   Danish Oil is simply a thinned oil-varnish blend, the proportions depend upon manufacturer. So, yes, you can apply an oil-based varnish over the top.

   You can also apply a coat of water based poly over a Danish oil finish provided;

   a. the Danish oil has been allowed ample drying time (72-96 hours depending on temperature and humidity).

   b. a barrier coat of shellac is applied before the poly.

   Oh, yeah, you sure can - but the Danish Oil definitely needs time to dry. Let it go about a week - if you can still smell it, wait a while longer.Tom Iovino

   by the way, what can I use to dilute the  Polyurathane so it dry time is a little longer.  (I tend to spray instead of brushing).

   thanks.

   The less thinner you apply to the poly, the longer it takes to dry. You'll have to strike that balance....Tom Iovino

   Hello Tampa,

   You meant the more thinner, the longer time to dry?

   What do I use to thinner the poly?

   thanks.

   Actually - more thinner equals a faster drying time. Thinners are more volatile than the oils and resins - they evaporate faster.Thinner for poly is mineral spirits....Tom Iovino

   If you plan to spray, don't you want a shorter dry time rather than longer.  Polyurethane varnish isn't generally considered a good candidate because of the slow dry time that leaves the overspray a sticky mess.  Naptha flashes off faster than mineral spirits, affecting the time for flow out, but the basic cure of the varnish will not be affected, except that thinner coats cure faster than thicker ones.

   Thank you.  I thought thinner will allow them time to uniform even a little before they get dry.  Or should I stick with the brush then, but the stand and canopy ( which I made for the fish tank)  is big that took me 3-4 hours...

   Vincent,

   Just a thought; since you are contemplating putting a sprayed top coat, you may want to try a water based conversion varnish like Targets' EM8000 cv. I recently switched to this for safety and environmental reasons and I have been delighted with results, it sprays beautifully. The company has a wonderful web site and the CEO is almost always the person who answers technical questions. I have no affiliation with Target other than loving their products.

   I have done this on gunstocks with good results.  I let it dry for several day but I do not know if it was necessary.  I finished a M21 Winchester in this method trying to duplicate the factory finish.  It looks great twenty years later and it still shooting ducks.

   I have no way to test it but I think it a good way to seal end grain.  End grain is where you can have problems with moisture absorption in gunstocks.  Regardless of what I use to finish the stock with, the butt always gets all the Watco it can soak up followed by polyurethane.

   Good Luck

   Thinning product labeled "Paint Thinner" will contain chemicals in addition to pure mineral spirits. These chemicals slow down the evaporation time somewhat. Look for Paint Thinner that says something like contains "Conditioners", "Improves Flowout", etc.In order of evaporation, naphtha is the fastest, mineral spirits is neutral and "paint thinner" is the slowest. None of them affects the cure time however.Howie.........

    the best thinner for poly is called free flowing paint thinner. inmost cases the label will say low odour paint thinner ,the cut should be about 5% dust your first coat spraying first across the grain and then ,while still wet spray again with the grain .let dry over night and repeat but a bit heavier coat. let it sit overnight again then apply you 3rd coat ,which should be the final coat  .

   You shouldnt have to wait more then 24 hours for danish oil i never have and never have mishaps. As for thinner i dont know you could apply with a brush then tip off by holding your bush near vertical and lightly draging it across the surface. This will level brush marks
