Fosroc Dekguard WB300 is a water-based, silane/siloxane-based penetrating water repellent specially formulated to protect concrete, brickwork, stone, and other mineral-based substrates from moisture ingress. Designed for long-lasting performance, it penetrates deep into the pores of the surface to create a breathable barrier that repels water while allowing trapped moisture to escape.
Dekguard WB300 is an eco-friendly solution suitable for vertical and horizontal applications in residential, commercial, and infrastructure projects. It helps prevent problems such as efflorescence, frost damage, corrosion of steel reinforcement, and staining caused by water absorption.
