For applying thick finishes, which brush is preferred?

• A. China Bristle Brush
• B. Nylon Brush
• C. Synthetic Brush
• D. Natural Hair Brush

Answer: (A)

Thick finishes need a brush that can carry and lay down a heavy coating without the fibers bending or losing shape. A China bristle brush is made from hog bristle, which is naturally stiff, durable, and springy. That stiffness helps push a viscous finish onto the surface and distribute it evenly, giving a smooth film with fewer brush marks. The natural fibers also hold and release the oil-based finish well, which is ideal for varnishes and enamels that are thicker than latex paints. In contrast, nylon and other synthetic brushes are softer and better suited to thinner, waterborne coatings, while natural hair brushes can work for oils but may not hold up as well under very thick coatings.
