What size brush should I use for cutting in?

A 2-1/2 inch angled sash brush is the most versatile for cutting in along ceilings, corners, and trim. Use a 1-inch brush for window muntins and detailed work.

How do I clean paint brushes properly?

For latex paint, rinse under warm running water while flexing bristles until water runs clear. Use a brush comb to remove paint from the base. Shape bristles and hang to dry.

Code Requirements

No specific code requirements. Use appropriate bristle type for paint base (nylon-polyester for latex, natural bristle for oil-based). Dispose of cleaning solvents per local regulations.

Buying Tips

Invest in one quality 2-1/2 inch angled brush rather than a cheap set. Clean brushes immediately after use. Never let paint dry in a brush. Use nylon-polyester for latex paint and natural bristle (china bristle) for oil-based.
