No.1 Fine Sand – Washed Fine-Grain Sand for High-Density Screeds
No.1 Fine Sand is a premium, washed fine-grain sand designed for use in dense and compact screed applications. With a particle size typically ranging from 0.1mm to 0.6mm, it creates a smoother, tighter matrix when mixed with cementitious binders, reducing air voids and increasing surface strength.
This sand is ideal for use with Technokolla Kronos screed binder where a finer aggregate is desired—for example, in low-profile screeds, over underfloor heating systems, or where higher compressive strength and a more refined finish are required.
Key Properties:
-
Washed & Fine-Graded: Ensures purity and consistency for dense screed compositions
-
Enhanced Compaction: Finer particles fill voids more efficiently, resulting in a smoother finish and improved strength
-
Low Porosity Mixes: Ideal for applications needing minimal water absorption or high wear resistance
-
Superior Surface Quality: Produces a flatter, more refined screed ready for direct installation of coverings
Main Uses:
-
High-Density Screeds: Especially effective with Technokolla Kronos for fine finishing screeds
-
Thin-Section or Low-Build-Up Screeds: Where height or weight is limited
-
Over Underfloor Heating: Ensures even heat transfer and reduced air entrapment
-
Preparation for Vinyl, Carpet, or Tiling: Offers a smoother surface profile for delicate or thin coverings
No.1 Fine Sand provides the precision and density required for specialty screeding work, particularly when partnered with the Kronos system. It’s the preferred choice for installers seeking greater control, smoother finishes, and high-performance underlayments.
