A two-component epoxy resin membrane that is tolerant of residual oil contamination in concrete floors. It is essential that all surface and gross contamination are removed by cleaning with RS Oil pre-treatment and RS Industrial floor cleaner.

Can be used on concrete floors and fine concrete screeds, of not less than 50 mm thick, in the case of unbonded screeds. The surface must be of sufficient quality, continuity and mechanical strength to ensure an even coating.

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.

The product may also be applied to polymers, screeds and certain types of smoothing underlayments, provided these are well bonded.

Advantages:

  • Enables resin finishes to be applied onto concrete that has previously been contaminated with engineering oils.
  • Easily applied by brush, roller or trowel edge.
  • Can be applied onto substrates with hygrometer readings up to 85% RH.
  • Completely solvent free and low odour.

Chemical resistance:

  • Good resistance to mild chemical attack but is designed to be overcoated with other resin finishes.

Product properties at 20°C:

  • Coverage: 16 m² per 4 kg unit at 220 microns dry film thickness.
  • Over-coating time: Allow 10 hours.
  • Application temperature limits: 5–30°C.

Standard product features

The surface will require thorough preparation before applying. The surface will also have to be treated with R.S Oil Remover and the cleaned with R.S. Industrial Floor Cleaner.
