URE-FIL Fillers

URE-FIL® fillers disperse easily in Smooth-On materials. They can be added to materials in different proportions to achieve a variety of working properties and effects. Some fillers are designed for cost-savings, others are designed for specific casting effects or improved physical properties. Other URE-FIL® fillers are designed specifically for thickening materials for brush-on or trowelable application.
