Using metal as a mosaic base

When using metal as a mosaic base, for example when building mosaic garden tables, frames or garden sculptures, make sure you toughen up the often glossy surface with steel wool and examine the base closely for rust.

If you find patches of rust, treat them before you create your mosaic! Many times rust can have only a small effect on a mosaic however you don't want to spend hours creating a masterpiece only to find in a year's time that the base is no longer structurally sound!
