How to Grout a Brick Wall

Updated July 20, 2017

Whether brick is constructed for an interior wall or for the exterior wall, the results are the beautiful. So now that the brick is in the proper placement, now what? Now the brick will need to be grouted. This is a time consuming task that does require some skill but don’t worry, it can be learnt along the way.

Remove your dust sheet covering the finished laying brick and place it on the ground to protect the existing floor.

Put on a pair of gloves to protect your hands.

Follow the directions on the premix bag of mortar and mix it together.

Continue mixing with a trowel until the mixture resembles the consistency of peanut butter.

Fold over the open tip of your baker’s bag to prevent the mixture from escaping.

Fill the baker’s bag with mortar and test the flow of the material to ensure it is coming out in a controlled consistency.

Run your baker’s bag along the joints taking care not to get it on the brick. Take your time since mortar is hard to clean off of a bricks surface.

Read the mortars instructions for how long the grout needs to set before moving on.

Recess the joints with a half inch jointer when the grout is 100% dry.

Brush off excess mortar with cheap paintbrush and allow grout to dry for about 24 hours.
