Self-Leveling Polishable Concrete Topping With Aggregate

SpecLevel PCT-AGG is a premium, cement-based, self-leveling, and polishable concrete topping, uniquely pre-extended with special aggregates to achieve a natural architectural concrete finish. Engineered for ease of use and versatility, it delivers a dense, hard surface that can be diamond polished in just 24 hours, drying to a light concrete gray that beautifully accepts integral colors or stains.

  • When mixed according to instructions, provides a self-leveling wear topping with a 20-minute flow time at 70°F.
  • No troweling required; self-leveling and pumpable for ease of application.
  • Ideal for achieving a smooth, durable surface ready for polishing.
  • Compatible with integral colors and concrete stains for aesthetic versatility.
  • Suitable for application in thicknesses from 3/8” to 1.5”, extendable up to 5” with additional pea gravel for deeper applications.
  • Designed for both heavy load areas and achieving optimal aggregate exposure.

Application

Surface Preparation

  • Ensure cleanliness:Remove all contaminants, including oils, curing compounds, and loose materials.
  • Surface profiling:Concrete substrates should be profiled to a minimum CSP #4, with shot blasting preferred.

Mixing and Application

  • Mixing:Use 7.0-7.5 pints of water per 50-pound bag for standard consistency.Adjust water for desired flow characteristics.
  • Application:Pour or pump the mixture over the prepared substrate.Spread using a long-handled spreader or gauge rake.The material self-levels; no troweling is necessary.

Placement Procedure

  • Pumping:Can be pumped using an appropriate grout pump; ensure material levels itself during the first 20 minutes at 70°F.

Finishing/Curing

  • Foot traffic:Accepts foot traffic within 2-4 hours, depending on conditions.
  • Polishing:Can be diamond polished within 24 hours of application.

Shelf Life

Unopened bags have a shelf life of 12 months when stored in suitable conditions, away from excessive humidity and temperature fluctuations.
