ARDEX PC-T 4 is a rapid-drying, cement-based compound designed for creating polished concrete floors that are walkable in 2-3 hours and ready for polishing in just 24 hours. Suitable for internal use only, ARDEX PC-T 4 is ideal for fast-track installations in environments like retail stores, schools, and airports. It can be applied from 10mm to 50mm in thickness and up to 130mm with the addition of graded aggregate, although a minimum thickness of 15mm is recommended for optimal leveling. For thicknesses over 30mm, adding larger aggregate may be beneficial; consult ARDEX Technical Se
