Gurit Glass Bubbles are hollow glass spheres that serve as a versatile white filler, ideal for waterproof filling and bonding applications. These bubbles are harder and more difficult to sand compared to microballoons, making them perfect for creating a durable hard surface finish, suitable for hard-wearing edges and surfaces. With excellent waterproof properties, they are particularly useful for below-waterline applications on boats. Gurit Glass Bubbles offer an economical solution for general filling needs and low-strength bonding of softwoods. While they are harder to sand, they can be blended with microballoons for custom color adjustments, providing a flexible approach to different filling tasks.
