M-PRIME 200 – Aluminium Based Primer

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

1. All surfaces must be hydro-blasted using clean water at 12,000 psi (850bar) to NACE 5 (SSPC SP13 WJ3-WJ1).

• All oil and grease must be removed from the surface using an appropriate cleaner such as MEK.
• All surfaces must be mechanically abraded using handheld grinders to ISO 8501/4 ST3 (SSPC SP3 ST3).
• Once abraded the surface must be degreased and cleaned using MEK or similar type material.
• All surfaces must be repaired before gingering or oxidation occurs.

Prior to mixing please ensure the following:

• The base component is at a temperature between 15-25°C.
• Do not apply the material when the ambient or substrate temperature is below 5°C.

• Transfer the contents of the Activator unit into the Base container.
• Using a low speed electric paddle mixer, mix the 2 components until a uniform material free of any streaks is achieved.
• Once mixing is complete, use the mixed primer as soon possible after mixing.

Use all mixed material within 20 minutes at 20°C.

Brush or roller

• Pour the mixed material into a paint kettle or paint tray (this will maximise the usable life).
• Stripe coat all edges, joints & corners.
• Once the stripe coat has cured sufficiently apply a basecoat to all surfaces at 150 microns wet film thickness.
• Under normal circumstance 1 coat should be acceptable if the primer is used in conjunction with Epoxy or Polyurethane intermediate and topcoats.
• If a second coat is required allow the basecoat to cure for approximately 6 hours at 20°C.
• Apply a second coat to all surfaces at 150 microns wet film thickness.
