Varnishing over teak oil

[Magic Star]

HI, guys, did anyone varnished the teak, which previously was treated with teak oil? Any issues or any advice how to prepare the wood?
Could I just, say, just leave it over winter, wash it a couple of times with jet pressure and degrease with white spirit?
Thanks for tips

I know Danish Oil is used as a wood primer. I think Teak Oil is similar.

From Rustin's data sheet

Rustins Polyurethane Varnish may be applied over Rustins Teak Oil at any time. The surface must be clean before varnishing.

Personally I won't let a pressure water anywhere near teak. If using ordinary yacht varnish (ie not two-pack polyurethane) I'd clean and degrease with white spirit, very lightly sand and clean again and start varnishing, first coat well thinned with more white spirit. That first very thin coat may take a couple of days to go hard, subsequent coats will be normal drying time.

Agree it takes out all the grain. As an aside, Teak oil sold in chandlers contains Castor oil, which is not mentioned on the pack, which goes black with UV damage, get hold of pure teak oil if intending to oil the teak.

Indeed. 'Teak oil' is strictly a marketing term: it is oil-for-teak, not the oil of teak. As such it will contain an assortment of oils and sometimes waxes. Linseed is perhaps the most common; tung oil is held by some to be the most beneficial. Teak's natural oil is better than all of them, and comes free with every plank.
