Primer

Performance Characteristics

• Single component No mixing, no waste.
• Long open time Apply up to 72 hours before placing covering material.
• Color trigger Pink when applied, turns orange when ready for covering material – about 30 minutes.
• Alkali trigger Alkalinity of cement causes material to react.
• Breathability Water vapor permeable.
• Non re-emulsifying Once cured will not be affected by water.
• Environmentally friendly Water based, low odor, non-flammable.
• Easy to use Spray with low pressure or airless sprayer.

Surface Preparation

• Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper penetration.
• Follow the specific surface preparation instruction for the Conproco material to be used.
• When placing fresh concrete expose aggregate of existing substrate a minimum of 1/8 inch (CSP 6). Refer to ICRI Surface Preparation Guide 03732 for information about Concrete Surface Profile (CSP).
• Protect adjacent areas from overspray.

Priming

• Conpro Primer is a priming treatment that is applied in a thin, uniform application.

Mixing

• Stir or shake container

Application

• Spray, roll, or brush Conpro Primer in a thin, uniform application.
• Do not allow Conpro Primer to form a surface film. It is critical to avoid excessive Conpro Primer thickness as this will result in a cohesive adhesion failure and delamination. On scarified horizontal applications, broom Conpro Primer immediately after spraying to avoid ponding. Conpro Primer is formulated to penetrate into the substrate.
• For roller applications use a 3/8 – 1/2 inch synthetic nap roller depending on texture of substrate.
• For spray applications use a low pressure or airless sprayer.
• Apply to all surfaces to receive covering material including the edges perpendicular to the repair zone.
• The material is pink when applied.
• The material will turn orange when dry – approximately 30 minutes @ 70°F and 50° RH.
• Apply covering material when Conpro Primer is orange.
• Install covering material within 72 hours.
• Re-apply Conpro Primer if more than 72 hours passes without placing covering material.

Curing

• No curing is required.

Clean Up

• Clean tools and equipment with water.

Coverage/Yield

• 150 – 200 ft.2/gal. depending on porosity of treated surface.
• Apply a test sample to determine actual coverage.

Product Handling

• Packaging 1 and 5 gallon containers
• Shelf Life 18 months in unopened containers.
• Storage Protect from freezing. Transport and store in cool, clean, dry conditions in unopened containers. High temperature will reduce shelf life.

Limitations

• Do not apply unless substrate and ambient temperature can be maintained at a minimum of 40°F for 8 hours. Refer to ACI Cold Weather Application Guidelines.
• Do not use Conpro Primer in lieu of proper surface preparation. Refer to ICRI Surface Preparation Guidelines for complete information.
• Contact Conproco for information on using Conpro Primer for DOT applications.
• Protect adjacent surfaces, Conpro Primer is pigmented and will discolor porous surfaces.
• Do not apply to frozen substrates.
• Do not apply on painted surfaces.
• Use caution when spraying in windy conditions.

Health and Safety

• Product is alkaline.
• Do not ingest.
• Avoid contact with eyes.
• Refer to Safety Data Sheet (SDS) for additional information.

First Aid

• In case of skin contact, wash thoroughly with soap and water.
• In case of eye contact, flush immediately with a high volume of water for at least 15 minutes and contact a medical professional.
• For respiratory problems, remove person to fresh air.
• If respiratory difficulty persists, contact a medical professional.

Disposal

• Dispose of material in accordance with local, state and federal regulations.
