ISR CM

ISR CM (Color Matched) is for aesthetic concrete repairs. It is designed for restoring concrete structures while preserving their original appearance.

Where to use:

Protective repairs to vertical and overhead surfaces that match the color of the parent concrete.

How to apply:

Trowel applied. Additional Information

Performance Characteristics

Sustainable Green Technology
  • Contains significant concentrations of both pre-and post-consumer recycled content.
Low Shrinkage
  • Maintains integrity of repair, resists cracking.
Thermal Compatibility
  • Prevents delamination due to temperature change.
Durable
  • Resistant to weathering action, excellent freeze/thaw stability and abrasion resistance.
Long-term Protection
  • Resistant to deicing salts, carbonation, chloride, and chemical attack.
Dimensionally Stable
  • Suitable for large areas.
Extensive color spectrum
  • Available in 23 standard colors and custom color matching.

Surface Preparation

  • Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper bond.
  • Saw cut edges with a diamond blade at a 90° angle to eliminate feather edging. Avoid polishing the edges as this will inhibit bond.
  • Avoid bruising or micro cracking during surface preparation. Refer to ICRI Surface Preparation Guide 03732.
  • Repair zone must be a minimum of 1 inch deep, of simple geometry, with no complex edge conditions.
  • Avoid long narrow repairs; these have a tendency to crack.
  • Saturate substrate with clean water, (saturated surface dry/SSD), with no standing water during application.
  • Remove concrete from corroded steel and several inches beyond to expose non-corroded steel.
  • Provide a 3/4-inch clearance between the concrete and steel.
  • Damaged reinforcing steel should be inspected by a qualified engineer and appropriate action taken.

Priming

  • Prime the prepared substrate including all edges with a bond coat of ISR CM. Work the bond coat into the substrate to ensure intimate contact and establish bond. ISR CM must be applied while bond coat is wet. If the bond coat dries, remove and reapply.
Embedded Metal and Steel
  • Remove all scaling rust from embedded metal and steel. Apply ECB anti-corrosion coating.

Mixing

  • Mechanically mix using a low speed drill (400-600 rpm) and mixing paddle or mortar mixer.
  • Pour 2 1/2 quarts of potable water into a clean mixing vessel and slowly add all of the powder (4 to 4-1/2:1powder to water ratio).
  • Mix continuously for 3 minutes to a uniform, lump-free consistency.
  • Add up to 1 cup of additional water, if needed.
  • Allow to “breathe” for 1 minute and remix for 1 minute. This will improve workability and extend open time.
  • Mix only as much material as can be placed in 15 – 20 minutes.
  • Do not overmix, this will entrain excess air.
  • Do not retemper, this can affect color.

Application

  • At the time of application, surfaces should be saturated surface dry (SSD) but hold no standing water.
  • Follow instructions for Priming.
  • Force the material against the edges of the repair, working toward the center.
  • Material may be applied in multiple lifts of not less than 1 inch and no greater than 2 inches.
  • Consolidate each lift and allow to stiffen to thumb-print hard before continuing.
  • Scratch (screed/open pores) each lift to prepare surface for subsequent lift.
  • Repairs 2 inches or greater may be filled with ISR VO or ISR AG to within 1 inch of surface. Minimum depth of ISR CM is 1 inch.
  • Over-build ISR CM final lift by 1/4 inch.
  • Shave to final form with trowel edge up to 2 hours after application.
  • Do not overwork the finish.
  • Finishing techniques and the length of time the material has cured when shaved will have a significant effect on the appearance of the color and degree of texture.

Curing

  • Keep repair zone damp for 24  hours. Refer to ACI 308R-01 for detailed curing recommendations. If repair is inaccessible, tape polyethylene over area to retain moisture. Do not allow polyethylene to contact material.
  • Protect repair from direct sunlight, wind, rain and frost during curing period.

Clean Up

  • Clean tools and equipment with water immediately after use.
  • Cured material must be removed mechanically.

Product Handling

Packaging
  • 50 lb. plastic pails
Shelf Life
  • 18 months when properly stored.
Storage
  • Transport and store in cool, clean, dry conditions in unopened containers.
  • High temperature or high humidity will reduce shelf life.

Limitations

  • Do not apply unless substrate  and ambient temperature can be maintained at a minimum of 40°F for 24 hours. Refer to ACI Cold Weather Application Guidelines.
  • Cold mixing water and low temperature will retard set. Hot water and high temperature will accelerate set.
  • Protect application from precipitation and high wind for at least 8 hours.
  • Do not add more water than specified, this will lower strengths, induce shrinkage cracking and alter final color.
  • Avoid overworking material during placement and finishing – this will affect color and produce surface (map) cracking.
  • Do not allow polyethylene or burlene to touch surface while curing as this will cause whitening of the material.

Health and Safety

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

First Aid

  • In case of skin contact, wash thoroughly with soap and water.
  • For 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.

Post World War II concrete structures are of an age that often requires repair and restoration. Most repair mortars are a noticeably different color from the parent concrete.   The repairs create a patchwork appearance which detracts from the overall aesthetic of the structure. Painting the structure to hide the patches is generally not an acceptable option.            

ISR CM, is a repair mortar specifically designed to match the color and texture of concrete substrates.  ISR CM provides a repair that is more natural in appearance and sympathetic to the structure. ISR CM (Color Matched) preserves the original aesthetic while eliminating the cost and maintenance issues associated with painting.  

The ISR System provides color matched concrete repairs. When installed it is cost competitive with general repair mortars. ISR CM is part of a system of ISR products.  Both ISR VO and ISR AG are compatible as fill materials for deep repairs.

ISR CM is available in 23 standard colors, at Conproco dealers and Conproco Kiosk Dealers. Custom colors are available through Conproco's two color matching facilities.             

A KIOSK dealer has the ability to do color matching at the store. They can provide quick turnaround of color samples as well as producing pails of finished product.
