BOERO EPOYACHT Light Epoxy Filler A+B – 20L is a two-component, lightweight marine epoxy filler designed to smooth irregular surfaces during boat and yacht fairing. Its solvent-free formulation offers good flexibility, impact resistance, and minimal shrinkage, making it suitable for preparing surfaces within a marine coating system. This epoxy fairing compound fills uneven areas and can be sanded to a smooth finish once cured. The 20L set contains 10L of Component A and 10L of Component B, mixed in equal quantities by volume. It is a practical choice for marine buyers looking for a BOERO epoxy product specifically intended for surface filling and fairing.

BOERO EPOYACHT combines straightforward mixing with application by spatula or trowel. The components should be blended thoroughly before application, then worked firmly into the prepared surface. Building the boat filler in layers helps reduce the risk of trapped air while allowing the applicator to develop the required surface profile. Once cured, the material is easy to sand, allowing uneven areas to be levelled before the next stage of the coating process. Its lightweight formulation, flexibility and low shrinkage are useful characteristics when selecting a marine filler for fairing work. The product is also compatible with pump-type mixing machines, supporting both manual and machine-assisted preparation.

This marine epoxy filler is suitable for correctly primed steel, aluminium, composite and wood, with exterior applications including hulls above and below the waterline, superstructures and decks. Surface preparation remains essential: apply it over an approved, cured primer on a clean, dry surface without dust, grease or oil. These requirements make it important to select the filler as part of the intended coating system rather than apply it directly to an unprepared substrate. EPOYACHT can be sealed with EPOMAR finishing filler before subsequent solvent-containing coatings. Its purpose is to correct surface irregularities and develop a smooth profile for further finishing.

The 1:1 mixing ratio by volume provides a clear proportion for preparing each batch: use the same measured volume of Component A and Component B. BOERO lists a theoretical spreading rate of 0.13 m² per litre at 8,000µm, equivalent to 8mm thickness; this figure is tied to the stated thickness and should be considered when estimating material requirements. Thinner 693 is specified for cleaning equipment only, rather than thinning the filler for application. An optional Fast Hardener 603.999 is available to shorten drying and curing times for refit repairs and smaller areas. It is a separate hardener option, so buyers should distinguish the standard A+B set from the FAST version when planning their work.

Key Features:

• BOERO EPOYACHT Light Epoxy Filler A+B – 20L provides a lightweight, two-component filling material for smoothing irregular marine surfaces before further finishing.
• Solvent-free formulation: Offers good flexibility and impact resistance with minimal shrinkage during curing.
• Equal-volume mixing: Mix Component A and Component B at a 1:1 ratio by volume, using measured quantities for each batch.
• Manual application: Apply with a spatula or trowel, working the filler into the surface and building it in layers to reduce air entrapment.
• Pump-machine compatibility: Suitable for preparation with pump-type mixing equipment as well as manual mixing.
• Easy sanding after curing: Allows the applied filler to be shaped and smoothed during the fairing process.
• Optional faster hardener: Fast Hardener 603.999 offers shorter drying and curing times for appropriate refit and small-area work.

Applications / Suitable For:

• BOERO EPOYACHT Light Epoxy Filler A+B – 20L is suitable for boat and yacht fairing where irregular exterior surfaces need smoothing within a compatible marine coating system.
• Hull fairing: For prepared hull surfaces above and below the waterline, following the specified priming and coating requirements.
• Superstructures and decks: For correcting uneven areas before subsequent surface finishing.
• Different construction materials: Suitable over correctly primed steel, aluminium, composite and wooden substrates.
• Marine refit and surface repairs: Useful for fairing work during refurbishment, with an optional FAST hardener for smaller areas requiring shorter drying and curing times.

FAQs:

Q: What is BOERO EPOYACHT Light Epoxy Filler A+B – 20L used for?
A: It is an epoxy fairing compound used to smooth irregular boat and yacht surfaces before further coating. Suitable areas include correctly primed hulls, decks, and superstructures.

Q: Does the 20L size mean 20L for each component?
A: No. The complete set totals 20L: 10L of Component A plus 10L of Component B. Mix equal volumes of the two components.

Q: Can I add Thinner 693 to make the filler easier to spread?
A: Thinner 693 is specified for equipment cleaning only. It is not specified for thinning EPOYACHT during application.

Q: Is a faster-curing option available?
A: Yes. Optional Fast Hardener 603.999 shortens drying and curing times and is intended for refit repairs and smaller areas. Confirm the hardener version when selecting the product.
