Summary

TLDRThe video provides a comprehensive overview of wood finishes, categorizing them into varnishes, natural oils, and hard wax oils. It explains that varnishes create a protective film over wood, with oil-based and water-based options offering different appearances and application methods. Natural oils penetrate the wood for a more organic look but provide less protection, while hard wax oils combine the benefits of oils and wax for a smooth finish. The presenter emphasizes that there is no perfect finish, as each project has unique requirements, and encourages experimentation with different finishes.

Timeline

  • 00:00:00 - 00:05:00

    The video begins by addressing the confusion surrounding wood finishes, categorizing them into varnishes, natural oils, and hard wax oils. Varnishes, which include products like polyurethane, create a protective film over wood and are applied in multiple coats. The presenter discusses the differences between oil-based and water-based polyurethanes, highlighting their appearance on different wood types and the ease of application. The pros and cons of varnishes are outlined, emphasizing their durability and suitability for high-traffic indoor projects, while also noting the challenges of repair and the time required for application.

  • 00:05:00 - 00:12:47

    The discussion then shifts to natural oils, which penetrate the wood rather than forming a film. Tung oil and boiled linseed oil are compared, with the latter drying faster but darkening over time. Danish oil is introduced as a blend of oils and varnish, offering a balance of natural appearance and protection. The video concludes with hard wax oils, which provide a smooth finish and are easy to apply. The presenter evaluates various products, ultimately stating that while there is no perfect finish, several options are suitable depending on the wood species and project requirements.

Mind Map

Video Q&A

  • What are the three categories of wood finishes?

    The three categories are varnishes, natural oils, and hard wax oils.

  • What is the main difference between oil-based and water-based varnishes?

    Oil-based varnishes tend to give a warmer, amber tone, while water-based varnishes are clearer and dry faster.

  • Is shellac a durable finish?

    Shellac is not very durable compared to other varnishes and is best for low-contact pieces.

  • What is the advantage of hard wax oils?

    Hard wax oils penetrate the wood and provide a smooth finish while being easy to apply and repair.

  • Can natural oils be used on high-traffic furniture?

    Natural oils offer the least protection and are not recommended for high-traffic pieces.

  • What is Danish oil?

    Danish oil is a mixture of tung or linseed oil, mineral spirits, and varnish, providing a natural look with some added protection.

  • How do you apply varnishes?

    Varnishes can be applied by brushing, wiping, or spraying.

  • What is the drying time for tung oil?

    Tung oil can take days to dry between coats.

  • What is the best finish for high-traffic pieces?

    Varnishes, especially oil-based ones, are ideal for high-traffic pieces like tabletops.

  • Is there a perfect finish for woodworking?

    No, the perfect finish does not exist as each project has its own needs.

