Matrix TR

Matrix TR is formulated to provide long-term protection of natural stone and concrete when full-depth repairs are unnecessary or not practical.

Where to use:

Thin, protective repairs to brownstone, sandstone, limestone, cast stone, terracotta, and concrete.

How to apply:

Brush or trowel applied. Additional Information

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, carbonation, chloride, and chemical attack.
  • Breathability Will not cause damage to structure by restricting moisture vapor flow.
  • Complete kit Pre-measured, two component system in one container.
  • Extensive color spectrum Available in 11 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.
  • Apply Conpro Start where a consolidant is of benefit.
  • Pre-treat static cracks and voids with Injection Grout where applicable.
  • Saturate substrate with clean water, (saturated surface dry/SSD).
  • Mechanically prepare surface to be open-pored and textured (CSP 3). Refer to ICRI Surface Preparation Guide 03732 for information about surface preparation.

Priming

  • No priming is required under normal circumstances.

Mixing

  • Mechanically mix using a low speed drill (400-600 rpm) and mixing paddle.
  • Thoroughly shake K-88 Admix to disperse the pigment.
  • Mix 3 parts powder to 1 part K-88 Admix.
  • Mix continuously for 3 minutes to a uniform, lump-free consistency.
  • 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.
  • Apply material with a stiff bristle brush or trowel.
  • Work material into substrate to promote proper adhesion.
  • Coat individual stones (not continuous over mortar joints) a maximum thickness of 1/16 inch.
  • Finish with either a sponge float or trowel.
  • Do not overwork the finish.

Curing

  • Protect repair from direct sunlight, wind, rain condensation and frost during curing period.

Clean Up

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

Coverage/Yield

  • 10 lb. kit – 20 ft² @ 1/16 inch.

Product Handling

  • Packaging 10 lb. kit contains 8.36 lbs. of powder and 2.1 lbs. of K-88 Admix in 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. Protect K-88 Admix from freezing.

Limitations

  • Do not apply unless substrate and ambient temperature can be maintained at a minimum of 50°F for 24 hours. Refer to ACI Cold Weather Application Guidelines.
  • Protect application from precipitation condensation and high wind for at least 24 hours.
  • Do not re-temper, polymer modified materials.
  • Avoid overworking material during placement.
  • Do not apply curing compounds.
  • 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.

Disposal

  • Dispose of material in accordance with local, state and federal regulations.

Sills, lintels, terracotta and scaling are examples of areas that can require repair, but full depth repairs are not practical. With Matrix TR the repair process is limited to application of a coating engineered to be compatible with masonry surfaces.        

Matrix TR is a two-component cementitious coating that can be applied to damaged surfaces.  This durable protective layer prevents further deterioration from water and environmental contaminants. Matrix TR is available in 11 standard colors.

Add Color K-88 to the Matrix TR powder. Mix with mechanical mixer @ 400 - 600 rpm for 3 minutes. Apply with stiff bristle brush or trowel up to 1/16".  Finish with either sponge float of trowel.  Do not over work finish.

Birmingham City Hall

Project History

Birmingham City Hall was designed by noted Michigan architect Marcus Robinson Burrowes. Deicing salts caused the deterioration of existing limestone at the foundation, the marred perimeter stones were at eye-level height and obvious to pedestrians. Some stones required substantial restoration and others only minor surface treatment. Furthermore, the limestone had a bush hammer texture that needed to be recreated. Matrix, a trowel applied cement-based repair mortar that is also resistant to deicing salts, was selected as the material for the deeper patchwork. The contractor color matched Matrix to the original limestone. Deteriorated sections were cut out, removed, and repaired with the customized Matrix. MIMIC TR, a brush applied cementitious repair mortar designed for thin repairs, was used where the removal of stone was not necessary. Both Matrix and MIMIC TR were ingeniously textured with a hair pick to replicate the sought-after bush hammer effect and blended the old with the new.

Project History

This building, originally built in 1927, was primarily constructed of brick and brownstone. All loose brownstone was removed and the remaining sections were treated with a consolidant. Matrix was used to recreate the detailed, ornamental floral pattern. In order to keep the color consistent between new and existing building materials, Matrix TR was used.
