Testing Shop Made Wood Fillers!

Wood Fillers are often used to fill small nail holes, small gouges, and even joint gaps and other defects in furniture and other wood projects but how these fillers work with wood stains and wood dyes or even topcoat finishes like varnish or hardening oils is not well documented so this video is a start to that using both Red Alder and Walnut and comparing some DIY grain fillers with on commercial grade filler to see how they all work. Which wood filler for large gaps is a question I commonly get, so we'll be testing using a large drill hole. I also get asked about stainable wood filler, so we'll be testing also.

[@Frandalicious66]

Thanks, I never took into account the existing wood darkening over time 👍🏻

[@user-wo7vp3le4d]

Finally I found someone explaining things correctly xx thanks a lot

[@LogHouseFarm]

Thanks for providing a place for links, and for offering your time as a speaker, very kind of you 👍

[@loua6127]

One of your BEST videos yet Colin! Thank you Sir!

[@MCsCreations]

Pretty interesting results, Colin! 😃 Thanks for testing!!! Stay safe there with your family! 🖖😊

[@Sulkanator]

Great video, Colin. Thank you for taking the time to do this testing.

[@niteshade295]

I have always used saw dust from the same timber mixed with wood glue And I find it better then any filler

[@sapelesteve]

Very interesting video Colin & the results speak for themselves. I also agree with you about going darker rather than lighter........... 👍👍😉😉

[@kevinfowler7144]

What would we do without Colin? I don't even want to imagine it. Hands down, best woodworking teacher on the internet.

[@Penster-Elle]

I keep a selection of wood dust in every shade I have ever used. I store them in small 'Spice Jars' so that I can match a wood colour with the right sawdust. I have had great success with using these along with a slower-setting (it says that it's a 60 second set up, but I have found it a little longer, which is ideal) CA Gel glue. It doesn't shrink, is sandable and takes a good finish; whether that be waxes, oils or varnishes. I don't think I have ever stained it, but only because I have never stained any wood.

[@roccit]

Wow, you're waaaaaaay more forward thinking than I am. I'll just sand some part off my neighbor's deck railing to get the right dust when I need it :)

[@cobberpete1]

Yep, I do exactly the same. I've got about a dozen little pots of different wood dust / colours

[@huynguyen-tx8gf]

Oookiiojjn. N.

[@deependz3231]

3M CA Gel glue.- 0.7oz- $60.00

[@Mighty_Atheismo]

@@roccit DAAAAALE!! HE'S BACK AGAIN!

[@mgeez6147]

Agreed , I like Colin's advice. I have a wooden inside door that the dog has scratched and I have tried sanding out scratches. The scratches still show thru the paint. I was just trying to find something to fill the scratches so they dont show thru the paint. Also I took to covering doors with acrylic to keep dogs from scratching and that works for a good ten years or so.

[@minicooperusaf4624]

Thank you Colin, good test project. I learned a lot.

[@joonyaboy]

Glad to know I wasn't the only one having a hard time with matching wood filler

[@roberthalaska3030]

Genius again! I learn a lot every time thanks Colin

[@robertmadden7536]

Thanks for this Colin interesting results

[@dianafertig2188]

Thank you for sharing this interesting project.

[@castletransport]

Thanks for the video. Very interesting because I'm looking at turning pallets into furniture but I want to make sure I fill holes so this helped. Thanks!

[@projectwood7221]

never saw that done before, great work Colin

[@jerryjohnsonii4181]

Thanks for the knowledge about making my own wood filler , Colin !!!!!!!!!!!!!!!!

[@jmadd1000]

Excellent video - thanks for the work.

[@parksmitchell]

I use Rock Hard water base putty mixed with wood glue and colored with acrylic artist paint.

[@markarnold159]

Very informative!!! Appreciate your fine instruction once again!!!

[@petercowell2051]

Thanks Colin, very interesting.

[@ljgault]

I've been using the black CA glue in black walnut and really like they way it works. I just received a bottle of the brown but haven't tried it yet. Thanks for the wood filler test.

[@barneyrubble4827]

Im repairing damaged edges on a black walnut speaker cabinet. I'm guessing the CA isn't thick enough to form and hold an edge till set. How sandable is it? Would drying time permit me to mix with sawdust before application? TY

[@markmccaw4401]

Always appreciate your work. Thanks.

[@Bill.L.Carroll]

Some great methods here, cheers mate 👍🏽

[@satinboardwoodworking1667]

Thanks for the information. I use Timber Mate water-based wood filler with lots of success with stains.

[@georgequalls5043]

Great information. Colin. Thanks.

[@bamadave11]

Ahhh I wish you had done this a couple of weeks ago. Thanks for the info and test.

[@dennisbrown2571]

The guys that repaired and refinished my mom's oak floors used a filler called Wood Wise wood Filler. Was great for staining and finishing.

[@juliehenderson1672]

Thank you. Love your channel. 👍

[@andrewschannel3635]

I like OSMO wood filler, it takes stain much better than the lepages used there, I have also found that you can mix sawdust and water with it.

