EPOLIT W
Twocomponent watersoluble coating system on the basis of low molecular modified epoxy resin
Product Characteristics
Two-component water-soluble coating system on the basis of low-molecular modified epoxy resin intended for protection and surface finish of concrete and concrete structures as well as for surface finish of cement and polymer cement repair mortars and cement plasters and stuccoes.
- Supplied in specified rate of particular components; no weighting in-situ is needed
- coating can be applied to moist bases (up to 8%)
- provides aesthetically desirable surface finish
- highly abrasion resistant
- permanently resistant to aggressive effect of number of acid and alkaline media, oils, oil products, etc.
Use
EPOLIT W is two-component water-soluble epoxy composition, which is intended for fabrication of protective coatings of concrete and reinforced concrete structures as well as for surface finish of cement and polymer cement repair mortars and cement plasters and stuccoes. It is used especially in places, where enhanced resistance of building structure surface to effects of aggressive media, absolute dust-free surfaces, washability, etc. are required. It is compatible with the permanently flexible spreaded coating WATERFIN PV.

Instruction for preparation and application
Base. Any incoherent, loose or weatherworn particles shall be removed from the base. The surface cannot be contaminated by substances negatively effecting adhesion of the coat to the base (fats, greases, oils, etc.). Tensile strength of surface layers of the base shall be 1.5MPa at least. Corroded reinforcement and visibly damaged concrete shall be properly repaired. When coating is applied, the new concrete shall be 28 days old at least and moisture of the base should not exceed 8%.
Penetration of the base. The first step, which precedes the finishing coat itself, is penetration of the base. The composition EPOLIT W diluted in the following rate is used for penetration.
| EPOLIT W – component A | 5 weight parts |
| EPOLIT W – component B | 1 weight part |
| water *) | 0,5 – 1,5 weight parts |
| *) Water quantity depends on absorbance of the base | |
Penetration is applied preferably by a roller or, possibly, a brush in quantity amounting approximately to 100 ÷ 150 g/m2 in dependence on absorbance of the base. Penetration may not create any film on the concrete surface.
This composition is prepared by proper mixing of components A and B in specified rate. The mixing rate is the following:
| EPOLIT W – component A | 5 weight part |
| EPOLIT W – component B | 1 weight part |
Components A and B are mixed in a sufficiently voluminous vessel by an electrically driven low-speed propeller agitator.
Workability. Workability of prepared composition depends to certain extent on ambient temperature. The prepared
composition is workable 120 minutes under 20 °C. The prepared composition shall be efficiently protected against desiccation. It is also recommended to mix it from time to time.
Neither temperature of the base nor temperature of ambient air shall be below +5 °C and above +30 °C.
Application of the coat. The first step is penetration of the base. Penetration is applied preferably by a roller or,
possibly, a brush in quantity amounting to approximately 100 – 150 g/m2 in dependence on absorbance of the base.
EPOLIT W is applied in two layers with technological break of 24 hours. It is applied preferably by a roller or, possibly, a brush in quantity amounting to approximately 300 – 350 g/m2 per one layer.
If EPOLIT W is applied by spraying, it is practical to adjust its consistence by water in quantity up to 25%
Open time. After mixing the so-called open time of both penetration and coating is max. 120 minutes under 20 °C. It is necessary to take into account that the open time is significantly reduced with increasing temperature.
Dilution. The composition can be diluted by drinking water or water with similar quality, if any. Working aids and tools shall be washed in warm water with added detergent immediately after completion of work. It is also possible to use acetone for perfect cleaning of tools and aids.
Specific consumption Specific consumption of the penetration EPOLIT W amounts to 0,1 ÷ 0,15 kg/m2 in dependence on roughness and absorbance of the base. Specific consumption of the coat EPOLIT W amounts to 0,3 ÷ 0,35 kg/m2 per one layer in dependence on roughness of the base. This consumption ensures that the hardened film is approximately 120 – 150 µm thick
