Verified by manufacturer 6 months ago
A two component, epoxy and polymer modified cementitious coating for the protection of concrete and steel substrates.
Application
- 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.
- It can also be used as a one or two coat, direct-to-metal corrosion protection system for suitably prepared steel substrates.
- Depending upon the condition of the substrate and any exposed steel reinforcement, additional surface preparation products from the Intercrete range may be required prior to the application of Intercrete 4840.
- All concrete floors, decks and highly porous substrates should be appropriately sealed using Intercrete 4850. Intercrete 4840 should always be applied directly to correctly prepared steel substrates.
- The following topcoats are recommended for Intercrete 4840: Intercrete 4870.
