Title: lacquer
Post by: pipercub1772 on January 21, 2019, 09:37:38 PM
Hi i am planking the deck of my steam launch in mahogany and lime and i always use several coats of varnish ,problem is the lime always yellows  , so can you use lacquer directly on bare timber and would the lime still yellow any comments appreciated regards Allan.

Hi Alan


I would try Halfords clear automotive laquer in aerosol form.It will take a while to build the finish up but anything polyurethane intended for wood will yellow over time.


Regards


Nigel

Try Halfords bodyshop professional spray, it's a little more expensive at 10 a can but it sure is worth it...

Most exterior grade varnishes have UV filters in them to protect the surface from sunlight. These give a yellow tint to the varnish even before you apply it.

You might like to have a look at specialist craft varnishes such as Duraclear which are non yellowing, highly transparent and can be used inside and outside. They are quick dry types.

They are made in America, there is a link to Duraclear Varnishes on the manufacturer website:

but they are widely available in the UK from craft shops or from Amazon:

Also bear in mind that recently cut wood can change colour as it ages and is exposed to light, for example the rich colour of teak fades to a silvery grey if left untreated.
