Penebar SW Primer® is a specially formulated primer designed to enhance the adhesion between pre-formed waterstop products, such as Penebar SW®, and concrete surfaces. Its simple brush-on application ensures optimal bonding, facilitating installation and ensuring long-term performance of the waterstop system.

Ideal for use on all standard concrete surfaces, Penebar SW Primer® improves the contact and sealing efficiency of waterstops, helping to prevent water infiltration through construction joints. It dries quickly, allowing subsequent installation of waterstops without delay, and ensures reliable, long-lasting protection in both new construction and repair projects.
