Description

M-CORR 500 - Water-Based Acrylic Encapsulation Coating

Is formulated to provide long-term protection to steel structures, concrete surfaces or surfaces with existing coatings. Due to the nature of the product, it can be applied to the hydro-blasted or manually prepared surfaces and offers a typical life expectancy of in excess ten years.

Typical Uses

  • Concrete structures
  • Structural steel
  • Storage tanks
  • External pipe protection
  • External tank coating
  • Structural steel protection

Please contact us to discuss your project before purchasing this material to confirm suitability.

Application Guide

  • All surfaces must be hydro-blasted using clean water at 12,000 psi (850bar) to NACE 5 (SSPC SP13 WJ3-WJ1).
  • All surfaces must be coated before gingering or oxidation occurs
  • 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.

Existing Concrete

  • If the concrete surface is contaminated, pressure wash using clean water.
  • Once the concrete is dry lightly abrasive blast or scarify taking care not to expose the aggregate.
  • Clean all dust and debris from the surface and take several moisture readings and prime with M-PRIME 100 – Low Viscosity Epoxy Concrete Primer or M-PRIME 104 – Damp Tolerant Concrete Primer dependent on the moisture readings obtained.
  • Apply M-PRIME 100 or M-PRIME 104 at a target wet film of 150 microns, allow to cure before overcoating.
  • For very porous surfaces a second coat of primer may be required.

New Concrete

  • Allow new concrete to cure for a minimum of 21 days, lightly abrasive blast or scarify to remove any surface laitance.
  • Clean all dust and debris from the surface and take several moisture readings and prime with M-PRIME 100 – Low Viscosity Epoxy Concrete Primer or M-PRIME 104 – Damp Tolerant Concrete Primer dependent on the moisture readings obtained.
  • Apply M-PRIME 100 or M-PRIME 104 at a target wet film of 150 microns, allow to cure before overcoating.

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.
  • Using a low speed electric paddle mixer, ensure a consistent mix of acrylic emulsion is achieved.
  • Once mixing is complete use the mixed paste as soon possible.
  • Use all mixed material within 20-25 minutes at 20°C.

Brush & 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 and is capable of being overcoated, apply a basecoat at a minimum wet film thickness 400 microns.
  • Once the basecoat has cured sufficiently, approximately 30 minutes at 20°C, apply a topcoat at a minimum wet film thickness of 400 microns.
