What is Awlfair Surfacing Filler Converter and why choose it?
Awlfair Surfacing Filler Converter (D3200 / OD3200) is the curing component of the Awlfair Surfacing Filler high-end, two-component epoxy finishing system from Awlgrip. Used in combination with the D6200 base, it creates a non-shrinking, solvent-resistant finishing filler designed to eliminate sand scratches, pinholes and minor surface imperfections over Awlfair LW Fairing Compound before sealing, high-build priming or topcoat systems.
This converter is formulated to deliver a very smooth, high-quality surface with excellent solvent resistance and an optimized health and safety profile when used as directed.

FAQ
-
What is the role of AWLFAIR SURFACING FILLER CONVERTER in the system?
It is the curing agent (converter) that reacts with the Awlfair Surfacing Filler base D6200 to form a hard, solvent-resistant epoxy finishing filler.
-
What is the correct mix ratio between base and converter?
The recommended mix ratio is 2:1 by volume (base D6200 : converter D3200), or approximately 2.37:1 by weight.
-
Can I thin or reduce the mixed filler?
No. Do not add reducers, solvents or thinners of any kind to Awlfair Surfacing Filler. The product must be used without dilution.
-
How thick can I apply the mixed filler?
The recommended dry film thickness per coat is 100 µm (3.9 mil), with a maximum of 100 µm per coat and a maximum total thickness of 500 µm (20 mils) in several tight screeded layers.
-
When can I sand Awlfair Surfacing Filler?
Awlfair Surfacing Filler can typically be sanded after 24 hours at 15 °C, 6 hours at 25 °C, or 2 hours at 35 °C. Use P100–P120 grit paper.
-
Which primers can I apply over the sanded filler?
Once sanded, it can be recoated with Awlfair Surfacing Filler itself, High Build epoxy primers, Hullgard and Hullgard Extra Epoxy Primers, Epoxy Sprayable Fairing Compound / Ultra Build, 545 Epoxy Primer and Awlquik, following the specified overcoating intervals.
-
Are there temperature limitations for use?
Yes. The system should not be used below 13 °C (55 °F) or above 40 °C (104 °F), as correct application and cure may be difficult outside this range.
-
Can I wipe cured filler with solvent before overcoating?
No. Do not wipe down cured Awlfair Surfacing Filler with thinners or solvents. Surface preparation should be by sanding and, if required, detergent and fresh water wash.
-
What should I do if a surface by-product appears during cure?
Low temperature combined with high humidity can produce a surface by-product (amine exudate) that must be removed either by detergent washing followed by fresh water rinse, or by sanding.

Section 8 – Individual protection measures
The converter contains corrosive and sensitising components. Appropriate personal protective equipment (PPE) and exposure controls are essential.
Exposure controls
- Engineering controls: If operations generate dust, fumes, gas, vapour or mist, use process enclosures, local exhaust ventilation or other engineering controls to keep airborne exposures below applicable limits.
- Workplace hygiene: Wash hands, forearms and face thoroughly after handling chemicals, before eating, smoking and at the end of the work period. Contaminated work clothing should not be taken off-site and must be washed before reuse. Ensure eyewash stations and safety showers are close to workstations.
Personal protective equipment
- Hand protection:
- Use chemical-resistant gloves compliant with EN 374.
- Recommended materials: Viton or nitrile gloves.
- For prolonged or frequently repeated contact: gloves with protection class 6 (breakthrough time > 480 minutes according to EN 374).
- For short contact: gloves with protection class 2 or higher (breakthrough time > 30 minutes according to EN 374).
- Final glove choice must consider all workplace factors (other chemicals handled, cut/puncture risk, dexterity, thermal protection, etc.).
- Eye and face protection:
- Use safety eyewear that meets approved standards when risk assessment indicates exposure to splashes, mists, gases or dust.
- Recommended: chemical splash goggles and/or face shield. Where there is inhalation risk, a full-face respirator may be used instead.
- Skin and body protection:
- Wear appropriate protective clothing selected based on the specific task and risks, and approved by a specialist before handling the product.
- Select suitable footwear and any additional skin protection as required by the application.
- Barrier creams may help protect exposed skin areas but must not be applied after exposure has occurred.
- Respiratory protection:
- Use a properly fitted respirator with particle filter meeting approved standards when risk assessment indicates it is necessary.
- Respirator selection must be based on actual or expected exposure levels, product hazards and the reliability of the chosen respirator.
Environmental exposure controls
- Check emissions from ventilation or process equipment to ensure compliance with environmental protection legislation.
- Where necessary, use scrubbers, filters or modify process equipment to reduce emissions.
