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. [expand title=”Additional Information” swaptitle=”Minimize 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.
