Product Information
Full details
The Cromar 4-inch laminating brush is an essential tool for professional fiberglass installers and DIY enthusiasts who require precision during resin application. It is specifically engineered to reach complex geometries and tight corners where standard rollers fail, making it perfect for detailed topcoating and moulding tasks. While its specialized design offers superior control for intricate work, it is important to note that this brush is intended for detail-oriented application rather than large-surface coverage, which is better suited for wider rollers.

FAQs
Can this brush be used with epoxy resins?
Yes, the brush is compatible with standard epoxy resin systems used in laminating.
How should I store the brush?
Store the brush in a cool, dry place, ideally hanging it by the handle so the bristles maintain their intended shape.
Is this brush reusable?
Yes, provided it is cleaned thoroughly with the correct solvent immediately after use.
Will the bristles melt when used with polyester resin?
No, the brush is specifically manufactured to be resistant to the chemicals found in standard fiberglass resins.
Can I use this for applying gelcoat?
While it is designed for resin laminating, it can be used for precise gelcoat application in tight areas if handled carefully.
Troubleshooting
Bristles shedding during application
Before first use, gently flex the bristles and remove any loose strands that may have come detached during shipping.
Resin hardening in bristles
Soak the brush in fresh acetone for 10-15 minutes, then use a wire brush to gently comb out the hardened resin.

Setup, Compatibility & Care
This brush requires minimal setup; simply ensure the bristles are clean and free of loose debris before first use. It is compatible with all standard polyester and epoxy resin systems. To ensure the longevity of the brush, clean it immediately after use using the appropriate solvent, such as acetone, and shake off excess liquid before letting it air dry. Avoid leaving the brush submerged in solvent for extended periods, as this may soften the adhesive binding the bristles.
