Product Highlights

ConoPrime No. 502 is specifically formulated to easily penetrate concrete substrates. It is recommended to ensure maximum adhesion where conventional primers may not penetrate. This primer is an integral part of the lining in that it helps seal porous substrates and promotes adhesion of the protective material. No. 502 helps reduce offgassing from concrete. It offers easy application properties to reduce total down time.

Characteristics
  • Promotes tenacious adhesion of Sauereisen No. 381 and No. 309
  • Easy to apply - spray, brush or roll
  • High bond strength
  • Excellent moisture tolerance

Area Preparation

Temperature of Working Area

  • Maintain a temperature of 50°- 90°F on air, substrate, Liquid, and Hardener components during mixing, application, and cure for optimum results. The material components should be maintained at 50°F to 80°F for 48 hours prior to beginning work. Ambient temperature must be at least 5°F above dew point.
  • Application in direct sunlight and rising surface temperatures may result in blistering of materials due to expansion of entrapped air or moisture in the substrate. Concrete that has been in direct sunlight must be shaded 24 hours prior to application and remain shaded until after the initial set of the topcoat. When the surface temperatures are rising, it may be necessary to postpone the application or apply during declining temperatures.

Surface Preparation

  • Concrete - Refer to SSPC-SP13/NACE 6 "Surface Preparation of concrete" for detailed guidelines.
  • New Concrete - All structures must have the necessary strength to withstand imposed loads during normal use and operation. After ConoPrime No. 502 is applied, the surfaces should be floated with Sauereisen Urethane Filler Compound No. 309 to fill all voids and depressions.
  • Substrates must be free of oil, grease, and other contaminants that may inhibit bond. This can be achieved by chemical cleaning. Abrasive blast, or high-pressure water blast to remove laitance and to obtain a uniform surface texture exposing fine aggregate resembling coarse sandpaper.
  • Old Concrete - Concrete must be dry, firm and must have the necessary strength to withstand imposed loads during normal use and operation.
  • Surfaces must be free of oil, grease, and other contaminants that may inhibit bond. This can be achieved by chemical cleaning. Mechanical methods should be utilized to remove laitance, old paints, protective coatings, and attacked or deteriorated concrete.
  • For concrete substrates, abrasive blast or high-pressure water blast to obtain a clean, uniform, and sound substrate. All structural cracks should be repaired. All slopes should be reestablished.
  • Brick - Surfaces must be free of oil, grease, and other contaminants that may inhibit bond. This can be achieved by chemical cleaning. Abrasive blast or highpressure water blast all foreign particles and attacked or unsound mortar from the joints. Loose brickwork should be regrouted with appropriate Sauereisen mortar to ensure structural integrity. Mortar joints should be repointed to be flush with the face of the masonry units.
  • When chemical cleaning, abrasive or high-pressure water blasting is used as the method of surface preparation, all sand and/or debris must be removed by thoroughly vacuuming the area with an industrial vacuum cleaner.
  • If surfaces do not meet desired conditions, repeat surface preparation procedures.
Application

Mixing

  • Premix the Part A and Part B seperately before combining. Primer is packaged in premeasured containers consisting of Hardener Part A, and Resin Part B, which must be mixed together before use.
  • Completely empty contents of Hardener Part A into Resin Part B container. Using a slow speed 1/2 inch drill motor with a "Jiffy" type blade, mix thoroughly for three minutes until blended to uniform consistency. Primer is ready for use immediately after mixing.
