New Bricks

If you have an old brick sidewalk that is damaged and need of repair, you will need to replace the broken parts of the walkway. Repairing a damaged brick sidewalk is not difficult, and this simple how-to guide will show you everything you need to know. Let's get started.

Step 1 - Remove Damaged Bricks and Mortar

First, you'll need to break up any damaged bricks or mortar in your brick sidewalk. To do this, use a sledgehammer to break up broken or damaged brick, or use a hammer and chisel to break away any cracked or damaged mortar. Once you break out the bricks or mortar, simply place them in a spare container so that you can dispose of them later.

Step 2- Clean the Area

Use a regular straw broom to sweep the area where you removed the damaged bricks or mortar. Try to remove as much mortar dust and brick fragment as possible.

Step 3 - Mix Mortar

Refer to the instructions on the bag of mortar mix for properly mixing the mortar. You will need to add water in most cases, and you can use a concrete trowel and small pan or container to mix the mortar. When mixing the mortar, don't mix too much at one time. Mix only enough mortar for about one or two hours of work.

Step 4 - Place New Bricks

Now, you can begin placing the new bricks that will be needed to repair the brick sidewalk. Simply lay the bricks in the same manner as the damaged bricks that you removed earlier. In some cases, you may have to use a concrete trowel to gently dig out small amounts of dirt so that the bricks can lay flat. Lay out your brakes before using the mortar.

Step 5 - Apply Mortar Mix to Seams

Making sure that the bricks are evenly spaced, begin using the mortar trowel to place the mortar between the seams of the bricks. Fill the seams between the bricks until the height of the mortar is about 1/2 inch below the top surface of the brick. Alternatively, you can fill this seems to a depth that matches the undamaged brakes in the sidewalk.

(Note - You can also use the mortar bag or cake icing bag to make filling the seams with mortar a little easier.)

Step 6 - Strike with Jointer

Before the mortar has a chance to set or dry, take the jointer and strike the seams between the bricks. Striking the seams is simply using the tool to smooth out and spread the mortar in the seams so that is flat or slightly beveled. You'll use the jointer to match the seam for the new bricks with the old ones as closely as possible. (Tip - If you don't have a jointer use your finger to smooth the seams.)