[@hansdegroot8549]

Very interesting test. Thanks for sharing. You put a lot of time in it. The result is not exactly what you hoped for but nevertheless it's better this than leaving a hole. But the holes you drilled out are very large compared to small nail holes or joint gaps. I think that for those examples sawdust with yellow woodglue will do. When filling bigger holes, such as you showed (I guess they're about 20 mm in diameter, I think I'd use plugs (made from the same wood with a plug cutter) and glue them in.

[@TrailRat2000]

One of my granddad's, I think my dad's dad, use to use a couple drops of gravy browning to darken any of the sawdust and wood glue fillers he use to make. Never knew why, but I suppose if you're making your filler darker that would do it.

[@Mrkozbo]

Thanks! that was very helpful!

[@ilbotteghino]

Thank you for sharing, ery helpful 👍

[@antallaczko8793]

My best recipe is sawdust mixed with Sherwin Williams AC laquer - the single pack stinky PU laquer -. 3 years ago I had a solid beechwood heringbone floor to be sanded and varnished, with gaps of 1-2 mm. My homemade filler is not as hard as the epoxy, not as soft as shellac, and we all know that every glue is advertised to be stronger than the wood. It has the same hardness as the wood - depending on the mixing ratio-. Got the same texture and same colour after the finish sanding and varnishing - 1 coat of Sherwin Williams sand sealer, 2 coats of 2 pack PU. I was happy, the customer - who is a professional carpenter with 20+ years experience 😀 and fitted the floor himself - was happy, his father, who is a builder for more than 50 years was thrilled. Next time I'll try the mixture with Sherwin Williams water bourne, that keeps the hue even better. Both materials have a short curing time, between 30 minutes - 2 hours - depending on the size of the hole, gap - can be sanded. For structural resistance fiberglass can be added into the mixture. In your case Colin, I would try the mixture with sandsealer, as it is a matt finish it should well absorb the Osmo. I'm with painting and decorating for the last 15 years, recently started with woodworking. I learnt a lot from your videos, keep up the good work, stay safe!

[@Don-cs7fe]

You should try Famowood wood filler either in latex or solvent base. It comes in various wood colors & is actually stainable & quick setting. I prefer the solvent based but have good luck with both taking Zar brand stain.

[@davidwvalentine8024]

Logical, methodical, intelligent. There is hope. Lol

[@WeedMIC]

for knots (not so huge as in your video) i drill them out completely at an angle and fill the hole with a dowell. the dowell will look exactly like a knot.

[@jackstanford550]

WeedMIC I’ve done that.

[@nnickers3355]

Nice vid. If your looking for a similar idea comparing different wood species plugs explaining shrinkage as well as seeing how some may take stains etc differently. Thought this was about plugs based on the thumbnail.

[@dhm7815]

Brown CA glue. Thanks. I've used CA because it penetrates cracks all the way to the bottom. I've used it for screw holes where I want to screw and will want to unscrew a wood screw or bolt in the future a few times but don't want to bother with an insert. CA penetrates and hardens the threads in the wood. (After it cures, if I'm using a bolt I run the tap thru again.) But I always had to accept that any stain would stand out bright.

[@W4ldgeist]

You missed to test bone glue and saw dust. That will be great like shellac in terms of handling, but it will dry REALLY tough and strong. It will also take oils, stain etc.

[@jackstanford550]

For variety and by using a combination of colored chalk line chalk you can have a real success matching OR contrasting your work piece. Use yellow glue, CA, etc., but especially epoxy.

[@MangledGuitars]

Very nice buddy

[@antcommander1367]

friends carpenter teacher/master taugh great wood filler. which i use, if theres not commercial one in hand. Excellent, traditional (finnish) and easy filler 1 liter of water, 1-2 tablespoons of wheat flour + sawdust/sanding dust, which should be moistened first. Wood dust are added until the putty is a suitably solid mass.

[@katandpapa]

Excellent video as usual...I love your kind demeanor. You're a good teacher!🇺🇸🙏❤

[@t1n4444]

If you have the time, and you can get the chance to experiment on a piece of identical waste timber, then try mixing sawdust from a drilled hole with PVA and match. We also have stuff called Rustin's Plastic Wood in a fair few shades. Can be stained or drilled as well as. A word of caution ... it goes off really quick. Best to layer it and check match as you go.

[@gilbertrabbe5424]

I was fortunate enough to attend a woodworking show a few years ago where a presenter explained that there is a filler being made that stains just like wood ... just not your wood.

[@jgriff19861947]

I use glue to mix a different color for a high lite to stand out on the wood

[@kennyharris9656]

Trying to repair a broken 2-piece pool cue. What would be best to glue the threaded insert into the end of the cue plastic wood filler, epoxy or maybe something else? Needless to say it will need to stand up under a certain amount of force. Thank you

[@I-Love-Taylor-Swift]

Whenever I see a new Colin Knecht video, I'm like "YEAH"!!

[@jackstanford550]

Yeah. Me too!I really like his videos.

[@thejoshthat]

Same here! Didn’t show up in my notifications, so I’m glad he does the post as well

[@osamaejaimi9192]

if i want to do shou sugi ban do i fill the cracks 1st or do I burn the wood and i fix cracks after ?

