Find the source of the leakage
If you want to block the water, you must first know where the water comes from. Check the external wall carefully, which may be caused by broken bricks and cracked paint. Only by finding the source can we prescribe the right medicine.
Repair external wall
Don't let the small break become a big problem. Once any damage or cracks are found, fill them with cement mortar or sealant. Ensure that the repair material is completely filled and flush with the wall to prevent water from infiltrating again.
Waterproof layer reinforcement
If the exterior wall paint is not waterproof, consider brushing a layer of waterproof material. This protective film can effectively prevent moisture from entering the inner wall and improve the waterproof performance of the outer wall.
Indoor waterproof measures
Don't forget to protect the inner wall when dealing with the seepage of the outer wall. Painting waterproof paint and installing waterproof membrane or waterproof board can provide additional protection for the interior wall.
Keep it ventilated and dry.
Indoor air circulation and humidity are appropriate, which can effectively reduce the interior wall from being damp. Once the water leakage problem is found, repair it in time to avoid water retention.
Find a professional
Before starting work, it is recommended to find a professional to check and evaluate to ensure that the measures taken can really solve the problem. Don't forget, safety comes first!
