Based on high-strength, lightweight polymeric fillers, this product outperforms conventional fillers in most applications. It's designed for both professional and DIY use. The filler is easy to apply and doesn't require sanding, finishing to a smooth surface. It dries quickly, ready to paint or paper in approximately 30 minutes. It fills up to 75mm deep in one application and doesn't sag or shrink. The product is overpaintable with most solvent-based and emulsion paints, and overstainable.