  • 00:00:00
    today i'm going to simplify one of the
  • 00:00:01
    most confusing topics for woodworkers
  • 00:00:03
    give you actual side-by-side comparisons
  • 00:00:05
    of 12 popular products and answer the
  • 00:00:08
    age-old question if there really is a
  • 00:00:09
    perfect finish to help make sense of
  • 00:00:11
    this i'm going to group finishes into
  • 00:00:12
    three categories varnishes
  • 00:00:15
    natural oils and hard wax oils contrary
  • 00:00:17
    to popular belief varnish is not one
  • 00:00:19
    singular finish instead it's a broad
  • 00:00:21
    group of finishes that create a layer of
  • 00:00:22
    protection over the wood after building
  • 00:00:24
    up multiple coats this is often referred
  • 00:00:26
    to as a film finish so everything you
  • 00:00:28
    see in front of me right now is a
  • 00:00:30
    varnish not just this guy because it
  • 00:00:32
    says varnish on the label varnishes are
  • 00:00:34
    applied by brushing wiping or spraying
  • 00:00:37
    polyurethane seems to be the go-to for
  • 00:00:39
    most woodworkers starting out and
  • 00:00:41
    something like this minwax is a cheap
  • 00:00:43
    and accessible option
  • 00:00:44
    since polyurethanes are oil-based they
  • 00:00:46
    do require a solvent-like paint thinner
  • 00:00:48
    to clean up your brushes if you choose
  • 00:00:50
    that for an application method but a
  • 00:00:52
    water-based poly sometimes referred to
  • 00:00:54
    as a polycrylic gives you the ability to
  • 00:00:56
    clean up using you guessed it
  • 00:00:58
    [Music]
  • 00:01:00
    although i typically use foam brushes
  • 00:01:02
    because i'm lazy so i don't even worry
  • 00:01:04
    about any of that water-based also dries
  • 00:01:06
    faster so you can apply more coats in a
  • 00:01:08
    single day but in my eyes the real
  • 00:01:09
    difference between oil and water-based
  • 00:01:11
    poly is the appearance your piece will
  • 00:01:13
    have after finishing this is especially
  • 00:01:15
    noticeable on the lighter color woods
  • 00:01:17
    you can see that the oil-based
  • 00:01:18
    polyurethane leaves the maple in the
  • 00:01:20
    white oak with a more amber tone while
  • 00:01:22
    the water-based poly has almost no tint
  • 00:01:24
    to it whatsoever on the flip side the
  • 00:01:27
    water-based products leave the darker
  • 00:01:28
    colored woods looking
  • 00:01:31
    also water-based varnishes are slightly
  • 00:01:32
    more finicky and difficult to apply
  • 00:01:34
    because they don't penetrate as well as
  • 00:01:36
    the oil-based if you're looking to join
  • 00:01:37
    the cool kids of woodworking general
  • 00:01:39
    finishes armor seal is a great wiping
  • 00:01:41
    varnish armor seal uses higher quality
  • 00:01:44
    resins which are supposed to result in a
  • 00:01:45
    better finish this is super easy to
  • 00:01:48
    apply it almost impossible to screw up
  • 00:01:50
    you can brush it but most people wipe it
  • 00:01:52
    on because it's already thinned down the
  • 00:01:54
    water-based version of this finish is
  • 00:01:56
    known as high performance okay let's
  • 00:01:57
    pause quickly and talk about some of the
  • 00:01:59
    pros and cons of oil and water-based
  • 00:02:01
    polys of all the finishes these create
  • 00:02:03
    the highest level of surface protection
  • 00:02:05
    because you're basically building up a
  • 00:02:06
    layer of plastic over your piece
  • 00:02:09
    epoxy river tables but since these take
  • 00:02:11
    multiple coats to build up a protective
  • 00:02:13
    layer it will require more overall time
