IGM LEP-SL1 Silicone Glue Brush Kit – 24 mm + 13 mm + Spatula
The IGM LEP-SL1 silicone glue brush kit is a complete tool for precise glue application in detail work and finishing. It includes 2 brushes (24 mm for medium applications, 13 mm for fine details), a silicone spatula with smooth and serrated edges, and an integrated tray with pouring notches. The soft silicone bristles ensure even distribution without residue on unwanted areas. Ideal for deep mortises, dovetail joints, flat tenons, and high-quality finishing in professional and craft woodworking.
The LEP-SL1 Kit offers two brush sizes to cover both medium-sized applications and extremely detailed work. The 40 mm flexible handle allows access to deep mortises and complex joints with ease. The soft silicone bristles do not shed fibres, ensuring clean glue application and no visible residue on the final joint.
Main Features
- 2 interchangeable brushes: 24 mm (medium applications), 13 mm (fine details)
- Soft silicone bristles that do not retain glue residue
- Double silicone spatula: smooth edge for precise scraping, serrated edge for texturing
- 40 mm flexible plastic handle for access to tight spaces
- Silicone tray with pouring notches for excess glue
- Easy cleaning: dried glue peels off the silicone or can be rinsed with lukewarm water
- Zero fibres: silicone bristles do not shed onto the joint
- Ergonomic and compact for comfortable handling in detailed work
Who the LEP-SL1 Kit is suitable for
| User profile |
Use case |
Technical reason |
| Cabinetmaker / artisan woodworker |
Complex joints, mortises, dovetails, details |
2 brushes cover the full range; double spatula scrapes excess without marking; 40 mm handle reaches deep spaces |
| Bespoke furniture maker / restorer |
Finishing work, custom creations, antique restoration |
Zero-fibre silicone bristles ensure visibly clean joints; serrated spatula creates texture when needed |
| Detail-focused hobbyist / craft workshop |
Small but precise projects, carvings, delicate assemblies |
Easier to use than traditional brushes; short handle reaches carvings; spatula solves unexpected situations |
Not suitable for:
- Large-scale applications (>1000 cm² per session) — the brushes are small and the work becomes slow; use the LEP-SL3 roller for speed
- Very fluid or low-viscosity glues — they may run off the silicone bristles before drying
- Gluing with limited access (<25 mm depth) — the 40 mm handle may be too long; use LEP-SNL applicator kits

Frequently Asked Questions
What is the difference between the 24 mm and 13 mm brushes?
The 24 mm brush is ideal for medium-sized applications (standard mortises, medium joints, flat tenons). The 13 mm brush is for fine details, narrow carvings, complex joints, and hard-to-reach areas. Both have the same silicone bristles but different widths to suit different spaces.
Is the 40 mm handle long enough for deep mortises?
Yes. The 40 mm handle allows access to mortises up to 50–60 mm deep without bending and without the handle touching the workpiece. For even deeper mortises (>70 mm), use the spatula to push the glue precisely to the bottom.
Can I use the brushes with epoxy glues?
Yes, but pay attention to the open time. Two-component epoxies (5/30 minutes) remain fluid enough for application. For ultra-fast-setting epoxies (2–5 min), prepare the kit immediately before mixing. Silicone does not react with epoxy, but you need to work quickly.
Do the bristles shed onto the joint?
No. The silicone bristles do not shed like the fibres of a traditional brush. The silicone remains intact even after 500+ applications. This ensures visibly clean joints without visible fibres.
What is the serrated spatula used for?
The serrated edge creates a textured pattern in the glue when needed to increase mechanical adhesion (on smooth or painted surfaces). The smooth edge scrapes excess glue without marking the wood. Choose the appropriate edge according to the type of joint.
How long does the brush last before it needs replacing?
With correct use, each brush lasts for 500+ applications (about 3–6 months of intensive use, 5–6 days/week). For hobby use, service life extends to 2–3 years. Inspect the bristles every 6 months — if they appear compressed or deformed, it is time for replacement.
Can I use the spatula to scrape dried glue from painted wood?
Yes, with caution. The silicone spatula is soft and does not scratch lacquers or paints, unlike metal. Use the smooth edge and light pressure to scrape dried glue from painted surfaces. For fresh glue on raw wood, you can apply more pressure.
Is the kit easy to clean after work?
Yes, very easy. Pour excess glue into the tray through the notches, then rinse all components with lukewarm water. Dried glue peels off naturally from the silicone without effort. Total cleaning time: 2–3 minutes. If you wait until the next day, the dried glue peels off even more easily.
