The Application Process


1. Abrade

  • The substrate is abraded using the grit blasting technique.
  • The substrate is abraded to a surface preparation of 50-70 microns.
  • In this instance, micron refers to the texture of the surface and is the depth between the ridge and the valley.
  • OUTPUT: 400 sqm per day.

2. Clean

  • The substrate must be free on any dust, moisture or residue.
  • The cleaning is done through sweeping or high pressure air.

3. Prime

  • The primer may be applied with a roller or airless sprayer.
  • The airless sprayer is similar to the REACTOR but is not a plural component machine.
  • A metered clock (basic electronics) measures how much primer is applied.
  • The primer must be allowed to cure.
  • Concrete primers typically have a longer cure time due to the porous nature of concrete.
  • UV lights can speed the process.
  • Curing time is 4-6 hours but should be left no longer than 24hrs. If this is the case, the area will need to be re-primed.
  • OUTPUT: 1 hour of spray= 300sqm.

4. Spray

  • Module size determines the amount of chemical.
  • 438 nozzle is the most standard for spraying.
  • OUTPUT: max 6kg’s of chemical per minute on a 42/42 module.
  • 1 sqm = 1.16- 1.27 kg’s of mixed chemical.
  • The above equates to approx. 1kg per sqm per millimeter thickness.
  • 1 drum = 210 litres or 44 gallons.
  • 1 drum = 230 kg’s of resin.
  • 1 drum = 250 kg’s of isocyanate.
  • This equals approx 450-480 kg’s of chemical per mix.
