Sikafloor®-619

Low viscosity epoxy impregnation

Sikafloor®-619 is a two part very low viscosity, solvent containing epoxy impregnation material. When brushed or rolled over cured concrete, Sikafloor®-619 impregnates the concrete to provide a surface with increased hardness and resistance to moisture penetration.

  • Easy to mix
  • Low viscosity for deep penetration (viscosity close to that of water)
  • Fast application
  • Reduces dusting and thus, easier cleaning of slabs
  • Increased resistance to abrasion, and mild chemicals
  • Enhanced resistance to oils, gasoline, kerosene, and staining from spillage
  • Increased impermeability of concrete and reduces rate of penetration of waterborne contaminants such as chlorides
  • Sikafloor®-619 is not a coating, therefore it will not peel or flake off

Application steps

MIXING

Pour Part B into the Part A container and mix both liquid thoroughly for one minute using a mixing paddle attached to an electric stirrer (< 500 rpm), until a fully homogeneous mix has been achieved. Decant the whole mix into another container and mix for another 30 seconds. Sikafloor®-619 is now ready to be applied.

APPLICATION

Horizontal Surface

Pour and spread Sikafloor®-619 evenly onto the prepared substrate by means of a squeegee and then backroll (cross-wise) using a short-piled roller. Avoid the formation of puddles. Apply as much material as the surface will absorb without leaving any excess material on the surface. The correct application rate will depend very much on the porosity of the concrete and should be determined on a small test area prior to large scale application.

The second coat shall be applied in the same way. For the waiting time between coats please refer to the overcoating table. A third coat may be necessary to give the required in-surface seal on porous substrates but on typical good quality dense concrete, two coats will normally be adequate.

It is important that the area is well ventilated to allow sufficient evaporation of the solvent, particularly at low application temperatures.

Vertical Surface

Sikafloor®-619 can be applied using a brush or roller.

CLEANING OF TOOLS

Clean all tools and application equipment with thinner immediately after use. Hardened or cured material can only be removed mechanically.

CLEANING

Clean regularly using a single or double headed rotary scubber drier with alkaline detergent.
