Additional Information

Performance Characteristics

  • Anti-carbonation Reacts with calcium hydroxide, increases surface density.
  • Penetrating treatment Does not form a surface film or inhibit bond of subsequent materials such as coatings or repair mortars.
  • Environmentally friendly Water based, low odor, non-flammable.
  • Strengthen gain Increases compressive strengths of cement based materials.
  • Breathability Water vapor permeable.
  • Low viscosity Deep penetration.
  • Single component No mixing required.

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.
  • Protect glass from overspray.

Priming

  • Priming is not necessary.

Mixing

  • Stir or shake container.

Application

  • Always apply a test area to determine suitability of application.
  • 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.
  • Thoroughly saturate the surface to ensure adequate penetration.
  • For horizontal applications apply liberally and brush out to eliminate ponded material.
  • Additional coats can be applied when the previous treatment is dry-to-touch.

Curing

  • No curing procedures are required.
  • Allow 12 hours before repair mortar or coating is applied to treated surfaces.

Clean Up

  • Clean tools and equipment with water.
  • Clean windows with glass cleaner.

Coverage/Yield

  • 80 – 150 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.
  • Protect glass from overspray. Clean glass immediately with glass cleaner.
  • A white film can develop on dense surfaces or surfaces previously treated with water repellents. Clean immediately with acetic or other mild acid. After 24 – 48 hours it will be necessary to use mechanical abrasion to remove film.
  • The effectiveness will vary depending upon the porosity and chemical composition of the substrate. A test application should be performed to determine performance on a specific substrate.
  • Always apply a test sample on brick to determine any visibly undesirable effects, e.g. white crystalline film.
  • Do not allow material to pond.

  • 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.

Crumbling or soft mortar joints and punky concrete are frequently the result or freeze/thaw cycling, and environmental conditions. Treating the deteriorated surface with a consolidant can be an economical alternative to replacing the deteriorating material.        

Consolidants chemically react with calcium hydroxide resulting in a densification of the parent material.    They will permanently improve deteriorating cementitious surfaces.    The increase in density (lower porosity) provides an improved barrier to carbon dioxide, water and other contaminants.         

Start is a water-based environmentally friendly consolidant.

Lunt-Fontanne Theater

Project History

The historic beaux-arts style playhouse was built in the first decade of the last century and is the sole surviving theater designed by Carrere & Hastings. MIMIC was used to recreate the ornate frieze with panels, the cartouches and carved bearded heads. The cornice was replaced with GRC. Conpro Lastic was chosen for waterproofing and decorative finish.

University Plaza

Project History

The University Plaza Building, designed by noted architect Marcus T. Reynolds, was constructed between 1914 – 1918. The design of this building is a unique blend of traditional Gothic architecture with a modern reinforced concrete and steel frame. John G. Waite Associates used historic photographs to reconstruct the cast stone finials that had been removed during a 1970 renovation. The exterior façade is granite with cast stone door surrounds, copings, finials and pinnacles. Each block was examined to record a basis for repair or replacement. Many of the stones were cracked due to rusting elements or disintegrated from leaching of binders. Stone not replaced or repaired with dutchman was repaired with MIMIC, a cementitious stone repair mortar. The substrate was treated with Conpro Start, a consolident, to strengthen the cast stone. The exposed aggregate finish was reproduced by topically applying a special aggregate to the surface of the repair mortar.

 

 

Project History

Seneca Falls was named after a group of canals that run along side the Seneca River. Over the last decade, villages along the canals have been restoring historic structures, including the Arcade Building. The canal side concrete columns and beams had been deteriorated for many years. The contractor applied ECB, an anti-corrosion coating to the cleaned reinforced steel followed by a long open time bonding agent to the substrate. Multiple repair zones were prepared then overbuilt using Conpro Set, an overhead and vertical repair mortar. This was hand applied in several lifts and shaved to the original profile. A finish coat was applied to the entire surface for protection. The upper concrete beams had severe damage and the decision was made to encapsulate the substrate with Conpro One Coat, a stucco base that combines the scratch and brown coat in one application up to 1 – 2 inches thick, followed by a cementitious stucco finish. Conpro Shield W was applied to the entire structure to prevent water penetration.

First Presbyterian Church

Project History

First Presbyterian Church, an ICRI prize-winning project, showcased the Conproco approach to restoration. Cast stone elements that could be restored were saved using a combination of primers and repair mortars. These elements, along with replicated pieces, were coated with materials providing a uniform surface and carbon mitigation. Finally, a mineral silicate paint was used to prevent future staining and provide water repellency.
