Product Information
Full details
This Bubble Buster Roller is designed for professionals and serious DIYers working with GRP/fibreglass resins and matting. Its key benefit is efficient air expulsion and superior resin impregnation, leading to a stronger, smoother finish with less effort. A potential caveat is its specialized design, which may require a slight learning curve for those accustomed to simpler rollers.

FAQs
What is the primary purpose of the V-notch and fin design?
The V-notches and fins work together to effectively push resin through the matting while simultaneously releasing trapped air bubbles. This prevents voids and strengthens the final laminate.
Can this roller be used with all types of fibreglass resin?
Yes, it is designed for general use with most common GRP/fibreglass resins, including polyester and vinyl ester resins, during hand lay-up processes.
How do I clean the Bubble Buster Roller?
Clean immediately after use with acetone. Ensure adequate ventilation when using acetone.
What is the main advantage over a standard finned roller?
This roller combines the air-relieving properties of finned rollers with the superior glass fibre impregnation of classic paddle rollers, offering a dual benefit for improved composite quality.
Is this roller suitable for beginners?
While effective for all users, beginners might benefit from watching demonstration videos to understand the optimal technique for air expulsion and resin distribution.
What are the dimensions of the roller head?
The roller head measures 225mm in width and 40mm in diameter.
What material is the roller made from?
The roller head is constructed from lightweight aluminium.
Troubleshooting
Roller not expelling air effectively
Ensure the roller is moving consistently and with adequate pressure. Check that the V-notches and fins are clear of any dried resin or debris. The resin viscosity might also be a factor; ensure it is within the recommended range for your application.
Resin is not impregnating the matting properly
Verify that the horizontal fins are making good contact with the matting and resin. You may need to apply more resin to the surface before rolling, or adjust your pressure to ensure thorough saturation.
Excessive splashing during use
Reduce the speed of your rolling motion. Ensure the vertical notches are oriented correctly to guide the resin flow rather than fling it outwards. For very large areas, consider a wider roller if available.
Roller feels heavy and causes fatigue
While designed to be lightweight, prolonged use can still be tiring. Take short breaks and ensure you are using a comfortable handle. Proper technique can also reduce strain.
Pros and Cons
Pros
- Reduces user fatigue with its lightweight design.
- Efficiently removes air bubbles for a cleaner finish.
- Minimizes resin splashing for better control.
- Combines benefits of different roller types.
- Durable construction for GRP/fibreglass applications.
Cons
- May require practice for optimal air expulsion technique.
- Specialized design might be overkill for very small projects.
- Not suitable for water-based paints or other non-GRP applications.
Setup, Compatibility & Care
Setup: The Bubble Buster Roller is ready for use out of the box. Ensure it is securely attached to your preferred handle if it is detachable.
Compatibility: This roller is specifically designed for use with GRP/fibreglass resins and matting. It is not intended for use with water-based paints, epoxy coatings, or other non-composite materials.
Care: To maintain performance and longevity, clean the roller immediately after each use. Uncured or partially cured resin can be difficult to remove.
- Immediate Cleaning: While the resin is still wet, use acetone to thoroughly clean the roller. Ensure you are in a well-ventilated area when using acetone.
- Deeper Cleaning: For dried-on resin, a more intensive cleaning with acetone may be required. Agitate the fins and notches carefully to dislodge any hardened material.
- Storage: Store the roller in a clean, dry place, away from direct sunlight and extreme temperatures. Avoid storing it in a way that could damage the fins or notches.
