We've sourced a super convenient single-use packet for setting your brush knots into the handle of your choice. Each packet contains 1/2 gram of Silicone adhesive. That's enough for 2 or 3 brushes, depending on the size of your knots.

Don't use too much!! If you apply too much, when you press your knot into your handle, you may see the adhesive squish up the sides of the knot and pop up out of the handle - that's no good! Stay conservative - worst case scenario a knot falls out and you have to re-glue it. Much better than ruining a knot.

After using these packets, you can tape off the cut corner and save them for future use. Just don't let air get into the packet!
5-10 minute work time -- 24 hours for full cure.

Works as advertised.

Easy to use, exactly as advertised

Just as described, enough for 2-3 brushes, depending on how much space you are filling and your knot size. I needed to affix a 20mm and a 24mm and had enough left over for at least one more brush. Good hold so far! Would recommend


Customer review

Single Use & Time Sensitive! I ordered two packs a few months ago. I used part of one, taped the edge over, and put that and the unused pack in a sealed Ziploc. Today, maybe three or four months later, the silicone in both packs is rock hard and unusable. I suggest ordering only one pack at a time (unless you're doing multiple brushes at once) and also assuming that one packet cannot be preserved. So in essence you are paying $2 for a few small gobs of silicone. Might be better to buy a larger more airtight dispenser pack from Amazon or wherever so you can access the silicone as needed in any time span after purchase.


Customer review

This adhesive was easy to use and held knots securely to my brush handles. Using two pea size globs of adhesive, I was able to easily glue a knot to a brush handle. I later decided to change out the knot in the handle and after removing the knot, I only had to do a small amount of scraping to remove the remaining adhesive residue before gluing the next knot into that handle.
