There are paint brushes made for oil based products and brushes for water-based products. Brushes come in a variety sizes, shapes, handle types and of course, different qualities. Choosing the right brush will make your work easier, faster and better.
Bristle Type
Natural bristles typically are made with animal hair. Chinese bristle is usually made with hog's hair or ox hair. They are best for oil based paints, varnishes, shellacs, and other finishes. Natural bristles should never be used with water based (latex) paints. The water is absorbed by the natural bristle and causes the brush to swell up. Natural bristles develop splits in the tip (flagging) which results in smoother application of the paint and thus fewer brush strokes.
Synthetic bristles include nylon, polyester and nylon/polyester blend. A synthetic bristle is the proper choice for water based (latex) paints. Nylon and nylon/poly blend brushes can be used for oil or water based paints, but a polyester brush is best suited only for latex paints.
This is how paintbrushes are made.Watch full episodes of the Science Channel series 'How It's Made' on the Science GO app or sciencechannel.com.The INSIDER t. A chiseled brush permits the painter to cut into tighter corners and paint more precisely. Brush handles may be made of wood or plastic while ferrules are metal (usually nickel -plated steel). Purdy's brushes are hand-made without compromise, in the same way they were over 85 years ago. Each Purdy brush is 'signed' by the person who made it. This is done by a personalized sticker with the brushmakers signature. This is a mark of pride in a job well done. What is the Difference Between Paint Brushes? T here are paint brushes made for oil based products and brushes for water-based products. Brushes come in a variety sizes, shapes, handle types and of course, different qualities. Choosing the right brush will make your work easier, faster and better.
Foam brushes can be used for oil or water based paints. They work best with thin products, like stain and polyurethane finishes. They wear out quickly and are best used as throw away task brushes. Extended use of a foam brush can result in bits of the foam breaking off and sticking to the finish.
Brush Size
Choose a brush that matches the size of what you are painting. Wide brushes hold a lot of paint and cover more area and so are the best choice for painting walls. A small brush (1 to 2 inches) should always be used for painting narrow trim and small surfaces. Don't turn a wide brush sideways to use the narrow edge, that will damage the brush.
Brush Task
Brush size is a factor in the selection of the right brush, but the cut and tips of the bristles are also a factor. A sash brush is sized for fine work on window sashes and trim. An angled sash brush cuts the bristles across the width at an angle, allowing more control in delicate, close-in work.
The tips of some brushes are beveled across the thickness of the brush. The bevel allows more control for 'cutting-in' paint; for example, cutting-in the line between a wall and the ceiling.
Brush Quality
The quality of a brush is reflected in the price. A quality brush has more bristles, properly sized-sized spacers between the bristles, a rust-resistant ferrule to secure the bristles and uses top-quality bristles. A quality brush will hold more paint, will provide smoother, brush mark free results and, with care, will last a lifetime.
Cheap brushes will rust, lose bristles and typically have a large spacer that reduces the number of bristles. Fewer and low quality bristles means more dipping into the paint can and more work in trying to get a smooth, brush-mark free finish.
Handle Type
Handles come in bare wood, plastic or lacquered wood. Most professional painters choose an unfinished wood handle because they are easy to hold and are more comfortable.
Handle shapes also vary. Beaver-tail handles bulge in the middle, helping you grip it in your palm. Rat-tail handles are long and straight making them easier to hold for fine detail work. Many other shapes are available and your selection should be made based upon comfort.
As you likely know, paint brushes come in what seems like an unlimited variety of shapes and sizes, bristle types and price. Knowing the difference between natural and synthetic bristle paint brushes will help you figure out what to choose for your next DIY project.
Natural
As the name suggests, natural bristle paint brushes are made from natural animal hair such as hog, sable and badger.
When to Use Natural Bristle Brushes
Natural bristle brushes are great when you are using:
- Oil-based paint
- Varnish
- Shellac
- Shellac-based primer
- Alkyd enamels
- Stain
- Polyurethane
- Chalk-based paint
- Milk paint
- Clay-based paint
The Good
These type of bristles actually split naturally which makes them designed to pick up, hold and distribute natural paints and can speed up painting. The soft flexibility of natural bristle brushes help to apply a thin, even layer of paint reducing streaks and distributes paint evenly. When using these brushes with natural paints (chalk/milk/clay-based) there is less chance of streaking than with synthetic brushes.
The Bad
If you are looking for precision painting, natural brushes can be difficult to use.
Natural bristle brushes also shed the first few times you use them. If you have bought a quality natural brush, the bristles should stop shedding after the second or third use.
Synthetic
Synthetic bristles are made from materials like nylon, polyester or a mix of both.
When to Use Synthetic Bristle Brushes
Synthetic bristle brushes are great when you are using:
- Water-based latex paints
- Water-based primers
- Gloss Paint
- Acrylic paint
- Water-based wood finishes
The Good
Nylon brushes are durable, excellent paint pickup, and smooth finish.
Polyester brushes maintain their shape and control which is great for detail work.
Nylon/Polyester blend brushes combine all the positive qualities and is the most popular choice.
The smooth texture and springiness of the bristles make for an even finish aand great for woodwork and furniture in water based satin,eggshell and gloss finishes.
Modern synthetic brushes are excellent and have the advantage of being cheaper than natural hair.
The Bad
Nylon brushes soften in hot weather or after a lot of use with latex paint. Brushes can lose the ability to create a smooth, precise finish.
Polyester brushes have a lower paint pick up which means you will need to reload your brush more often.
Paint with fast-drying ingredients (majority on the market right now) will stick to polyester making them harder to clean. If you look after these brushes, they’ll last for years.
What happens if you use the “wrong” bristled brush with the recommended paint?

If you try to apply latex paint with a natural-bristle brush, the bristles will absorb the water from the paint and become extremely limp, making it difficult to spread the paint smoothly.
If you try to apply chalk/clay-based paint etc. with a synthetic brush, you will likely have a lot of brushmarks and have a lot of extra work getting a smooth finish.
Not sure what size of brush to use either?
The size of the brush to use will really depend on the type of project you are tackling. Here is a short guide to help you get started. Don’t forget to read the packaging on each brush. Many manufacturers list the recommended use for their brushes.
4″ – 6″ This size would be great for painting large flat areas. I have one this size but have yet to use it!
2″ – 3″ The size I use the most! Great size for painting all types of smaller flat surfaces.
1″ – 1.5″ Perfect for more detailed smaller projects. Great for trim work on doors & walls too.
0.5” I have a ton of these small brushes for all my “crafty” projects.
Shapes
The shape of the brush can affect how easily you will be able to paint your project. A brush with a squared-off end works well for flat surfaces because it will hold plenty of paint and spread evenly. Angled brushes are for precise work on trim and corners because they allow for more control and a straighter line.

Do your really get what you pay for with a paintbrush?
Paint Brush Made Up Of
As a general rule, you do get what you pay for with paintbrushes. Although I have a lot of inexpensive brushes in my workshop, I have found that I keep going back to the more expensive brush. I am currently using a Cling-On brush, which I paid $30 CND, and LOVE it because of the smooth finish I achieve.
Quality brands to check out:
- Cling-On! – synthetic bristle brushes
- Zibra – synthetic bristle brushes
- Purdy – offers both synthetic and natural bristle brushes
