The Converter (hardener) component of the Interlux YAV135 two-part sprayable fairing system. Designed to be mixed with the Interlux Sprayable Fairing Compound Base (1 L) to create a high-build, sprayable epoxy filler ideal for fairing and smoothing boat hulls prior to painting.
Key Features
- Part of a two-component sprayable epoxy fairing system — must be used with the matching Base
- Suitable for use on GRP (fiberglass), metals, and rigid wood constructions
- Non-shrinking formulation for a stable, long-lasting fill
- Extremely water resistant — suitable for osmosis damage repairs and below-waterline applications
- Fills up to 3/4" without sagging when applied correctly
- High-build formula that sands smooth for a fair, paint-ready surface
- Simple 1:1 mixing ratio by volume with the Base component
Best Use Cases
- Fairing and smoothing fiberglass hulls before applying antifouling or topside paint
- Repairing osmosis blistering and moisture damage on GRP hulls
- Filling surface imperfections, gouges, and low spots on metal or wood hulls
- High-build primer fairing on new builds or full repaint projects
Parts Desk Insights
This is the Converter (hardener) half of the YAV135 sprayable fairing kit — it does nothing on its own and must be paired with the Interlux Sprayable Fairing Compound Base (1 L) at a 1:1 ratio. Best suited for boaters doing a full hull fairing job who want a sprayable (rather than hand-applied) filler for a faster, more even build. For surface prep and cleanup, Interlux Special Thinner 216 is the recommended solvent for this system. Not a standalone filler — if you need a single-component hand-applied repair product, see our Emergency Repair Epoxy Putty Stick instead.
