Description:

A two component, water-based (VOC-free), epoxy and polymer modified cementitious coating for the protection of concrete and ferrous metals. It 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.

Features & Benefits:

• Unique blend of surfactants enables easy brush or spray application. Produces a smooth finish, which rapidly recovers to prevent sagging.
• Pre-packaged material only requiring mixing on-site.
• Excellent adhesion to cementitious and steel substrates.
• Resistant to a range of chemicals and gases, including hydrogen sulphide.
• Excellent abrasion and impact resistance.
• Dense matrix offers low permeability to water at 10 bar positive and negative pressure and very high diffusion resistance to carbon dioxide gas and chloride ions.
• Hydrates to provide an alkaline environment which chemically reacts with the substrate to accelerate the passivation of steel and enhance the bond to concrete.
• Water-based, cures without the release of hazardous solvents. Equipment easily cleaned with water.

Uses:

• 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.
• 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.
