Glass-Block walls are a popular design choice both indoors and outdoors. A Glass-Block wall makes a beautiful patio privacy wall while not leaving you with the feeling of being closed in. Glass black walls are a perfect choice for shower enclosure privacy rather than glass shower doors or shower curtains. They also function beautifully as a partial or full room divider. Part of the appeal of Glass-Block walls is their ability to let natural light filter through and into your room. Traditional walls and half walls block light and tend to give the living space a smaller closed in feeling. Glass-Blocks are available in specific sizes so your wall needs to be planned based on the sizes that are available because Glass-Blocks are not made to be cut or trimmed. Glass-Blocks come in many shapes and colors to fit your design ideas.
Measure the length and height of the area you want your Glass-Block-wall. Multiply the length times the height and divide that number by the measurement of the glass bricks. This equation will let you know how many Glass-Blocks you will need. If you do not have a whole number, re-work the size of the wall because like mentioned above you will not have the opportunity to cut the Glass-Blocks to make them fit. Measure the height and the length of the wall and divide that number by the size of the edging or finish blocks to figure out how many end Glass-Blocks you will need. The Glass-Blocks that end the wall at the top or the end have finished sides.
Use masking tape or painters tape to draw 2 parallel lines on the floor. The lines should be about a 1/4 of an inch wider than the width of the brick. These will be used as guidelines.
Lay down your Glass-Block track in between your tape guidelines. The Glass-Block track is a piece of metal that is screwed into the floor and the first row or course of Glass-Blocks fits into it. Using this track ensures a straighter line or a perfectly curved-wall.
Screw the track into the floor.
Mix mortar in a bucket according to the directions on the bag.
If you are butting the glass wall up to an existing wall, place bracket into the track and screw the bracket into the wall. You will have to do this for each course to give extra stability to your wall.
Apply about 1/2 an inch of the mortar into the track. Work in about 3 foot sections so the mortar does not dry out before you get to it.
Use a trowel and put about 1/4 to 1/2 of an inch of mortar on the base of the Glass-Block and up the side that will face an existing.
Place the first brick up tightly against the existing wall if you have one. If you aren't building off of an existing wall, start with a end block.
Place a level on the Glass-Block to check to make sure it is level. If the block is not level, use your hand to tap it down.
Put a spacer in next to Glass-Block. Spacers keep even spaces between the blocks.
Put about 1/4 of an inch of mortar on the side of the next brick, place it tightly up to the spacer. Continue on down the line to make the first row or course. When you get to the end of the wall put in an end block.
Continue to use a level on each Glass-Block as you install it to make sure your wall remains level.
Use a piece of metal reinforcement. Lay it on top of the first course of blocks. The metal reinforcement does just what it sounds like it does, it reinforces the bond between courses.
Lay the Glass-Block on the second course exactly as you did on the first course. Continue to build the wall upwards in the same manner.
Use top blocks to top off the wall.
Wipe away excess mortar with a damp sponge as you go along.
Make sure the wall is not used or leaned on for 48 hours.
