Big Horn 19408 High Pressure Glue Injector with 2 Brass Tips

Works well. Wish it was a little finer applicator but robust enough to last

So I purchased a DriTac repair kit and this injector kit together. The syringe and needle/injector that came in the box kit worked well for 8 holes (there was a bunch of air pockets in my engineered wood floor!), then it bent, was clogged and would no longer work. I switched over to this Big Horn product and immediately saw an improvement; in my ability to put pressure on the syringe, on the leverage holding the Bog Horn syringe/handle, and especially on the brass tips! It's important to clean out the syringe and tips, but this product rocks! The only thing I wish was different is I had purchased a much larger syringe. This will certainly work, but you may have to fill it multiple times to fill a large space. One other tidbit of info, it may be me, but I noticed I was able to get a much better flow when keeping the brass tip just a smidge off the floor. I was probably blocking some of the flow by pushing the brass tip against the floor a bit much, but once I raised it 1/32 or 1/16 from all the way in, the adhesive/floor leveling liquid flowed much more quickly. Highly recommended!

This injector is tough, an do can tolerate a lot of pressure. Be advised that it is only for water based adhesives - I used Bostik:s Best adhesive, which is solvent based. It worked well initially as I was able to inject 1 1/2 tubes under my wood flooring. When I tried it the next day, the solvent caused the barrel to swell enough that the plunger woulln't seal. If you are using aqueous based glue.such as Elmer's or most wood glues, it would work exceptionally well.

I noted a bathroom vanity drawer with a horizontal split on the piece of wood that the side of the drawer. It wasn't completely split down the side but there was a noticeable gap. How could I get some glue into that space?This injector came to the rescue. I put some Tightbond III in it, squirt it in from the side, and put two clamps on the drawer side, letting it cure for 24 hours. It worked like a champ!Cleanup was very easy, just disassembling it to its component parts and rinsing them off in the sink with some lukewarm water.

You can’t inject glue into a crack with a round tip. It would take a prism shape to create enough back pressure. And you can’t just inject down or up into a drilled hole with hardwood floors because there is a layer of felt and old floors use boards on a diagonal with gaps, not plywood, so that further complicates things.These old floors squeak because the base boards bow side to side due to drying out, or due to cracks in them, or due to nails that hit along the side of the joist. You really have to get up in there and use thin shims with glue to quiet them (or bend the nails). You can also screw up into the hardwood in difficult cases, or slap 2x4’s with adhesive and screws up alongside a joist.But even with access from below in this manner it is amazingly difficult to isolate and stop these squeaks. It takes time and effort. I don’t see how any of these other quick and easy technologies are going to do much good. There are no easy answers here.

Let me fully endorse the use of this glue injector for filling gaps under hardwood flooring. What a great technique! I installed bamboo flooring in our upstairs hallway and for whatever reason, in one spot the boards didn't get glued to the floor properly during installation. Walking over the spot was annoying because you could easily feel it under foot. It felt like walking on a trampoline!I drilled a tiny little hole near the center of the problem area, right on a knot, so you can barely see it. Then I filled it with wood glue using this injector. I was shocked at how much it took! Nearly an entire bottle of glue went into that tiny hole. I marked it off with masking tape so we wouldn't step on it for a few days and voila, worked like a charm! Feels nice and solid underfoot now.

This is so useful and I wish I had found it sooner.

Used this to fill voids in my floors. Warming the caulk makes it easier to inject. Takes quite a bit of effort to get the stuff into the void. The 1/16th inch hole ends up getting enlarged but I used colored caulk and the holes aren't very noticeable.The problem is with the screw on top and screw on handle. When you unscrew the top to reload, it's difficult not to also unscrew the handle. Biggest problem is with the threads on the cap. It's cheap plastic and the cap pulls off quite easily. Need more sturdy threads.While it worked ok, I'd probably try a different kind next time due to the design issues.