  • 00:02:15
    for a finished product especially when
  • 00:02:17
    using an oil-based product and more dry
  • 00:02:20
    time means more opportunities for dust
  • 00:02:21
    to settle into your piece so you need to
  • 00:02:23
    keep your space reasonably dust free and
  • 00:02:25
    this entire process can take days
  • 00:02:27
    repairing these water or oil based
  • 00:02:29
    varnishes is not super easy and
  • 00:02:31
    typically ends with you sanding down all
  • 00:02:33
    the visible areas to get a consistent
  • 00:02:35
    looking finish again and finally on the
  • 00:02:37
    positive side these are reasonably cheap
  • 00:02:38
    compared to other finishes so when
  • 00:02:40
    should you use these a good oil or water
  • 00:02:43
    based product is an ideal finish for any
  • 00:02:46
    indoor project but where these really
  • 00:02:48
    shine is on high traffic pieces like
  • 00:02:50
    table tops because they can withstand a
  • 00:02:52
    lot of abuse let me get this out of the
  • 00:02:54
    way because i'm sure i'll be asked or
  • 00:02:55
    questioned in the comments every product
  • 00:02:57
    i'm going to show an example i've got
  • 00:02:59
    the full finishing treatment as if this
  • 00:03:00
    were a piece of furniture at a minimum
  • 00:03:02
    all the varnishes got four coats some
  • 00:03:05
    even five to six because finishes can be
  • 00:03:07
    somewhat subjective i got a second even
  • 00:03:09
    a third opinion phew
  • 00:03:12
    and the four wood species being
  • 00:03:13
    showcased are figured maple quarter-sawn
  • 00:03:15
    white oak sapele and walnut looking at
  • 00:03:18
    these four options and the cool hip
  • 00:03:20
    woodworkers are thinking there's a clear
  • 00:03:22
    winner and that's the armor seal
  • 00:03:24
    but that's not armor seal
  • 00:03:26
    yep that's minwax you'll look at that
  • 00:03:28
    the walnut and the sapele look
  • 00:03:30
    surprisingly great and midwax gets a bad
  • 00:03:33
    wrap for looking plasticky but my new
  • 00:03:35
    theory is that's the gloss and the
  • 00:03:36
    semi-gloss products from them this satin
  • 00:03:39
    looks and feels really good and since
  • 00:03:42
    this applies just as easily as the armor
  • 00:03:44
    seal especially when you thin down the
  • 00:03:45
    last coats i'm giving the nod to minwax
  • 00:03:48
    but that's not the end of the story
  • 00:03:49
    anything that accentuates the darker
  • 00:03:51
    woods tends to muddy the lighter woods
  • 00:03:52
    too much if you're looking for clarity
  • 00:03:55
    this will be a recurring theme
  • 00:03:56
    throughout the comparisons on the
  • 00:03:57
    lighter woods it's between the
  • 00:03:59
    polycrylic and the high performance now
  • 00:04:01
    this isn't a perfect comparison because
  • 00:04:03
    i used a high gloss polyacrylic versus
  • 00:04:05
    the satin of the high performance but
  • 00:04:08
    this also highlights what i mentioned
  • 00:04:09
    earlier the poly acrylic is simply
  • 00:04:11
    horrible everything about it looks fake
  • 00:04:14
    and it ambers the maple more than the
  • 00:04:16
    high performance which is the entire
  • 00:04:17
    reason you would opt for a water-based
  • 00:04:19
    finish to begin with so general finish
  • 00:04:21
    is high performance and the minwax
  • 00:04:22
    polyurethane move on another popular
  • 00:04:25
    option in the world of varnish is
  • 00:04:26
    shellac which comes from the secretion
  • 00:04:28
    of the lac bug you can buy ready to use
  • 00:04:31
    shellac or make your own by purchasing
  • 00:04:32
