Two component solvent-free epoxy adhesive for construction joints and for monolithic sealing of cracks in screeds
- Monolithic construction joints between fresh and hardened concrete
- Bonding precast concrete elements
- Bonding steel to concrete
- Filling cracks in concrete
- Construction joints for the structural reinforcement of beams and pillars
- Construction joints on decayed industrial flooring
- Rigid, waterproof construction joints (e.g. concrete bed to tank walls)
- Sealing cracks in cement screeds
- Consumption
- 0.5-0.7 kg/m² on rough substrates, 1-2 kg/m² on very uneven ones
- Pack we stock
- 2 kg set
Coverage calculator
How much you need.
The arithmetic uses Mapei's published consumption for Eporip and the pack sizes we stock. Set your own wastage allowance.
You need
6-8
x 2 kg kit (A 1.5 kg + B 0.5 kg)
- Data sheet quantity
- 10-14 kg
- With 10% wastage
- 11-15.4 kg
The figures behind it.
- construction joints with a rough substrate: 0.5-0.7 kg/m²
- construction joints with a very uneven substrate: 1.0-2.0 kg/m²
- sealing cracks: 1.35 kg/l per litre of cavity
- bonding precast elements in concrete, or steel-and-concrete: 1.35 kg/m² per mm thickness.
Consumption on site depends on the substrate, the tool and the applicator, which is why wastage is yours to set. The result is a quantity to plan and quote with, not a guarantee of coverage. Confirm the system against the current Mapei technical data sheet before ordering.
