Boat Varnishing Techniques & Tips

Many boat owners' favourite way to show off the natural beauty of their boat is with boat varnish. We believe that for wooden boats it is best to stick to the traditional type of oil based boat varnish, or the natural sheen and ease of maintenance of an oiled finish. However, maintaining that glossy varnish finish doesn't have to be a battle.

Surface Preparation

Preparation is always key, even if you are just touching up the paintwork on your boat, the surface should always be sanded so that the new varnish will adhere to it. Varnish should always be sanded with a fine grit, 150 or less, a course paper will leave scratches which will be impossible to hide. The smoother the surface of the bare wood the better will be the final finish.

Once the sanding is complete it is vital that you clean off all traces of dust, then finish off by wiping the surface with a 'tack rag', a lint free cloth damped with white spirit or denatured alcohol. There may be occasions when you wish to remove unsightly wood stains from the surface before re-varnishing, this can be done with a bleaching solution such as oxalic acid.


The reason we advise for priming the wood, whether for painting or varnishing is to create a good bond between the wood and the paint/varnish. When brushing out the boat varnish, finish off by brushing with the grain, most of this first coat should soak into the wood leaving very little gloss on the surface.

The first sealer coat of boat varnish to penetrate deeply it needs to be thinned fifty/fifty with mineral spirits, this first coat will raise a 'nap' on the surface which will need to be sanded flat before any subsequent coats, the second coat need only be thinned by about twenty-five percent. Sand again and touch up any bare spots then sand again before going on to applying un-thinned coats of boat varnish. Two coats is the minimum you will need.

Top Coats

When you are satisfied with the base coats allow them at least 24 hours to dry.

Then after a final sanding and clean up you can begin coating with un-thinned boat varnish. Pour enough varnish for one coat into a small container then reseal the can to keep the remaining varnish from being contaminated. When brushing out the varnish, finish off by brushing with the grain.

How many coats is up to you but the very minimum is three preferably five or more. Then, after all that careful work you need to maintain the finish and UV protection by giving it a coat or two every few months or so.
