International Intercrete 4840 is a two component, water-based (VOC-free), epoxy and polymer modified cementitious coating for the protection of concrete and ferrous metals. London Underground Approval No. 2686.

Best Uses

International Intercrete 4840 exhibits a high degree of thixotropy for easy application by brush or spray to give a smooth surface finish without sagging. It cures to form a dense, highly alkaline coating offering low permeability to water and very high diffusion resistance to chloride ions and oxygen, ensuring long-term protection.

International Intercrete 4840 is specifically designed for the structural waterproofing and protection of concrete substrates where improved chemical and abrasion resistance is required. Intercrete 4840 can be reinforced with Intercrete 4872 tape to accommodate movement of cracks and joints.

Intercrete 4840 offers low permeability to water at 10 bar positive and negative pressure along with excellent resistance to carbon dioxide gas and chloride ion diffusion. It can also be used as a one or two coat, direct-to-metal corrosion protection system for suitably prepared steel substrates. Suitable for asbestos encapsulation.

CE-marked in accordance with BS EN 1504-2. Suitable for surface protection systems principles 1.3, 2.2, 5.1, 6.1, 8.2 as defined in BS EN 1504-2.

Application

Suitable for concrete and steel application. Intercrete 4840 is ideally suited to brush application, although spray techniques should be used in large areas.
