印度采购需求：防水防油整理剂、防污整理剂

I'm looking for effective damp moisture treatment materials specifically designed for use in older houses. This project aims to address moisture-related issues that are common in such properties, and we need solutions that can seamlessly integrate into existing structures. Could you provide details on your available products that meet these requirements? Information regarding application methods, durability, and any certifications would be greatly appreciated. Thanks!
