How to Use Cement in a Grout Bag

A grout bag is a plastic or canvas bag with a narrow tip at one end that you fill with grout and squeeze to expel it into the spaces between tiles. It's the same concept as that of a pastry bag. A grout bag is normally used to grout tiles when you don't want to use the more common approach of wiping the grout over the whole tile surface, such as when the tiles are unsealed and will stain from the grout, for example. You can use the same concept to apply cement between bricks, on stonework or for outdoor tiles.

Instructions

- 1
  Combine your cement mix with water in a bucket, in the ratio specified on the cement packaging, to make a total volume of approximately 1/2 gallon. Thoroughly mix the cement with your drill and mixing bar.
- 2
  Pour the cement into the open back end of your grout bag, using a wooden spoon to guide it in. Put in as much cement as will fit. Close the bag.
- 3
  Place the tip of the grout bag onto the first joint between the tiles or bricks. Squeeze the bag with both hands until grout comes out of the tip.
- 4
  Drag the bag slowly back along the line while continuing to squeeze the bag so it fills the line with grout. Keep the grout in the space. Avoid getting it on the face of the brick or tile.
- 5
  Repeat for each of the other lines.
- 6
  Let the cement set for about 30 minutes. Scrape the rounded edge of a wooden spoon along the length of the line to get the surface of the cement consistent and slightly below the surface of the brick or tile.
- 7
  Let the cement dry for 12 hours. Brush it vigorously with a stiff broom, taking off any residual sand.
