Bottomkote NT is a hybrid: it has the wear resistance of a hard coating with a controlled polishing action, so it sheds light growth and smooths out with use instead of building up season after season. That combination is why it works on both power and sail, where a straight ablative would wear through and a straight hard paint would need stripping.

  • Substrates: fiberglass, wood, and properly primed steel or lead underwater surfaces. Not for aluminum hulls or outdrives.
  • Coats: at least two full coats, with an extra coat on bare wood and on high-wear areas like leading edges and the waterline.
  • Fast dry. Under normal conditions you can apply multiple coats and launch the same day, which matters when the yard has you on a schedule.
  • Over existing bottom paint: check the Interlux antifouling compatibility chart first, then clean and sand as required.
  • Thinning: only if necessary, with the correct Interlux thinner, and not beyond the label recommendation.

Four colors: red, green, blue and black, in quart and gallon.

  • Substrates: Fiberglass, wood, and properly primed steel/lead underwater surfaces
  • Existing bottom paint: Check the Interlux antifouling compatibility chart to confirm suitability, then clean and sand as required
  • Coats: Apply at least two full coats; use an extra coat on bare wood or high-wear areas such as leading edges and the waterline
  • Thinning: Thin only if necessary, using the appropriate Interlux thinner, and do note exceed label recommendations
  • Hybrid hard/ablative technology - Combines hard-coat durability with a controlled polishing action to help prevent premature wear-through while still shedding light growth.
  • Smooth, efficient finish - As the surface slowly smooths with use, it helps reduce drag for better speed and fuel efficiency.
  • Fast-dry formula - Under normal conditions you can apply multiple coats and launch the same day, making it ideal for tight haul-out schedules.
  • Versatile application - Suitable for fiberglass, wood, and properly primed steel or lead underwater areas (not for aluminum hulls or outdrives).
  • Universal use - Works for most power and sailboats in fresh, salt, and brackish waters, making it a flexible choice for mixed cruising areas.
  • Strip loose, flaking, or heavily built-up antifouling using appropriate methods (chemical stripper for fiberglass/wood or sandblasting for steel).
  • Once the substrate is clean and sound, follow the bare fiberglass, bare wood, or primed metal system as directed.
  • Remove mold release wax and contaminants with the recommended Interlux fiberglass prep products.
  • Fair any imperfections as needed.
  • Follow either the no-sand or sanding system detailed in the Interlux datasheet, typically involving a suitable primer or barrier coat followed by multiple coats of Bottomkote NT.
  • Sand the surface smooth and clean off dust.
  • Apply an initial thinned coat of Bottomkote NT to help penetration, then follow with additional full coats as directed on the label.
