linseed oil /Tung oil floor finish?
« on: August 02, 2011, 08:27:52 pm »
Hi,

I'm about to put some finish on some PINE flooring I put down.  IN a a perfect world I would have put down another species of wood and another surface coating, but my funds are extremely limited  and I happen to have 2 gallons of boiled linseed oil and 1 gallon of raw linseed oil.  I would like to mix the 3 together with 3 gallons of paint thinner or citrus solvent and add Japan drier and use that as the first coat just to let the wood soak it up so I can use less Tung oil .  I will then cover with coats of thinned tung oil.

THe main purpose for the linseed oil is I already own it but I wont use it if it is foolhardy to do so.

THoughts????

All I can say is my experience has been that raw linseed oil takes forever to dry.

I'm sure someone with more experience or technical knowledge will add to this.

I share Doug's concern, but I do not have any actual experience with Linseed oil on a wood floor.

My thought is that mixing the raw with the boiled and then thinning it 50% and then adding Japan drier will help with the drying issue.

Linseed oil won't provide any protection for the wood. The local tavern tried it.....looked like crap in 1 week.

I realize the linseed oil wont do much, I am only thinking of using it because I have some and so the wood wont soak up as much tung.  I will follow up with tung oil as stated in my first post.

You don't want Tung oil either.
Oil finishes do not build up enough film on the surface to provide protection like a polyurethane will.

Ed, that depends. Much of what is sold as "Tung Oil" is actually thinned polyurethane. If the can says something like "100% Tung Oil", then that's what it is. But if it says something like "Tung Oil Finish", then it's just a thinned polyurethane product. I would advise against using it on a floor, however, simply because you're not getting as much bang for your buck. You can buy plain old polyurethane, thin it 50% with mineral spirits and end up with the same thing (or at least something very similar). Or you can do what I do - use the polyurethane undiluted to finish your floor. That would be my recommendation.
The sooner you fall behind, the more time you'll have to catch up.

THe problem with poly is that I am doing this on pine.  No matter what I do it will dent and scratch.  I feel an oil will roll with the abuse better and certainly be easier to recoat a few years from now....

Some poly finishes are very tough.

Try a google search for 'gym floor polyurethane'.

An example:

(For use on softwood floors.)

I wouldn't use the linseed oil or Tung oil combination on the floor neither. A water-based poly product is Gymcoat as well, I've heard of it used up here a lot. Not sure what they recommend for wood species, could check it out online.

To get the raw linseed oil into the wood you need to thin it with turpentine 50%, apply, let stand for a few minutes and wipe excess off. Do two coats, and dry 24 hours each after wiping down. Then apply a third coat full strength and wipe down after a few minutes and dry 24 hours. If you don't wipe the excess each coat you will have a sticky mess. I have used this method on small wood projects and I have never had it go sticky. Used on cherry, walnut, birch, ash. I would not attempt a floor, no way.

Pre-commercial thinning pays off. :)

I used Tung oil on my red oak floor - rubbed it in with a hand sander and then an oil based varnish (can't remember the name of it) finish.

No dogs and no shoes allowed so it still looks good 15 years later.

     I think it will work just fine.  I'm not a fan of polyurethane finishes although I do use them occasionally.  I prefer an oil finish.  I make muzzleloaders occasionally, when I have the time.  A very good finish for  the guns is several coats of thined boiled linseed oil followed by a couple of coats of formbys low gloss toung oil.  Thin the linseed oil about 50/50 with turpintine I have found that mineral spirits doesn't work very well.  I have tried the raw linseed oil before and like everybody has said takes forever to dry.  It might be worth a try though.  '
     As far as an oil finish on a floor, one that I have seen and would like to try one of these days is just a mineral oil finish.  Evidently it takes a lot of coats, but the oil is supposed to really soak in and not show wear like a polyurethaned floor.  Personally to me polyurethane usually looks like a thin layer of plastic over the wood.  It does have it's place of course.  But, I think anytime you can get a finish into the wood and harden rather than just a surface finish you are better off.

Carpenter, I appreciate your using linseed and tung on gun stocks but the work it would involve on a floor would deter a sane man.

from what I read, hard coat poly coatings and soft pine floors do not mix well.  It will peel up/crack where the floor is dented or even with seasonal movement.  Reason why century homes with wide plank pine floors have been oiled for generations.  Some stories have it that "oiling of the floors" was a chore nobody wanted in the household and was often given to a child as punishment.  If the kids were good, the wife got stuck doing the job on Sundays after church.   Them 'ol times 'eh  :D
I just layed down a white pine plank floor/ceiling for our loft.  It took a couple of full days to plane and t 'n g it, then about 15hrs to face nail it.  I still have to hand scrape it before finally oiling it.

I suspect using linseed oil will make a mighty slick (slippery) floor. I know what it does to small wood working projects, it turns the wood quite slippery and smooth for a spell until it dries really well for a few days or weeks. You may even find yourself wiping it down several times for the first couple days as it will bleed from the wood.

If you need to use the linseed oil, do it this way:

Mix linseed oil, mineral spirits and a spar or alkalyd-resin varnish in a 4:4:1 mix. No dryer. Brush on a generous coat and let dry for a few days. light sand and tack. mix another batch at 8:8:1, add a little dryer if you want and apply as many caots as you see fit (2-3 would be good). after full cure (2 weeks min.) follow up with a few coats of floor wax to bring up the gloss. should offer good protection from water and wear and is pretty easily maintained. can give you more details if you nedd them

Thanks guys,

I will now skip the linseed oil and do at least one coat of tung oil thinned to 50% and top it with "Hard wax oil"
