Moisture Vapour Suppressant

ES600 is a ready for use, one part, water-based moisture vapour suppressant.

A surface moisture vapour suppressant developed to suppress residual construction moisture in cementitious subfloors including power floated concrete and sand/cement screeds.

  • Guarantees the early satisfactory laying of floor coverings to sand/cement and concrete bases where moisture content is up to 95% RH
  • Rapid drying - approximately 1 hour at 20°C
  • Easy to apply – primerless application and single component, no mixing required
  • Water based, low VOC compliant
  •  Suitable for heated concrete and sand cement screeds (provided the surface temperature does not exceed 27°C in accordance with BS 8203 and BS 5325)

Moisture Testing
(in accordance with British Standards 8203)

  • Hygrometer readings must be taken and recorded so that the correct system can be selected.
  • Concrete curing compounds and over-trowelled concrete will extend the time taken for the hygrometer to reach equilibrium.
  • Subfloor measurement readings of up to 95% RH (measurable) can be accommodated with the system.


Condition the contents by storing for 24 hours at +15°C to +25°C as cooler temperatures will increase viscosity and make application more difficult. Higher temperatures will speed the chemical reaction and therefore reduce working
pot life.


  • The surface must be firm, sound, clean, dry and free of any other contaminants liable to prevent penetration into the substrate or adhesion to the surface.
  • All dust and plaster deposits must be removed and vacuumed.
  • Remove all surface water. Highly polished surfaces or concrete containing a curing agent or surface hardener may require shot blasting.
  • Power floated concrete must be abraded or shot blasted to provide a good key for adhesion.


  • In most circumstances no priming is required.
  • For further information please contact tremco illbruck Technical Services.


Note: drying times are based on ambient conditions, and will be slower in cold
and/or wet conditions. Good ventilation is essential.

  • Shake the bottle to mix contents immediately prior to use.
  • Pour into a rectangular bucket or paint tray.
  • ES600 must be applied in two coats.
  • 1st Coat: Pre-wet a roller in the ES600.
  • Apply the 1st coat in one direction ensuring that the worked material is well into the substrate.
  • 2nd Coat: When the 1st coat is touch dry, approximately 15-30 minutes at 20ºC, apply the 2nd coat in a direction at right angles to the 1st coat.
  • It is essential that a pin-hole free coating is achieved and to maintain a coverage rate of 32 m² per 5kg per coat (i.e. 5 kg unit covers 16 m² @ 2 coats). The overall dry film coating thickness should be a minimum of 150 microns.
  • Allow to dry to a tack-free film. At 20ºC the drying time will be approximately 30 to 60 minutes on the first coat and 60 to 120 minutes on the 2nd coat.
  • Cover with a minimum 3 mm thickness of an appropriate TREMCO smoothing compound to provide an absorption medium for any subsequent adhesive.
  • It is not always necessary to cover ES600 with a smoothing compound as certain TREMCO adhesives may be applied directly.
  • In all cases it is advisable to apply the adhesive between 1 and 2 days after the final coat of ES600. For further information contact tremco illbruck Technical Services.
