Use metal anchors at the top, too Photo These anchors are the only solid connections you make to the ceiling and wall.
The soft, plastic expansion strip Figs. Rather, use silicone caulk to fill the crack where the block meets the wall, both inside and outside the shower. Also glue tile to the top plate Fig. Finally, to make cleaning easier, seal the mortar joints on the inside after giving them about a week to dry.
You can use the same sealer you used for the tile grout available from tile dealers. Step-by-step process Outline the shower design on the walls and floor, remove the wall covering, and fit the shower base to locate the drain.
Trial fit blocks to check measurements. Double the floor joists under glass block wall when plumbing the drain lines. Add 2x support blocks where glass block wall parallels the joists. Insert two straight studs into the wall, make them perfectly vertical with a level, and nail them to the top and bottom plates. Build a form painted yellow and red here to mold the concrete sill around the base. Make the top even with the base top and level. Lift the shower base and spread a thick asphalt layer over the top of the dried concrete sill.
Then reset the shower base. Stack the blocks using shims and spacers to check their fit. The plate should be positioned directly above the concrete sill below. Lay a mortar bed on the sill, and set the first row of blocks. Begin with the corner and use spacers and shims to level the first row. Let set two hours. Mix more mortar and fill the first row joints, using a piece of wire reinforcement to make sure the joints completely fill. Spread another bed of mortar over the first row and lay wire reinforcement into it.
Repeat every other row. The spacers remain in place. Butter the side of each set block and press the next block against it so mortar squeezes out and it fits tightly against the plastic spacers. Set the corner block last.
Adjust the entire row to fit the corner correctly, it necessary. Fasten a steel anchor to the studs with two screws before adding the third row. Mortar hides the anchor. Repeat every other raw. Tap blocks with a trowel handle to adjust them. Use a straight edge that reaches from the concrete sill to the top plate to keep them plumb.
Fill the concave sides of blocks along edges so the mortar color shows through the block. Attach anchors between every other block in top row. Pack mortar in joints when it stiffens but before it hardens with a concave striking tool. Break off spacer ends and smooth the joints.
Brush off remaining lumps of mortar, then buff block faces with a dry towel. Scrub off stubborn residue with an abrasive pad. Caulk the gaps at the top and sides with silicone caulk, after gluing tile to top plate.
Then calculate the area of the space. In this case, measure the height and length that you want the wall to be and mark these spots on the floor and wall. If you're installing these blocks on a wall to make a window, make sure the wall can support the weight first.
These blocks are much heavier than a normal window, so the wall needs to be strong enough. Ask a contractor to assess your wall strength if you aren't sure. Calculate how many blocks you need for the project. After taking your measurements, figure out how many materials you need for the project.
The average glass block is 8 in 20 cm by 8 in 20 cm by 4 in 10 cm. Since glass blocks can only be installed 1-across, calculate the area of each block to get 64 sq in cm 2. Then divide 64 into the area measurement you took of the installation area.
The area of the blocks may not evenly divide into the work area. If you received a calculation of Buy the correct number of glass blocks and an installation kit.
After calculating how many blocks you need for the job, purchase that amount. Also get an installation kit that comes with the correct mortar or glue, spacers for the blocks, and landing strips. These kits are available at hardware stores or online. Speak with a store employee and tell them what job you're planning. Use their advice to pick the correct installation kit. If you can't find complete installation kits, most of the materials are available separately.
Get mortar designed for glass blocks, spacers, and PVC base strips along with the glass blocks. Cut PVC landing strips to the length and height of your glass block wall.
Glass block installation kits come with PVC bases to rest the blocks in. Take one and measure it to the length of the wall, then cut it. Do the same with a PVC strip for the height of the glass block wall. If the blocks are free-standing, then cut 2, 1 for the base and 1 for the height.
Then screw it down to it provides a stable base. Snap along these lines if your kits are designed this way. Screw the support strips to the wall and floor. Lay out the base strip where you want to start the block installation. Then drill screws through the marked spots on the strip. Repeat the process for the wall supports. Some installation kits have screw plugs that go into the floor and wall before you drill the screws.
Always follow the instructions provided on your installation kit. Method 2. Mix the mortar to bond the blocks together. Your installation kit may come with a bonding material. Otherwise, buy a mortar designed for use with glass blocks from a hardware store.
Measure out the amount of water that the mortar instructs you to use and pour it into a bucket. Then add the mortar and mix it with a shovel in a circular motion. Mix for minutes, until the mortar becomes a thick paste. You may need to buy more than 1 pack, depending on the size of the job.
If you have an electric mixer, this will make the job much faster. For some installations, like a shower, professionals recommend using caulk instead of mortar. Scoop some mortar with a trowel and spread it on the floor and wall of the corner. Place a corner spacer into the mortar. Installation kits come with spacers to place between the blocks.
Take a corner spacer and press it into the mortar at the corner. Make sure it touches the floor and wall directly, rather than floating on the mortar. Press the first block into the corner. Start by rubbing a thin layer of mortar on the side and bottom edges of the block that will contact the mortar. Then press it down into the corner so it rests on top of the spacer. Place 2 spacers 8 inches 20 cm apart from the first block.
These spacers go in between each block and remain there permanently encased in the mortar. Take the first one and press it into the corner of the first block. Then lay a second one 8 inches 20 cm away. If the spacers still show after you press the blocks together, touch up the area with a bit more mortar to cover them.
Alternatively, you could seal the mortar with caulk when it's cured. This will cover any spacers or other imperfections. Spread mortar between the 2 spacers. Then spread mortar onto the side of the first block. Press the second block into position. Spread mortar on the side and bottom edges of the block. Then press it down between the 2 spacers. Push it against the first block so the mortar binds them together. Shaomei Westerhoven Reviewer.
