Varnish over Cetol filter 7?

[JSYmartini]

I'm in the process of re varnishing my wheelhouse door. I found a tin of cetol wood stain in the paint store and I think that is what has been used for all of my interior wood.

I've taken the door back to bare wood and obviously it's much lighter than the rest of the wood so is it normal to stain then varnish over the top?

And can this be done with Cetol filter 7?

Cetol does not need varnish. Just apply according to the instructions on the tin. It is a porous coating so varnish on the top will prevent it from doing its job. it does not actually stain the wood, the colour (if any) comes from a pigment in the mix.

I'm looking for a smooth gloss finish though, I want to varnish it!

I only wanted to apply the teak coloured Cetol as I'm assuming it'll give the correct colour match as the rest of my interior.

Read and you will know as much as anyone.

It appears to be a microporous, water-repellent, UV resistant, satin finish for exterior use. It may be an alternative low maintenance coating similar to the popular, but now obsolete, Cetol Marine or the new International Woodskin.

There is no information on overcoating it with gloss varnish. For exterior use that would defeat most of the benefits.

It may have been used on your interior woodwork and then overcoated. Impossible to know!

OK if you want traditional gloss varnish then use it, but don't mix it with a porous woodstain product. Stain your wood to the colour you want with a woodstain intended to colour the wood. I use Coloron wood dye which you can get in a range of tints.

Not sure why you would want to use conventional varnish on something like a wheelhouse door, unless you like lots of work and need an excuse to get away from the pub. Cetol is a much superior product for the job. Easy to apply, does not flake or crack, easy to touch up and will last over 5 years.

Having said that Cetol is not ideal for interior as its benefits do not show on interior work - but no reason to change it if it is already done.
