abe.®cote vapour barrier

Epoxy resin vapour barrier for concrete floors

abe.®cote vapour barrier is a solvent free, two component epoxy resin system designed to reduce moisture vapour emission through concrete.

  • Moisture vapour barrier
  • Surface primer on concrete floors
  • Easily applied
  • Reduces water vapour permeability rates through concrete
  • Decreases outgassing through concrete
Substrate Requirements

The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm2).
All contamination must be removed to give a clean, dry and open textured surface.
Substrate must be free from rising damp.
Dry to a moisture content below 75% RH as per BS 8203; 1987.
Determine the moisture vapour emission rate (MVER), as described in ASTM F1869, of the concrete floor prior to application.
Do not apply coating if the substrate temperature is >3 ºC (5 ºC is better) above dew point.

Surface Preparation

Laitance and contamination to be removed by totally enclosed shot blasting, light scarification or diamond grinding. All residues must be removed including vacuum cleaning to provide a dry, dust free, open textured surface. Porous substrates will require additional coats of abe.®cote vapour barrier


Do not part mix. Kit components are preweighed for optimum performance.
Do not mix by hand.
Pour activator into the base (drain container completely). Ensure that all components are thoroughly mixed using a slow speed industrial hand drill, Helical mixer or Jiffy mixer.

  • Refer to recommended specification.
  • Apply in a single coat at the specified application rate of 250 – 400 micron thickness.
  • Application temperature: >15 ºC & <35 ºC.
  • Pot life of 5 L @ 25ºC: approx. 60 minutes
  • Mixed product density: 1.10 g/cm³
  • Mixed product viscosity: 3700 cP
  • Film (1 mm thick) set time @ 25°C: approx. 5 hours

Model Specification

abe.®cote vapour barrier a low viscosity epoxy resin is supplied by a.b.e.®. Installation is to be carried out by a trained applicator.

Cleaning of Equipment

Tools, brushes and mixing equipment must be cleaned immediately after use and before material has set with abe® super brush cleaner followed by washing with soap and water.


abe.®cote vapour barrier should be applied at temperatures between 15 ºC and 35 ºC. Temperatures should not fall below 5 ºC during the first 24 hours after application.


Available in 5 and 20 litres.

Storage and Shelf Life

Stored unopened in dry conditions at 5-25 ºC, shelf life will be 12 months minimum. Do not expose to frost.

Health & Safety

Product safety information required for safe use is not included. Before handling, read product and safety data sheets and container labels for safe use and physical and health hazard information. The safety data sheet is available from your local a.b.e.® sales representative.
