High Gloss MDF is a type of Medium Density Fiberboard (MDF) that features a reflective, smooth, and shiny surface finish. The high gloss finish is typically achieved by applying a layer of high-gloss paint or lacquer, which is then cured under heat or with UV light to create a durable, mirror-like surface. This finish is popular in modern and contemporary interior designs, where sleek, clean aesthetics are desired.
