Product Information
Full details
The Cromar 3-inch laminating brush is an essential tool for professional fiberglass installers and DIY hobbyists who need precise resin application in restricted spaces. Its primary benefit is the ability to reach deep into tight corners and mold details where standard rollers fail, ensuring a smooth, consistent finish. While this brush is highly durable, users should note that it requires diligent cleaning immediately after use to prevent resin hardening and ensure long-term usability.

FAQs
Can this brush be used with epoxy resin?
Yes, it is compatible with most standard laminating resins, though you must use the appropriate solvent for cleaning based on your specific resin type.
How often should I replace the brush?
If properly cleaned and dried, the brush can last for several projects. Replace it when the bristles become frayed or permanently distorted.
Is this suitable for large flat areas?
While it can be used, a roller is significantly faster and more efficient for large, open surfaces.
What is the best way to store the brush between uses?
Clean it thoroughly with solvent and store it in a cool, dry place, ideally hanging or lying flat so the bristles are not compressed.
Does the brush work with gelcoat?
Yes, this brush is effective for applying gelcoat to complex areas where spray equipment cannot reach.
Troubleshooting
Bristles are stiff and clumped after storage
Soak the brush in a fresh batch of acetone for 15-20 minutes and gently comb out the loosened resin residue.
Bristles falling out into the wet resin
Ensure you are not applying excessive pressure against sharp mold edges; use a light dabbing motion instead of scrubbing.
Pros and Cons

Setup, Compatibility & Care
Before initial use, check the brush for any loose bristles to avoid debris entrapment in your laminate. Ensure you have the appropriate solvent—typically acetone—ready for the cleanup process.
Care Instructions:
- Use a designated container with solvent to rinse the brush immediately after use.
- Work the bristles with your fingers to ensure all resin is dissolved from the base of the ferrule.
- Hang the brush by the handle to dry, ensuring the bristles maintain their natural shape.
- Do not leave the brush soaking in solvent for extended periods, as this may soften the adhesive holding the bristles.
