Introduction
MDF boards (Medium-density fibreboard) are a popular material used in furniture and other woodwork projects. It can be an affordable alternative to solid wood, but it is not resistant to water damage. When MDF boards come into contact with water, they can swell, warp, and even disintegrate, ruining your project. Fortunately, in this DIY guide, we will show you how to repair MDF boards damaged by water.
