Instructions / Assembly

Do not grout the perimeter joints between the blocks and the wall and curb. These joints must be caulked after the grout has dried for a pliable watertight joint.
Drag grout float across surface at a 45-degree angle to pick up excess grout.
IMPORTANT: Use the margin trowel to thoroughly pack the grout in the joints of the EndBlock Finish Units. Apply all the mixed grout before begin the cleaning process.
3. FINISHING THE JOINTS
(Continued)
Begin application of grout: Starting at the top of the glass block wall, apply grout to the joints of glass blocks by moving the rubber float diagonally on a 45° angle
across the joints. This is the best application method to fill the joints with grout. Pack material into joints with float until full. Be carefully not to move glass blocks
while grouting since wall might still be flexible prior to grout cure.
