Paint Funnel Filter

Paint preparation

The Paint Funnel Filter strains coatings before they enter the gun cup, removing skinned material, dried flakes and site debris that would otherwise block the nozzle or leave inclusions in the film. Straining is the cheapest defect prevention available in spray work and takes seconds per fill. Use a fresh filter per colour change and match mesh grade to the coating.

Paint Funnel Filter FAQs

What types of paint can I filter with this funnel?

This filter works with all types of paints, including latex, acrylic, oil-based, urethane, and lacquer, giving a smooth, debris-free finish.

How fine is the filtration mesh?

The filter uses a fine mesh (around 100-200 microns) to catch debris, dried paint particles, and contaminants while allowing smooth paint flow.

How do I clean the filter after use?

Rinse the filter with the appropriate solvent (water for water-based paints, thinner for oil-based paints), then let it air dry before storing.
