 INSTALLATION

Preparation

Clean all surfaces that will be in contact with mortar.  Surfaces must be free of dust, dirt, oil, grease and any contaminates. 

Mixing

Place water (or LATICRETE® 333 Super Flexible Additive*) in clean mixing pail.  Add LATICRETE 8500 Glass Block Mortar and mix by hand or with a low speed (150 rpm) drill to a stiff, non-slump consistency.  Approximately 4 quarts (3.8 ℓ) of liquid mixes with 50 lbs. (22.7 kg) of powder.  Allow to slake 5–10 minutes.  Remix and apply as normal mortar.

Note:    For interior applications, mix with water.  For prefabricated panels, exterior applications and for improved adhesion, mix with LATICRETE 333 Super Flexible Additive. 

Application

Place a full bed of mortar on the base or sill.  Do not furrow.  Set first course of glass blocks and tap into place with a rubber mallet.  Apply full bed of mortar to head joints on each block as they are placed.  

Set each course of glass block in a full mortar bed.  Rake or tool joints to a uniform appearance when mortar is firm.  Follow manufacturer’s instructions regarding anchors, spacers, expansion joints, reinforcements and wall ties.

Cleaning

Remove all excess mortar from surface of glass blocks using a damp sponge or cheese cloth before  mortar hardens.  Clean tools with water while mortar is wet.
