DUCOAT r 1000

Technical Data Sheet

DUCOAT R 1000 is an outstanding rubberized, thixotropic, anionic bitumen emulsion. The elastomeric property (due to 20% Rubber on dried film) of the liquid applied waterproofing membrane provides high flexibility and elasticity of the product to withstand high movements of the substrate due to changing temperatures. The product is thixotropic in nature that makes it ideal for protective coating applications on vertical structures.


  • Excellent polymer modified, liquid applied membrane.
  • Forms a tough, elastic and seamless coating upon drying.
  • Penetrates and seals porous substrate.
  • Resistant to dilute chemicals, chlorides and sulphates.
  • Non sagging and non-flowing at high service temperatures.
  • Water based no health hazard.
  • Resistant to high and low temperatures.
  • Excellent adhesion on damp and dry surfaces.

DUCOAT R 1000 is tested as the requirement of ASTM D 2939 and other relevant international standards.


Duproof is ISO 9001 Quality Assured Company, and DUCOAT R 1000 carries a material warranty against any manufacturing defects.


  • Protective coating for concrete and timber.
  • Various exposed roofs and built up roofs (concrete, cement, asphalt, lightweight screed or timber).
  • Concrete basements, footings, wet areas (bathrooms and kitchen).
  • Excellent vapor barrier for walls, floors and roofing structure.

METHOD OF APPLICATION(Substrate Preparation)

  • All substrate must be clean and free from dirt, dust, soil, grease, oil and other loose particles. Substrates that are very dry should be applied with a penetrative coating of DUPRIME E. If the concrete is very dry, dampen first with water.
  • Stir the emulsion thoroughly if stored for a long time.

Application System on Porous substrate (Concrete Structure)

  • Prime the surfaces with water based primer DUPRIME E and allow the primer to dry completely (6 – 8) hours.
  • Apply a minimum 2 coat by brush, roller or squeegee.
  • The second coat is applied when the first coat has completely dried.
  • Apply each coat at a right angle to the previous coat to achieve good coverage and uniformity.
  • A third coat is required for very porous substrate.
  • Drying time is 1–4 hours under normal conditions. Under damp and cold conditions it is recommended to allow 6 hours between successive coats.


DUCOAT R1000 is available in 20 liter pails and 200 liter drums, palletized and strapped. Store at temperature between 5oC and 50oC in a tightly sealed container. Shelf life is minimum of 1 year in a good storage protected from direct sunlight and frost.


There are no health hazards associated with DUCOAT R 1000, wash with copious amount of water if spilled on the skin.

The brush is cleaned using soap and water immediately after use. Brush is dipped in water before and during use for easy application. Place tools in water during breaks to prevent caking up of the bristles. A suitable solvent like white spirit, petrol or diesel oil removes dried emulsion.
