Repairing terracotta includes matching the glaze with a highly permeable finish. Terracotta is found on many historic structures.
Where to use:
To create colored glaze finishes for brick and terracotta repair.How to apply:
Brush applied. Additional InformationPerformance Characteristics
- Used to create the base color or faux finish of repair area.
- Long-term protection.
- Two-coat application passes ASTM E514 for wind driven rain.
- Water vapor permeable.
- UV stable. Mildew resistant.
- Premium quality, exterior grade pigments minimize fading.
- 38 standard colors and custom matching.
Surface Preparation
- Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper adhesion.
- Prepare surface to be sandpaper-like texture (CSP 3) by mechanical abrasion or medium water blasting. Refer to ICRI Surface Preparation Guide 03732 for information about Concrete Surface Profile (CSP).
- Surface must be dry and frost free.
- Small voids, air pockets, static cracks up to 1/16 inch and irregularities should be filled with Matrix TR.
- Repair larger voids and damaged areas with Matrix or Matrix Superfine.
- Repair hairline to 3/4 inch cracks with Conproco Injection Grout (do not fill cavities). Available in 8 standard colors
Mixing
- Stir or mechanically mix using a low speed drill (400 – 600) until homogenous.
- Mix pails from different batches when an entire surface is visible.
Application
- Apply a test sample to determine adhesion. Test using ASTM D3359 cross-hatch adhesion procedure.
- Substrate temperature must be above 45°F.
- Ambient temperature must be above 45°F for the entire curing period.
- Brush apply a uniform 8 mils. wet thickness.
- Maintain a wet edge.
- Apply a second coat when the first is dry-to-touch.
- Apply Terracotta Finish (available in gloss or matte) over cured Terra-Color to achieve depth seen in most terracotta glazes or to recreate fire skin on brick.
Curing
- Protect from moisture for 24 hours.
Clean Up
- Clean tools and equipment with water. Clean adjacent areas with water before material dries.
Coverage/Yield
- 200 ft.²/gal. @ 8 mils. wet.
