APPLICATION
SURFACE PREPARATION
-
Concrete sub-surfaces may be free from all foreign materials such as clean, dry and all kinds of dirt, oil, grease, coaitng and surface treatments. In addition, should also have strong and sufficient compressive strength (minimum 25 N/mm2), the tensile strenght should also be at least 1,5 N/mm2.
-
Concerete sub-surfaces should be prepared by using abrasive equipments and by removing cement slurry in order to obtain open porous structure. Weak concrete parts should be removed from surface, bird's eye gaps and holes should be completely closed. Sub-surface repairs, filling the gaps and leveling the surface are made by the mortar obtaining by mixture of 0,1 mm- 0,3 mm silica sand and EPOFLOOR PRIMEL plaster.
-
Concerete and screed surfaces should be primed and leveled in order to obtain a smooth surface. Heights on the surface should be leveled by abrading. All dust and loose particles should be removed from the surface preferably by brush and/or vacuum cleaner.
APPLICATION CONDITIONS
-
Surface moisture content must be less than 4%.
-
Test method: CM measurement or Stove-drying method (moisture meter) Relative humidity must not exceed 80%.
-
Care should be taken to dew and condensation.
-
Dew and water vapor condensation damage the coating on untreated or new treadet floor, cause bubbles to form. To prevent this, temperature of the surface and uncured floor must be at least 3 °C more than dew point.
-
Surface Temperature: Minimum +10 °C, maximum +30 °C
-
Ambient Temperature: Minimum +10 °C, maximum +30 °C
-
Material Temperature: Minimum +10 °C, maximum +30 °C
PREPARATION AND APPLICATION OF MORTAR
-
Before mixing, A component should be mixed mechanically. After B component is poured into A component, until obtaining a homogeneous mixture, it's stirred for 2-3 min. by a mixer with 300-400 rpm. Then by 0,1-0,4 mm silica sand and if necessary other fillings are added and until obtaining a homogeneous mixture, it's stirred again about 2-3 min. In order to make sure that the mixture is fully prepared, materials are transferred into another container and stirred again for 1 minute. In order to minimize air entrainment, over stirring must be avoided.
-
Placing Coating: EPOFLOOR COAT is poured on the surface and spread evenly by scraped trowel. Then the surface is flatten and entrainmented air is removed by spiked roller. Spiked roller application should be performed after 15 minute (at + 20 °C). In case of late performed, roller traces may be left on the surface.
-
As Floor Paint: EPOFLOOR COAT can be applied as paint by short pile roller. In order to prevent roller trace and removing gaps, roller application should be performed in the transverse direction.
-
Final Coat Thin Coating: Final coatings are spreaded by rabble, then can be passed over (in transverse direction) by short pile roller.
CONSUMPTION
Protection of Concrete Floor (Application by Dye)
Primer: EPOFLOOR PRİMEL 0,3 kg/m2 – 0,5 kg/m2
Dye: 2 coats x EPOFLOOR COAT 0,3 kg/m2 – 0,5 kg/m2 Apply for each coat.
Self Spreading System (1,5 mm – 2,5 mm):
Primer: 1 coat x EPOFLOOR PRİMEL 0,3 kg/m2 – 0,5 kg/m2
Coating Layer: EPOFLOOR COAT 2 kg/m2 – 3,5 kg/m2
Multi Layer Coating (Multi Layer Screed) 4 mm:
Primer: EPOFLOOR PRİMEL 0,3 kg/m2 – 0,5 kg/m2
Base Coating: EPOFLOOR COAT + silica sand (0,1 mm – 0,4 mm, 1:1 mixture) 2,8 kg/m2
Sandblasting:Silica sand (0.4 mm - 0.7 mm) is sprinkled on the surface.
Final Layer Coating: 1 coat COAT EPOFLO x 0.8 kg / m2
These values are theoretical and don't include additional material requirement depending on surface porosity, surface profile, differences in level and wastage.
Consumption: About 2,8 kg/m2 for 2 mm thickness.
