Varnishing Wood

Particular tips when varnishing wood

  • Consider the construction of the substrate and remember that it is not advisable to put a two pack system on to carvel or clinker built wooden hulls as they require the benefits of the greater flexibility of a single pack system.
  • Sand wood at 45o to the grain with 80-120 grade abrasive paper to provide a key for the paint system.
  • Clean wood by wiping Thinner 823 along the grain with a cloth and allow to dry. Oily woods such as teak and iroko should be degreased by wiping Degreaser along the grain, which will remove some of the natural oil content on the surface and ensure a greater bond with the first coat.

For advice on repainting wood see the section on repainting. Marine varnish contains higher UV inhibitors and goes well with marine paints.
