METHOD OF APPLICATION(Substrate Preparation)

  1. All substrates must be clean and sound, 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.
  2. Stir the solution prior to use thoroughly if stored for a long time.

Application System on Porous substrate (Concrete Structure)

  1. Apply minimum 2 coats by brush or spray equipment.
  2. The second coat is applied when the first coat has completely dried.
  3. Apply each coat at a right angle to the previous coat to achieve good coverage and uniformity.
  4. A third coat is required for very porous substrate.
  5. Drying time is 4-6 hours under normal conditions.

Application System on Metal Structures

  1. Clean the substrate by removing rust, scale and dirt using wire brush. Wipe off traces of oil and grease with a suitable solvent.
  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. Drying time is 4-6 hours under normal conditions.
