Merit Pro brushes are designed for smooth, even application of a range of coatings including varnishes, stains, polyurethanes, and latex paints. They are constructed with filament types suited to specific finish chemistries — synthetic bristles for water-based products and natural bristle for oil-based finishes — which helps achieve a finer, more controlled film application on wood surfaces.

Synthetic-bristle brushes are the correct choice for water-based polyurethane and other water-borne finishes because natural bristles absorb water and become limp and uncontrollable when wet. Nylon or polyester filaments maintain their shape and spring in water-based products, resulting in a more consistent film. Use natural bristle for oil-based varnishes, polyurethanes, and paints where solvent resistance is needed.

Clean oil-based finish from brushes with the appropriate solvent (mineral spirits for oil-based finishes, water for water-based finishes) immediately after use, working the solvent through the bristles thoroughly before rinsing. Reshape the bristles and store the brush in its original packaging or a brush sleeve to maintain the shape. Never let finish cure in a brush, as it will permanently damage the bristles. The Merit Pro 4-piece brush set includes sizes suited to a variety of woodworking applications.

A 3- or 4-inch wide flat brush is generally ideal for large flat panels because it covers more surface per stroke and reduces lap marks from excessive brush passes. Narrower brushes (1 to 2 inches) are better suited to edges, mouldings, and detail work. Using the largest brush you can control comfortably for a given surface helps produce a more even finish.

Yes — many Merit Pro brushes work well for applying stains, conditioners, and topcoats alike. For gel stains and wiping stains, a foam brush or lint-free cloth can also be effective, but a quality bristle brush gives you more control over the quantity of stain applied and how it is worked into the grain. Wipe off excess stain before it dries per the product instructions.
