Traffic-Rated Concrete Overlay
Fiber-Reinforced Heavy-Duty Concrete Surface Repair
Durável TRO is a heavy-duty traffic-rated concrete overlay system engineered to restore broom-finished texture to worn concrete and repair spalls and salt damage. The nearly invisible fiber reinforcement in the mix significantly increases flexural strength and tensile strength. Duravel TRO can resurface driveways, sidewalks, commercial entryways, loading docks, and most other concrete surfaces requiring a heavy traffic coating.
Durával TRO™ – Don’t Just Overlay it… Durável It!
The just-add-water mix is self-bonding and cures to over 6,000 PSI. Durával TRO will handle all residential and commercial traffic, including forklifts. Durável TRO is installed on parking lots, parking decks, driveways, sidewalks, commercial entrances, and other exterior and interior horizontal surfaces. The overlay is installed with conventional concrete tools. Finish options include smooth trowel, broom texture, and a range of decorative textures. The single-component bag mixes are available in three formulations: Light Grey, Dark Gray, and White. Durável TRO White may be field tinted to over twenty decorative colors.
MIXING INSTRUCTIONS
Mix single bags in clean 5-gallon pails with a helical mixing blade or use a mortar mixer for multiple loads. Water demand varies with environmental conditions and application, between 5 and 6.5 quarts per bag (4.7 to 6.2 L). For best results and longest pot life, use clean, cold water – run hot water out of hoses prior to using for mixing – and keep bags cool by not storing in direct sun. Measure mix water into the mixing vessel. If applicable, add pigment to the water and thoroughly blend. While mixing, slowly add the bag contents, then mix to a lump-free consistency, being sure to scrape any unmixed product from the sides and bottom of the mixing vessel. Mixed products should be applied promptly. If the product stiffens in the bucket, dispose of the mix, do not add more water.
APPLICATION INSTRUCTIONS
As a Repair Mortar:
Pre-wet substrate to Saturated Surface Damp (SSD), and continue wetting as needed during product application. Pour out mixed product onto the repair area, then spread with trowels and/or squeegees. Durável TRO may be applied at a thickness of up to 1/4″; use the product in lifts for thicker repairs.
When Troweling:
Pre-wet substrate to Saturated Surface Damp (SSD), and continue wetting as needed during product application. Pour out mixed product onto the substrate in ribbons over the immediate work area, then spread evenly with trowels and/or squeegees. Under normal conditions, the mixed product has a +/- thirty-minute pot life, so it is optional to pour out the entire mix at once. The typical coverage rate is 180 square feet per bag per application. Finish the first coat (base coat) smooth. The topcoat may be troweled smooth by hand or power trowel or finished in a broom texture using a concrete (broom) brush.
When spraying:
Keep the substrate dry. Use a hopper gun or compressed air sprayer to apply mixed product to the desired texture. Coverage ranges from 120 to 150 square feet per bag, depending on the texture applied.
NOTE: Do not apply Durável TRO in locations that are permanently submerged.
Durável TRO is a heavy-duty traffic-rated broom concrete overlay system that is engineered to restore texture to worn concrete, and to repair spalls and salt damage.
