M-METAL 800 - Metal Fairing Compound - Standard Cure

Is a high performance two pack solvent free Epoxy Fairing Compound and filler. The material is ideal for use on metallic surfaces and has been designed to be applied to manually prepared substrates.  

M-METAL 800 can be applied by trowel or stiff brush to large areas where excessive corrosion pitting is prevalent.

Once cured the product can be over coated with standard epoxy, acrylic and polyurethane coatings and paint systems.

Typical Uses

  • Filling Pitting on Corroded Tanks &  Structural Steel
  • As a Fairing Compound for Pipe Repairs

Application Guide

  • All oil and grease must be removed from the surface using an appropriate cleaner such 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.
  • 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:

  • Warm the base component is at a temperature between 15-25°C.
  • Ensure the ambient & surface temperature is above 5°C or less than 3°C above dew point.
  • Mix both Part-A and part-B together in full units as supplied. For small quantities us a mixing ratio of: 1:1 by volume or 1:1 by weight
  • When mixing both materials together, it is very important to have a uniform grey paste that is streak free.

Once mixing is complete, use all mixed material within 20-25 minutes at 20°C.

  • Apply the mixed material directly to the prepared surface as soon as possible after mixing. Using a short-bristled brush, spatula, squeegee or plastic applicator.

  • Minimum – the applied material can be over-coated as soon as it is touch dry.
  • Maximum – the over-coating time should not exceed 6 hours.

Where the maximum over-coating time is exceeded, the material should be allowed to harden before being abraded or flash blasted to remove surface contamination.
