What it is and why choose it
High Build Epoxy Primer Off White Converter by Awlgrip is a high-build, two-component epoxy polyamide surfacer designed for applications where substantial filling and surface levelling are required. Used in combination with the off white base D8002 and converter D3002, it creates a robust epoxy undercoat that can be sanded and overcoated with compatible Awlgrip primers and fairing compounds. It is intended for use above the waterline only.
This system delivers high film build per coat, excellent filling power and controlled recoat times, making it suitable for professional applications on properly prepared wood, gelcoat and fiberglass substrates, particularly as a surfacer over other Awlgrip primers and fairing products.
Main features
- High-build epoxy surfacer: Two-component epoxy polyamide designed to provide 100–125 microns dry film per coat, with 2–3 coats typically required.
- For filling and levelling: Formulated for use where significant build and filling are required prior to subsequent priming, fairing or topcoating.
- Above-waterline use: Specifically indicated as not for use below the waterline.
- Compatible system: Can be overcoated with Awlgrip 545 Epoxy Primer, ULTRA BUILD, Sprayable Fairing Compound, AWL®FAIR L.W. and AWL®QUIK.
- Controlled recoat windows: Recoatable with itself after 2 hours and with other compatible products after 12–24 hours, with a maximum of 24 hours without sanding.
- Professional spray application: Designed for conventional or airless spray with pressure-feed equipment; roll-and-tip application is not recommended.
- VOC information available: VOC values are specified for both the off white base D8002 and converter D3002, including VOC-exempt classification for D3002 in North America when used with reducer T0176.

Applications and use cases
- High-build surfacer over Awlgrip systems: Optimised for use as a surfacer over other Awlgrip primers and fairing compounds, providing a smooth, high-build base for subsequent coatings.
- Wood substrates: May be applied directly to properly prepared wood, finely sanded with P80–P100 grit paper, though best results are obtained when the surface is first sealed with 545 Primer.
- Gelcoat and fiberglass: Suitable for properly prepared gelcoat and fiberglass sanded with 100–150 grit (P100–P150) paper, ideally sealed with 545 Primer beforehand.
- Professional marine and industrial finishing: Intended for professional application where controlled film build, filling and compatibility with Awlgrip fairing and priming systems are required.
Surface preparation
- Best practice: Use as a surfacer over other Awlgrip primers and fairing compounds.
- Direct-to-substrate (where permitted):
- Gelcoat/fiberglass: Sand with 100–150 grit paper.
- Wood: Smooth sand with 80–100 grit paper.
- Sealing for optimum results: Best results are obtained when wood and fiberglass substrates are first sealed with 545 Primer.

Exposure controls and general hygiene
- Use only with adequate ventilation. Where necessary, use local exhaust or explosion-proof ventilation systems to keep airborne concentrations below applicable exposure limits and to keep vapour levels below the lower explosion limit.
- Wash hands, forearms and face thoroughly after handling chemicals, before eating, drinking or smoking, and at the end of the work shift.
- Remove contaminated clothing and protective equipment before entering eating areas and wash contaminated garments before reuse.
- Ensure eye-wash stations and safety showers are close to the workstation.
Individual protection equipment
- Respiratory protection: Use an appropriately fitted air-purifying or air-supplied respirator conforming to approved standards if risk assessment indicates this is necessary. Selection should be based on expected exposure levels, product hazards and the reliability of the chosen respirator.
- Hand protection: Wear chemical-resistant gloves complying with EN 374 (protective gloves against chemicals and micro-organisms). Recommended glove materials include Viton or nitrile.
- For prolonged or frequently repeated contact, gloves with protection class 6 (breakthrough time > 480 minutes according to EN 374) are recommended.
- For brief contact, gloves with protection class 2 or higher (breakthrough time > 30 minutes according to EN 374) are recommended.
- Eye/face protection: Use chemical splash goggles or equivalent eye protection meeting approved standards whenever there is a risk of liquid splashes, mists, gases or dusts.
- Skin and body protection: Select protective clothing based on the specific task and risks, approved by a specialist. Where there is a risk of ignition due to electrostatic charges, wear antistatic protective clothing, including coveralls, boots and gloves with antistatic properties, in line with EN 1149 requirements.
- Additional skin protection: Select appropriate footwear and any additional skin protection required by the task and associated risks.
Environmental exposure control
- Check emissions from ventilation or process equipment to ensure compliance with environmental protection legislation. Where necessary, use fume scrubbers, filters or modify the process equipment to reduce emissions.
