Boiled linseed oil offers excellent protection. I coated 20 ft deck over trailer until it quit soaking in. Used 4 gallons. I only did it once and trailer is now 20 yrs old. Never replaced a single board. I don't even have a single board with any rot! I'm a firm believe. I don't care what anybody says, I go with my personal experience. It works!
I completely agree with you. I made a butcher block style countertop and used boiled linseed oil on it. I did 10-12 applications over 2 weeks and let it cure for a week in the summer heat before using Varathane Ultimate water base over it. Several very thin coats of the Varathane before I installed it. It's now 7 years later and I've never had to do anything to touch up. Not one stain no water marks not even hot pans leave a mark on it. Anyone that doubts BLO needs to learn how to apply it properly.
When I lived in Arizona I used polyurethane on outdoor furniture, after one summer it was disintegrating, literally falling off. Started using a finish that was linseed oil and some resins. When I moved 3 years later, linseed oil coated stuff in the yard still looked great. Now all I use are polymerized linseed or tung oil based finishes, they take a few days to dry and you have to do multiple coats, but they are non toxic and last. Really a no-brainer for wooden handles. I live in Virginia now, I will have to see how well it works in the constant humidity and rain.
Thank you so much for doing this experiment. I bought untreated pine for a series of terraced raised gardens. Because I’ll be growing food, I do not want any toxins in the wood. I was going to use Boiled Linseed Oil and wanted to confirm it would work. Thank you again!!
Boiled linseed oil and mineral spirits work great on ATV plastics too! Tried it on my "weathered" 2005 Yamaha Rhino and made it look new again. Still looking good after 1 month of heavy use. Thanks for the videos John.
We live in a log home at about 6,000ft here in NW Wyoming. Sunlight is devastating to just about everything exposed to the elements. I use nothing but a 50/50 mix of mineral spirits (or Turpentine) and boiled linseed oil on the exterior log surfaces. For deck, railing, and wood trim I use a 1/3 each mix of mineral spirits, BLO, and Olympic Elite high VOC transparent stain.
Mixing pine tar in with the BLO will give the wood better weatherproofing than BLO alone. Pine tar also has anti-microbial properties that inhibit mold and fungus growth. I like a 2:1:3 ratio of pine tar to BLO to turpentine mix, which is what I apply to wooden arrows I make, but you can play around with the mix to suit your taste. In case you're wondering, a pine tar-BLO finish won't be sticky as long as you wipe away excess after applying it.
boiled linseed oil. . . The key word being oil. You are saturating the wood with oil. As we all know, water and oil do not mix. It may not be the most hearty protection, but it only makes sense that Water will not be able to seep in where the oil is.
I, like you, disagree with people when I hear that BLO offers no weather protection. It actually protects wood quite well as you've demonstrated for us. It does have to be reapplied though to maintain protection. For the best protection possible, apply BLO to wood as follows: Once a day for a week Once a week for a month Once a month for a year Once a year for life
I actually repaired some pinewood beams with cracks in them with wood filler, and I was at first gonna paint them white, but I like the result of the filler so much that I'm going to make the pillars ofmy roof transparent with BLO, I just wonder, should I maybe first use sanding sealer? How can I make sure it lasts longer? just put on more coats?
Add a 5% melted candle wax to 50% acetone or lacquer thinner, and 45% boiled linseed oil stirred up. This will give deeper penetration and a water bead when it rains!
george lowellohhdgg63nnd I don't remember off the top of my head, but it was probably around 4 coats. I fully saturated it with the first coat until no more would soak in, and then applied one coat each day until no more with soak in.
If you want even more BLO to absorb into the wood on the first coat try using a heat gun or hair drier to heat up the wood. Once you have the wood warmed up then saturate it with the BLO until it will not except anymore. I think this works best on the first coat and I just use normal room temperature for the second third and continued coats. Thanks for making the video John.
What your seeing is more that BLO keeps wood looking better. It is a fact BLO has poor water resistance. Just setting wood out in weather and saying oh the part looks good with BLO is not in any way scientific. If you need prod the BLO is only water resistant do this. Take two pieces of the same wood treat it with BLO. Weigh it. Then expose it to water or just heavy humidity even, then weigh it. It will be heavier due to water intake. This is scientific proof. BLO is better than nothing and will protect against a little water etc. it also makes wood look good. But it’s bottom rung water protection. It’s even worse against water vapor. Why do you think table tops aren’t finished in it. It’s not cause it’s not easy. Wipe on wipe off. It’s because it water spots. But if the protection level is good enough for your needs then continue using it. It is easy.
What damages wood the most is moisture not being able to escape....such as will normal paints. BLO allows wood to breath which is why it's so good and why wood maintenance with BLO will last forever. When wood is saturated with BOL it can't absorb near as much water, mix that with the fact that it breathes, and you end up with a very good wood protection.
Water doesn't destroy wood. Rot does. If BLO prevents rot, then it doesn't matter if it allows the wood to absorb some water. It also allows the water to escape again, unlike sealants.

poindeml .hi.i apply linseed oil but my floor is stiky .not drying...
How to dry now?plz reply me thankx
Najam Ali Pure Linseed oil will stay sticky. Boiled linseed oil does not dry sticky.

You wipe away the excess of any applied finish. Have you ever read the instructions on a can? 🤯
I redo all my garden tools handles with this every year, love the stuff

Good test! I treated my oak wine-barrel planters with BLO & Mineral Spirits (just 1 coat..inside and out). Hope they last.

For the best protection possible, apply BLO to wood as follows:
Once a day for a week
Once a week for a month
Once a month for a year
Once a year for life
It’s not that it gives it none it’s just not much. But definitely makes it look better.
@@willhill9188It gives great water protection you just have to apply enough to soak deep and allow enough time for it to cure completely
Appreciate your sharing this test...very helpful!

BLO does offer good weather protection for about 2 years.....but it can mold between the wood and protective layer.
Mix BLO with some zinc oxide
Interesting because I’ve read many times that linseed oil itself helps form mildew. Maybe after much longer and versus petroleum options??
if it didn't work we wouldn't be using it for 5000 years
some people just gotta hate!
Thank you thank you.
Wonder how the puddin’ tastes like after a few years
Would blo be a good choice to coat a birch walking stick I carved?
Good pudding 😎.

Will this work on decks? Won't the wax make it slippery? How does it hold up in the sun?
Ok so it did some protection, but still not great.
How many coats of linseed oil did you apply? Thanks.
