Performance Characteristics

  • Low shrinkage Maintains integrity of repair, resists cracking.
  • Thermal compatibility Prevents delamination due to temperature change.
  • Corrosion protection Protects reinforcing steel in repair zone and suppresses ring anode effect.
  • Durable Resistant to weathering action, excellent freeze/thaw stability and abrasion resistance.
  • Very low permeability Resistant to deicing salts, carbo- nation, chloride, and chemical attack.
  • High build Place up to 2 inch lifts without rebound.
  • Economical Improves productivity.
  • Consistent results Excellent consolidation around reinforcing steel.
  • High early strength Minimize out-of-service time.

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 1/4 inch deep, of simple geometry, with no complex edge conditions.
  • Avoid long narrow repairs; these have a tendency to crack.
  • Apply Conpro Start where a consolidant is of benefit.
  • Saturate substrate with clean water, (saturated surface dry/SSD), with no standing water during Priming or 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

Concrete
  • Apply Conpro Primer, or ECB as a bonding primer to all exposed surfaces. Refer to the individual product technical data bulletin for information.
Reinforcing Steel
  • Remove all scaling rust from reinforcing steel.
  • Apply ECB anti-corrosion coating.

Mixing

  • Mechanically mix using a low speed drill (400-600 rpm) and mixing paddle or mortar mixer.
  • Pour 2-1/4 quarts of potable water into a clean mixing vessel and slowly add all of the powder.
  • Mix continuously for 3 minutes to a uniform, lump-free consistency.
  • Add up to 1 pint of additional water, if needed.
  • Allow to “breathe” for 1 minute and remix for 1 minute. This will improve workability and open time.
  • Do not overmix, as this will entrain excess air.
  • Do not re-temper.

Application

  • At the time of application, surfaces should be saturated surface dry (SSD) but hold no standing water.
  • Follow instructions for Priming.
Spray Application
  • Material should be applied by an experienced nozzle man using a rotor/stator or peristaltic pump.
  • Follow ACI 506R,for recommendations for wet process shotcrete.
  • Material may be applied in multiple lifts of not less than 3/8 inch and no greater than 2 inches.
  • Allow material to stiffen to thumb-print hard before continuing.
  • Scratch (cross-hatch) each lift to prepare surface for subsequent lift.
  • Strike off with straight edge to a uniform plane, close with a trowel or sponge float.
Trowel Application
  • Force the material against the edges of the repair, working toward the center.
  • Material may be applied in multiple lifts of not less than 3/8 inch and no greater than 2 inches.
  • Consolidate each lift and allow to stiffen to thumb-print hard before continuing.
  • Scratch (cross-hatch) each lift to prepare surface for subsequent lift.
  • Finish with a sponge float or trowel.
  • Do not overwork the finish.

Curing

  • Dampen the repair with a fine mist of water for 24 hours or moist cure with wet burlap and polyethylene. Alternatively, apply ProMasonry Cure & Seal.
  • 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.

Coverage/Yield

  • 0.41 ft³/50 lbs.

Product Handling

  • Packaging 50 lb paper bags.
  • Shelf Life 12 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 and cause shrinkage cracking.
  • Avoid overworking material during placement and finishing – this will produce surface (map) cracking.

Gunshot LPS is a fiber-reinforced mortar formulated to be applied with low pressure spray equipment. Low pressure spray is much more efficient than hand patching when placing large repairs.  It is also well suited for repair zones that are congested with rebar.

Gunshot LPS can be sprayed through most carousel and rotor stator pumps.        

Strike off with a straight edge to a uniform plane, close with a trowel or sponge float.     

Yes.  The ability to use as a spray or hand applied material reduces the number of products on a job.

Winchester Arms

Project History

Winchester Repeating Arms Company, famous for manufacturing the “Gun that Won the West,” set up shop in downtown New Haven, CT in 1847. Business boomed and by the 1870s, “Winchester” was famous the world over for quality, service and craftsmanship. In 1988, the Winchester Repeating Arms Company Historic District was listed on the National Register of Historic Places. Its New Haven plant closed in 2006 and factory spaces fell into disrepair until developers made plans to transform the dilapidated building complex into one of New Haven’s newest neighborhoods, Winchester Lofts.
The interior was completely gutted and the spalled, deteriorated concrete on the floor slabs, beams, columns and window openings was repaired. Conpro Set was used for hand applied repairs. Forment ® was selected for larger areas where forming and pouring is more practical and cost-effective.
The exterior concrete columns and spandrels were repaired using ECB rebar coating and Gunshot LPS then coated with Conpro Lastic. The original brick infills were partially demolished to allow for larger windows. The remaining brick areas under the window sill and above the spandule beam were refaced with Structural Skin ® to stabilize, strengthen and fill voids from deteriorating mortar joint and then coated with Conpro Lastic to further protect and waterproof it.
Ultimately this system was more cost effective than repointing and provided a cleaner, more contemporary monolithic appearance the architect was looking for.

 

Loom City Lofts

Project History

In 1906, the wool producing Minterburn Mill, was one of the first structures in New England constructed entirely with reinforced concrete technology. The building was purchased in 1968 by sweater manufacturer Roosevelt Mills. The company, with sales offices in New York City, became an industry leader and innovator and at its peak, sold 12,000 sweaters a week to major retail chains like J.C. Penny and Montgomery Ward. The business and building were sold to new owners in 1986 and closed just two years later. The nearly 100-year-old building which is on the National Register of Historic Places remained vacant until its purchase in 2002.
New owners laid plans to convert it into an industrial-themed apartment building. The scope of work approved for the building and smokestack by architect James K. Grant Associates and carried out by Armani Restoration, included a three step process using a system of repair and protection products from Conproco, formulated specifically for the intended application method and desired outcome. The goal was to first arrest rebar corrosion with ECB, a single component, zinc-rich acrylic primer. Second, repair severe concrete deterioration inside and out with both Gunshot LPS, a spray or trowel-on mortar and Forment®, a high-flow pumped or poured repair mortar. And finally, apply Conpro Lastic, a durable, breathable, opaque and aesthetically pleasing, flexible, waterproof, anti-carbonation coating to provide additional protection.
The Connecticut Trust for Historic Preservation presented Loom City Lofts with an Award of Merit for its efforts in historic preservation in April 2016.
