Which Varnish to Finish?

[Paul Jackson 1Participant @pauljackson1]

I have recently returned to model boats. Then I read about applying a matt varnish to finish off a hull just what can I use? Does it have to be brush applied or can I use an aerosol? If aerosol is possible could you please name a make? Thanks.

Paul,

It rather depends on what finish you are wanting to apply the varnish to.

Aerosols can be tricky as the solvent can react with the existing surface. An effective solution is often to use interior polyurethane varnish eiher sprayed with an airbrush or simply brushed on.

Don’t get the quick drying type (acrylic) of brush varnish as it isn’t really suitable for this sort of application. Ronseal polurethane varnish isn’t quite so easy to get hold of as it used to be but Wilkinsons in the UK do their own brand which works well.

 

You an use the exterior version but it contains UV filters which give it a slight yellow tinge so it isn’t very good on lighter colours.

Hi Paul,

 

In response to your PM I have not sprayed it but many have.

 

In his article on painting in the recent Special issue of Model Boats Paul Freshney says that he thins it 1 part varnish to 4 parts thinners and applys a number of very thin coats to achieve a perfect finish.
