For anyone wondering why I didn't just summarize the results at the end - I knew most people naturally just skip to the end searching for the final tally/ summary on a video like this - and even this videos analytics show a huge spike at the end - that's from people searching for the summary, which actually isn't there. I made the video in such a way that anyone wanting to see the results actually has to watch the video in full and take notes. The reason I had to do this is because the algorithm sees the value of a video by its watch-time. - if watch time is low the algorithm determines the video wasn't good and buries it. That's just how it works. In all likelihood, the very fact that the algorithm has shown you this video is because I didn't provide a summary. I had to make it that way because this video took a long time to produce and costed at least $100 in material, and I wanted the video to be successful.

Fantastic video thank you so much for investing your time and money to preform and share this test! Strongest to weakest: Tied for first place: 1. Fibafuse with taping compound - no crack in joint, (joint stronger than gypsum board and does not fail) 1. Fibatape with taping compound - no crack in joint, (joint stronger than gypsum board and does not fail) 1. Straight flex with taping compound - no crack in joint, (joint stronger than gypsum board and does not fail) 1. Fibatape with hot mud - no crack in joint, (joint stronger than gypsum board and does not fail) 1. Fibafuse with hot mud - no crack in joint, (joint stronger than gypsum board and does not fail) 1. Striaght flex with hot mud - no crack in joint, (joint stronger than gypsum board and does not fail) Paper tape set with hot mud - Hairline crack at 20 lbs (joint stronger than gypsum board and does not fail) Paper tape set with taping compound - Hairline crack at 17 lbs fail at 18 Mesh tape set with hot mud - Hairline crack at 16 lbs (joint stronger than gypsum board and does not fail) Mesh tape with taping compound - Hairline crack at 13 lbs (joint stronger than gypsum board and does not fail) Fiba tape pressed on then topcoat - Failed at joint at 12 lbs Mesh tape pressed on then topcoat - Failed at joint at 8 lbs Notes: Boards failed around 21 lbs on average Takeaways: Hot mud makes joints less prone to cracking compared to taping compound. But taping compound is still more than adequate. Straight flex, and Fibafuse are stronger than paper tape, but paper tape is still more than adequate for many cases.

This is epic. After 30 yrs plastering I’ve never seen tests like this. Awesome!!!

I use fibrafuse and fibratape red. With all purpose. I love that you have done this. Drywallers have been talking trash on my videos for months. I've never had a call back in my career. They are the 2 best tapes period. Especially embedded and prefilled

A summary paragraph or statement at the end of such a video is always helpful.

Hi...i m drywall pro from croatia. Few notes from this part of world. We are always v grooving those but joints, than we do prefill with a gypsum based material, or hot mud how you call it, than on butts we apply fibafuse coated again in gypsum based material. Third coat is not gypsum based material, we are doing that coat with a mud which is softer just because of easier sanding. Since drywall sheet itself is gypsum made than the best joint is if you use gypsum based coat. You have made great video. We need more like this on you tube. Final note...if you ever have enoufgh time made a few tests on dynamic pressure, since theese were just static pressures.

Getting ready to use FibaFuse for the first time and wanted to know if the marketing was for real. Seems like it is so this is cool. Also, wasn't sure about hot mud with it, your test shows no problems, so I'm excited to use it. Thanks for your efforts.

Great video, love the Dexter Destructive testing you did here. I've seen similar in fiberglass testing. I like the Fibafuse 15:47, it looks like CSM fiberglass that will be omnidirectional in strength opposed to the mess. Very thin to lay down even though they all worked well for their task. Again very interesting and great job.....

Great test. Thanks for taking the time to make this video.

Really well thought out and thorough test...thank you!

This test and the comments from others gives me more confidence in using the fibafuse for other than small repairs. I'm repairing ceiling cracks down the long seams and I want to minimize the chance of the cracks returning. Fibafuse and quikset seem like a viable option.

Good comprehensive test 👍

gotta appreciate the science you've done here!

just went fully auto with fibafuse and joint compound. used to use mesh and Sheetrock for everything then finish with joint compound so this video makes me feel a bit better about using fibafuse. great video. thanks for your efforts.

Great work love the fibafuse.

FibaFuse user since 2014!

I use fibafuse with setting compound. Sheetrock 20/45/90 etc awesome video

Very informative! Thank you sir.

