- Application Overview
- Environment
Apply when air, surface, and material temperatures are between 55°F and 100°F (RedLine version between 35°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.
- TerraQuartz Aggregate
Broadcast the quartz in an upward motion to allow it to rain onto the surface evenly. Broadcast within 30 minutes for the TQ BaseCoat. Broadcasting to rejection will require approximately 50 pounds of quartz per 100 square feet.
- Second Broadcast
Remove excess quartz by sweeping and vacuuming. Apply a second coat of TQ BaseCoat and broadcast quartz to rejection.
- Sealer
Remove the excess quartz. Apply Sealer LS at 80-100 square feet/gallon. A finish coat of TerraThane® is applied to achieve the desired texture.
- 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.
- Mixing
Two Component Products
Premix Part A (resin) for 30 seconds with a drill and Jiffler or Hansen mixer. Slowly add Part B (catalyst) and continue mixing for 2 minutes. Mix at medium speed with the mixer immersed in the material to minimize air entrainment. Do not thin products.
- Double Broadcast
- First BaseCoat: Mix the TQ BaseCoat as described in 4.1. Immediately after mixing, pour the material onto the floor in a 6-12” wide stream. Spread with a drywall knife or squeegee at 100 square feet/gallon. Backroll with a 3/8” roller to spread evenly. Pour subsequent mixes to overlap rolled material. Always pour into a wet edge. Pouring into an edge that has set will create a noticeable surface defect. If an application break is necessary, break at a wall, doorway, or joint.
- TerraQuartz® Aggregate: TerraQuartz® Aggregate is broadcast into the wet basecoat. Broadcast the quartz in an upward motion to allow it to rain onto the surface evenly from above. Applying the quartz at an angle will cause ridges in the finish. Open time to accept quartz will vary depending on temperature and base coat used.. Always keep thebroadcast quartz at least five feet away from the wet edge of the basecoat. The seeding should leave no visible wet spots of the basecoat. An average rate of 50 lbs./100 square feet is required. Allow the surface to cure before continuing. Once the surface has cured, the excess quartz must be removed. Sweep or vacuum the surface. For a more uniform surface, the quartz can be scraped or to knock down high spots before vacuuming. The excess quartz can be saved for reuse.
- Second BaseCoat: Apply TQ BaseCoat at 85-100 square feet/gallon over first broadcast coat. Again broadcast TerraQuartz® Aggregate as was done in first basecoat application.
- Sealer: There are two products used to seal the dry quartz and finish the application: Sealer LS is a 100% solids light-stable epoxy based on hydrogenated epoxy technology,TerraThane is a light-stable aliphatic polyurea.
Depending on the surface profile and performance properties desired, the quartz may be sealed with one or two coats of sealer. For an aggressive profile, apply Sealer LS at 100-120 square feet/gallon. Spread with a non-marking squeegee. Backroll with a 3/8” nap roller until even. A finish coat of TerraThane® may be applied at 300 square feet/gallon. Pour the TerraThane® onto the floor and spread with a short, thin, flexible squeegee. Roll in both directions with a 3/8” nap roller to ensure complete coverage.
For a less aggressive texture, apply Sealer LS as the first seal coat at 80-100 square feet/gallon. Apply TerraThane® as the finish coat at a rate of 200-250 square feet/gallon.
- Clean Up
Two Component Products
Clean all equipment immediately after use with isopropanol (rubbing alcohol) or xylene. Read the SDS and follow all safety procedures for any cleaning material.
- Cure Time

Technical Details & Test Data
- Product Limitations
- Rising Temperatures
Concrete will outgas during periods of rising temperatures. To prevent bubbling, always apply when the application and cure temperatures will be constant or decreasing.
- Cracks
Moving cracks in the substrate are likely to transfer to the coating unless treated properly.
- Moisture
All concrete surfaces should be tested for moisture before applying a seamless coating. Water vapor transmission upwards through on-grade (or below grade) concrete slabs may result in system failure. If moisture emissions exceed 15 lbs./1000 sq. ft./24 hours, use of TerraPrime MM may not be recommended. Contact the manufacturer before application.
