• Apply to concrete or metallic surfaces
• Applied in 3 x coats
• Flexible finish
• Ideal for extreme impact environments

Typical applications

Chutes, Hoppers, Pumps, Valves and Pipe work

TECHNICAL SPECIFICATIONS

All Substrates Metallic Substrates

  1. All oil and grease must be removed from the surface using an appropriate cleaner such as MEK.
  2. All surfaces must be abrasive blasted to ISO 8501/4 Standard SA2.5 (SSPC SP10/ NACE 2) minimum blast
    profile of 75 microns (3mil) using an angular abrasive.
  3. Once blast cleaned, the surface must be degreased and cleaned using MEK or similar type material.
  4. All surfaces must be coated before gingering or oxidation occurs.

PLEASE NOTE: For salt contaminated surfaces the substrate must be pressure washed with clean water and checked
for salt contamination, please refer to the surface preparation and pre-application guide for further information.

Existing Concrete

  1. If the concrete surface is contaminated, pressure wash using clean water.
  2. Once the concrete is dry, lightly abrasive blast or scarify taking care not to expose the aggregate.
  3. Clean all dust and debris from the surface and prime with ProTXcoat 302 SPEP (low viscosity epoxy primer).
  4. Apply 503 SPEP at 150 microns (6mil) WFT, leave to cure for 3 hours (20°C/ 68°F) before overcoating.

New Concrete

  1. Allow new concrete to cure for a minimum of 21 days and treat to remove any surface laitance.
  2. Check the moisture content of the concrete prior to coating (8% moisture content or below).
  3. Lightly scarify the surface taking care not to expose the aggregate.
  4. Clean all dust and debris from the surface and prime with ProTXcoat 302 SPEP (low viscosity epoxy primer).
  5. Apply 503 SPEP at 150 microns (6mil) WFT, leave to cure for 3 hours (20°C/ 68°F) before overcoating.

Prior to mixing please ensure the following:

  1. The base component is at a temperature between 15-25°C (60-77F°).
  2. The ambient & surface temperature is above 10°C (50F°).
  3. The ambient & surface temperatures are not less than 3°C (6°F) above the dew point.

Once these 3 checks have been met, please proceed with mixing the product.

  1. Transfer the contents of the Activator unit into the Base container.
  2. Using an electric paddle mixer, mix the 2 components until a uniform material free of any streaks is achieved.
  3. From the commencement of mixing the whole of the material should be used within 20 minutes at 20°C (68°F).

Brush or roller applications

  1. Pour the mixed material into a paint kettle or paint tray (this will maximise the usable life)
  2. Using a 50mm (2”) wide synthetic brush, stripe coat all edges, joints, corners and equipment with the mixed
    material. The stripe coat must be approximately 100mm (4”) wide, at 300 microns (12mil) wet film thickness.
  3. Once the stripe coat has cured sufficiently and is capable of being overcoated, apply the 1st coat of mixed product
    to all surfaces at 300-400 microns (12-16mil) wet film thickness.
  4. Once the 1st coat of material has cured sufficiently, approximately 6-8 hours at 20°C (68F°), apply a 2nd coat of
    material to all surfaces at 300-400 microns (12-16mil) wet film thickness.
  5. Once the 2nd coat of material has cured sufficiently, approximately 6-8 hours at 20°C (68F°), apply a 3rd coat of
    material to all surfaces at 300-400 microns (12-16mil) wet film thickness.
Coverage Rates
1ltr (0.3 US gallon) of fully mixed product will give the following coverage rates:2.5m2 at 400 microns26.88ft2 at 16mil
Please note that the coverage rates quoted are theoretical and do not take into consideration the profile or condition of the surface being repaired.
Cure TimesAt 20°C (68F°) the applied materials should be allowed to harden for the times indicated below before being subjected to the
conditions indicated. These times will be extended at lower temperatures and reduced at higher temperatures:
