This 180-grit sanding sponge is perfect for surfaces with imperfections or to refine the work done with the 100-grit. The flexibility of the material easily conforms to any shape including rounded surfaces or hard-to-reach recesses. It’s also highly useful for removing traces of glue or putty when filling gaps. It can be used both dry and moistened with water. We recommend cutting a piece of the size required for the job in order to avoid waste. The backside has the grit size printed over the entire surface so that once a piece has been cut, it is still easily identifiable. Ideal for use in combination with different grit sizes.
