Can Glass Blocks or Glass tiles be polished?
• ANSWER: Glass blocks that are used for wall construction are not a good scratch removal application. Many of these glass blocks are not completely smooth on the surface which would make polishing difficult. Glass blocks and glass tiles also tend to be tempered from their production mold formation. The other problem with attempting to polish a glass block wall or glass tiles is the surface area of the glass is quite small between the grout areas. If the polishing disk is allowed to come in contact with the grout material, small amounts of this material may be broken off and contaminate the polishing process causing new scratch damage. The grout material may also damage the polishing disk. Furthermore, if the polishing compound gets onto the grout material, it can stain it. If you have a glass block wall or glass tile surface that is scratch damaged, you may be better off replacing the damaged items rather than attempting to polish them.
