30 minutes at +20°C
After 16 hours at +20°C further treatment can be initiated
Min. 6 months in unopened container.
Concrete in situ and concrete slabs, older than 3 months.
Cohesive strength should be min. 1.5 N/mm²
The surface should be dimensionally stable, sound, clean and free from dust and laitance. There should be no blooms or crack formations. Surface evenness of +/- 2 mm when using smoothing board. Residues from grease or soap can be removed with Alfix Deep Cleaner.
How to use
Add full content of component B into component A and mix the two components using slowly rotating paddle attached to electric drill. Mix thoroughly for approx. 3 minutes.
Working time is approx. 30 minutes at +20°C.
Apply by short pile paint roller to an evenly penetrating coat with coverage of 200 – 300 g/m².
Scatter with dry quartz sand, type 1, over the still wet coating of Alfix Epoxy primer until the surface is completely saturated and will provide a sandpaper-like finish.
Both substrate and working temperature should be ranging between +10°C - +30°C.
Avoid working in direct sunlight.
According to Danish legislation, working with epoxide products requires special training.
Residues from Alfix Epoxy primer on tools should be removed immediately upon use with ethanol.
Once cured, primer can only be removed mechanically.
