Casey Thebolt on porch repair

Instructions
1
Remove any cracked and crumbling mortar from between the bricks carefully with a chisel. Hit the back of the chisel with a hammer to chip away the damaged mortar. Or grind oout the mortar with a diamond blade.

2
Spray down the porch to remove any loose dirt. Use a high-pressure washer if there are large amounts of mineral deposits, grease or other stuck-on matter. If the water beads in places, there is a previously existing, but worn, sealer. Coat the brick with environmentally-safe concrete and masonry stripper and leave it to sit for the time indicated in the directions. Rinse with fresh water.

3
Scrub the porch with an environmentally-safe concrete and masonry cleaner and etch solution while it is still wet. Dilute the product if instructed to do so. Rinse the porch with water.

4
Dampen the areas where mortar was removed before adding new mortar. These surfaces need to be moist for adequate mortar adhesion. Spread mortar into the gaps with a point trowel. As the mortar starts to set up, smooth it down with a jointer tool or the end of a wooden dowel. Allow the mortar to fully cure, misting the repair areas with water regularly during the curing process.

5
Apply concrete and masonry stain to the bricks to enrich their color if desired. Apply the stain with a sponge or paintbrush and be careful not to stain the mortar joints. Allow the stain to dry.

6
Apply penetrating concrete and masonry sealer to the porch to protect the bricks from staining, moisture damage and sun fading, and to preserve any color enhancement. Apply penetrating sealer with a paintbrush, roller or sprayer. Coat the porch generously and allow the sealer to soak in.
