Buying Guide
Choosing the right brush can feel overwhelming. Here’s what to consider before you buy.
Brush Type: Consider the type of polyurethane you’re using. Oil-based needs natural bristles. Water-based works best with synthetic brushes or foam.
Bristle Quality: Look for bristles that are firmly attached. Shedding bristles can ruin your finish. A good quality brush will last longer.
Brush Size: Choose a brush size appropriate for your project. Smaller brushes are better for detail work. Larger brushes are good for covering large areas.
Handle Comfort: A comfortable handle will make the job easier. Especially if you’re working on a large project.
Cleaning: Consider how easy the brush is to clean. Proper cleaning will extend the life of your brush.
Price: Balance price with quality. A more expensive brush may be worth it if it provides a better finish and lasts longer.
Synthetic vs. Natural Bristles: Synthetic brushes are best for water-based poly. Natural bristles are better for oil-based poly.
Brush Shape: Angled brushes are great for corners and edges. Flat brushes are good for covering large, flat surfaces.
