Build a brick wall to create some privacy in your yard, contain soil, divide property lines or as a retaining wall for a plant bed. It can be challenging to build a brick wall, which is why in most cases they’re only built by those people trained and experienced in masonry. However, if you would like to build a smaller brick wall, you can certainly do so by following these steps.
Cut two-foot square pieces of plywood to act as mortar boards. Prepare the mortar. Mix it by hand in a wheelbarrow. Mix it in halves to make the job easier. Put the mortar on a few mortar boards and place them near where you'll be building your brick wall so that they're within easy reach.
Repeat Steps 4 through 6 until you've finished your brick wall.
Lay down your first layer of bricks from left to right. Straighten the bricks, as needed, using your level as a guide. Hold the level vertical against the bricks to make sure they are square and level. Use the trowel to remove any mortar that squeezes out from under the brick and stick it underneath the next brick you'll be putting down.
