Applications and use cases
Awlfair Surfacing Filler is intended for professional and industrial use as part of a multi-coat epoxy fairing and priming system where Awlfair LW Fairing Compound has been applied beforehand.
Typical applications
- Fine surfacing over Awlfair LW – removal of sand scratches, pinholes and small surface irregularities after fairing.
- Preparation for high-build or finish primers – creating a uniform, smooth, solvent-resistant base before sealing, high-build or finishing primers.
- Interior and exterior use – suitable for two-component filler applications in both environments when used within the specified temperature range.
Application guidelines (summary)
- Sand Awlfair LW Fairing Compound before application of Awlfair Surfacing Filler.
- Mix base and converter thoroughly to a uniform, even colour with no streaks.
- Apply by trowel, spatula, batten or putty knife over an area that can be worked within the product’s pot life at the prevailing temperature.
- Screed tightly across the surface to level it. After drying, apply a second tight screed at 90° to the first to eliminate remaining defects. A third application can be used if required to achieve the final smooth finish.
- Apply only within the temperature range of approx. 13°C to 40°C. Application and cure may be more difficult outside this range.
- Avoid conditions of low temperature combined with high humidity, as these can generate a surface by-product that must be removed by detergent washing followed by fresh water rinse or by sanding.

Section 8 – Individual protection measures
Awlfair Surfacing Filler is intended for professional and industrial use. A risk assessment should be carried out to determine the exact level of personal protective equipment (PPE) required. The following measures are highlighted in the safety data information:
General hygiene measures
- Wash hands, forearms and face thoroughly after handling and before eating, drinking, smoking or using the lavatory.
- Remove contaminated clothing and protective equipment before entering eating areas.
- Contaminated work clothing should not leave the workplace and must be washed before reuse.
- Ensure eyewash stations and safety showers are available close to the work area.
Eye and face protection
- Use safety eyewear complying with an approved standard when there is a risk of splashes, mists, gases or dusts.
- Recommended: chemical splash goggles and/or face shield.
- If inhalation hazards exist, a full-face respirator may be required instead of goggles.
Hand protection
- Wear chemical-resistant, impervious gloves conforming to an approved standard whenever handling the product.
- For prolonged or frequently repeated contact, gloves with protection class 6 (breakthrough time > 480 minutes according to EN374) are recommended. Suggested materials: Viton or nitrile with thickness ≥ 0.38 mm.
- For brief contact, gloves with protection class ≥ 2 (breakthrough time > 30 minutes according to EN374) are recommended. Suggested material: nitrile with thickness ≥ 0.12 mm.
- Replace gloves regularly and whenever damage or deterioration is observed.
Skin and body protection
- Wear suitable protective clothing selected according to the task and the associated risks, and approved by a specialist.
- Use appropriate protective footwear and any additional skin protection measures required by the risk assessment.
Respiratory protection
- When ventilation is insufficient or when exposure levels may exceed applicable limits, wear respiratory protection as part of a respiratory protection program.
- Recommended: respirator conforming to EN140 fitted with type A/P2 filter or better.
- Dry sanding, flame cutting or welding of the dry film can generate hazardous dust and fumes – wet sanding/flatting is preferred. If exposure cannot be controlled by local exhaust ventilation, suitable respiratory protection must be used.
Environmental exposure control
- Emissions from ventilation systems or process equipment should be checked to ensure compliance with environmental legislation.
- Where necessary, use fume scrubbers, filters or engineering modifications to reduce emissions.
