I have two full flow hives I have recently assembled and they look awesome. I am in Utah and winters here generally require two brood boxes. I purchased two more brood boxes and am now considering my wood treatment options. I instally wanted to use tung oil to bring out the red cedar color, but in researching hot wax dipping I was lured it long lasting benefits. I found a local contact to do the hot wax dipping, so I won’t be trying it myself.
So my questions: Is WRC (Western Red Cedar) already weather resistant enough that just applying tung oil is sufficient? Would hot wax dipping be overkill? Does tung oil look better over time?
My understanding of hot wax dipping is that it lasts 10-15 years (depending on the environment). How often does tung oil need to be reapplied?
I haven’t done tung oil. I have done Boiled linseed oil and was not impressed with the results. I have not done either on cedar. I have waxed dipped my hives. Very few of them are cedar, but I’m sure a few are as I used to be a carpenter and used scraps to build hives. I cook them in beeswax and rosin and that does seem to last about a decade or so. It seems to depend on the grain of the wood. I dipped them in 2004 and some still look like new and some are pretty weathered. I know that’s not a real comparison, but my guess is the hot wax will out last the tung oil by quite a bit.
I would DEFINITELY go with the hot was dipping if you can. I don’t think it is overkill at all. It is hard to find people with long experience of Tung Oil on WRC hives, but I think that Matt @beethinking has been using it for several years. If he doesn’t chime in here, you could send an e-mail to support@beethinking.com and ask - several of their employees keep bees in cedar hives and probably have Tung Oil experience. Their customer service is VERY helpful, so I am sure they would give you an answer.
In researching general woodworking web sites, I have a figure of resealing about every 2 years. Some people say that you may need to sand lightly before resealing, others just apply more seal on top. I guess it depends on what state your wood is in at that time. I only sealed my hives late last year, so I don’t have much exposure on my hives yet, and southern California weather is pretty gentle.
Thank you for the recommendation, Dawn. I sent an email to that address and Rebekah responded. I have included her response below:
Thanks for taking the time to reach out, and for your great questions! While we are not terribly familiar with the hot was dipping method, this is a practice generally used on pine since it rots easily. Western Red Cedar is what we call the 20 year wood for our hives because it can generally withstand the weather for that long.
I can’t attest for the color of the wood following hot wax dipping, but
tung oil does a great job preventing natural graying of the wood, and brings out a great cedar glow, and does increase the longevity of the wood. We would normally suggest applying it once per season.
One concern I would have with wax dipping would be that it would greatly reduce the breathability of the hive. Bees naturally inhabit porous tree cavities, which allows them to self regulate temperature and humidity within the hive.
One bottle of tung oil should be good 1 application on 2 complete hives.
I hope this helps, and please let me know if there is anything else I can help you with!

hot wax dipping is definitely more expensive and much harder to achieve. However it is a far superior way to treat the wood. The difficult is that you must completely submerge the box in wax and rosin at around 120C for 10 minutes or so. the wood must be under the molten wax until all of the moisture in the wood boils out and is replaced by the wax. The wax penetrates 100% throughout the wood. Most people who hot wax dip have giant tanks that hold over maybe 100kg’s of wax. It can take an hour or more just to get the wax up to temperature and it is potentially a dangerous thing to do. So it’s not just something that can easily be done at home.
I built a shallow fry wax dipper- but even for that I needed over 10kg’s of bees wax and 4kg’s of gum rosin. I ‘fry’ each side of the box one at a time.
If you are interested in hot wax dipping the easiest option is to try and find a commercial beekeeper who does it and see if they can dip yours for you. In the USA there are several suppliers who offer very affordable wax dipping. In Australia there are a few suppliers who provide hives already dipped.
TC, I’m also in UT and was wondering who you found to wax dip your boxes? Did you end up going with the wax or tung oil? How did it turn out for you? Thanks.
Tough question. I like the preservation qualities of the wax, but not necessarily the looks. I was hoping for something natural looking, which it is, but I was hoping it would have retained the natural red cedar color more. Instead, it is much more gray looking. Almost like old weathered barn wood.
Oh, gotcha. Yeah, that’s less than ideal. I wonder if you stained the wood with an oil-based stain and then sealed it with the wax it that would result in a nice final product. I’ll run that by Nathan. Thanks for the info.
@Michael_Bush Michael, I have recently purchased an ideal box, it was treated before I bought it, the person whom did it used linseed oil with the wax. He is a second generation commercial beekeeper, only about 60kms away, so a similar weather climate as we have. @carrgo I wonder if the linseed oil would have stopped the Cedar from going a grey colour, as it’s also added to the Tung oil. Thus maybe it’s the linseed oil that’s preserving the natural colour of the Cedar???
In five years the worlds proven crude oil supplies run out.i dont expect you to believe me.
Thus paint runs out or is too expensive.hot dipped waxxed hives thoroughly penetrated with wax last upwards of thirty years.in my humble opinion we should all be forming beek groups and hot waxxing all our hives.
I watched a big florida beek and just by coincidence i saw his hive setup and a truckload of new unassembled hives roll in on a flatbed.they were all waxxed.it makes no sense at all to be painting a hive but its also dangerous and a big investment to get into waxxing thus its best to do it as a club so all can afford the tank,burner,fuel and wax purchase and spread out the cost.
My first hive was painted,all other hives ive purchased have been waxxed.i suggest all manufacturers get ahead of the curve now before its too late.
So I am in Australia, what are our options here? Wax dipping I think is out or at least it’s no where near me. Do I treat all the wood first? Then like a varnish or oil or something to bring out the natural texture of the Flow Hive 2+… I am a bit lost here…
Yes, I wasn’t thinking oil… having experienced that with other woods I certainly won’t be going down that road… but say I want to bring out the wood grains for a more natural look would that be a tinted varnish or stain or what??
Dummies guide with arrows and neon and stand here signs would be appreciated…
Do I put it together first then paint or paint all of it then put together?
