How to Remove Glass Block Grout

Glass blocks provide a lot of support to a wall while still allowing light to flow through the wall. Glass blocks are held together by grout, which hardens like cement. When you are taking down a glass block you will have to remove the hard grout between the blocks. Use care to ensure that you don't break the glass blocks.

Things You'll Need

  • Drop cloths

  • Gloves

  • Goggles

  • Cold chisel

  • Hammer

Step 1

Move furniture away from the glass block wall or window. Place drop cloths over the carpet and furniture you are unable to remove. Removing grout mortar is a messy job that will cover the room in a layer of dust.

Step 2

Put on gloves and goggles to protect your eyes and skin.

Step 3

Position the cold chisel on the layer of mortar between the glass blocks. If you are dismantling an entire glass block wall, begin with a glass block on a top corner of the wall.

Step 4

Tap the end of the chisel with a hammer several times. This will dislodge the mortar. Repeat all of the way around the glass block to remove it.

Step 5

Repeat with all of the other glass blocks.