    those bug poop flakes and then mixing it
  • 00:04:35
    with a solvent it is easy to apply you
  • 00:04:37
    can brush it but i like to thin it down
  • 00:04:39
    with denatured alcohol and then wipe it
  • 00:04:41
    on it dries quickly and leaves your
  • 00:04:43
    pieces with a classic looking finish but
  • 00:04:45
    shellac is not very durable compared to
  • 00:04:47
    other varnishes because of the
  • 00:04:48
    durability concerns shellac is not a
  • 00:04:50
    great option for high traffic pieces but
  • 00:04:52
    it's ideal for something like boxes
  • 00:04:55
    shelves or other low contact builds the
  • 00:04:57
    final varnish we're going to talk about
  • 00:04:58
    is lacquer this is typically sprayed and
  • 00:05:00
    there are plenty of options that come in
  • 00:05:02
    a nice rattle can if you don't have an
  • 00:05:04
    hvlp set up like me
  • 00:05:06
    you could also be a crazy person and
  • 00:05:08
    brush it but don't be a crazy person
  • 00:05:10
    lacquer dries the fastest of any of the
  • 00:05:11
    products we're going to discuss today so
  • 00:05:13
    you can build up a lot of coats very
  • 00:05:15
    quickly now one of the nice things about
  • 00:05:17
    shellac and lacquer is they don't
  • 00:05:18
    require a mechanical bond that means you
  • 00:05:20
    technically don't need to sand between
  • 00:05:22
    coats because each subsequent quote
  • 00:05:24
    adheres to the coat below it without any
  • 00:05:25
    assistance when you're comparing shellac
  • 00:05:27
    and lacquer you can see they are
  • 00:05:29
    reasonably close but the shellac ambers
  • 00:05:31
    the maple the most of all these products
  • 00:05:33
    in terms of feel both are buttery smooth
  • 00:05:36
    although you can really feel the film on
  • 00:05:37
    the top of these if i were to choose a
  • 00:05:39
    better all-around finish between the two
  • 00:05:41
    i would take lacquer it's just more
  • 00:05:43
    durable can be used on just about every
  • 00:05:45
    type of build and is very easy to play
  • 00:05:48
    and most importantly is faster from
  • 00:05:50
    start to finish so lacquer advances to
  • 00:05:52
    the final round one last note on varnish
  • 00:05:54
    is if for whatever reason you got
  • 00:05:55
    confused at the big box store and
  • 00:05:57
    accidentally grabbed a 2x4 instead of
  • 00:05:59
    walnut which happens fear not any
  • 00:06:02
    varnish oil or water base can be applied
  • 00:06:04
    over stain once it's fully dried the
  • 00:06:06
    second category is natural oils now
  • 00:06:08
    these provide the most aesthetically
  • 00:06:10
    pleasing and natural looking finishes
  • 00:06:12
    that's because the oils penetrate below
  • 00:06:14
    the surface of the wood unlike varnishes
  • 00:06:16
    that build up a film on top
  • 00:06:18
    application is extremely easy and you
  • 00:06:20
    truly can't mess it up simply wipe them
  • 00:06:23
    on liberally allow time for the oil to
  • 00:06:25
    penetrate and then wipe off the excess a
  • 00:06:27
    second and third coat can be applied
  • 00:06:29
    within a day or so the two common oils
  • 00:06:31
    that are readily available are tongue
  • 00:06:33
    and linseed oil
  • 00:06:34
    pure tongue oil comes from the nuts of
  • 00:06:36
    the tongue tree the downside to tung oil
  • 00:06:38
    is the dry time you sometimes need to
  • 00:06:40
    wait days in between coats but unlike
  • 00:06:43
    linseed oil which we'll talk about in a
  • 00:06:44
    moment it doesn't change color over time
  • 00:06:46
    and is slightly more water resistant but
  • 00:06:49
