Drying and pot life
- Sandable time:
- 15°C (59°F): 1.5 hours.
- 25°C (77°F): 60 minutes.
- 35°C (95°F): 35 minutes.
- Pot life:
- 15°C (59°F): 25 minutes.
- 25°C (77°F): 10 minutes.
- 35°C (95°F): 5 minutes.
Overcoating and recoatability
- Overcoating window: Recoat within 72 hours of sanding at 25°C (77°F); after this time, light sanding is recommended.
- Compatible overcoats (over sanded Aerowave 2501): 545 Epoxy Primer, Aerowave 2501, Awlcraft 2000, Awlcraft SE, Awlgrip HDT Single Stage, Awlgrip Topcoat (Spray), Quick Build Sealer, Quick Build Surfacer.
- Minimum overcoating times (by temperature):
- 15°C (59°F): 1.5 hours (minimum) – extended maximum.
- 25°C (77°F): 60 minutes (minimum) – extended maximum.
- 35°C (95°F): 35 minutes (minimum) – extended maximum.
- Best practice: Apply topcoats over a suitable Awlgrip primer. Use topcoats directly over Aerowave 2501 only for very small repairs (pinholes, very small scratches) to reduce the risk of filler grain showing through.
Applications and use cases
Recommended substrates and surface preparation
- GRP / Gelcoat:
- Remove all waxes, mould release agents, dirt and grease.
- Sand with 120–180 grade dry sandpaper.
- Fiberglass and existing coatings in good condition:
- Aerowave 2501 may be applied directly to these surfaces after proper cleaning and sanding (120–180 grade dry sandpaper for existing finishes).
- Steel, bare aluminium and anodized aluminium:
- Prime first with a suitable Awlgrip primer before applying Aerowave 2501.
- Freshly applied Awlgrip primer:
- No sanding required if overcoated within the recommended recoat intervals of the primer.
Suggested application workflow
- Prepare the surface as described for the relevant substrate.
- Mix Aerowave 2501 Base and Curing Solution at 1:1 (by volume or weight) until a uniform beige colour with no streaks or lumps is obtained.
- Apply with a spatula, putty knife or trowel to an area that can be worked within the available pot life (pot life decreases as temperature increases).
- Screed tightly across the surface to fill pinholes, scratches or small defects.
- Allow the first coat to dry, then apply a second tight screed if necessary to remove remaining minor defects.
- Once cured, sand Aerowave 2501 with P240–P400 abrasive, depending on the intended overcoating system.
- Clean with Surface Cleaner T0170 (US) or T0340 (EU) using the two-cloth wipe-down method.
- Overcoat with the selected Awlgrip primer or topcoat within the recommended recoat window.
Environmental and application conditions
- Do not apply to surfaces less than 3°C (5°F) above the dew point.
- Do not apply to surfaces warmer than 41°C (105°F).
- Ambient temperature should be between 10°C (50°F) and 41°C (105°F).
