Thread: Knot falling out?

So I was in a local store the other day looking at their stuff while I was waiting for my supplies to come in, and someone returned an unused badger hair brush because the knot was coming out of it. Manufacturing defect. I was looking at brushes already and the woman told me if I wanted the one with the defect I could have it for 5$... 90% off. I said sure, figuring I could somehow fix up a 50$ brush for less than 45$ and still come out ahead.

Anyways, to the point. The knot doesn't come all the way out, it's still in but it rotates and pops in and out of the handle when you apply any pressure. How would I go about fixing this? I assume I'll need to somehow take it out completely, clean the inside of the handle a bit, then glue it back in, but if someone could walk me through how to do it I'd be grateful

Oh, and the names of any materials, namely the epoxy or whatever else is used to glue the knot in.

Thanks in advance!

You will need to sand the old adhesive out of the brush pocket in the handle and scuff off most of the adhesive from the knot base. You need a waterproof non foaming (no urethane glue) glue that is waterproof. A waterproof slow set epoxy will work good. No particular brand, just waterproof, and a slow set. No 15 minute epoxy, go with 4 hour set. It bonds better. Something like this....

Super Glue Corporation | Super-Glue//Epoxies | Waterproof Epoxy Adhesive

Then just mix you epoxy, put a fingernail sized dollop in the brush pocket and push the brush firmly into the pocket. You want some glue to squish up out of the pocket. Just wipe it off with a damp towel. That way you have no air bubbles in the base. Let it cure for at least 24 hours before you use it, 48 hours would not hurt. Clean, glue, use. All there is to it.

Sounds easy enough to do. I'll pick some epoxy up later today. Thanks!

I've done a bunch of these, and if I could just recommend a different glue here . . .

What you really, really need to use is a 2-part, 5-minute epoxy like Devocon or Loc-Tite. These glues work really well, are waterproof and easy to control and clean up. I don't recommend Superglue or anything like it, as it's really not so easy to work with and can make a huge mess of your handle.

Just as well that I didn't get a chance to go out then. I'll take a look at the different types of epoxies tomorrow and pick up one or the other. Thanks!

Actually I think the link is referencing the superglue brand which also makes an epoxy. I too recommend an epoxy, I personally use a slow set rather than 5-minute, but to each their own.