    if water resistance is a concern natural
  • 00:06:51
    oils really shouldn't even be considered
  • 00:06:53
    boiled linseed oil is often referred to
  • 00:06:55
    as blo this comes from flaxseed and
  • 00:06:57
    dries much quicker between coats
  • 00:06:59
    compared to tongue oil the downside to
  • 00:07:01
    blo is it can darken over time both
  • 00:07:03
    these oils are incredibly easy to repair
  • 00:07:05
    just sand the affected area and reapply
  • 00:07:07
    but wait there's actually a third
  • 00:07:09
    product that is sold as an oil but it's
  • 00:07:11
    not really a true natural oil
  • 00:07:14
    danish oil is an equal parts mixture of
  • 00:07:16
    tongue or linseed oil
  • 00:07:18
    mineral spirits and then a varnish like
  • 00:07:21
    polyurethane the idea here is you get
  • 00:07:23
    the natural look and absorption of the
  • 00:07:25
    tongue or the linseed oil with a little
  • 00:07:27
    added protection from the varnish like
  • 00:07:30
    the poly application is exactly the same
  • 00:07:32
    as the other two oils and gives a really
  • 00:07:34
    great finished look all right so what
  • 00:07:35
    are the pros and cons of natural oils
  • 00:07:38
    visually these are the best and most
  • 00:07:39
    organic in appearance application is
  • 00:07:42
    really easy maybe the easiest of all the
  • 00:07:44
    products but these offer the least
  • 00:07:46
    amount of protection with all those
  • 00:07:48
    factors being considered natural oils
  • 00:07:50
    are best for very low contact builds
  • 00:07:51
    such as bandsaw boxes picture frames and
  • 00:07:54
    shelves definitely not chairs or coffee
  • 00:07:56
    tables if you love the look of the
  • 00:07:58
    natural oils but you want more
  • 00:08:00
    protection you can put a couple coats of
  • 00:08:02
    varnish over the top once it's fully
  • 00:08:03
    dried when comparing these three side by
  • 00:08:05
    side there really isn't a distinct
  • 00:08:07
    difference until you get in close
  • 00:08:09
    the darkest of the three is the boiled
  • 00:08:11
    linseed oil but on something like the
  • 00:08:12
    walnut sapele and even the white oak
  • 00:08:15
    it's almost too dark and looks muddy and
  • 00:08:17
    you lose a lot of that chatoyance the
  • 00:08:19
    danish and the tung oil are very close
  • 00:08:21
    but i'm going to give the nod to danish
  • 00:08:23
    oil for a couple reasons you're getting
  • 00:08:25
    the benefit of a little extra protection
  • 00:08:27
    because the varnish mixed in and it
  • 00:08:29
    dries much faster so the danish oil
  • 00:08:31
    marches on to the finals the final
  • 00:08:33
    category finishes are known as hard wax
  • 00:08:36
    oils now these have become quite the
  • 00:08:37
    rage in recent years if you're
  • 00:08:39
    unfamiliar with this finish they started
  • 00:08:40
    out in the hardwood flooring industry
  • 00:08:42
    and eventually made their way into
  • 00:08:44
    furniture hardwax oils are very literal
  • 00:08:46
    the oil penetrates the surface and bonds
  • 00:08:49
    with the wood fibers and once dry the
  • 00:08:51
    wax creates a reasonably strong layer of
  • 00:08:53
    protection resulting in a buttery smooth
  • 00:08:55
    finish
  • 00:08:56
    application is very similar and easy for
  • 00:08:58
    these two products you can trowel it on
  • 00:09:00
    for larger pieces or simply rub it in
  • 00:09:02
    with a white scotch brite for the
  • 00:09:03
    smaller builds after you let that sit
  • 00:09:06
    for a bit you just buff off the excess
  • 00:09:08
    first up is rubio monaco which you've