[@magnuswootton6181]

Casting with wood filler, id like to give it ago sometime.

[@roccit]

OK Colin, time to do a collaboration with Project Farm guy :)

[@grahammiddo8014]

Thanks Colin. Most informative. As we are all at different stages of woodwork knowledge, could you give some details on dust particles? Is it best for dust from a saw or sander for example. Thanks

[@Jake_Cotumaccio]

I know I’m seeing this a year later but that’s a good question. If you’re using dust after hand sanding, you don’t want it to be too fine, otherwise it doesn’t have any depth and just looks thick paint. I’d use anywhere between 80-120 grit to create that dust, but nothing higher. I personally use a combination of sanding dust and the tiny chips that come from using a sharp hand saw or a rasp. They’re so small that you can move them around like dust but they add some variety of size/shape to the mixture to make it look more organic.

[@tedlofland3446]

Have you tried filling the voids with fine sawdust sanded from the same piece of wood, adding drops of super glue then heating it with a heat gun, sand it, then coat with the finish. The void looks just like the surrounding wood?

[@leonardnoel888]

Well dan Thanks

[@elizabethbeesmer1926]

I am new at this. What do I do when iVe put wood filler on porch and it’s the color sticks out? Can I stain over the top again?

[@WeedMIC]

I use sawdust and hide glue - hoping u cover that mix.

[@andyboybennett]

Colin, the brand is "Starbond". The on-screen text says "Startbbond".

[@williamgomez1354]

I applied natural stain color and the wood filler it's still light, how can I do to disappear that wood filler?

[@Mr_Rick]

Interesting test. I've never mixed Sawdust and woodworker's glue to put in an opening as large as what you show. Normally I use Sawdust and glue for small cracks, etc. I noticed you did not test hides glue and sawdust. I would think it would work well. Have you ever tried it?

[@johncunningham5799]

INTERESTING

[@WeedMIC]

nvr thought of shelac as a binder - will have to try that - oic stays soft nvm

[@sylvaingregoire9262]

I love you comparing diffrent fillers .. but one comment ... could you try one thing for me that i think can change one result dramaticly !! The Lepage filler , to try mixing the color befor it dries !!! After if it’s no diffrent just send me a pm and that will be that . But if it does in fact chages every thing then post an up date video for me please .😉 Thx 👍🏼🇨🇦

[@raz3032]

How do I fix a chip in a Trex deck board?

[@garybouck3389]

Try mixing a little stain into your sawdust filler for better color match. Less is more. Just a little.

[@TheOldBlackCrow]

Kind of off topic here, but can I run melamine through a thickness planer? I have spiral cutting blades. Thanks!

[@toddshinn4955]

It's never a good idea to run anything man made through a planer or jointer. The glues and resins used to hold wood or fibers together will dull and even ruin blades/cutters. Still, I've seen people do it.

[@TacoTeaser]

Could you stain the wood dust before mixing the glue? Maybe get a better match that way.

[@misternewman1576]

No filler, all killer!

[@garryr]

The wood glue clearly spread to the surrounding wood and blocked the stains as well.

[@brianandablo2042]

HELP, I was doing a diy and parts of my board look like a sponge. I sanded and it just gets worse why is that? Look up sanding techniques beginners #13 on KZbin and my board looks just like the thumbnail to that video, I watched the video but didn't find my answer?

[@Semaj.18272]

Ok so I used a wood putty and after adding oil the putty is light ? Whag should I do how can I make those filled holes darker

[@johnraffensperger]

Try drawing over it with a Sharpie marker.

[@ccccen]

ufffffffffffff always glue marks on projects, haven't found a glue that can accept the stain to a good finish. How about the Elmers' stain able glue?

[@9700am]

I have got to admit to not taking into account that the wood will darken with age.. Will try and purchase some brown CA glue, if it’s available here in the U K. 🇬🇧

[@bcwalker1]

How about poly as a filler?

[@Pete.Ty1]

😊👍

[@jolookstothestars6358]

Have you tested store bought fillers?

[@thomasjosejosephjose7036]

You have to name the glue by chemical used. Glues are of different types based on chemicals used .

[@jaredlanny03]

our local wood turner's "club" doesn't have as much as a dilapidated Facebook page.... I can't even find a number, just a few random references in local news articles to its existence.... Are there any of these zoom meetings specific for wood turner's who're looking for new members?

[@urwholefamilydied]

I don't get how the wood glue and sawdust turned out so much darker than the wood?? Wood glue itself dries like tan, and the sawdust literally is from the material. What a strange thing.

[@LuisRamirez-xb3hl]

👍👍👏👏👏👏👏👏👏👏👏👏👏👏👏

[@AusyG]

That's quite a name to have knecht it means servant in German

[@trapshooter6]

[@deependz3231]

For people that stain their wood, not everyone uses a dark stain, so your test is flawed.

[@robertr6675]

Waste of time. What is the point? Different products will always produce different results. So?

[@johnd942]

Dreadfully boring preparation. Just get to it....anybody CAN MIX!!!

[@FranksDIY]

Thanks for the tips Colin. I also tested some with not so great results. I think i'll try that CA glue next time.
