EPOLIS EP 200

The concrete substrate must be made of concrete of at least C20/25 grade, with a compressive strength of minimum 25 MPa and a tensile strength of at least 1,5 MPa, measured by the pull-off method. The substrate must be stable, continuous, even, bonded, seasoned (min. 28 days) and dry (moisture content of max. 4%). It must be clean and free of oil, grease, cement laitance and other substances that impair adhesion. The substrate should be cleaned mechanically, dust, any loose layers and sharp protruding edges should be removed. It should be properly roughened mechanically, paying particular attention to watertight and very smooth substrates. An adherent, absorbent surface with an open pore structure should be obtained. The strength of the substrate must be adapted to the service loads.
For substrates on the ground, waterproofing or damp proofing is absolutely required.

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. 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.

All flooring materials must be seasoned for at least 24 hours in the conditions in which the flooring will be made.
Components A and B are supplied in a proper mixing ratio. Mix component A in the delivery vessel in order to homogenise. 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.
In order to prepare a repair, levelling or base mortar, an appropriate amount of quartz filler, adapted to the required application, should be gradually added to the properly mixed EPOLIS EP 200 mixture. Once all portions of the dried fine quartz sand or quartz meal have been added, mix the compound for 2 - 3 minutes until a uniform consistency is achieved. 
If partial use is assumed, the product should be prepared maintaining the weight ratio of the components (1 part component A and 0,45 of component B). It is very important to strictly adhere to these proportions and to use scales to ensure accuracy.
The permissible application time of the mixed material ata temperature of +23°C is up to 20 minutes. Increasing the temperature reduces the open time of the resin and its viscosity. Lowering the temperature increases the open time of the resin and its viscosity.
Suggested weight ratio (resin : quartz sand) and aggregate fraction are specified in Table 1 in the product's Technical Data Sheet.
The composition's versatility through adjustability and profiling of the final mix consistency is achieved by increasing or decreasing the proportion of quartz filler addition. Adding and building mixtures is always done according to tests carried out in the actual conditions of the construction site taking into account all the elements that affect the viscosity and density of the binder.
The ratios given in the technical sheet are for information only, to be verified by the user in the actual conditions of the work carried out.

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.

Priming: Apply the prepared material with a brush or roller intended for epoxy materials obtaining a thin, even layer, leaving no excess primer in the cavities. If the primer seeps into the substrate completely, repeat the priming operation. Apply the successive layer after 12 - 24 hours. After an interval longer than 48 hours, grind and dedust the primed surface.
In the case of structural priming with covering, the fresh layer of EPOLIS EP 200 should be covered with dried and dust-free quartz sand in the amount of 1 kg/m², for example with a fraction of 0,1 - 0,5 mm.

Mortar for spot repairs: Immediately distribute the prepared mixture with the addition of fine quartz fillers (see product preparation) in several portions on the designated section of the prepared substrate and then spread evenly with a steel trowel or steel notched squeegee. When using a semi-fluid putty compound with fine quartz aggregate, after spreading the compound, if aeration is visible, wait and then roll it over with a spiked roller to deaerate and level the surface.

Mortar for filling defects: Immediately distribute the prepared mixture with the addition of fine quartz fillers on the primed surface with a steel trowel or steel notched squeegee. In order to achieve good adhesion of subsequent layers, the fresh resin mortar should be completely covered with dried quartz sand for example of 0,2 - 0,8 mm fraction. The following day, brush off excess sand, lightly grind the surface in order to remove the loose grains of sand and vacuum thoroughly.

Resin screeds: Immediately distribute the prepared mixture with the addition of fine quartz fillers (see product preparation) in several portions on the designated section of the prepared substrate and then spread evenly with a steel trowel or straightedge, compact and smooth. When putty layers or resin screeds are laid as a semi-dry structural sub-base, it is important to remember to apply a layer additionally sealing the finished screed. For this purpose, use EPOLIS EP 200 binder with the addition of fine quartz sand.

Epoxy-glass laminates: After mixing components A and B, the binder should be applied in a thicker layer to the suitably prepared laminated surface using a paint brush or roller. Then, immediately place the previously prepared glass mat on top of the still fresh resin and thoroughly saturate the laminate, pressing the mat down with a saturated roller until the resin from the base fully soaks through the entire mat structure. If necessary, the surface can be re-saturated by spreading an additional layer of the compound.
For typical construction applications in the scope of laminating concrete substrates, we recommend emulsion mats with a weight of 150 or 300 g/m². The strips of glass mat laid as a continuous laminate should be joined by overlapping by a minimum of 5 cm. Successive layers should be applied after approx. 12 - 24 hours. The interval between applying successive layer of the system resin must not exceed 48 hours.

Repairing concrete structures, ‘stitching’ the floor (clamping), making facets: Before starting to ‘stitch’ the floor, the type of cracks and fissures should be determined. For the repair of ‘hairline’ cracks and scratches, after cleaning the substrate, use EPOLIS EP 200 binder without additional fillers, by trowelling or thoroughly saturating with a roller or brush. A detailed description of the repair of cracks up to 7 mm in size and cracks between 7 and 10 mm in size is included in the Technical Data Sheet of the product.

Before use, please read the application details in the product's Technical Data Sheet.
