How to Choose the Right Brush
Angled Paintbrush & Flat Paintbrush:
Two Main Paintbrush Options
Angled sash paintbrushes
-
Offer bristles cut at an angle.
-
They are best for corners, woodwork, molding or other surfaces that demand detail work.
Flat sash paintbrushes
-
Provide bristles cut straight across the end.
-
They are best for larger, flat surfaces where there is less detail to paint.
Paintbrush Quality
-
A quality paintbrush lasts longer
-
Holds more paint and applies paint more evenly.
-
A better-quality paintbrush won't leave brush marks or shed bristles.
-
A good brush flexes at the tips and springs back into shape when pressure is released.
-
When the bristles are pulled apart, a quality brush won’t have a gap in the centre, exposing the handle.
Paintbrush Sizes
Larger brushes hold more paint than small brushes do, cover more surface area, and cut a wider line.
-
4 to 6” wide, flat sash paintbrush for wide-open flat surfaces like long, uninterrupted walls and garage doors.
-
3 to 4” wide, flat sash paintbrush for large flat surfaces like walls, doors, and bookshelves.
-
2 ½” flat sash brush will work for narrower flat surfaces like wide moulding, cabinet doors, or baseboards.
Smaller brushes give you greater control.
-
2” wide-angle sash brush for cutting in corners.
-
1 to 2 ½” angle sash brush to paint woodwork and molding as well as projects where precision matters, like the details of carvings or trim work.
Paintbrush Bristles:
While paintbrush bristles can have either synthetic or natural bristles, synthetic bristles are the most practical. Commonly used by DIY-ers and professional painters alike, they work well with water-based paints.
Bristle options include:
-
Polyester SRT: Recommended for latex paints, acrylic paints, and oil-based enamels, these bristles offer exceptional paint capacity and provide the fastest results.
-
Polyester Microfilaments: Use this type of bristle for all paints, especially semi-gloss and satin or pearl finishes. They provide extra flex for smooth application, leave few brush marks, and have excellent paint capacity.
-
Firm Polyester: Good for all paints, especially thick or heavy coatings, these bristles provide a sharp edge for controlled painting, even in hot or humid conditions. Exceptional paint capacity gives you fast results.
-
100% Polyester: Good for all paints, especially lighter or thinner coatings, 100% polyester bristles virtually eliminate brush marks. They also provide superior smoothness and robust paint capacity.
-
White bristles are the best choice for oil-based or alkyd paints.
