Heavy Duty Bitumen Coating, Vapour Barrier & Flooring System Binder

Thixotropic water dispersed bitumen emulsion.


flintkote 3 is a general purpose bituminous coating and vapour barrier and flooring system binder. See abe.®co mastic and tank base mastic.

  • Waterproof coating and vapour barrier.
  • Easy to apply and cost effective.
  • Waterproof binder for mastic flooring which is easily repairable.
  • Suitable for waterproofing membrane (with fabric and UV protection).
  • Potable water containment.

Surface Preparation

Steel – must never be coated directly with flintkote 3.

abe® bitu.®prime should be used as a first coat and preparation of the steel must be as specified for the primer. Galvanised steel – must be free of oil, grease and anti-white rust treatment. Scrub the surface thoroughly with a paste made from abe® super brush cleaner and an abrasive soap. This may be applied with a cleaning pad (e.g. Scotchbrite). Thoroughly wash away all residues using clean water.

Concrete and other porous surfaces must be free of all dust and laitance. The first coat of flintkote 3 should be diluted 1:1 with clean water.  See data sheet.

Bonding / Priming

Dilute 1:1 with water for porous surfaces. Application rate 6.7 m2/L.
The coverage rate may change subject to the surface texture and absorption properties. Use bitu.® prime on steel.


Stir flintkote 3 well before use, using a flat paddle.


1,25 m2/l as coating;

7 l/m2 as binder.


flintkote 3 is normally applied by brush and generally should not be applied thicker than specified. The first coat should be thoroughly dry before application of a second coat. This can be easily determined by rubbing the surface with a wet finger. If the finger remains clean, the surface is dry enough to overcoat. flintkote 3 can be used in conjunction with a glass fibre membrane to build up and reinforce thicker coats. The membrane must be set into the still wet film of flintkote 3 and ideally all bubbles and wrinkles should be removed by means of a laminating roller. The film is allowed to dry and then a second coat is applied at a sufficient thickness to completely obliterate the weave and pattern of the membrane.

Where the flintkote 3 film is finally to be exposed to the effects of sunlight and ultra-violet radiation, it is recommended that, some 3 – 4 weeks after being applied, it be overcoated with abe® silvakote.

Protection on Completion

Protect against traffic and spillage until cured. If exposed to direct extensive sunlight, overcoat with abe® silvakote.


Ordinary clean water or abe.® super brush cleaner.

Temperature and Relative Humidity

High humidity slows evaporation of water dispersant.

Model Specification

Water dispersed single-component, general purpose bitumen emulsion supplied by a.b.e.® Construction Chemicals, installed to manufacturer’s instructions.


5 L, 25 L and 200 L yield metal containers.

Handling & Storage

Flintkote 3 has a shelf life of 12 months if kept in a dry, cool place in the original, unopened container. If stored at high temperatures and/or high humidity conditions, the shelf life may be reduced.

Health & Safety

flintkote 3 is mildly toxic and non-flammable. Ensure the working area is well ventilated during application and drying. Avoid inhalation of dust and contact with skin and eyes. Suitable protective clothing, gloves, eye protection and respiratory protective equipment should be worn. The use of barrier creams provides additional skin protection. If contact with skin occurs, wash with water and soap. Splashes into eyes should be washed immediately with plenty of clean water and medical advice sought.

Cured flintkote 3 is inert and harmless.
