Household Bristle Paint Brushes

Use natural bristles (e.g., hog or blended) for oil-based paints and varnishes because they hold and release thicker coatings well; use synthetic nylon or polyester bristles for water-based (latex) paints because they resist swelling and maintain shape

For general tasks, keep a 1–2" angled sash brush for trim and windows, a 2.5–3" flat brush for doors and cabinets, and a 3–4" wide brush for walls or large flat surfaces; angling helps cutting-in while flats are efficient for coverage

Household bristle brushes vary by build and brand; budget options start under $20, mid-range around $20–$60, and higher-quality specialty brushes average higher, with aggregate category prices often in the tens of dollars

Look for a tightly packed, well-tapered bristle head, a rust-resistant ferrule (stainless steel or nickel-plated), and a comfortable, balanced handle—full-tang or securely crimped ferrules reduce bristle loss and extend brush life

For oil-based paints, clean brushes with the appropriate solvent (mineral spirits or brush cleaner), then wash with mild soap and water; for water-based paints, rinse thoroughly with water and soap. Reshape the bristles, let dry flat or hanging with bristles down, and store upright or flat to prevent bending

While a single brush can be used if thoroughly cleaned between uses, natural-bristle brushes perform poorly with water-based paints and synthetic bristles are preferred for water-based; dedicated brushes for each paint type give the best performance and longevity

Stiffer bristles provide better control and are suited to thicker coatings and textured surfaces; softer, finely tapered bristles deliver smoother finishes and are better for thin paints and careful cutting-in. Choose stiffness based on paint viscosity and desired finish
