Novol 1225 Fiber - Glass Fiber Reinforced Putty (1.8kg)
Repair structural damage and bridge perforated rust with Novol Fiber. This 1.8kg unit is a heavy-duty polyester putty reinforced with short glass fibers. It is engineered for areas that require high mechanical strength and the ability to fill deep depressions or small holes without the fragility of standard finishing putties.
Fiber acts as a "structural bridge," providing a rigid foundation that resists cracking and vibration, making it the essential first step in repairing weakened body panels.
The Reinforcement System
This is a two-component (2K) structural filler that uses glass fibers to distribute mechanical stress across the repair.
- Included Hardener: Supplied with a dedicated tube of dibenzoyl peroxide paste.
- Mixing Ratio: 100 parts Putty : 2-3 parts Hardener (by weight).
- Consistency: Thick and fibrous; designed for building up volume rather than fine finishing.
Key Features & Benefits
- High Structural Tension: The interlaced glass fibers provide immense tensile strength, allowing the putty to span small holes and cracks without sagging.
- Extreme Filling Power: Can be applied in thick layers to level out deep dents or "shaping" reconstructions.
- Excellent Adhesion: Bonds powerfully to steel, aluminum, and glass-reinforced plastics (GRP).
- Low Linear Shrinkage: Ensures that large repairs stay "true" and flat, preventing the edges of the repair from lifting over time.
- Hardness: Once cured, it is significantly harder than universal putties, offering a rock-solid base for the rest of your bodywork.
Professional Application Strategy
Because Novol Fiber contains glass strands, it requires a specific sanding workflow.
- Preparation: Remove all loose rust and scale. Sand the substrate with P80 to create a coarse mechanical key. Degrease with Novol Plus 780.
- Mixing: Mix the red hardener thoroughly until the green putty has no streaks. Caution: Do not over-mix or "whip" the putty, as this can break the glass fibers and reduce its strength.
- Application: Press the putty firmly into the repair to ensure it "bites" into the metal. Build it up slightly higher than the surrounding panel to allow for sanding.
- Initial Sanding: Use P80 to P120 grit. The glass fibers make this putty harder to sand than "soft" putties, so a DA sander or a long-board file is recommended.
- The "Finishing" Step: Novol Fiber is not a finishing putty; the glass fibers will leave a coarse surface. You must overcoat this with a fine putty like Novol Unisoft (1155) to fill the pinholes and sanding marks before priming.
Expert Insight: Fiber putty is the "foundation" of a repair. If you are fixing a rusted-out wheel arch, use Novol Fiber to get the shape and strength back, then use Novol Unisoft to get the smoothness. Never try to sand Fiber putty to a "paint-ready" finish - it's too coarse for that!
