- Application Overview
- Environment
Apply when air, surface, and material temperatures are between 60°F and 90°F. The surface temperature must be at least 5° above the dew point to prevent moisture condensation.
- Substrate
The concrete must be structurally sound and free of oil, grease, and other contaminants. When applying directly to concrete, the concrete must first be prepared by shot blasting, scarifying or acid etching to create a surface profile equivalent to 40-60 grit sandpaper.
- Mixing
Part “A” should be mechanically pre-mixed for 60 seconds before adding Part “B”. After adding Parts “A” and “B” together, mix for 90 seconds. Do not hand mix.
- Application
Immediately pour activated product on the substrate and, using a squeegee, pull out the material at the desired coverage rate. Rolling Using a 3/8” nap non-shedding roller, roll the product in both directions to ensure even coverage.
- Recoating
If additional coats are desired, they must be applied within 24 hours, or the cured Sealer LS must be sanded before application.
- Recommended Uses
- Finish coat over TerraRich® or PT Clad heavy-duty topping
50 mil anti-skid system for:
- splash and spill chemical exposure
- light to medium service areas
Thin film system
- light service areas
- Clear sealer for TerraQuartz® and TerraChip® systems
- Maintenance
Do not wash the floor within 5 days of installation. Exposure to water before the floor is completely cured may dull the finish. Damp mop as needed with a clean mop head and clean, warm water with a mild detergent or degreaser. Rinse thoroughly to avoid leaving residue. When using a new cleaner for the first time, test clean an inconspicuous area to ensure compatibility with the floor.
- Application Conditions
Concrete Condition
- General
Concrete must be structurally sound and free of oil, grease, and other contaminants. New concrete must be thoroughly cured to prevent shrinkage cracks. Typically, 14 days at 70°F is sufficient.
- Cracks, Sawcuts, Expansion Joints
Cracks, sawcuts, and expansion joints must be identified and characterized prior to installation. Cracks must be evaluated to determine if they are stable or moving. The method of crack treatment is dependent on the type of crack. Sawcuts and expansion joints should not be covered when the surface will experience changing temperatures.
- Moisture
Excess moisture emissions can cause coating delamination. All concrete surfaces should be tested for moisture prior to applying a seamless coating. There are several methods available. ASTM D-4263 is a qualitative test using a plastic sheet. The calcium chloride test provides quantitative results. If moisture emissions exceed 3 lbs./1000 sq. ft./ 24 hrs, or concrete relative humidity exceeds 75% per ASTM F2170, TerraPrime MM may need to be installed prior to application of TerraQuartz® system. Contact applicator for details.
Environmental Conditions
- General
Store materials in clean, dry conditions at temperatures between 65°F and 90°F. . Consult TDS for application temperature guidlelines, making sure the approriate version of BaseCoat and TerraThane are used for the existing conditions. The temperature must remain within this specified range for a minimum of 24 hours after application. The surface temperature also be at least 5° above the dew point.
- Rising Temperatures
Concrete will release air during periods of rising temperatures. This can result in bubbles in the coating even in apparently well sealed concrete. To prevent bubbling, always apply coatings when the application and cure temperatures will be constant or decreasing.
- Surface Preparation
Cleaning
Oil, grease, and other contaminants will inhibit bonding. Remove by first scraping any thick, caked deposits, then by scrubbing with an appropriate cleaner. Always finish with a warm water rinse. Test the treated area with a 1:2 mix of muriatic acid and water. (Always add acid to water.) A white haze of bubbles indicates a clean concrete surface.
Surface Profile
Surface laitance and loose concrete must be removed. The substrate must be prepared to a surface profile of CSP 2 or 3 by diamond grinding or light shot blasting. Acid etching can be used on new concrete, but mechanical preparation is always preferred and is the only acceptable method for old concrete and for new concrete if curing agents, hardeners, or sealers are present.
Surface Repairs
- Voids, Popouts: Remove all loose concrete from the damaged area. Fill as necessary with TerraRich or Patch Filler.
- Stable Cracks: Minor shrinkage cracks can be bridged without special treatment. For wider cracks, route the crack in a “V” cut to a width of ½” and a depth of at least ¼”. Clean the area and fill with an epoxy grout.
- Moving Cracks: Cracks less than 1 /8” : Apply 8-10 mils of TerraFlex 16-24 inches wide centered on the crack. For larger cracks, saw cut the crack to a width of ½” and a depth of at least 1”. Clean the area and insert closed cell backer rod leaving an opening ½” deep. Fill the crack with TerraFlex and apply 8-10 mils of TerraFlex 16-24 inches wide centered on the crack.
- Expansion Joints: Remove all material from the joint and insert closed cell backer rod. Leave the backer rod protruding from the joint during application to prevent the joint from being filled. Install the flooring up to the backer rod. After installation, depress the backer rod to a depth of ½”. Lightly sand the edges of the flooring system adjacent to the joint. Depress the backer rod, clean the joint, and install an appropriate sealant.
- Drains: If a drain is surrounded by a joint, treat as outlined above. Seal all drain openings prior to application.
- Anti-Skid system
Broadcast Anti-Skid system
- BaseCoat
TerraPrime or TerraSeal may be used as the basecoat for the aggregate. Mix the coating as described in 4.1. Immediately pour the material onto the floor and spread with a squeegee or drywall blade. Spread the coating according to the desired thickness. Standard thickness is 100 square feet/gallon for a 55 mil system. Backroll with good quality 3/8” nap nonshedding roller.
- Aggregate
Broadcast aggregate into the wet slurry. Broadcast in an upward motion to allow the aggregate to rain onto the surface evenly from above. Applying the aggregate at an angle will cause ridges in the finish. Aggregate may be broadcast by hand or with a spray pot. Always keep the broadcast aggregate at least five feet away from the wet edge of the applied slurry. The seeding should leave no visible wet spots in the slurry. Use about 50 pounds of aggregate per 100 square feet into a 16 mil basecoat. Allow the surface to cure before continuing. Once the surface has cured, the excess aggregate must be removed. Sweep or vacuum the surface.
- Sealer
TerraSeal is used as the finish coat. Mix the coating as described in 4.1. Immediately pour the material onto the floor and spread with a squeegee or drywall blade. The texture of the system can be varied by adjusting the spread rate of the coating. Spreading the coating at 100 square feet/gallon will leave an aggressive texture; spreading the coating at 65 square feet/gallon will leave a moderate texture. Backroll with good quality 3/8” nap non-shedding roller.
