Installing Urethane Slurry Mortar System

Urethane cement flooring, specifically Kraftig SL, is a premier choice for environments that demand high durability and resistance to harsh conditions. Common applications include commercial kitchens, food preparation areas, and industrial facilities. These coatings are engineered to withstand significant thermal shocks, abrasion, and moisture, making them some of the toughest options available in the market.

Preparing the Surface

The installation process begins with proper surface preparation. To achieve the ideal concrete surface profile (CSP) of 4 to 5, the concrete must be ground using a 30-grit diamond pad or shot-blasted. This preparation ensures the urethane cement adheres well and provides a robust foundation for the subsequent layers.

Application of Urethane Cement

The application of Kraftig SL involves a few critical steps:

  • Mixing: Combine the four-part resin which includes hardener, aggregate, cement blend, and optional pigment packs.
  • Application: Pour the mixed urethane mortar slurry onto the prepared surface.
  • Spreading: Use a gauge rake to evenly distribute the slurry at a thickness of about 1/8-inch.
  • Smoothing: Finish the surface with a smoothing paddle to eliminate any uneven spots.

Decorative and Protective Finishing

After the base layer, a decorative quartz broadcast can be applied. In the demonstration, the “Oceana” colored pigment was used:

  • Broadcasting: Spread the colored quartz aggregate evenly across the wet slurry, ensuring full coverage without clumping.
  • Curing and Cleaning: Allow the slurry to set before vacuuming off excess quartz.
  • Sealing: The final step involves applying Duraamen’s Perdure P72 polyaspartic sealer. This topcoat is scratch-resistant, UV-stable, and enhances the floor’s appearance and durability.
