Siroflex Instant Plaster Filler

Siroflex Instant Plaster Filler is a ready‑mixed, ultra‑lightweight plaster filler designed for quick and effortless repairs to interior walls and ceilings. Its non‑shrinking formula fills cracks, joints and screw holes with ease and dries rapidly, allowing overpainting with emulsion or synthetic paints within about 10–20 minutes under normal conditions. Once cured, the filler can be sanded smooth to blend seamlessly with surrounding surfaces, and its formulation is non‑corrosive towards metals, making it suitable for use on plasterboard, concrete, brickwork and traditional plaster.
