In most cases, no — polyurethane waterproofing membranes should not be applied directly over existing coatings unless the surface is properly prepared. Preparation may include grinding back to a clean substrate or using specialist primers, such as epoxy, to ensure proper adhesion. The WaterStop Shop team can advise on the correct preparation steps for your project to guarantee long-term performance.

Polyurethane liquid membrane waterproofing is highly flexible, allowing it to move with your building and prevent cracks or leaks in areas subject to structural movement. It also provides excellent resistance to water and extreme weather, making it one of the most durable options available. Choosing polyurethane means reducing future maintenance needs while extending the life of your structure.
