ERADUR® PRIMER WS
Product type
Two-component, solvent-free, clear and uncoloured epoxy primer.
Application areas
Primer for damp surfaces.
Primer on green concrete.
Also suitable for dust binding, gluing etc.
Properties:
- Primer with very good adhesion to concrete and other mineral substrates, even to damp surfaces, which, for example, have been rinsed off but not completely dried up before laying.
- Can be used as a primer on newly laid, so-called green concrete, residual cement skin gives poor adhesion which priming can not remedy.
- It is not suitable for so-called additional moisture.
- It is only suitable as a primer due to yellowing and an inheretly dark-color.
- Reinforces the concrete. Excellent for dust binding, gives the concrete a dense, durable, chemical-resistant surface (especially against mineral acids).
Application temperature
Operating temperature (floor temperature): 5–30 ° C. High temperature results in a shortened application time but does not involve any technical disadvantage.
Pot life
Pot life after mixing approx. 50 min.
Curing time
8–16 hours before the application of coating or painting. 24 hours for pedestrians and lower loading. 5–7 days for complete curing and resistance.
Mixing ratios
