Surface waterproofing over old waterproofing

Old waterproofing on roofs can consist of a wide range of materials, the most common of which include elastomers, polymers and bitumen. These building materials have very different chemical and physical properties. The challenge lies in creating a functional and long-lasting adhesive bond with the new waterproofing layer. The answer? MB PUReactive and MB PUReactive TX. The PU hybrid waterproofing product reliably seals all materials, whether it is applied with a roller or by spraying. And MB PUReactive+ works just the same way, and can even be used without any fabric reinforcement.
