What if some mortar gets into the design during installation? Will that ruin the glass blocks?
Not to worry! It’s not uncommon for some mortar to get into the texture of the glass design during installation, and is easily removed during the mortaring process. Sometimes a small amount of mortar, or a haze may be left behind after the mortar is cleaned up. Generally, all that’s needed is a little white vinegar to clean it out if any is left behind after the installation.
