Product Information
Full details
The Amtech 12mm paint brush (G4300) is designed for DIY enthusiasts and homeowners seeking a precise, reliable tool for detailed painting projects. Featuring a no-bristle-loss design and high-quality tapered filaments, it offers exceptional control and a smooth finish; however, its narrow 12mm profile is best suited for small touch-ups and detailed work rather than covering large surface areas.

FAQs
Can this brush be used for oil-based paints?
Yes, the synthetic filaments are designed to perform well with both oil-based paints and varnishes.
Is this brush suitable for painting large walls?
No, the 12mm size is designed for detail work. We recommend a 50mm or 75mm brush for large wall areas.
How do I prevent bristle loss?
The Amtech brush features a no-bristle-loss design, but you should avoid forcing the brush into tight corners which can strain the filament fixings.
Should I soak the brush in water before use?
For emulsion paints, a slightly damp brush can help with paint flow, but ensure it is not dripping wet before you start painting.
Is this compatible with the Amtech G4305 series?
Yes, both belong to the same Amtech professional range of brushes, though the G4305 is a larger 25mm variant.
Troubleshooting
Bristles appearing splayed or deformed
Wash the brush in warm soapy water, reshape the head while wet, and let it dry in a clean, ventilated area away from direct heat.
Paint buildup at the base of the ferrule
Soak the brush in a compatible brush cleaner or solvent for 10 minutes and gently comb out the residue with a wire brush or paint comb.

Setup, Compatibility & Care
Before the first use, gently fan the bristles to remove any factory-loose filaments. To maintain the brush, always clean it immediately after use according to your paint type: use warm soapy water for emulsions or the appropriate solvent for oil-based paints and varnishes. After cleaning, reshape the bristles by hand and allow the brush to air dry while hanging it vertically or laying it flat to ensure the shape remains intact for future projects.
