What type of mortar should I use when installing a walk in glass block shower? What type of mortar should I use when installing a walk in glass block shower?
You need glass block mortar when working on walk in glass block shower. This white adhesive cement, with fine texture, sets the glass blocks in place. Although glass block mortar uses Portland cement as base, it does not have pebbles in it. This quality of glass block mortar makes it a better bonding cement for glass blocks than the other types of mortars. It adheres to the surface of the glass blocks firmly, is crack-resistant, and is water proof. If you use other types of mortars, expect cracks and weathering to occur sooner, due to exposure to moisture in the shower.
