There is a hole in the wall. How to fix it?

You can take the following steps to repair the hole in the wall:

1. Cleaning the hole: Clean the dust and gravel around the hole with a brush to make it clean and tidy.

2. Hole filling: evenly fill the hole with cement mixture and smooth it with filling tools (such as spatula).

3. Brush waterproof paint: Cement has no waterproof function, so a layer of waterproof paint is needed to protect the repaired wall. Waterproof coatings have a variety of materials and brands to choose from. It is recommended to choose a brand with good performance and convenient use.

4. Secondary touch-up: If holes are found after the first touch-up, secondary touch-up can be carried out, and the remaining holes can be touched up with mixture, and then coated with waterproof paint after drying.

Precautions:

1. Clean the hole around first, otherwise it will affect the filling effect.

2. Both cement and waterproof coating need to be operated according to the instructions, otherwise the effect may be poor.

3. Confirm the quality and performance of filling materials and coating materials, so as to prevent the repaired wall from being damaged or leaking again.

4. Make sure the wall is dry when repairing, otherwise it may affect the repairing effect.
