Sikafloor ® -161 Sikafloor ® -263 SL Sikadur ® -504
Description •
Sikafloor ® -161 is a low viscosity, solvent free, 2-component epoxy primer, for use on absorbent substrates. Sikafloor ® -263 SL is a 2-component, economic, multi-purpose, epoxy resin based binder. Sikadur ® -504 is a selected quartz sand of special gradings used as component C (filler) for Sikafloor ® self-levelling systems (0.08–0.2mm).

equivalent methods. Note: Surface contamination can be removed by high pressure water jetting (Min. 150 bar) with the addition of suitable detergents. Concrete parts where oil has penetrated into the concrete must be removed mechanically. Oil contamination can be checked by dropping water onto the surface. If a hydrophobic effect is visible, the surface is contaminated. Repair minor damages, honeycombing or defects in the concrete surface with Sikagard® -720 EpoCem ® or Sikafloor ® -161 Mortar . Larger breakouts can be repaired with Sikadur ® -31/41. The substrate must have a minimum compressive strength of 25 N/mm2 and minimum surface tensile (pull-off) strength of 1.5 N/mm 2. The moisture content of the substrate must be below 4%; other wise, a temporary moisture barrier with 2mm minimum thickness of Sikafloor ® -81 EpoCem ® must be used. Thorough vacuuming before priming is absolutely necessary.

Apply the primer coat of Sikafloor ® -161 by roller using a consumption of 0.15 0.5 kg/m² depending on absorbency and roughness of the substrate. Ensure complete wetting out of the surface. Wait until tack free before applying following coats (min. 8 hours, max. 24 hours @ 30°C. Important: The concrete must be completely sealed, and shall not have any absorbency prior to the application of the broadcast.

Self-levelling Mortar Pour the Sikafloor ® -263 SL mortar and spread it equally over the area by means of a notched trowel according to the required thickness (4x4 mm notches will give 2mm thickness). Immediately use a spiked roller to remove any entrapped air. Use a consumption of approximately 1.9 kg/m2 of mixture per thickness of 1 mm. Leave the Sikafloor ® -263 SL mortar to cure for at least 5 days (at 30ºC) before full exposure.
