Create the perfect repair putty with Q-Cel Lightweight Microsphere Filler. Proudly made in the USA, Q-Cel is the industry’s highest-quality brand of hollow glass microspheres, designed to thicken resin without adding significant weight to your surfboard.

Whether you are working with Polyester or Epoxy resins, Q-Cel is the filler of choice for structural ding repairs and filling voids in foam. When mixed at varying ratios, it transforms liquid resin into a creamy, white, lightweight paste that is exceptionally easy to sand once cured.

Key Features:

Ultra-Lightweight: Thickens resin while maintaining the buoyancy of your board.

Universal Compatibility: 100% safe and effective for use with both Epoxy and Polyester resins.

Easy Sanding: Formulated to sand smoothly without the brittleness of other fillers.

White Finish: Naturally blends with white surfboard foam for a cleaner looking repair.

Pro Tip: For large foam fills, mix Q-Cel until you reach a "peanut butter" consistency. This ensures the putty stays in the hole and doesn't sag or run while curing.
