A year ago, I trusted your advice after looking at both arguments online. After one Canadian winter, though I am disappointed with the waterseal fading, I must say that all my deck boards have remained flat and solid, so thanks!
Thank you, My thick old head took a few times of watching it but when I did it clicked and I understood. Your explanations were good and well explained. Thank you. Bob H
I'm glad you showed a good amount of examples, I learned to fasten wood projects the other way around (taught wrong or forgot what I was taught) either way I am redoing my front deck and this convinced me to try bark down. Thanks for sharing.
Thanks for the great video. I've been watching different videos arguing bark side up/down because I'm getting ready to install a new deck. Bark side down makes more sense to me since the center of the tree is the denser wood. So as the less dense bark side dries out it will cup downward as you show.
Hi First name Last Name, I am glad you found this video before you installed your deck. I am sure as you travel a round you will see where others have installed there boards and find out they are cupping up. Thanks for watching.
THANK YOU John, much appreciated video and i like the proof on of concept, i always thought it was the complete oposite but i must admit i am removing an old deck at the moment and the most rotten planks are the ones cupping, obviously i guess. I will build the new one using that technique !
Very informative. I just watched another video from a deck installer who did exactly the opposite. But, the proof is in the seeing. I'll be building a deck soon and I'm glad I saw your video.
Thank you and great video! I don't mean to criticize as I may be incorrect, but we all benefit when we engage thoughtfully. My thought is that the smily face of the grain should go upside-down, opposite to how you suggest. My thought is that as cupping occurs it will shed the water. If fasteners were installed closer to the edges on both sides in pairs wouldn't this keep cupping to a minimum and prevent fasteners from not holding? Thanks!
Thanks for your comment. You would think that it would not cup if you installed the board bark side up because that is the way it grows but in my experience it is just the opposite. Even using good fasteners the board will cup. Thanks for watching.
Thankyou for your awesome, informative video. I wish I saw this a few months ago because now I'm seeing cupping but thought it was due to one screw in centre of board. Is there any way to get it flat again or reverse it? Thankyou again from New Zealand.
You also might mention another way to extend the life of a deck and that is by sealing the ends of each and every board with a paraffin based sealant. I bought mine online. I’m having to replace a bunch of boards due to the ends rotting. Live and learn.
Would also like to thank you for answering an age old question. I’ve been a carpenter professionally for 50+ years and I never knew bark side down. It makes the most sense.
I build and repair furniture. I will be replacing the the deck boards at my house soon. I appreciate your video correctly explaining the grain and cupping. 90% of the videos I’ve just watched on UA-cam are wrong. Bark side down is proper. Thank you again.
Hi Philip Guhl, I am glad I could help. I am sure you will get many, many years of service. Thanks for watching. Please subscribe thank you Fix It John.
OK, So I'm no carpenter, but doesn't the wood curl with grain therefor cupping up occurs when the bark side is down. At least that is what the other posts are saying. I'm looking at my new 2x6 PT and that is what is occurring on loose boards. So, I see what you are showing but it is contradictory to everyone else. Of Course, they could be all wrong as well. But, I think I will go bark side up ( smiley upside down) and let any cupping occur on the bottom and crown on top for water shedding. Again, I'm not a carpenter and could have this all wrong
Hi Backfist97, Yes I know there is some debate over crowning for different species of wood. Always do your research because you are the one that has to live with it. Here is an article that I found that may help you. I wish you the best and thanks for watching. www.thespruce.com/deck-board-installation-1825145
Yes! I built a PT fence and ran out the PT 2x4 it rotted out but the fence slats were still good. I think that if I were to build a deck I would use PT girders PT joists and vinyl or composite decking boards. Just a thought. For the girders and joists use that ZIP system flashing tape. That will keep the water from soaking into the top of the boards. Just trying to give ideas. Thanks for watching.
You may not have a problem because Redwood and cedar are more stable and are likely to lay flat with little or no checking or cracking. Hope this helps.
Fix it John thank you. Got me all nervous. But that’s a very good tip. I’ll make sure to pass along the knowledge to my son. So when it’s time to build a deck for his family. He would know what to do.
You mention a curve cut. I'm guessing that this is a pressure-relief cut done with a table saw? I'm thinking of using PT 2x6 lumber for decking and would like to avoid cupping issues. So, bark-side down and maybe 2 or 3 "curve cuts" on the bark side, if I'm understanding this correctly, along with 3 screws at each joist?
Hi Sly Dog, Thank you for your question. This can be done by making kerf cuts on the underside of your deck boards. Create these small grooves by using a table saw. This method will relieve the surface tension in the area. Make sure that the blade widths are about 1/8 inch, and are evenly spaced. An example of a kerf cut is to go into half-inch size when your boards are about 5/4 inches thick. Here is a link on how to install deck boards. www.thespruce.com/deck-board-installation-1825145
@@fixitjohn Did I miss it? I looked at this article and didn't see anything about bark up or bark down.. I'm only on my first cup, so maybe I just missed it..
22 inch on center is too much. From my research 12" to 16" on center is to code. I fell through my deck, 2½ft high, which was built before I bought my house. No injuries. I'm almost finished. Replaced rotted joists, added more joists, and joist hangers and taped the tops. Finishing up big job of deck boards. Octogon shape with deck boards going from outer edge to center. Like a pizza cut in 8 slices. Between the rain storms and 100°+ temperatures, I'm almost finished, about 10 more boards of various lengths and 22½ degree angles.
Doesn't it depend on lumber type, heat (plenty of hot weather) and humidty? yellow pine in SE GA, bark side up. I'm finishing up replacing rotted joists and deck boards o 20' x 20' deck. I fell through 2½ ft tall deck, 3 times. No injuries due to my "cat-like" reflexes. 65+ year old grandma.
Redwood and cedar can be layed either way usually using the finished side up. When laying pressure-treated pine I prefer bark side down. At any rate, I am sure that your deck will look good for many years. I would try to seal the deck once it dries out in a month or so. I myself have developed those cat-like reflexes but it is after I hit the ground. Thank you for watching.
The cupping is just the characteristics of the wood. For years they always said crown up. Meaning ring down for water shedding and laying better. When you mill a log, how many boards have the bark side? Most of them are inner or center boards. I am just replacing top deck boards after over 25 years. I have zero cupping or twisting. I just have rotted edges because the previous owner left no gap.
What about wet pressure treated 2x6s that are already cupping in a smiley face .. the way it was on the tree.. so you go to install the board and you're installing it cupped. you're saying that that's going to reverse itself over time?
Fix it John, how do you repair a scratch on a deck with pressure treated wood, (non stained.) It's fairly minor, but bugging me. Will sanding take off the pressure treated too much?
Hi Victoria, sanding would work just, be sure you do it evenly so as not to create a low spot. The sanding will discolor it making, it brighter but, that will fade and match the other with time. You would have to sand halfway through the board to remove the pressure treatment. Here is an article that explains the treatment. The pressure-treating process, lumber is sealed in a tank, and the air is extracted, creating a vacuum. Then a solution containing chromium, copper, and arsenic is added. Because of the vacuum, the chemicals are carried deep into the wood.
Bark side up is suppose to help it from soaking up water. Right at end of video you can see the boards he says are laid correctly look how weathered they are compared to the ones right beside that are bark side up. The bark protects the tree when its growing right? Then why would you expose the open side of the lumber?
Who done this walkway bridge ffs their eyes must've beem painted on 😂😂 the join work is like a kindegarden lego set 😂😂 looks like it was done 5 years ago by trained monkeys not 1 year ago 😂
