Step 1: Using a carton knife, or carbide-type method to carve a V-shaped groove behind the sides of the hole in troughs greater than 1/2 inch in diameter. This allows the patching compound to be locked behind the cement board. To scrub out the region to be covered, use a wet, moist sponge.

Step 2: Mix a small amount of thin mortar according to the directions of the maker. Thin-set mortar normally has fewer than 15 minutes, but smaller batches are the best option. Evenly spread the mortar to level the wall.

Step 3: Once the patch is dried we need to sand the mortar. Always use protective gears such as approved masks or respirators while sanding.

Step 4: Use a carton knife to score and break a fresh sheet of cement board through the new hole. Enter the current board with corrosion-resistant screws. For faster mounting, pre-drill the screw holes. Make sure you carry a respirator and eyewear while you simmer. Cover the voids with a sheet of thin-set fibreglass-capped mortar. Sand the mortar as needed, smooth and we are done.
