What is Epifanes Epoxy Filler 1500 and why choose it
Epifanes Epoxy Filler 1500 is a high‑build, two‑component epoxy filler designed for durable fairing and repair work above and below the waterline. Based on phenol‑free epoxy resins, it is completely shrink‑free, water‑resistant and highly mechanically resistant, with excellent impact strength and sandability. The filler can be applied in a single layer up to 15 mm (1.5 cm), making it suitable for both minor imperfections and deeper repairs on stable substrates.
Used in combination with appropriate Epifanes epoxy or polyurethane primers, Epoxy Filler 1500 offers a robust base for long‑term protective and decorative coating systems on wood, steel, aluminium and polyester (FRP).
Main features
- Two‑component epoxy system: base (Component A) and hardener (Component B) for strong, chemical‑curing performance.
- Shrink‑free curing: 100 % shrink‑free during drying and after full cure for dimensionally stable repairs.
- High mechanical strength: highly resistant to impact and abrasion; suitable for demanding marine environments.
- Water‑resistant and immersion‑resistant: suitable for use under and above the waterline when overcoated with the correct primers and systems.
- High build in one pass: apply up to 15 mm layer thickness without sagging.
- Good sandability: sands well after curing, allowing smooth fairing of hulls and superstructures.
- Low odour: more comfortable to use than many conventional fillers.
- Usable in one‑ and two‑component paint systems: commonly used within two‑component systems, but also increasingly incorporated under selected one‑component primers.

- Theoretical coverage: about 1000 ml per 11 ft² at 0.5 mm film thickness (approx. 1.1 m² per litre at 0.5 mm).
Drying and overcoating times
Approximate times after application, depending on temperature:
- At 12 °C / 54 °F:

- Recoatable: 36 h
- Chemically cured: 72 h
- At 20 °C / 68 °F:

Surface preparation
- All substrates must be dry, clean and free from oil, grease, wax, dust and other contaminants.
- FRP / polyester mouldings:
- Structures must be at least 14 days old and free from chemicals.
- Degrease thoroughly with Epifanes Fiberglass/Polyester Degreaser to remove waxy residues.
- Remove the paraffin layer with steel wool or Scotch‑Brite to obtain a clean, slightly rough surface.
- Steel and aluminium: preferably apply the filler between primer coats of the paint system rather than directly on bare metal.
- Small scratches and holes: clean, degrease and sand with a coarse grit, then fill directly.
- Larger areas or deeper defects: first prime the substrate with Epifanes Epoxy Primer or Epoxy HB Coat, allow to dry and sand with P120–150 before applying filler.
Sanding
- Before sanding, remove any amine blush from cured epoxy surfaces by wiping with:
- water with vinegar, or
- water with ammonia, or
- Epifanes Cleaning Thinner / Cleaning Solvent, or
- Epifanes Fiberglass/Polyester Degreaser, or
- acetone.
- After cleaning, sand filled areas dry with P100–120 (or P120 dry as indicated).
- When applying multiple coats of filler, each coat must be cleaned and sanded with P80–100 before the next application; sand the final coat with P100–120.
Applications and typical uses
- Marine hull and superstructure fairing: smoothing and fairing of GRP, wood, steel and aluminium surfaces above and below the waterline in combination with suitable primers.
- Gelcoat repair: filling small holes and defects in gelcoat below the waterline prior to overcoating with Epifanes epoxy primers and finishing systems.
- High‑build filling: building up to 15 mm thickness in a single pass for deeper dents, joints or construction irregularities.
- Maintenance and refit: restoration of aged or damaged epoxy and polyester laminates after correct surface preparation.
- Industrial and structural components with minimal movement: filling and levelling on stable substrates that do not undergo large dimensional changes.
FAQ
-
On which substrates can Epifanes Epoxy Filler 1500 be used?
According to the product information, it can be used on wood, steel, aluminium and polyester (FRP) structures with minimal movement, both under and above the waterline, when combined with suitable primers.
-
What is the maximum thickness I can apply in one coat?
The filler can be applied up to a maximum of 15 mm (1.5 cm) in a single application without sagging.
-
How long should I wait before sanding?
At 20 °C / 68 °F, the filler is typically sandable after about 24 hours. At 12 °C this extends to around 36 hours, and at 28 °C it can be sandable after approximately 18 hours.
-
Which primers can I apply over the cured filler?
Suitable primers include Epifanes Epoxy Primer, Epifanes Epoxy HB Coat, Epifanes Poly‑urethane Primer and Epifanes Multi Marine Primer, depending on whether the area is above or below the waterline and whether a one‑ or two‑component system is used.
-
Can I apply the filler directly on bare steel or aluminium?
The product information advises not to apply the filler directly on bare steel or aluminium where possible, but to place it between the (two‑component) primer coats of the coating system.
-
How do I treat amine blush before sanding?
If curing occurs at lower temperatures and high humidity, an amine blush (sticky film) can form. This must be removed before sanding by wiping with water plus vinegar, water plus ammonia, Epifanes Cleaning Thinner, Epifanes Fiberglass/Polyester Degreaser or acetone, then allowing to dry.
-
Is the product suitable for continuous immersion?
The Dutch product sheet states that the filler is water‑resistant and resistant to immersion in water when used in combination with appropriate primers and paint systems.
-
What is the theoretical coverage?
A mixed volume of 1000 ml covers approximately 11 ft² at 0.5 mm thickness (about 1.1 m² per litre at 0.5 mm).
-
Can I use Epoxy Filler 1500 in a one‑component paint system?
Yes. Although mainly used within two‑component paint systems, the Dutch datasheet indicates that it is increasingly also processed in one‑component systems, when combined with suitable primers such as Epifanes Multi Marine Primer.
-
What should I do with leftover mixed filler?
Mixed filler has a limited pot life. Any remaining material that has started to react must be allowed to cure fully and disposed of according to local regulations. Do not pour uncured product into drains or the environment.
