Foam Rollers

A 4" foam roller can be a handy tool in composite fabrication for applying various materials such as resins, adhesives, and coatings. It is essential to choose the appropriate roller density and ensure it's compatible with the materials being applied. The closed cell foam of this roller and roller covers ensure you are not wasting material on the roller.

Additionally, proper techniques, such as maintaining consistent pressure and avoiding overworking the resin, is crucial for achieving quality results.

  1. Resin Application: Foam rollers are commonly used to apply resin onto composite materials like fiberglass cloth or carbon fiber fabric during layup. The foam roller helps evenly distribute the resin across the surface, ensuring proper wet-out and bonding between the layers of reinforcement.
  2. Laminating: When laminating composite layers, a foam roller can be used to consolidate the layers and remove air bubbles or excess resin. Roll the foam roller gently but firmly over the composite surface to press the layers together and ensure good adhesion.
  3. Vacuum Bagging: In vacuum bagging processes, a foam roller can be used to assist in consolidating the composite laminate before sealing it under vacuum. Roll the foam roller over the vacuum bag to remove any trapped air and ensure proper resin distribution before initiating vacuum pressure.
  4. Fairing Compounds: Foam rollers are also useful for applying fairing compounds or fillers onto composite surfaces to achieve smooth and uniform finishes. Roll the foam roller over the applied fairing compound to spread it evenly and blend it into the surrounding surface.
  5. Topcoat Application: When applying topcoat finishes or gelcoats onto composite parts, a foam roller can help achieve a smooth and streak-free finish. Roll the foam roller evenly over the surface to distribute the topcoat material, ensuring uniform coverage and thickness.
