ARDEX Coarse Aggregate 3mm is a dry, pre-packed material designed to bulk out smoothing compounds and thicken epoxy primers. Commonly used in construction projects, it is a versatile aggregate that enhances concrete strength and improves overall stability.

 

 

ARDEX Coarse Aggregate 3mm is a dry, pre-packed, graded aggregate specifically designed to “bulk up” ARDEX subfloor smoothing compounds for thicker applications. It is mixed directly into the smoothing compound as per the manufacturer’s instructions, making it ideal for leveling large uneven areas or creating a strong base for heavy floor coverings.

Preparation

  • Ensure the subfloor is clean, dry, and free of contaminants such as dust, grease, or old adhesives.
  • Follow ARDEX guidelines for substrate preparation to ensure optimal adhesion and performance.

Application

  • Mix ARDEX Coarse Aggregate with a suitable ARDEX smoothing compound, adhering to the recommended mixing ratios outlined in the product data sheet.
  • Use the mixture for applications requiring thicker layers, such as leveling uneven subfloors or creating a stable base for heavy floor coverings.

Usage Guidelines

  • Thicker Applications: Specifically designed to allow for thicker layers of smoothing compound.
  • Not for Stand-Alone Use: ARDEX Coarse Aggregate must always be combined with an appropriate smoothing compound and should not be used on its own.

Mixing Tips

  • Use clean tools and equipment for mixing to prevent contamination.
  • Ensure the mixture is well-combined for consistent application and strength.

By following these steps, ARDEX Coarse Aggregate 3mm can enhance the performance of ARDEX smoothing compounds, providing a durable and reliable solution for thicker subfloor applications.
