What kind of brush is typically used in the application of resin?

In the application of resin, a stiff brush is typically used because it allows for the effective spreading and manipulation of the viscous material without damaging the surface being worked on. The rigidity of the bristles helps to evenly distribute the resin, ensuring that it thoroughly covers the area and penetrates well into any texture or pattern present. This can be particularly important when working with composite materials or in detailed areas where even application is crucial for structural integrity.

Using a stiff brush also helps to avoid excessive build-up of resin in any one area, which can occur with softer brushes that may not have the necessary pressure to spread the resin evenly. By selecting a stiff brush for resin application, technicians can achieve a better finish and ensure optimal adhesion qualities, which are vital for the durability and performance of the final product.
