Hey guys, I have 2 brushes that need some work. The first is acrylic and then knot just popped out again. It was well cleaned twice before and I tried using the DAP aquarium sealant and some GE Sillicon II caulk and both eventually loosened up and came out. I think I am going to use the aquarium sealant again but would like suggestions how to make it 'stick' better? The other brush is wood and the knot came out of that one some time ago and I use the aquarium sealant on this one. this one is exactly the opposite. the knot just won't come out. Any ideas how to get this knot out? Thanks
I cut my knots mostly flush, then dremel them the rest of the way out. I use two part epoxy to glue them back in. There are several tutorials around here. I will see if I can find some links.
I basically do what @stingraysrock does. I use my Wen rotary tool, starting with a drill bit in the center, then spiraling out towards the side. Sometimes this will get it all out. If I happen to get a stubborn knot, I'll make a hole with the drill large enough to finish with a burring bit. I also use epoxy, but sometimes GE clear silicone. This will allow you to remove the knot in the future, if needed.
DO NOT STEAM TO REMOVE KNOT! I tried it. It ruined the color of my handle. ---> http://theshaveden.com/forums/threads/finally-jumpin-in.34103/
Here is a thread with some video links to a reknot I did some years ago. http://theshaveden.com/forums/threads/another-re-knot-for-shawna-video.27590/#post-478515 And as Steve mentioned above, some handles do not work at all with the steam method. I used steam once, had no problems, then found out there can be problems, so have not tried again.
The first silicone I used was the white, but I switched to the clear. I have done more than 100 brushes with it. I have only had two that came out, and I am pretty sure that the reason was that I did not use enough. What I do now is: 1. I make sure it dry fits the hole well. 2. I completely cover the inside of the hole with a thin coat of silicone. 3. I put a dab on the bottom of the knot. 4. I press the knot into the hole and pull it out to see that it is enough. 5. I turn the knot a quarter turn and put it back into the hole. 6. I make sure it is straight and that there is no silicone squirting out. 7. Set it aside for at least a day.
I love these discussions. I have brushes from both Jims and they are excellent: The razor ain't too shabby either.
I guess I failed to mention that I want to keep the knot and reuse it. Boy does the aquarium silicone hold well!! Either that or it is just hard to grab the knot. It is a wooden handle that needs a little love so I am not sure that steam will be good for it. Frank
