Bristol Finish Water Based Interior Marine Coatings – Application on a Bare Wood

By January 19, 2016 Boat Varnishing Tips

Use a mild wood cleaner to ensure the surface is free of moisture, oils & other contaminants before sanding. Sand wood as required to expose a fresh surface, with final sanding to a 240 grit profile when dry sanded. Ensuring the wood surface is free of dust, blow down with clean, dry filtered air & wash with a Surface Prep solution using the two-cloth method (one wet, one dry). Clean, non-drycleaned rags should be used, or commercial cleaning cloths such as 3M Automotive Wipes, which are lint free.

  1. To a clean, dry surface, apply 2 coats of either Bristol Finish Traditional Amber Urethane or Epifanes Rapidclear Varnish as a sealer coat. Refer to the products ‘technical data sheets’ for bare wood application. Final sanding of either of these products should be a 240 grit profile, when dry sanded. Wash with a Surface Prep solution using the two-cloth method (one wet, one dry), before the next coat application.
  2. To a clean, dry surface, apply a minimum 5-6 coats of Bristol Finish Classic Clear Water Based Interior High Gloss Urethane. More coats may be required, especially for porous & problematic timbers, such as mahogany. Allow a minimum of 1 hour, but no longer than 4 hours between coats. No sanding is required if overcoating occurs within this time period. If this time is exceeded, sand to a 240 grit profile, when dry sanded. Wash with a Surface Prep solution using the two-cloth method (one wet, one dry), before the next coat application.
  3. Before application of the final finishing coat, allow a minimum of 4 hours from the previous coat, then sand the surface to a 240 grit profile, when dry sanded. Wash with a Surface Prep solution using the two-cloth method (one wet, one dry). Use tack cloths prior to painting. Apply 1-2 final coats.
