Performance Characteristics

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.
Very low permeability
  • Resistant to deicing salts, chloride, and chemical attack, and environmental pollution.
Breathability
  • Will not cause damage to structure by restricting moisture vapor flow.
Shaveable
  • Recreate sharp edges and architectural details.
Single component
  • Easy to batch in less than full pail quantities.
On-site color matching
  • Great matches, no wait for factory samples.

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 1/2 inch deep, of simple geometry, with no complex edge conditions.
  • Avoid long narrow repairs; these have a greater 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

Stone, Terracotta and Concrete
  • Prime the prepared substrate including all edges with a bond coat of Matrix. Work the bond coat into the substrate to ensure intimate contact and establish bond. The repair mortar must be applied into the plastic bond coat. If the bond coat dries, remove and re- apply.
Embedded Metal and Steel
  • Remove all scaling rust from embedded metal and steel.
  • Apply ECB anti-corrosion coating.

Mixing

  • Measure Matrix powder and water to achieve a 4 to 4.5 parts powder to 1 part water ratio (or approximately 1 gallon per 50 lb unit of Matrix).
  • Pour measured water into a clean container suitable for mixing.
  • Place 1/2 of measured Matrix into mixing container with water and mix until uniform. Add remaining 1/2 Matrix to the mixing container and mix until fully blended to a uniform, lump free consistency.
  • Mechanically mix using a low speed drill (400 – 600 rpm) and mixing paddle or mortar mixer.
  • Additional water may be added to achieve desired consistency for placement of the Matrix. Over watering the mix will affect final color.
  • For multiple batches, the additional water should be added in a uniform fashion to avoid color shift.
  • Insufficient water will not hydrate the material and it will not achieve full strength. Mix only as much material as can be placed in 15 – 20 minutes.
  • Do not over mix, as this will entrain excess air.
  • Do not re-temper, this will affect color.

Application

  • At the time of application, surfaces should be saturated surface dry/ damp (SSD) but hold no standing water.
  • Follow instructions for Priming.
  • Force the material against the edges of the repair, working from right to left or left to right.
  • Over-build repair zone by 1/4 inch.
  • Shave to final form with Mitre Rod up to 2 hours (longer in cold temperature) after application.
  • Do not overwork the finish.

Curing

  • Ensure repair zone stays properly hydrated. This may vary depending on ambient conditions. If hydration is not maintained, the repair may flash dry and not achieve full strength. Refer to ACI 308R-01 for detailed curing recommendations. If the repair is inaccessible, tape polyethylene over area to retain moisture. Do not allow polyethylene to contact the 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
  • 5 gallon plastic pails – 50 lbs.
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 24 hours.
  • Do not add more water than specified.
  • Do not re-temper, as this will affect color.
  • Avoid overworking material during placement as this will affect color and cause surface checking.
  • Do not allow polyethylene or burlene to touch surface while curing as this will cause whitening of the material.

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

First Aid

Stone repair mortars have lower compressive strengths compared to concrete mortars.  It is important that the repair mortar have similar physical properties to the stone being repaired.   Matrix is engineered to closely match the physical properties as well as the color and surface texture of these materials.      

The most obvious difference is our color program.  We have two facilities that perform color matching.  Our staff has over 100 years of combined experience matching stone.  We have Matrix tool kits which allow the trained applicator to perform color matching at the job site. We have the KIOSK Program which enables authorized dealers throughout the US to do color matching as well produce finished product in their stores.       

Yes.  Matrix VE (Viscosity Enhanced) has the same physical properties as regular Matrix but it is formulated to be fluid enough to be cast into molds.

Chatham Towers

Project History

Chatham Towers is a lower Manhattan landmark. Designed by Kelly and Gruzen, the dynamic twin 25-story buildings are a testament to the strong architectural styles of the 1960s. Previous repair work had failed. Large patches of unmatched mortar were clearly visible and gave the towers a mottled appearance. A primary concern, for both architect and contractor, was matching both the original color and pattern. The concrete had a pronounced wood grain texture with bug holes and voids. Howard L. Zimmerman Architects specified and pre-matched the color of the Matrix, M3P, and M3P Stain to the original concrete. Quality Building Contractors skillfully replicated the subtle patterns in the primary formwork. M3P and semi-transparent M3P Stain were chosen to blend and minimize the appearance of old and new repairs. The mineral silicate coatings both added subtle color uniformity without giving the towers a painted look. In addition, M3P and M3P Stain are effective water repellents and protect the structures from water damage and carbonation.

Dallas County Courthouse

Project History

The French chateau building that serves as the Dallas County Courthouse was constructed in 1902 and designed by two men, Willis T. Proudfoot and George W. Bird who had only one semester at the newly founded M.I.T. School of Architecture between them. Their primary guide was their extensive library of architectural books and drawings. When their firm was bankrupted by the Wichita building crash of the 1890s, they traveled in search of their fortune. Eventually, they settled in Iowa, where they built everything from funeral vaults to factories. The courthouse features a 128 foot tower, and is listed on the National Register of Historic Places. The firm of Keffer/Overton was commissioned to oversee both interior and exterior renovations. Exterior renovations presented a challenge. Natural Bedford Limestone features a variety of hues. Weathering caused the color variation to appear even more pronounced. E & H Restoration was able to tint Matrix repair mortar in the field to blend with each patch area.
