The easiest way to grout your Brickwebb project is with a grout bag and brick jointer. This method also reduces the amount of grout that gets on the brick face. Make sure that your brick adhesive and optional sealer has had at least 24 hours to dry before grouting.
We recommend trimming the end of your grout bag so that the opening is about 1/2” wide. To fill your grout bag, start by folding down the top edge of the bag and then step on the tip of the bag. Use a trowel to fill the bag about half-way
Unfold the top of the bag and hold it over your bucket of grout. Shake the back to remove bubbles and then twist until the grout starts to come out of the tip. The grout should come out when squeezed, but not be so runny that it drips out on its own.
Hold the grout bag with one hand in the middle and one hand at the end where it is twisted. Put the tip of the bag in the space between the bricks at a 45 degree angle. Twist the end of the bag and squeeze as you move the tip along the gap. The grout should over fill the gap just a little so that you have enough to tool later. This process takes some practice.
Note: Do not try to wipe off excess while the grout is wet.
Start at the top of your wall. Fill in sections of about 4 square feet at a time. Give each section about 15 minutes to dry. You can do about 4 sections one after the other before going back with your brick jointer.
When the grout is dry enough to touch without sticking to your finger, but is still soft enough to squish a little, it is ready to start tooling. Use the heal edge of your jointer to push the mortar into the gap and away from you. The excess mortar should fall away and not stick to the brick face. Use the tip to push in the short verticals and pull towards you.
As you use the jointer, if you come across a spot that doesn’t have enough mortar, pick up some of the excess that has just fallen away from the section you are working and push it into the gap. This ensures that the mortar you add has the same level of dryness as the surrounding material.
Repeat the process of grouting with the bag and then tooling with your jointer until your wall is completed.
After the grout has had some time to dry, it is time to come back and brush away any excess. Using a stiff bristle brush, start with a small section and brush the bricks with a 45 degree angle stroke. If the mortar leaves streaks on the brick faces or leaves mortar on your brush, it is still too wet. The brush will remove any high dedges and leave a nice smooth look.
