Features
- Epoxy resin consisting of two pre-dosed components (component A: resin and component B: hardener), which must be mixed together before use.
- Can be applied on both smooth and rough surfaces.
Advantages
- Excellent horizontal and vertical adhesion to concrete and steel.
- Very good mechanical strength.
- Resistant to weather and chemical agents.
- Protects reinforcement against corrosion.
- Hardens without shrinking.
Benefits
Allows for fast and secure joints between old and new concrete.
Allow at least 28 days of curing time for new concrete and mortars before application.
Do not add solvents, water or other substances that could affect the product.
These instructions are merely recommendations based on our experience. We recommend performing tests for each new type of application or surface to be treated.
Datasheets(X)
A bond to join fresh concrete with hardened concrete.
Bond between different common building materials such as concrete, stone, marble, wood, glass and ceramics.
Preparing the substrate: The substrate must be clean, solid, healthy and free from paint, dust, plaster or any substance that may affect the product's adhesion. There must be no rising damp due to capillary action and the surface moisture of the substrate must be less than 4 %.
Preparing the mixture: The hardener, component B, is poured into the package of component A. The components are blended at 300 rpm until a product that is uniform in colour and appearance is obtained. For 5 kg, at a temperature of 20°C, the pot life is 75 minutes.
Application: Apply with a short-haired brush, roller or spatula. Apply a thick, even coat. Apply at temperatures between 10 and 30°C. At temperatures below 5°C the product does not harden.
Storage
Maximum recommended storage time: One year in its original container, well sealed and sheltered from the elements (under cover at a temperature between 5°C and 35°C).
