    I did not see Loctite in this trial.
    I will never buy Gorilla Glue products. They failed multiple times. Their only good side is the ads.

    Subscribed, love your channel. Please do a thorough test with HDPE (HDPE to HDPE adhesion) using adhesives such as 3M Scotch Weld and Loctite 3035 etc etc. Thank you.

      Great Channel! I noticed GOOP is shown in the middle of the display of adhesives, but was not tested. Was there an issue with using Amazing Goop? I've used this product quite a bit and was really hoping it would be tested.

        I decided not to test it since it didn't really fall into the construction adhesive category

      Shoot most of the time you have one of the products I use, but no LePage PL Premium. Awesome videos though, not complaining.

      I have never seen a YouTube channel who puts so much effort in to stuff like this. I don't need this knowledge, it doesn't really apply to me right now but I know if I ever need any strong adhesive, I know to go for 3M. Although, I know 3M is well renowned for its adhesive, especially it's VHB tape. Thanks a lot Project Farm, your videos are interesting even if they don't apply to many of your viewers.

      Instead of soaking with water, soak with gas, JB weld has issues with that kind of chemical exposure, at least I tried patching a gas tank with JB weld on a 87 Chevy, it leaked 2 days later.

      I like your videos however you got to be less dry with the numbers and just trying to get to the point faster. Mimi make a second video that you can link that goes over the numbers of people care about that but for most people we just want the results not so much the accounting of it

      Suggestion : since the wood failed before the adhesive, we really don't know what the actual numbers are.

      How about using simple clamps on both ends of the boards instead of through-bolts? There are clamps with teeth, if smooth jawed clamps still can't hold against your winners there.

      I bet this caused Gorilla glue stock to go down and JB Weld stock went up! LOL!

        A coworker one time prepped an area of a barge I needed to do some welding in on a Friday so that Monday morning I could travel out and get right to welding ,,, well not only did that knucklehead torque down every one of the bolts instead of putting a handful full back on , he used 5200 around the entire circumference 😠 it took me hours of beating and prying to get the hatch open ! I'm pretty sure it took 10 years off my life 😂

          why 3M? it looked like JB Weld did much better at 493 pounds.
          out of curiosity could you redo a challenge between just the two, JB Weld and 3M pull test and really bolt onto the wood and see how much higher than 461 lbs they can withstand?

          • Project Farm
            Project Farm   2 weeks back

            Great point. JB Weld is definitely stronger but of the construction adhesives, 3M seems to be the best.

          I would like to see which sealant maintains it's original integrity in a high amonia environment with a minimum of 25ppm to a maximum of 50ppm in an enclosed atmosphere. The walls are pressure treated plywood.

            You should do a video on whether or not catalytic converter cleaners work. There is cataclean, the laquer thinner method, and others. This could save people thousands in parts, as it's one of the harder to replace parts if you dont have a bolt on converter.

              I've never tried 3M 5200 due to the cost. For wet applications, it's clearly the winner and a product I'll be trying in the future. Thanks for the video!

              How is there so much variance between the same products? Does that really mean I could use it and not know if its gonna hold 800lbs or 1800lbs?

                For the last test when adhering to a smooth surface you should scratch the smooth surface for better adherence unless there is an aesthetic reason not to scratch it up.

                Being from Scotland we dont get any cool products like JB Weld or 3M, unless you want to get it shipped over which is a pain if you are in a hurry. I will get some sent over just incase..........

                No Sikaflex
                Glue to concrete. These adhesives get used for applying wood to concrete all the time.

                      Yeap, what I expected, keep JB Weld in your tool box and around the shop. I've never had any luck with any of those adhesives.

                      You need only two tools: WD-40 and duct tape; if it doesn't move and it should, use WD-40, if it moves and shouldn’t, use the tape.

                          Thanks for the positive comment. I hope hit helps viewers save time and money and motivated manufacturers (if the even watch the videos) to improve their products. I've wasted a LOT of time and money over the years buying products that just don't deliver good results.

                        Every time I see one of this guys video pop up, I say "no way, he is going to test those, I want to know that answer" and then he does a thorough testing and review like consumer reports, but for free. Thanks.
