Flowprime OT is a two–component epoxy resin membrane that is tolerant of residual oil contamination in concrete floors. However, it is essential that all surface and gross contamination is removed by cleaning with an industrial detergent.

Flowprime OT is designed to improve the adhesion of coatings and screed systems to substrates that have previously been contaminated with oils, and have been thoroughly cleaned but may still retain some residual contamination. Flowprime OT will not bond to grossly contaminated surfaces where sufficient cleaning and preparation has not been carried out.

Advantages

  • Solvent free, low odour
  • Excellent adhesion to damp concrete
  • Low viscosity, easily applied.

Coverage

4 /kg/coat depending on surface texture. Coverage will be reduced by rough, porous substrates.

Cure Schedule @ 20ºC

Working life of full packs** - 20 minutes
Over-coating time (minimum) - 12 hours
Over-coating time (maximum) - 36 hours

*The above cure times are approximate and given as a guide only. These times can vary due to prevailing site conditions. Higher temperatures will shorten working time and lower temperatures will extend cure times.

** Usable working life of material following mixing and immediate spreading as per the application instructions.

Surface Preparation:

Concrete surfaces shall be mechanically prepared so that the concrete is clean and free from dust, laitance, grease, oil, curing compound, existing paint finishes, etc. Suitable mechanical treatment such as vacuum grit blasting or mechanical scabbling are recommended to ensure the removal of contaminants and to provide a mechanical ‘key’ for the Flowprime OT. A proprietary de-greaser should be applied to the contamination as per manufacturers instructions, thoroughly worked into the surface and allowed to sit for at least 20 minutes. Agitate with a scrubber and rinse thoroughly as per manufacturers instructions. Several cleaning cycles may be required. Finally, rinse the surface thoroughly with clean water to remove residues and allow to dry. Inspect the resultant surface and that no residual oil is rising from the screed. Surfaces must be free from liquid water and the atmosphere must be free from condensation. Refer to the Virtus Guide to Surface Preparation for further information..

Application Conditions:

The ideal ambient and substrate temperature is 15 - 25 ºC. Localised heating or cooling equipment may be required outside of these parameters. Do not proceed with application if atmospheric relative humidity is, or is anticipated to be >90% or if the temperature is, or is anticipated to be <5ºC during the application or curing period. The substrate and uncured floor must be kept at least 3°C above the dew point for at least 48 hours after application.

Mixing:

Flowprime OT is a two-component product. Fully drain the contents of the hardener component into the coloured resin component and mix thoroughly with a slow speed electric stirrer fitted with a spiral paddle, for a minimum of 3 minutes until homogeneous. Important: Both liquids are pre-weighed and designed to be mixed together in their entirety. It is essential that the full amounts are mixed together and until homogenous to ensure the product cures correctly and to the desired finish.

Sealing:

Apply by short or medium pile roller at a nominal rate of 0.25 kg/m². Make sure that the substrate is completely wetted out and work thoroughly into the surface using more mechanical agitation than would normally be used to apply a coating/primer. Additional coats or further toppings must be applied within 48 hours.
