The works should be carried out at an ambient temperature of +15°C to +30°C, with a maximum relative humidity of 70%. Higher temperatures and humidity accelerate the setting time of the mix. At lower temperatures, a delay in setting is to be expected, as well as a change in the consistency of the material and as a result of that an increase in consumption. The temperature of the substrate must always be at least 3°C above the dew point temperature until the material is fully cured.
Works should not be carried out during precipitation and strong sunlight.
The premises where the work takes place must be sectioned off, protected from unauthorised access and a safety zone must be maintained against the use of open flames, particularly before conducting welding work. During the works, very good ventilation of the work area should be ensured.
The concrete substrate must be made of concrete of min. C20/25 grade, with a strength of at least 1,5 MPa measured by the pull-off method. The substrate must be stable, continuous, even, bonded, seasoned and dry. It must be clean and free of oil, grease, cement laitance and other substances that impair adhesion. The substrates should be cleaned mechanically, dust, any loose layers and sharp protruding edges should be removed.
Steel surfaces should be cleaned of rust and other impurities to a cleanliness grade of Sa 2½.
Prime the substrate with the NEXLER EPOLIS EP 601 product. After the primer has dried, no later than after 24 hours, apply the EPOLIS EP 602 membrane.
Components A and B are supplied in a proper mixing ratio. Mix component A in the delivery vessel in order to homogenise and evenly distribute the mineral filler and colour. Then add the total amount of ingredient B and mix with a mechanical stirrer at 300 - 600 rotations per minute for approximately 3 minutes. While mixing, scrape the mixture from the sides and bottom of the vessel with the mixer to ensure thorough distribution of the hardener. After mixing, pour the material into the working vessel and mix again.
With traffic load, after mixing components A and B, gradually add quartz sand with a grain size of 0,8 - 1,2 mm at a weight ratio of 1 : 1. Mix the components until a homogeneous consistency is obtained (approx. 3 minutes). Pour the mixed material into a clean container and mix again.
If partial use is assumed, the product should be prepared maintaining the weight ratio of the components (1 part component A and 0,54 of component B).
The permissible application time of the mixed material at a temperature of +20°C is up to 45 minutes.
When fresh, check the consumption of the material per unit and/or dedicated area on an ongoing basis.
The appearance of the completed coating depends on the ambient temperature and humidity, the absorbency of the substrate and the method of application.
The bonded coating should have a uniform texture, without bulges, air bubbles, wrinkles or cracks.
Individual batches of the product may vary slightly in shade of colour. Ensure that architecturally separated substrate surfaces are coated with resin from the same production batch.
The coating can be applied by a brush, roller or notched trowel.
After unfolding, immediately level the surface with a spiked roller to deaerate the membrane. The recommended thickness of the coating applied in one working operation is 2 - 3 mm. In the case of heavy loading, an additional backfilling of quartz grit with a grain size of 0,8 - 1,2 mm, in an amount of 2,0 - 2,5 kg/m², is recommended. Apply the grit to the still fresh, unbound membrane.
After 24 hours, sweep up the excess grit.
The interval between the application of layers of EPOLIS EP 602, or any other resin, should be approximately 24 hours.
Before use, please read the application details in the product's Technical Data Sheet.
