Terracotta Finish

Repairing terracotta includes matching the sheen. Terracotta is found on many historic structures.

Where to use:

Replicate glaze on terracotta or fire skin on brick. Apply over Terra-Color to match surrounding undamaged terracotta.

How to apply:

Brush or roller applied. Additional Information

Performance Characteristics

Durable
  • Advanced chemistry provides long lasting protection from weathering.
UV stable
  • Will not yellow or discolor with age.
Anti-carbonation
  • Mitigates carbonation of concrete.
Breathability
  • Water vapor permeable.
Water repellent
  • Passes ASTM E514.
Environmentally friendly
  • Water based technology, low odor, non-flammable.
Two finishes
  • Gloss and Matte.

Surface Preparation

  • Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper adhesion.
  • If acid washing is used to prepare substrate, neutralize with 1 part ammonia to 3 parts water solution flooded over the surface. Residual acid in the substrate will cause Terracotta Finish to form a milky film instead of a clear finish. If this occurs, the material must be removed.
  • Surface must be dry at time of application to allow maximum penetration.
  • Protect adjacent areas from overspray.

Priming

  • Priming is not necessary under normal circumstances.

Mixing

  • Stir container.

Application

  • Always apply a test area to determine suitability of application.
  • Brush or roll material onto substrate in a uniform 6 mils. coat.
  • Brush out ponded material before surrounding area dries.
  • 2 coats are recommended for complete protection.
  • Allow the first coat to cure 3 – 4 hours @ 72°F; 7 – 8 hours @ 50 – 70°F before applying additional coats.
  • Each additional coat of Terracotta Gloss Finish will increase the intensity of gloss.

Curing

  • Protect from moisture for 24 hours @ 72°F.

Clean Up

  • Clean tools, equipment and adjacent areas with water before material dries.

Coverage/Yield

  • Actual coverage will vary depending on substrate porosity. Test application should be applied to determine actual coverage, number of applications required and compatibility with substrate.
Typical coverage
  • Terracotta – 200 – 300 ft.²/gal. MIMIC/Matrix – 150 – 250 ft.²/gal. Brick – 200 – 300 ft.²/gal. Concrete block – 75 – 125 ft.²/gal.

Product Handling

Packaging
  • 1 gallon container.
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

  • If acid washing is used to clean, substrate must be neutralized with 1 : 3 ammonia/water solution flooded over the surface.
  • Do not apply if precipitation is forecast within 24 hours of application.
  • Do not apply in strong winds.
  • Do not apply to frozen surfaces.
  • Do not apply if temperature of substrate is below 45°F.
  • Do not apply if ambient temperature is below 45°F.
  • Do not apply in areas susceptible to water ponding.

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 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.

Disposal

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

Architectural Terracotta glazes vary from a flat finish to a high gloss.  Repairing flat finishes can be done in one step (TerraColor).   Matte and High Gloss finishes require the application of Terracotta Finish.  These clear coats not only replicate the sheen but also provide additional protection.  Multiple coats of either Matte or Gloss can be applied to get just the look you need.

Burton School

Project History

The Burton School was opened in 1926. Henry H. Turner, the preferred architect for the Grand Rapids School District in the 1920s and 1930s, designed it; and it was the first public school costing one million dollars to build. Matrix was chosen because color matching can be done on-site by trained applicators, eliminating sample lead times, cutting job start-up time, and any over-ordering of material. Primex, M3P and Terracotta Finish were used with the knowledge that they are fully compatible and work beautifully with the Matrix repair system. Because this was a LEED project, M3P was a great paint solution because it is a water-based, low VOC coating.

The Cathy Green Building

Project History

The Cathy Green Building is located at 111 North Main Street in the small town of Plainwell, Michigan. Once home to the town bank, it is now filled with local shops, including building owner Cathy Green’s Bridge Street Gallery. During restorations in the 1970s a wooden roof structure was added to the building. In 2009, the decision was made to remove the wooden structure and restore the building to its original state. Many components of the building were completely destroyed during the erection of the wooden structure. To accomplish the restoration, cast stone pieces were made to replace pieces that had been destroyed. While erecting the wooden structure, the original terracotta walls were drilled through for anchoring purposes. All of those walls were “broken” and were rebuilt using Matrix.
Matrix is a repair mortar made specifically to match the appearance and physical characteristics of terracotta. M3P was applied to the newly rebuilt areas to match the rest of the building’s original terracotta
.
