URE-FIL™ fillers are designed to be mixed with urethane resins to modify their working properties, weight, texture, and appearance.
When blended into urethane resin, they help control shrinkage and can influence the final surface finish, ranging from smooth to textured or stone-like effects. Different versions offer unique performance benefits, allowing customization for projects like casting props, producing rigid parts, or achieving realistic material effects.

Create a realistic wood grain effect with this filler.
Mix 1 part filler with 1A:1B of Smooth-Cast™ 325 resin.
Ensure your mold has the desired wood grain pattern.
Apply wood stain or shoe polish after demolding.
Thoroughly disperse filler for uniform consistency.
Use 'double-mix and pour' for better results.
Enhance your resin projects with improved stability and unique effects.
