What it is and why choose it
HIGH BUILD EPOXY PRIMER OFF WHITE BASE (D8002) from Awlgrip is a two-component epoxy polyamide surfacer designed for high build and filling above the waterline. When mixed with the appropriate converter (D3002), it provides excellent film build, filling capability and adhesion, creating a smooth, even surface ready for further priming or fairing on properly prepared substrates such as wood and fiberglass/gelcoat.
This off white base offers controlled film thickness, predictable coverage and compatibility with key Awlgrip primers and fairing compounds, making it suitable for professional marine refinishing and industrial applications where a robust, spray-applied epoxy undercoat is required.

Applications and uses
- Primary use: high build epoxy surfacer/undercoat for areas above the waterline where significant filling and levelling are required.
- Typical substrates:
- Existing Awlgrip primers and fairing compounds (optimal use as a surfacer over these systems).
- Properly prepared wood (fine sand with P80–P100 grit).
- Properly prepared fiberglass/gelcoat (sand with P100–P150 grit).
- Best results on wood and fiberglass when first sealed with Awlgrip 545 Primer.
- Professional marine refinishing: surfacing and filling of hulls and superstructures above the waterline prior to further priming or fairing.
- Industrial and OEM finishing: situations requiring an epoxy polyamide surfacer that can be spray-applied to build uniform thickness over large areas.
FAQ
-
What is HIGH BUILD EPOXY PRIMER OFF WHITE BASE used for?
It is an off white epoxy polyamide base used, with converter D3002, as a high build surfacer and filler above the waterline on suitably prepared substrates, especially over existing Awlgrip primers and fairing compounds.
-
Can it be used below the waterline?
No. The technical data clearly states that High Build Epoxy Primer is not to be used below the waterline.
-
How should the product be mixed?
Mix one part base D8002 with one part converter D3002 by volume to a smooth, homogeneous mixture. Allow an induction time of 15 minutes, then reduce 10–20% with the appropriate reducer.
-
Which reducers are compatible?
The recommended reducers are T0006 Standard Reducer for Epoxy Primers and, in North America, T0176 Medium Evaporating VOC Exempt Reducer.
-
What film thickness should I aim for?
Apply 200–250 microns wet per coat to obtain 100–125 microns dry per coat. Two to three coats may be required depending on build needs.
-
How soon can I recoat?
Recoating with itself is possible after about 2 hours. Recoating with other compatible products is typically 12–24 hours, with a maximum of 24 hours without sanding. Sanding is recommended before overcoating with other products.

Section 8 – Personal protective measures
HIGH BUILD EPOXY PRIMER OFF WHITE BASE and its mixed system are intended for professional use and are classified as flammable with serious eye damage and suspected reproductive toxicity. The following personal protection and exposure control measures are indicated in the safety documentation for the base:
- Engineering controls: Use only with adequate ventilation. Employ local exhaust or process enclosures to keep airborne concentrations below occupational exposure limits and below lower explosive limits. Use explosion-proof ventilation and equipment.
- Eye and face protection: Use chemical splash goggles; where risk of higher exposure exists, use a full face shield or full-face respirator providing eye protection.
- Hand protection:
- Wear chemical-resistant, impermeable gloves compliant with EN374 or equivalent.
- For frequent or prolonged contact, the Spanish SDS for High Build Off White Base recommends class 6 gloves (breakthrough time > 480 minutes) such as Viton or nitrile with thickness ≥ 0.38 mm.
- For short contact, class 2 or higher gloves (breakthrough time > 30 minutes) such as nitrile with thickness ≥ 0.12 mm may be used.
- Gloves should be inspected regularly and replaced if any sign of degradation is observed.
- Skin and body protection: Wear suitable protective clothing selected according to task and risks. Where ignition from static electricity is possible, use antistatic protective clothing (overalls, boots and gloves) conforming to relevant standards (for example EN 1149 for antistatic garments).
- Respiratory protection: When ventilation is insufficient or during spraying and sanding, wear a respirator conforming to EN140 with type A/P2 filter or better, as part of a respiratory protection program ensuring correct fit and training.
- Hygiene measures: Avoid contact with eyes, skin and clothing. Do not breathe vapours or spray mist. Wash hands, forearms and face thoroughly after handling and before eating, drinking or smoking. Remove contaminated clothing and protective equipment before entering eating areas and wash thoroughly before reuse. Ensure eyewash stations and safety showers are available close to the work area.
- Environmental exposure controls: Emissions from ventilation and process equipment should comply with environmental protection legislation; where required, use fume scrubbers, filters or engineering modifications to reduce emissions.
