DIY Leak Repair & Waterproofing Kit for Typhoon-Prone Walls

The user explicitly mentions a leaking wall during heavy rain/typhoons and is 'trying to patch that up too,' highlighting a clear unmet need for an effective, accessible DIY solution for structural waterproofing. This product could be a comprehensive kit for homeowners, including strong, flexible sealants (e.g., polyurethane or rubberized asphalt), a primer, application tools, and clear instructions. It would be designed to create a durable, weather-resistant barrier against water ingress in masonry or concrete walls, particularly suitable for high-precipitation and typhoon-affected regions like the Philippines, empowering homeowners to fix the root cause of their wall issues.
