Tetrion Hard as Rock Filler 330g is a tough, ready-mixed filler designed for durable interior and exterior repairs.

Its high-strength polymer-reinforced formula is suitable for masonry, stone, concrete, cement, plaster, wood and pebble-dash, making it ideal for repairing cracks, holes, damaged steps, walls and garden structures.

Ready to use straight from the tube, it requires no mixing or measuring. It fills depths of up to 10mm in one application and can be built up in layers for deeper repairs.

Once hardened, it creates a strong, crack- and shrink-resistant finish that can accept screws and bolts. It can be sanded after approximately 2 hours and overpainted after around 24 hours, becoming weatherproof once suitably painted.
