Install a glass block wall by measuring the area for the wall and using eight-inch blocks. Arrange the blocks on a table or on the floor before beginning and make the frame to fit. Install the frame and attach the glass using glass-block mortar.
Installing a glass block wall adds light to an otherwise dark room. Follow the instructions below to complete the work on an existing opening.
- Measure the opening
- Arrange the blocks using spacers
- Assemble the frame
- Attach the frame
- Mix the glass-block mortar
- Attach the metal retaining strips
- Attach the reinforcing strip to the mortar
- Finish laying the blocks
- Clean up the mortar
- Use caulk
- Install molding
Measure the opening and calculate how many eight-inch blocks it takes to fill the space.
Arrange the blocks on a table using spacers. Make a frame with one-inch by six-inch boards to enclose the blocks.
Assemble the frame using nails or wood screws.
Making sure the frame is level, attach the frame to the opening.
Mix the mortar according to the directions on the package. Spread it on the bottoms and edges of the glass blocks and squeeze it into the corners using the spacers. Continue this from left to right until the first row is complete.
Screw the metal retaining strips onto the side frame. Bend them into place to fit between each row of blocks.
Apply more mortar to the first row of glass blocks. Push the reinforcing strip to the mortar until it is no longer visible.
Lay the next rows of glass blocks, adding mortar and reinforcing strips where required, and keep going up to the top.
After allowing the mortar to set for a few minutes, use a sponge and warm water to clean it off of the glass blocks.
After the mortar hardens, use a bead of caulk around the perimeter of the block wall.
Install molding to cover the gap between the frame and the wall. Fill and paint as desired.
