What is Quick Build Surfacer Converter EU and why choose it
Quick Build Surfacer Converter EU (code OU4200) is a key component of the Awlgrip Quick Build Surfacer system, a three-component, fast-drying polyurethane primer designed to deliver an outstanding Awlgrip finish in both quick and sanded schemes. Used together with the colored Quick Build Surfacer bases and the dedicated activator, this converter helps create a smooth, easily sandable undercoat that can closely match the final topcoat color while reducing the total number of coats required.
Main features
- Essential part of a 3-component system: Works with Quick Build Surfacer bases and Surfacer Activator to form a high-performance polyurethane primer.
- Fast-drying performance: Supports short touch-dry, sandable and hard-dry times to speed up repair and production workflows.
- Color-flexible system: The Quick Build Surfacer range uses six colored bases (white, black, blue, green, red, yellow) to closely match almost any Awlgrip topcoat color.
- Designed for Awlgrip topcoats: Once mixed and applied, the system is suitable for overcoating with Awlcraft SE, Awlcraft 2000, Awlcraft 3000 and Awlgrip Topcoat.
- Application versatility: Optimized for conventional and HVLP spray in both quick and sanded schemes.
- Supports multiple substrates: The mixed Quick Build Surfacer can be applied over properly prepared gelcoat, fiberglass, existing coatings in good condition and suitably primed aluminium.

Applications and use cases
Suitable substrates (mixed Quick Build Surfacer system)
- Gelcoat and fiberglass: After appropriate abrasion (Scotchbrite or 120–180 grade sandpaper).
- Existing finishes in good condition: After sanding with 120–180 grade dry sandpaper and degreasing with Awlprep Wipe Down Solvent.
- Aluminium and anodized aluminium: After abrasion with 180–220 grade paper, degreasing and priming with Wash Primer CF before application of Quick Build Surfacer.
Typical application scenarios
- Quick repair schemes where reduced process steps and fast drying are important while retaining the visual quality of an Awlgrip finish.
- Sanded schemes requiring an easily sandable surfacer that can be fine-finished before high-gloss topcoats.
- Color-critical projects where the undercoat shade needs to be closely aligned with the final Awlgrip topcoat color using the colored bases.
Drying and recoat windows (EU data, mixed system)
- Touch dry: Approx. 10–15 minutes depending on temperature (10–15 minutes at 25°C; 10 minutes at 35°C).
- Sandable: From 1 hour at 35°C to 2 hours at 15°C.
- Hard dry: From 3 hours at 35°C to 8 hours at 15°C.
- Pot life: Approximately 45 minutes at 35°C; 1.5 hours at 25°C; 2 hours at 15°C.
- Overcoating with Awlcraft SE, Awlcraft 2000 or Awlgrip Topcoat (spray): Minimum 60 minutes to 2 hours depending on temperature; maximum interval is extended when the surfacer has been sanded (up to 7 days after sanding in EU data).
Application guidance for the mixed system
- Apply 3 coats by spray with 5–15 minutes flash-off between coats or until the surface becomes matt.
- Quick Build Surfacer can be applied over itself with 2–3 coats and 5–15 minutes flash-off between coats without sanding if recoated within 7 days (EU data).
- Before applying any topcoat, sand Quick Build Surfacer with P400 and clean with Surface Cleaner T0340 (EU) using the two-cloth wipe-down method.
- Before metallic topcoats, sand with no finer than P400 grade paper.
- Ensure the surface is clean and free of dust before overcoating.
- Do not apply when the surface is less than 3°C (5°F) above the dew point or warmer than 41°C (105°F). Ambient temperature should be between 10°C (50°F) and 41°C (105°F).
FAQ
-
Is Quick Build Surfacer Converter EU a standalone product?
No. It is a converter component that must be used with Quick Build Surfacer bases and the dedicated Surfacer Activator to form the complete three-component primer system.
-
What is the correct mixing ratio for the EU Quick Build Surfacer system?
The recommended ratio is 3 : 1 : 0.4 by volume (Base : Quick Build Surfacer Converter : Surfacer Activator).
-
Do I need to thin the mixed Quick Build Surfacer?
No reduction is required. However, 5–10% Awlgrip reducers (T0001, T0002, T0003, T0005) may be added if needed to ease the application experience.
-
Which topcoats can be applied over the Quick Build Surfacer system?
After correct preparation and sanding, the system can be overcoated with Awlcraft SE, Awlcraft 2000, Awlcraft 3000 and Awlgrip Topcoat, following the recoat times given in the data sheet.
-
On which substrates can the mixed Quick Build Surfacer be used?
It can be applied directly to properly prepared gelcoat, fiberglass and existing coatings in good condition, and over aluminium or anodized aluminium that has been abraded and primed with Wash Primer CF.
-
What is the recommended film thickness?
For the full system, a total dry film thickness of 120–140 µm (4.7–5.5 mils) is recommended, typically achieved with 3 spray coats.
-
How long can I wait before overcoating Quick Build Surfacer with a topcoat?
According to the EU data, once sanded, Quick Build Surfacer can be overcoated with topcoat for up to 7 days at 15°C, 25°C and 35°C, provided the surface remains clean and properly prepared.
-
What is the pot life of the mixed Quick Build Surfacer?
Pot life ranges from approximately 45 minutes at 35°C to 2 hours at 15°C, depending on temperature.
