Product Properties

Technical Data/Properties(*)

(*)Typical values in production control. All tests were executed under a conditioned temperature of 21°C and 65% RH.
(**)Consumption needs to be estimated by the designer, since it depends on the surface roughness and porosity of the surface.

Application

1. Preparation of Substrate

  • Substrate preparation has to be according EN 1504-10 part 7.
  • The substrate has to be free from dirt, grease, laitance, loose concrete, loose particles or layers which could adversely affect adhesion.
  • Remove all damaged concrete and prepare substrate by sand or grid blasting, high pressure water jetting, or other methods until base concrete is exposed, offering sufficient roughness (bond) and open pores.
  • The concrete surface needs to have an open capillary system.
  • The substrate must be frost-free.

2. Mixing

  • The product is ready to apply. It is recommended to homogenize the material before use.

4. Curing

  • Allow sufficient time for the liquid to impregnate the concrete. Time depends on porosity of concrete and ambient conditions.

5. Cleaning and maintenance

  • Mixing and application equipment should be cleaned immediately with clean water.

6. Special remarks

  • Low temperatures reduce the fluidity.

3. Application

  • OMNITEK® Realk Liquid can be applied directly on the surface by brush, roller or by spraying.
  • OMNITEK® Realk Liquid needs to be applied before application of other products such as corrosion inhibitors, primers, repair mortars or coatings.
