Product Information
Full details
This guide is for composite material fabricators working with GRP/fibreglass resins and matting. The Bubble Buster Roller (V Notch Roller) significantly improves resin impregnation and air removal, leading to stronger, more durable finished parts. Its primary caveat is its specific application for hand lay-up processes. Key features include its lightweight aluminum construction, unique V-notch and fin design for efficient resin distribution and air bubble reduction, and compatibility with acetone for cleaning.

FAQs
What is the main advantage of the V-notch design?
The V-notch design helps to break the surface tension of the resin, allowing trapped air to escape more easily and improving the impregnation of the glass fibers.
Can this roller be used for epoxy resins?
While primarily designed for GRP/fibreglass resins, it can often be used with epoxy resins for hand lay-up. However, it is always recommended to test compatibility with specific resin systems.
How often should I clean the Bubble Buster Roller?
The roller should be cleaned thoroughly after each use, before any resin cures on its surface, to maintain its effectiveness and longevity.
What is the difference between this and a standard finned roller?
This roller combines the air-relief properties of finned rollers with the superior glass fiber impregnation of a paddle roller, thanks to its unique V-notch and fin configuration.
What are the dimensions of the roller head?
The roller head dimensions are 50mm in width and 40mm in depth/height of the fins/notches.
Is this roller suitable for spray-up applications?
No, this roller is specifically designed for hand lay-up processes and is not intended for spray-up applications.
What material is the roller made from?
The roller is constructed from lightweight aluminum.
Troubleshooting
Roller leaves streaks or uneven resin coverage
Ensure the roller is clean and free of hardened resin. Apply consistent, even pressure during rolling.
Air bubbles still present after rolling
Make multiple passes over the affected area. Ensure the roller is making full contact with the matting and resin. Consider if the resin is too thick or not applied generously enough.
Resin not impregnating the matting effectively
Verify that enough resin has been applied. Ensure the roller is not pushed too hard, which can compact the matting, or too lightly, which won't encourage impregnation. The V-notch design helps, but adequate resin is still key.
Difficulty cleaning the roller
Clean the roller immediately after use while the resin is still wet. Use sufficient acetone and a brush if necessary to dislodge stubborn residue. If resin has cured, try soaking in fresh acetone.
Pros and Cons
Pros
- Efficiently removes air bubbles, leading to stronger composite parts.
- Distributes resin evenly, ensuring thorough glass fiber impregnation.
- Lightweight design reduces user fatigue.
- Versatile design combines benefits of different roller types.
- Easy to clean with common solvents like acetone.
Cons
- Primarily designed for hand lay-up applications, not automated processes.
- V-notch design may be less effective on very thick or complex matting compared to specialized rollers.
- Requires regular cleaning to maintain optimal performance.
- Aluminum construction, while lightweight, may be less rigid than steel alternatives.
- Not suitable for use with all resin types without testing.
Setup, Compatibility & Care
Setup: The Bubble Buster Roller is ready for immediate use upon unboxing. Ensure it is clean before its first application.
Compatibility: This roller is designed for use with standard GRP/fibreglass resins and various types of fibreglass matting. It is suitable for hand lay-up processes. Always check resin manufacturer guidelines for compatibility with tools.
Care: After each use, thoroughly clean the roller to prevent resin from curing on the fins and notches. Acetone is the recommended solvent for cleaning. Immerse or wipe the roller with acetone to dissolve and remove uncured resin. Store in a clean, dry place away from direct sunlight.
