Description
Ardex Premium Grade Aggregate is a pre-washed gravel with a 2-5 mm particle size, supplied for use alongside ARDEX levelling compounds. It is not a product used on its own: it is added to a mixed levelling compound to bulk it out for ramping and deep build-ups.
Levelling compounds are formulated for a limited depth range, typically up to around 20 mm laid neat. Adding a washed, graded aggregate lets the same compound be laid substantially deeper without slumping or excessive shrinkage, and reduces the material cost per square metre where a thick section is unavoidable.

Where to Use
- Building ramps from a levelling compound rather than a separate mortar
- Deep build-ups beyond a compound’s neat maximum thickness
- Filling substantial depressions or falls in a subfloor
- Reducing material cost per square metre on thick sections
How to Use
- Check the compound’s datasheet first — the mixing ratio and the depth at which aggregate becomes necessary are set by the levelling compound, not by the aggregate. ARDEX K 65, for example, is laid neat from 3 to 20 mm and takes aggregate above 20 mm, to a maximum of 50 mm.
- Mix the compound with its specified water to the consistency stated on its datasheet.
- Add the aggregate to the mixed compound at the stated ratio and mix through evenly.
- Place and finish following the compound’s normal instructions. Curing and traffic times are those of the compound.
Important Notes
- This aggregate is not a levelling compound and is not used on its own.
- Mixing ratios differ between compounds. Always work from the datasheet of the compound being used.
- Aggregate must be washed and dry before use — moisture affects the compound’s water ratio.
- Adding aggregate changes the surface texture. Where a smooth finish is required, apply a neat topping layer of the compound over the aggregated section.
