METHOD OF APPLICATION

Substrate Preparation

  1. All substrate must be clean, 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.
  2. Stir the emulsion thoroughly if stored for a long time.

Application System on Porous substrate (Concrete Structure)

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

Emulsified Bitumen is recommended to be applied at temperatures above 5°C.

PACKING AND STORAGE

DUCOAT 65 is available in 20 liter pails and 200 liter drums, palletized and strapped. Store at temperature between 5°C and 50°C in a tightly sealed container. Shelf life is minimum of 1 year in a good storage protected from direct sunlight and frost.
