What Are Brushes For Water-Based Polyurethane?
Many people will use any old paint brush for water-based polyurethane, but the wrong type of brush can leave behind brush strokes that are easy to see in a shiny clear coat.
Brushes come in three different types, which are based on the material of their bristles. They are either made of natural animal fibers, synthetic materials, or foam.
Synthetic bristled brushes are the best for working with water-based polyurethane. This is because they are generally made from blends of nylon and polyester, which don’t absorb water as well as natural fibers do. Since they don’t absorb water as well, they are able to hold their shape better and deliver a more consistent brushstroke.
Natural fibers are best for oil-based products, but they are expensive and not ideal for water-based polyurethane.
Foam brushes work with both oil and water-based polyurethane, but they don’t deliver the quality that a bristled brush can. Typically, they are used in situations where speed and saving money are the priority.
What Are The Different Types of Brushes For Water-Based Polyurethane?
As far as synthetic brushes go, nylon, polyester, nylon/polyester, and Chinex/Tynex are the most common blends on the market. Each of which has its own strengths and weaknesses.
Nylon
Nylon brushes are known for being durable and have the ability to hold lots of polyurethane. The stiff bristles deliver a smooth finish time after time, as long as they don’t get hot. When used in a hot environment, the nylon can get soft, and the bristles can lose their strength and shape, similar to natural brushes when used with water-based polyurethane.
Polyester
Polyester brushes can hold up better in the heat when compared to nylon brushes. This makes them advantageous for exterior projects during the summer. Unfortunately, they don’t hold as much urethane as a nylon brush of the same size. They can be tougher to clean as well, which means they won’t last as long as nylon.
Nylon/Polyester
These are the best of both worlds. They combine the stiffness of polyester and the capacity to hold urethane of nylon brushes. That’s why DIY enthusiasts and professionals prefer to use them.
Chinex/Tynex
Chinex is a patented nylon blend that is a popular option on the market. It tends to be pricier than nylon and polyester, but it incorporates the strengths of synthetic and natural brushes. They hold lots of urethane, maintain their shape, are easy to clean, last a long time, and they have softer bristle tips like a natural hair brush.
How Do Brushes For Water-Based Polyurethane Work?
Brushes for water-based polyurethane have to be able to apply a beautiful clear coat without leaving behind brush strokes. That’s why synthetic brushes are the most popular. They hold their shape and stiffness much better than natural hair brushes, not to mention they are more affordable.
What Do You Look For In The Best Brushes For Water-Based Polyurethane?
When it comes to a great brush for water-based polyurethanes, durability and the amount of urethane it can hold are the most important characteristics.
Durability
Nobody wants to shell out money on a new brush every single time they have a new project, right? A top-tier brush needs to hold up to all-day use without falling apart or losing shape. A brush that loses its shape is next to impossible to make a straight and precise stroke with. They are liable to leave behind brush strokes as well.
Ability To Hold More Polyurethane
The more polyurethane that a brush can handle, the quicker you can get your job done. You will spend more time dipping your brush into your bucket and less time applying it with a brush that doesn’t hold much urethane.
Comfort
Brushes don’t weigh much, but they can get uncomfortable when you have to use one all day. Wooden handles tend to feel better in your hand for long periods of time as opposed to cheaper options like plastic. Take it from me, it’s always worth spending a couple of extra dollars instead of having hand cramps all day long.
Price
Brush cost will differ based on what the handle and the bristles are made of. Wood handles will be more expensive and comfortable than plastic. Brushes with full nylon or polyester bristles will be more affordable than synthetic blends like Chinex, but they don’t deliver as great of a finish.