Great video. I was thinking a control was missing but in the end the drywall failed before many of the joints. I would love to see another test that tests all joints to failure. Either replacing the drywall with plywood or gluing some plywood to the back of the drywall preventing the drywall from ever breaking anywhere but at the joint.

thanks for your hard work sir

Great test

I have a vaulted ceiling with collar ties up top and the 135 degree angle joints that keep splitting. Thus the reason I'm here. Structure is less than 5 yrs old. 2x12 rafters. Has nothing to do with load but everything to do with extreme cold temps during the winter. 2 inch closed cell followed by 8 inch open cell. Well insulated. I'm not a fan of mesh but my drywaller claimed it would hold just fine. My plan now is to scuff it up good and use the fibafuse with the Durabond 90 and Strait-Flex Super-Bond Joint Compound. Great video. Thank you.

Not sure if you have one. Can you do an extension on this video. Do a test with 90 min and mesh and fiba mesh with own adhesion. Great video, goid information. Thank you

That's an interesting overview. What kind of drywall are you using? 5/8 type X (regular weight)? the stronger the drywall the better you can tell apart strong vs weak joints.

Do you have a link for that sanding vacuum thingy? Is it an attachment? Thank you very much for showing this. I've never done drywall before. My house has all wood paneling from the 70s but I need to add something to the walls in the bathroom and was trying to figure out what to use and what tape to use and how to apply it. Any recommendation on what to use behind glue-up shower walls as well as around direct-to-stud shower walls? Can fibafuse be installed without a taping compound underneath? I wasn't clear on that. So, a compound is just put over it?

Great comparison

Nice vid . Fibafuse performed well.

In Germany, you usually buy the FibaFuse like tape (although it doesn't have that brand-name here) but I have seen people use the fiber mesh tape. I have never seen paper used here. FibaFuse like tapes are very strong and very easy to apply - it's porous, so there is no danger of blistering like with paper. The only thing you need to look out for with it, is not to sand through it. Since it is so thin and so interwoven with the mud, it is easy to overlook it and sand right through it. And then it is obviously completely useless.

I wish you did some with the joint prefilled with Durabond before taping

Was the drywall cut completely in half and separated and then taped and muddled or just scored down the middle? Also drywall will never be under that kind of stress? Maybe in ceilings with blown-in insulation that got wet and is pushing on drywall that way. Usually drywall shifts with the structure side to side or up and down. Not pushed against it but i mean i guess any test is better than no test 👍🏼

Awsome man! would you mind if i attack my sequence video. I want to explain in another language

is fiba fuse the strongest in terms of joint strength?

Ever since me and my work partner found fibafuse we've been using it for all except corners (which we'll do with paper, because we can't get the creased fibafuse here). Much better than paper tape, and mesh is homeowner garbage.

good effort... not so sure that a bending load is the load that causes most drywall cracks though. Could be shear or tensile during cycling/fatigue.

Beautiful work. Best tape test on youtubd...Randy S

When you used the mesh tape directly on the wall, what compound did you use over it? Mesh tape requires hot mud. It won't bond with drying mud, causing your joint to fail prematurely.

Awsome man! I have a question, what is your step by step sequence for each days when you are doing a big job. (from taping to finish and sanding)

Thanks for making this comprehensive video comparison. I’m confused about the first couple of tests. You said “no compound” was used for the mesh and fine mesh tapes, but it looked like the tapes were mudded over. Did you mean that you didn’t embed the tapes in compound but topped them with compound? If so, what mud did you use in these specific tests? If my understanding is correct based on the rest of the video, you didn’t test the performance of the regular and fine mesh tape using self-adhesion topped with setting compound. Thanks again for the video!

Excellent prep and presentation on your part. I'm a DIYer out of necessity and my house is 60 yrs old so I'm beginning to see various settling cracks. I watched hundreds of videos to learn about which material I should use on a repair for a vertical corner-bead crack and decided fibafuse was the best. Will be using a setting compound/hot mud. Am I doing the right thing?

Great comparison. What is the most cost effective ?

Very interesting test. The results didn’t seem to be that much different overall between the various tapes. Will you be providing a summary of your findings?.

I realize this is 2 years ago, but I purchased fibrafuse tape. Do I then use the regular compound with the green top?

Ima use the fibafuse. I like that it lays thin. No need for excess building

This is "Project Farm level" testing... thanks very much.

FIBAFUSE: THE FUTURE IS NOW! 😂🎉 For everyone wondering what the summary is: they ALL work, OBVIOUSLY! FibaFuse is just the easiest! Paper takes way more time and skill for nothing.
