Matrix TR

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.