    probably heard of unless this is your
  • 00:09:11
    first time on youtube rubio monaco
  • 00:09:14
    markets itself as a one coat finish but
  • 00:09:16
    i've used it enough to comfortably tell
  • 00:09:17
    you it needs a second coat unless you
  • 00:09:19
    want something really flat looking i
  • 00:09:21
    guess rubio dual coat didn't have the
  • 00:09:23
    same ring to it also if you need
  • 00:09:25
    something to fully cure in one week you
  • 00:09:27
    need to add in their accelerator which
  • 00:09:29
    costs more money otherwise it's a three
  • 00:09:31
    week cure time in defense of osmo
  • 00:09:33
    they're comfortable in their own skin
  • 00:09:35
    and market this as a two coat finish and
  • 00:09:37
    there's a noticeable difference between
  • 00:09:38
    the first and second application unlike
  • 00:09:40
    rubio now they recommend 14 days of cure
  • 00:09:43
    time but no extra charge if you're
  • 00:09:45
    familiar with hard wax oils there's a
  • 00:09:47
    third very popular product odes oil this
  • 00:09:50
    is the only finish of the 12 we
  • 00:09:51
    discussed today that i haven't used
  • 00:09:52
    before so i reached out to odis oil and
  • 00:09:55
    they made it very clear they did not
  • 00:09:56
    want to be included in fact specifically
  • 00:09:59
    said please refrain from using us in
  • 00:10:01
    your post fortunately for you whatever i
  • 00:10:03
    do what i want od's markets to finish as
  • 00:10:05
    100 voc free and can be used in food
  • 00:10:08
    safe applications like cutting boards
  • 00:10:10
    now one of the other advantages odis has
  • 00:10:12
    versus the other two is prep with ods
  • 00:10:14
    you can stand up to whatever your heart
  • 00:10:16
    desires unlike rubio and osmo that don't
  • 00:10:18
    recommend going beyond 120 to 150 but i
  • 00:10:21
    always go to 180 with those and never
  • 00:10:23
    have issues let's talk about the pros
  • 00:10:24
    and cons of hard wax oils these are
  • 00:10:27
    really expensive and while our jar goes
  • 00:10:29
    a long way and can finish multiple large
  • 00:10:31
    builds it's still sticker shock
  • 00:10:32
    initially expect to pay 45 to 75 dollars
  • 00:10:35
    as an upfront cost in return you're
  • 00:10:37
    getting the benefits of quick and easy
  • 00:10:39
    applications that are really difficult
  • 00:10:41
    to mess up additionally significantly
  • 00:10:43
    lower vocs or none at all
  • 00:10:48
    these aren't as durable as a varnish
  • 00:10:49
    like poly but if it's good enough for
  • 00:10:51
    hardwood floors it's probably good
  • 00:10:52
    enough for your kitchen table
  • 00:10:54
    and like the natural oils repair is a
  • 00:10:56
    breeze simply sand the area with a
  • 00:10:58
    scratch and then reapply i'm sure you
  • 00:11:00
    guessed it but these are great for any
  • 00:11:02
    type of build large or small even high
  • 00:11:04
    traffic pieces time to pick a winner
  • 00:11:06
    when looking top down at the darker
  • 00:11:08
    woods there wasn't much of a difference
  • 00:11:09
    between the odis and the rubio osmo just
  • 00:11:12
    looked blah
  • 00:11:13
    but a side view reveals a very clear
  • 00:11:15
    winner on the walnut and the sapele and
  • 00:11:17
    poetically enough that's the odis oil
  • 00:11:20
    but here's where it gets interesting
  • 00:11:21
    while youtube would lead you to believe
  • 00:11:23
    otherwise people do occasionally build
  • 00:11:25
    projects out of species other than
  • 00:11:27
    walnut are you sure yeah on the lighter
  • 00:11:29
    white oak in the maple the odis has too
  • 00:11:31
    much of an ambering effect like we've
  • 00:11:33
    talked about earlier and doesn't look
  • 00:11:34
    nearly as good as the rubio or the osmo
  • 00:11:37
    where i honestly can't tell a difference
  • 00:11:40
    i hate participation trophies and split
  • 00:11:42
    decisions but there isn't a clear winner
  • 00:11:43
    here these are all great finishes
  • 00:11:45
    depending on your wood species since
  • 00:11:47
    they all apply the same are very
  • 00:11:49
    expensive and visually have their pros
  • 00:11:51
    and cons i'm gonna settle this debate in
  • 00:11:53
    a future video with a durability test
  • 00:11:54
    between the three they all advance to
  • 00:11:56
    the final round we're left with minwax
  • 00:11:58
    poly general finish high performance
  • 00:12:00
    lacquer danish oil and your choice of
  • 00:12:03
    hard wax oil officially the minwax poly
  • 00:12:05
    is the worst of the bunch in fact all
  • 00:12:08
    four options of poly were really
  • 00:12:10
    underwhelming next to these other
  • 00:12:11
    finishes other than high performance but
  • 00:12:14
    that's a bit of a one-trick pony with
  • 00:12:15
    the maple
  • 00:12:17
    the danish oil has a great overall
  • 00:12:19
    appearance but it's not a good
  • 00:12:21
    all-around finish because of the lack of
  • 00:12:23
    protection
  • 00:12:25
    lacquer is so easy to apply and while
  • 00:12:27
    it's fairly durable it doesn't have the
  • 00:12:29
    same natural look and feel of the hard
  • 00:12:32
    wax oils so are these three the perfect
  • 00:12:34
    finish absolutely not the perfect finish
  • 00:12:36
    really doesn't exist because each
  • 00:12:38
    project has its own needs but you
  • 00:12:40
    certainly can't go wrong with any one of
  • 00:12:42
    these or the other finalists test them
  • 00:12:44
    out wear a respirator buy
