    Sikagard®-300 (formerly known as MasterProtect® 300) - Elastomeric, crack bridging, waterproof and anti-carbonation coating for concrete and masonry

    How does MasterProtect 300 work?

    MasterProtect 300 is a high performance elastomeric, waterproof coating based on water borne acrylic co-polymers. It is a single component, ready-to-use material which can be applied by brush, roller or airless spray. When cured, it provides an aesthetic, durable, breathable coating which is waterproof, crack bridging and protects the structure from water-borne aggressive agents such as chloride ions which initiate corrosion in the reinforcing steel and CO2 which reduces the protective properties of the concrete.
