Features

  • Biodegradable
  • Emulsifies oils
  • Contains no solvents, phosphates, halogens, or petroleum distillates
  • Dramatically improves aged overcoatability, saving on costs for secondary surface preparation
  • Freezing point: 25°F (-4°C)
  • Boiling Point: 212°F (100°C)
  • Flash Point: none
  • pH 11.5 - 13.0
  • Coverage: 1 gallon (diluted 2 parts water to 1 part concentrate) will treat between 1,000 - 1,500 square feet, depending on the configuration of the substrate and application losses

Recommended Substrate Conditions and Temperatures

  • Ambient temperature should be between 40°F (5°C) and 100°F (37°C)
  • Material temperature should be between 40°F (5°C) and 90°F (32°C)
  • Surface temperature should be between 40°F (50°C) and 100°F (37°C) (pre-cool the surface by water rinsing prior to application of Prep 88 if required)

Instructions for Use

  1. Shield any surfaces not intended to be treated.
  2. Wear appropriate eye protection and avoid contact with skin.
  3. Pre-clean any heavy residues by power washing.
  4. If steel temperatures exceed 100°F (37°C), pre-cool the steel by water washing to prevent Prep 88 from drying on the surface prematurely. Do not apply under freezing conditions.
  5. Mix Prep 88 with fresh, clean water according to the instructions below:
    • Light Cleaning (no visable contaminants): 3 parts water to 1 part concentrate
    • General Cleaning and restoring overcoatability: 2 parts water to 1 part concentrate
    • Heavy soiling, greasy residues: 100% concentrate
  6. Prep 88 can be applied with a low pressure sprayer (garden sprayer, etc.), brush, or roller.
  7. Apply generously to the surface, ensuring all areas are thoroughly wetted. Caution should be used on complex structures to ensure Prep 88 can be applied to all areas and subsequently rinsed.
  8. Scrub with a nylon brush as needed for cleaning heavy residues.
  9. Allow Prep 88 to dwell on the surface for the following times based on the surface temperatures:
    • 40°F: 20 - 30 minutes
    • 70°F: 10 - 20 minutes
    • 90°F: 10 - 15 minutes
    • 100°F: 5 - 10 minutes
    • Do not allow Prep 88 to dry on the surface. If product does dry on the surface, a second application of Prep 88 will be required to dissolve the dried residue.
  10. Power wash the surface to thoroughly rinse all traces of Prep 88 from the surface. Ensure the surface pH has been neutralized (7.5 maximum). Failing to remove Prep 88 from the surface will be detrimental to the performance of successive coats.
  11. Allow the surface to dry thoroughly prior to overcoating.
  12. Protect surfaces from contamination prior to overcoating. Apply coatings within the following timeframe of Prep 88 application:
    • 40°F - 50°F: 48 hours
    • 51°F - 70°F: 36 hours
    • 71°F - 90°F: 32 hours
    • 90°F: 24 hours
