In this Build It, Ask This Old House mason Mark McCullough teaches Kevin O’Connor how to patch holes in a tough surface.
Steps for Patching Holes in Brick
- Find a mortar mix or compound that matches the existing brick as closely as possible (an exact match isn’t likely)
- Using water sparingly, mix the compound or mortar mix to a thick putty-like consistency. It’s better to add small amounts of water a little at a time than trying adding material to a wet mix.
- With a bit of the compound on a trowel, use a hex key or something similar to pack small amounts of the compound into the hole until the hole is filled to be slightly proud of the brick surface.
- Use a trowel to flatten the compound against the brick. Press down and use a small circular motion—don’t drag the trowel across.
- Using a damp sponge, press the sponge against the patched hole and then lift it straight off the brick to mimic the rough surface of the brick.
