how to repair hole in cinder block wall

1. Clean debris from holes and gaps larger than ½ inch in diameter with a stiff bristle brush.
2. Mix sack-type mortar mix with water as directed on the package in a plastic bucket. Mix only as much as you need.
3. Spray the surface and inside edge of the cinder block hole with enough water to dampen the block but not so much that the water runs down the wall.
4. Scoop up about ¼ cup of prepared mortar mix with a small masonry trowel and apply it to the hole, working the mortar into the gap.
5. Continue filling the hole all the way around the pipe, using the trowel to smooth the mortar evenly against the surface of the cinder block.
Scrape off excess mortar with the trowel while it’s still wet.
Let the mortar dry completely before repainting the wall, if desired. For a finished look, you can conceal the area you just fixed with a pipe wall plate.
