Koch Chemie Gelcoat Ultra Heavy Cut Gh9.01 - Abrasive Compound for Gelcoats and Marine Coatings 1L

Koch Chemie Gelcoat Ultra Heavy Cut GH9.01 - Abrasive Compound for Gelcoats and Marine Coatings 

Discover the pinnacle of surface restoration with Koch Chemie Gelcoat Ultra Heavy Cut GH9.01! This extremely powerful abrasive compound is the most aggressive member of the Koch Chemie Marine Line family and was developed to tackle the most demanding challenges. With GH9.01, you can effectively and quickly remove deepest scratches, extremely oxidized and weathered surfaces, pronounced holograms, and massive yellowing from durable gelcoats and coatings on boats, yachts, caravans, and industrial vehicles.

Thanks to innovative technology and a special, highly homogeneous abrasive, GH9.01 provides unmatched cutting performance (grade 9.5 out of 10), capable of radically transforming even the most neglected surfaces. Despite its immense power, it simultaneously leaves a surprisingly good base gloss (grade 4 out of 10), significantly reducing the time needed for subsequent finer polishing steps. The compound is optimized for minimal dust generation and extremely easy residue removal, ensuring efficient and clean work.

Key Features:

• Highest Cutting Performance (Ultra Heavy Cut): Quickly and reliably eliminates deepest defects, scratches, and strongest oxidation.
• Creates Initial Gloss: Despite extreme abrasiveness, it leaves an acceptable gloss after the first step.
• Minimal Dust Generation: Ensures a cleaner and healthier working environment.
• Easy Residue Removal: Compound residues can be removed easily and effortlessly.
• Silicone-Free: Safe for use in paint shops and on silicone-sensitive surfaces.
• High Grit Stability: Guarantees consistent and reliable cutting performance throughout the entire work session.
• Versatile Application: Ideal for gelcoats, polycarbonates (PC), acrylics (PMMA), and all types of marine, caravan, and industrial coatings.

Usage Instructions:

1. Surface Preparation: Thoroughly clean and degrease the surface before polishing (e.g., with Koch Chemie Silicone & Wax Remover or Panel Preparation Spray). Ensure the surface is dry and cool to the touch.
2. Application:
   • Rotary Polisher: Apply a small amount of compound (size of 2-3 peas) onto a hard foam polishing pad or a lambswool pad. A lambswool pad provides the most aggressive cut.
   • Dual-Action Polisher: Recommended for smaller and more sensitive areas, but a rotary polisher will provide a better cut. Use a hard foam pad.
3. Polishing:
   • Start working at low speeds (e.g., 600-1000 RPM for rotary, level 3-4 for dual-action) on a smaller area (approx. 40x40 cm) to spread the compound evenly.
   • Gradually increase the speed (e.g., 1500-2000 RPM for rotary, level 5-7 for dual-action) and apply light to medium pressure. Work with overlapping passes until the defects are removed.
   • In the final passes, reduce pressure and speed to refine the surface and minimize any potential holograms.
4. Residue Removal: Thoroughly wipe off compound residues with a clean, dry, and soft microfiber cloth.
5. Subsequent Steps: For a perfect finish and to remove any remaining holograms or fine scratches after GH9.01, we recommend continuing with a finer polishing compound and then applying protection (sealant, wax, or ceramic coating).
