity and a flawless surface finish. Its primary benefit is the efficient consolidation of resin into fiberglass matting while achieving an optimal 3:1 resin-to-mat ratio and eliminating trapped air, though its rigid metal construction requires diligent cleaning to prevent resin buildup and ensure long-term functionality.

FAQs
Can I use this roller with epoxy resin?
Yes, this metal roller is compatible with most epoxy and polyester resin systems.
How do I clean this after use?
Clean immediately after use using an appropriate solvent like acetone to ensure all uncured resin is removed from the ribs.
Is the handle replaceable?
The roller is designed as a complete unit, but standard handles are often compatible if the cage size matches the roller internal diameter.
Will the metal ribs damage delicate fabrics?
While effective on heavy fiberglass matting, use a light touch on delicate fabrics to prevent fiber displacement.
Why is the 3:1 ratio important?
A 3:1 resin-to-mat ratio provides the best balance of structural strength and weight for composite parts.
Troubleshooting
Roller is sticking to the fiberglass matting
Ensure the roller is slightly wet with resin before contact; if the resin is curing too fast, adjust the catalyst ratio.
Resin buildup inside the ribs
Soak the roller head in an appropriate resin solvent for a short period, then use a stiff (non-metal) nylon brush to dislodge the material.
Pros and Cons
Pros
- Durable metal construction resists chemical degradation
- Effective at removing air voids in thick laminate layers
- Generous 225mm length speeds up coverage on large parts
- Promotes a professional, smooth finish on cured surfaces
Cons
- Metal rollers are heavier than plastic alternatives
- Requires thorough solvent cleaning to prevent permanent resin curing on the surface
- Less effective on tight, complex curves compared to smaller diameter rollers
Setup, Compatibility & Care
Before starting your project, ensure the handle is securely attached and moves freely. This roller is compatible with most standard polyester and epoxy resin systems. After use, cleaning must occur immediately before the resin hardens. Use an appropriate solvent—such as acetone—to dissolve uncured resin from the ribs. Once the residue is removed, wipe the roller dry and inspect the metal for any remaining hardened particles. Store the roller in a clean, dry area away from direct sunlight and extreme temperatures. Avoid using metal scrapers to clean the ribs, as this can nick the surface and interfere with the roller's ability to distribute resin smoothly.
