Paint Brush Profix radiator brush 50×8 mm model 43035 for narrow surfaces

Profix radiator brush model 43035 features a compact rectangular 50×8 mm head designed for precise paint application on radiators, pipes and other narrow or confined surfaces. The small profile allows access between radiator fins and into tight gaps where larger brushes cannot reach. The brush is intended for use with standard radiator paints and primers during renovation, maintenance and touch-up work.

Advantages

The narrow 50×8 mm head provides controlled paint deposit and reduced risk of drips when working in vertical or angled spaces. Its compact shape improves visibility of the working area and helps keep paint off surrounding surfaces. The brush construction balances flexibility for even coverage with enough stiffness to work around fins and pipes, making it suitable for repeatable, neat results in confined areas.

Suitable for

• Painting radiators and between radiator fins
• Coating pipes, valves and narrow metal profiles
• Spot repairs and touch-ups in tight or recessed areas
• Applying radiator-specific paints and primers in renovation projects

Key specifications

• Head dimensions: 50 × 8 mm
• Rectangular compact head shape for narrow surfaces
• Suitable for water-based and solvent-based radiator paints and primers
• Designed for controlled paint application in confined gaps
• Ergonomic handle for one-handed control in small workspaces

How to use

Before use, ensure the surface is clean, dry and free of loose rust, flakes or grease. Stir the paint or primer thoroughly and, if necessary, thin according to the paint manufacturer's instructions. Dip the brush lightly to avoid overloading, remove excess paint by tapping or wiping on the container rim, then apply with steady, even strokes along the surface or between fins. For best results, work from top to bottom on radiators and allow recommended drying times between coats. Clean the brush after use with water for water-based products or the appropriate solvent for solvent-based paints, and store it dry.

Usage recommendations

For precise and durable results, choose a paint or primer formulated for radiators and metal surfaces, follow the manufacturer's preparation and drying guidelines, and maintain the brush by cleaning immediately after use to preserve its shape and performance.
