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.  

APF Epoxy 300 FLEX PASTE – Flexible 100% Solids Joint and Crack Filler Product Overview APF Epoxy 300 FLEX PASTE is a 100% solids, medium-viscosity flexible epoxy system designed for high-performance industrial joint and crack repair. With excellent elongation, impact resistance, and bonding strength, this thixotropic paste provides long-term performance in environments exposed to vibration, surface movement, or heavy loads—including steel-wheeled traffic. It bonds tenaciously to both concrete and properly prepared metal substrates. Developed for use as part of the APF Epoxy 300 FLEX floor system, FLEX PASTE performs exceptionally well on suspended slabs, mechanical rooms, wood decks, and exterior flooring systems. It can also be used to coat properly prepared aluminum and steel, including marine deck applications. A Fast Cure version is available for cold weather or accelerated project schedules. Key Features Flexible, Thixotropic Paste: Ideal for non-dynamic joints and structural cracks. Impact & Load Absorption: Designed for steel-wheeled traffic and vibration-prone areas. Cold Weather Cure: Fast Cure option available for application down to 40°F. Waterproofing Capable: Functions as a membrane in damp or exposed environments. Steel & Marine Applications: Bonds to properly prepared aluminum and steel ship decks. Recommended Uses Manufacturing and warehouse floors Mechanical rooms and suspended slabs Veterinary and healthcare facilities Retail and institutional flooring Correctional and pharmaceutical facilities Wood decks and exterior aggregate-filled systems Steel ship decks and marine structures Installation Notes APF Epoxy 300 FLEX PASTE should be applied to clean, dry, and properly prepared substrates. Trowel or knife grade application is recommended for filling joints and cracks. When used on metal, surface prep is critical for bonding performance. For cold weather or faster cure times, select the Fast Cure version. Always consult APF’s technical data sheet for coverage rates and cure time details.

APF Oil Stop Primer – Epoxy Primer for Oil-Contaminated Concrete Floors APF Oil Stop Primer is a professional-grade 100% solids epoxy primer formulated to bond to oil-soaked or hydrocarbon-contaminated concrete. Whether you’re dealing with motor oil, hydraulic leaks, solvents, or transmission fluid, this low-viscosity formula penetrates deep into the slab and delivers a reliable bond where other primers fail. For garages, machine shops, or industrial floors with embedded oils, APF Oil Stop Primer helps prevent delamination and promotes long-term adhesion of your epoxy system. Key Benefits Bonds to Oil-Contaminated Concrete – Engineered for surfaces affected by oils, fuels, and solvents. Excellent Surface Tolerance – Works even when surface prep isn’t perfect. Strong Adhesion – Reliable base layer for flake, solid color, or industrial epoxy systems. Efficient Coverage – Covers approximately 125 sq ft per kit using a 3A:2B mix ratio. Recommended Applications Auto repair shops and service bays Garage floors and residential workshops Machine shops with oil or fluid residue Warehouses with forklift or vehicle leaks Note: Not intended for food-grade environments, chemical processing plants, or areas routinely cleaned with hot water or aggressive detergents. Contact APF Technical Support for those applications. Product Specs Color: Clear (not tintable) Mix Ratio: 3A:2B by volume Kit Size: 1.25 gallons Coverage: ~125 sq ft Type: 100% solids epoxy primer VOC: Low Start with the Right Primer APF Oil Stop Primer gives you confidence when applying epoxy over oil-stained or solvent-penetrated concrete. Avoid costly failures by using the right product on the first coat. A clean bond means no peeling, bubbling, or lifting—just a professional finish that lasts.
