Hello, I just stumbled across this forum while looking for some expert advice on finishing a walnut table I made last year.

Its a circular table made up of “pizza” shaped sections
So far I have finished it with multiple coats of danish oil but as the people I made it for put a lot of things on it its warn and water marked quite badly.

I have sanded it back and then rotex sanded to 320 so its super smooth.

Could someone recommend a good durable finish that doesn’t darken it to much but gives it a more robust surface then the danish oil I have been using.

It has to be done in situ as I cant take it back to the workshop so ideally something that can be applied over the course of one of two days and not one coat a day for the next 5 days etc…

As far as filling the grain goes, can I oil / wet sand it with tung oil using a orbital sander before finishing with the appropriate oil/wax/varnish?

Many thanks in advance.

Polyurethane would be your best option in my opinion. I prefer wiping it on, but that would require multiple coats over a number of days. Since that isn’t an option, brushing it on will be the way to go. Water-based poly will be less darkening than oil.

As for grain filling, unless you are trying to achieve a mirror finish, I wouldn’t worry about it. And if you are trying for a mirror finish, it’s going to take more time and work than you’ve got in this situation.

You will get a fairly good protection from polyurethane. You can’t rush a finish so take your time a do it right and let it dry/cure. Thin coats in room temperature should dry in 2-3 hours and if you use Cabot polyurethane, all you need is two coats.

Here is another vote for waterborne poly. I like this one, but you pretty much have to order it from Target Coatings. Also, add the CL100 for even greater resistance to abuse.

Just a word of caution, waterborne poly has a tendency to raise the grain a fair amount, so be prepared to sand until it is all absolutely sealed. Personally, I like wipe on poly. The stuff dries really quickly so many many coats can be applied in one day.

Thanks guys!
Im in the UK so cant get hol dof the USA product from Target Coatings or Cabot easily. But there is a product from Bona that I have looked up that sounds like it may be worth a try.

Thanks again.

I’d use a poly on it too. You could do your tung oil-grain fill to get that stunning grain look but I don’t think I’d follow that with poly for at least a week to 10 days. Poly isn’t going to play well with it unless it’s completely cured and pure tung doesn’t cure fast. That table does seem to warrant some time in finishing. Very good looking build that one…

Use caution with the orbital sander prior to adding finish . It can leave “curly queues ” on the finish that will show up when you add any kind of stain
