ALDOPRIME 624 is a fast drying rust inhibiting primer designed also as a tie coat for dusty or porous surfaces to improve adhesion of the base coat products. It has been formulated to have exceptional adhesion to a diversity of substrates and penetrates into the surface and provides good anchorage for base coat product in addition to inhibiting rust on oxidized surfaces. Once the finish coat has been applied, ALDOPRIME 624 enhances the properties of topcoat and provides increased resistance to mechanical damage and chemical attack.

Application Method
Uses
  • ALDOPRIME 624 was specially formulated as a primer coat for rusted metal panels, weathered surfaces or porous materials.
  • ALDOPRIME 624 has an excellent adhesion to a variety of substrates, such as metal, BUR, asphalt, wood, concrete, masonry and polyurethane foam.
  • When used as a black product, ALDOPRIME 624 has been used as an insulator coat for warming roof surfaces before applying sprayed in place polyurethane foam or coating basecoat.
  • Due to low solids and low dry mil thickness, ALDOPRIME 624 is not recommended as a coating product in itself. Apply base coat as soon as possible after primer cures.
Application Instructions
  • ALDOPRIME 624 may be applied by medium nap rollers or airless spray equipment.
  • Apply ALDOPRIME 624 only to clean, dry, sound surfaces free of loose particles or other foreign matter. Power washing is recommended on all surfaces prior to application.
  • Apply ALDOPRIME 624 at the rate of 3/4 - 1.0 gallons per 100 square feet of roof surface.
  • Normal drying time is 1 - 2 hours.
