APF CastorCrete SL – Urethane Cement Product Overview APF CastorCrete® SL is a high-performance, slurry-applied cementitious polyurethane flooring system designed for environments that demand extreme durability. Applied at 1/8 to 1/4 inch thickness using a gauge rake and trowel, this system resists physical abuse, impact, steel-wheeled traffic, and chemical exposure—including hot cooking oils, animal fats, and common solvents. This environmentally friendly system contains low VOCs and is made from sustainable raw materials. It may be applied to green concrete (7–10 days old) and to substrates showing 100% moisture (ASTM F2170). It also accommodates thermal movement and holds up under constant service temperatures up to 200°F (93°C). An optional anti-microbial additive is available to help inhibit bacterial and fungal growth. CastorCrete SL installs without a primer, making it a rapid-turnaround solution. It can be optionally top coated with CastorCrete TC, Polyaspartic 7500, Polyurea 5100, or Epoxy 600 or Epoxy 900 to increase chemical, UV, or abrasion resistance. Key Features Resists Thermal Cycling: Withstands steam, hot water, and fluctuating temperatures. Durable Surface: Handles steel-wheeled carts, impact, and abrasion. Green Concrete Friendly: Can be applied to fresh concrete (7–10 days old). Low Odor & Sanitary: Ideal for hygienic environments and food handling areas. Optional Topcoats: Compatible with multiple topcoat systems for added protection. Recommended Uses Food and beverage manufacturing plants Meat, poultry, and fish processing areas Commercial kitchens and prep areas Pharmaceutical production facilities Sanitary and wash-down environments Installation Notes CastorCrete SL is installed between 1/8 and 1/4 inch thickness using a gauge rake and trowel. It does not require a primer and can be applied directly to green or high-moisture concrete. It cures quickly, minimizing downtime. Topcoat selection depends on performance requirements—chemical resistance, UV stability, or visual consistency. Consult APF guidelines for detailed mixing, spread rate, and cure time instructions.
