Primer

Primer is a long open time bonding agent used to improve adhesion between existing cementitious surfaces and new repair mortars/toppings.

Where to use:

Bonding primer for overlays and repair materials to hardened concrete.

How to apply:

Spray, roller, or brush applied. Additional Information

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.

Horizontal areas that are resurfaced are often exposed to the elements, particularly sun.  It can be difficult to maintain an SSD condition which can result in delamination. Primer has a 72 hour open time, eliminating the dry surface problem.          

Bonding primers are also beneficial when site conditions make SSD (Saturated Surface Dry) of vertical repairs difficult.

Projects Showcase

Audubon High School Grandstand

Project History

Audubon High School grandstand was built in 1936. Physical wear, corrosion of steel reinforcing, deicing salts, acid rain and freeze/thaw cycling all played a role  in spalling and deterioration of concrete surfaces.  The architect, structural engineer and school district formulated a repair strategy designed to restore the  structural elements, update the appearance and  incorporate protective measures to extend the useful  life of the stadium. Extensions to widen each of the steps  on the main stair aisles were poured to bring them up to  code. Conpro Primer was applied first to the existing  concrete to improve adhesion. Once the repairs were  complete Elastideck and Super Color Stain HR system  was used on the treads and risers to prevent water entry.  Color Coat was used to coat the soffit of the grandstand,  concrete columns supporting the grandstand and  the various knee walls around the grandstand.

 

Bryant University

Project History

Bryant University, founded in 1863, is one of the top business schools in the United States. Visitors are likely to be foreign dignitaries presenting lectures, busy executives taking advantage of Bryant’s development programs or recruiters from some of the nation’s top firms. The outdoor staircase leading into the Student Center exhibited signs of deterioration and was showing some exposed rebar and failing concrete, which needed to be repaired. The university had to work quickly to restore the campus’ professional appearance. The Waterproofing Company started by using bushhammers to get down to clean, sound concrete. Conpro Primer was used to provide a Velcro-like connection between the substrate and repair materials. Conpro Set was used to repair the vertical surfaces, while One Shot Ag was used to repair horizontal surfaces. Top Coat specially suited for areas facing pedestrian traffic provided a clean and skid-resistant finish, as well as added waterproofing protection.
