Can I use the same brush for water-based and oil-based paints?
Using the same brush for water-based (latex) and oil-based paints is not recommended due to the differing cleaning requirements and bristle compatibility.
Water-based paints work best with synthetic brushes, which resist water absorption and clean easily with soap and water.
Oil-based paints require natural bristle brushes, which hold solvents better but can swell and lose shape if used with water-based paints.
Cleaning a brush used for oil-based paint involves solvents like mineral spirits, and residual solvent can contaminate water-based paint, causing clumping or poor adhesion.
If you must use the same brush, clean it thoroughly between uses, rinse oil-based paint with mineral spirits, then wash with soap and water, and ensure it’s completely dry before switching to water-based paint.
What’s the difference between angled and flat paintbrushes?
Angled and flat paintbrushes serve distinct purposes in painting, defined by their shape and application.
Angled brushes, also called sash brushes, have bristles cut at an angle, typically 1.5–2.5 inches wide, making them ideal for precision work like cutting in around edges, corners, and trim.
The angle allows better control in tight spaces, such as where walls meet ceilings, ensuring clean lines. They’re also great for detailed work like painting furniture or cabinets.
Flat brushes, with bristles cut straight across, usually 3–4 inches wide, are designed for covering larger, flat surfaces like walls, doors, or panels.
They hold more paint and spread it evenly over broad areas, making them efficient for base coats or filling in after cutting in.
For a 12x12 room, a flat brush can speed up cutting-in by 10–15 minutes compared to an angled brush on straight sections.
Both types benefit from Paintbrush Guard, which keeps bristles wet during breaks, saving 15–30 minutes per session and ensuring consistent performance across tasks.
