The work should be carried out at an ambient temperature of +10°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. 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. The substrate should be in an air-dry condition, without any visible traces of moisture or darkening caused by moisture.
It is allowed to use the primer on a damp substrate when used under a weldable bituminous felt. Then the surface of the concrete should be in a matt-damp condition, without a glossy layer on the surface. The moisture content of the concrete after at least 7 days of curing should not be more than 15%.
Steel surfaces should be cleaned of rust and other impurities to a cleanliness grade of Sa 2½.
Check the production date on the packaging before use. The product should not be incorporated beyond its shelf life. The product, once opened, should not be objectionable and should be free of any mechanical contaminations. After mixing, the product should be homogeneous and free of lumps. When stored correctly, the product is transparent when the packaging is opened. When stored at low temperatures, partial or complete crystallisation or opacification of the product may occur, which is reversible and does not affect the quality of the product. After 24 hours of seasoning under normal conditions, the product, when mixed, reaches a homogeneous consistency and full clarity.
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. 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.
If partial use is assumed, the product should be prepared maintaining the weight ratio of the components (100 parts component A and 23,5 of component B).
The permissible application time of the mixed material at a temperature of +20°C is up to 45 minutes.
The coating can be applied by a brush or roller.
Pour the mixture onto the prepared substrate and spread with an appropriate tool, obtaining a thin, even layer and leaving no excess primer in the cavities.
If levelling compounds or adhesive cement mortars are to be used on the coating of EPOLIS EP 601, the freshly primed surface should be sprinkled with quartz sand of grain size 0,4 - 0,8 mm. Once the primer has set, excess sand should be removed. When applying EPOLIS EP 601 under weldable bituminous felt, the version with or without sand can be used.
Apply subsequent layers to the primed substrate no later than after 24 hours. After a longer interval, the primed surface must be sanded and dusted.
Before use, please read the application details in the product's Technical Data Sheet.
