The quality of concrete surface finish is directly influenced by the formwork system used. Plastic formwork provides a smooth and uniform surface due to its non-absorbent material and consistent panel structure. Unlike plywood, it does not warp, swell, or leave uneven marks. A common misconception is that all formwork produces similar results. In reality, material type plays a major role in the final appearance of concrete. Using high-quality plastic formwork can reduce the need for additional finishing work, saving both time and labor. In summary, choosing the right formwork system can significantly improve final project quality.
