In construction projects, selecting the right formwork makes the stripping process significantly easier. With a wide variety of wooden formwork available on the market, how can you identify high-quality panels that are durable and offer excellent surface flatness? Keep these three points in mind:
1.Check the surface film and flatness:High-quality red or black film-faced plywood features a uniform film coating that provides excellent water and corrosion resistance. Inspect the panel surface for any obvious bumps, overlaps, or delamination; these factors determine the smoothness of the concrete finish after pouring.
2.Check the core veneer bonding strength:Premium formwork utilizes full-piece core veneers that are stacked and glued layer by layer. If internal voids exist, the formwork is highly susceptible to bulging or fracturing during repeated use or high-pressure concrete pouring.
3.Check the edge sealing:Proper application of waterproof edge paint effectively prevents moisture from penetrating the core, thereby stopping the formwork from warping or cracking due to water absorption and swelling.
