question about gluing a knot

[Galhatz]

I finally went a head an glued the knot to the handle. I used a silicone adhesive so if needed I can undo it and re-do it.
The handle is a rubberset 4, aluminum. I use two quarters to create a shelf. I just used the glue around to keep them and seal the area. As for the knot, I put a dab on the base of the knot, not around it or anything like that. It stays put.
Is it recommended to put glue also around the knot or all the way up the handle? I keep reading here "less is more" and I can see how I can create a mess.
On the other hand, nothing is preventing water to accumulate slightly above the knot base and I don't like the idea of standing water.
Any thoughts?

Most of the water will be gone after you shake or squeeze the knot. Capillary action should take care of the rest.

I have one brush with no glue at all. The knot swells up enough to keep itself in place. I have let it dry out enough to remove it, once or twice. So far it seems to be fine.

don't worry about it. Squeezing and lightly shaking the bristles will remove any excess water. The air will take care of the damp that remains on the bristles

A dab of epoxy is all it takes for a permanent hold. With silicone adhesive you need to be a bit more generous ensuring that the entire base of the knot is covered in silicone with enough excess to push up the sides around the outside of the knot's epoxy base. Since silicone never hardens like epoxy this extra adhesive is needed to create a seal, similar to a gasket, around the entire base of the knot. After it has cured it will be difficult but not impossible to remove and will be impervious to water.

When I am testing a knot I use a small pea sized amount right in the middle of the shelf and push the knot in. When I am setting a knot for good I put a thin coat of adhesive covering the entire shelf, using the applicator nozzle to spread it around, and then another small pea in the middle for good measure. I let it sit for about a minute and then install the knot, applying steady pressure and rotate the knot back and forth 90 degrees to ensure even application. I have had a knot fall out using my testing method, but have not had a knot fall out using my semi-permanent method. In fact I did remove a knot after using the heavy adhesive method and it took a good minute of pulling (not tugging, but strong, steady negative force) to get the knot to release.

How long do you recommend letting the knot sit after adhering it to the shelf?

If you used epoxy, the package should tell you a cure time, which can vary from epoxy to epoxy. I typically just give it 24 hours.
