Purdy White Bristle Sprig Flat Brush vs Purdy Pro-Extra Glide Paint Brush

Both are Purdy premium brushes, but they are built for different paints. The White Bristle Sprig is a soft natural-bristle brush for oil-based stains, polyurethane and clear finishes, where it lays down a smooth, level coat. The Pro Extra Glide uses a stiff nylon/polyester/Chinex blend for latex and chalk paint on rough surfaces like drywall, brick and siding. Buy the natural bristle for fine oil work and the synthetic for water-based production work.

• Choose the White Bristle Sprig if you are applying oil-based stain, polyurethane or clear finish and want a smooth, brush-mark-free result.
• Choose the Pro Extra Glide if you are painting with latex or chalk paint and want a stiff brush that holds a lot of paint on rough surfaces.
