A brick stoop is attractive but it takes a beating from rain and snow. During freezing temperatures, the water contained in the mortar freezes, eventually cracking the bricks. To repair the stoop and prevent additional damage, remove the existing mortar and replace it. (This is called repointing.) If bricks are cracked, they will also need to be replaced. This will keep the stoop structurally sound, prolonging its lifetime.
You will need:
Step 1: Put on the dust mask and safety goggles. Use the hammer and mason’s bolster to remove mortar surrounding the damaged bricks. To chip away the mortar, hammer the bolster point into the mortar. As you work, use a brush or your hand to sweep old mortar from the area. When the space is large enough, use a large bolster and continue working. Proceed carefully so you do not damage brick that will not be removed. If the brick is damaged or cracked during this process, it will absorb moisture quicker than normal, leading the stoop to deteriorate.
Step 2: After surrounding mortar is removed, remove all damaged bricks.
Step 3: Mix the mortar, following the manufacturer instructions that came with the mortar.
Step 4: Use the trowel to apply wet mortar to a new brick. Place the brick into a space where a damaged brick was removed. Press down firmly on the brick so mortar seeps from the sides. Repeat this process for all bricks that must be replaced.
Step 5: Scrape away all excess mortar with the trowel.
Step 6: Allow the mortar to cure for one week. Use water and a stiff brush to wash away excess mortar.
