Drying Times


Drying Times At 20°C
Touch Dry: 4 hours
Hard Dry: 24 hours

  • Allow hard dry prior to sanding
  • HMG technical data sheets (see section above) indicate a dry film thickness that will be achieved when applying a particular wet film thickness
  • These values are a guide only and are not to be used as specifications
  • Film thickness will vary depending on actual use and specification
  • Great care should be taken to achieve the dft stated in the agreed specification and to avoid areas of excessively low or high thickness

 

Surface Preparation


  • Ensure surfaces are clean, dry and free from grease, oils, dust and other contamination prior to application
  • Read and follow the safety data sheet, product data sheet (see section above) and label instructions
  • Thoroughly clean and degrease using suitable HMG Prep Clean 2802, 2803 or 2804
  • Rust/corrosion to be removed to Sa or St standards, remove to clean metallic appearance with little or no
    rust/corrosion present
  • Areas where blast cleaning is not cost effective or practical, then the use of HMG Ferrozinc Rust Converter is an alternative
  • Though HMG Ferrozinc is not an equivalent alternative to shot blasting, it does offer a far superior performance than conventional coatings applied to slightly rusted surfaces
  • HMG Ferrozinc is used after simple wire brushing to remove surface rust, prior to application of primer
  • Stir all paints thoroughly before use
  • Always use the same batch number on the same job
  • Check colour & sheen
  • Filter the product immediately before use
  • Reduce emissions and maintain quality by replacing tin lid after use.
