Interlux Flattening Agent for 1-Part Finishes — Quart

Take the sheen down on any Interlux 1-part topside finish or varnish without compromising adhesion, durability, or colour. This flattening agent mixes directly into Interlux polyurethane enamels and spar varnishes, letting you dial in exactly the level of gloss you want — from a subtle satin to a full matte — on both interior and exterior surfaces. A single quart goes a long way when used as an additive, making it a cost-effective way to customize the finish on your topsides, cabin sole, brightwork, or interior joinery.

Key Features

  • Specially formulated flattening agent for Interlux 1-part finishes and varnishes
  • Produces gloss, satin, or matte effects depending on mix ratio
  • Compatible with Brightside Polyurethane, Yacht Enamels, Schooner Gold, Compass Clear, Schooner, and Original varnishes
  • Suitable for interior and exterior use
  • Quart size — sufficient for multiple projects when used as an additive

Compatible Applications

  • Topsides and hull sides finished with Interlux Brightside Polyurethane or Yacht Enamel
  • Brightwork and spar varnish projects using Interlux Schooner, Schooner Gold, or Original varnish
  • Interior joinery, cabin soles, and furniture finished with Compass Clear or Goldspar Satin
  • Any surface where a reduced-gloss 1-part finish is desired

Parts Desk Insights

This is the additive to reach for when a customer wants the protection of a Brightside or Schooner finish but finds the standard gloss too reflective for their taste — or when they're trying to match an existing satin or matte surface. Mix ratio controls the final sheen level, so start conservatively and test on a small area. It pairs directly with the Interlux Brightside Off White, Interlux Schooner Varnish, Interlux Schooner Gold Spar Varnish, and Interlux Original Spar Varnish. If the customer needs to thin their finish for spray application, the Interlux Special Thinner 216 is the correct companion product.
