🏗️ Concrete Hardener Comparison – Why Nano Silica Wins

Choosing the right concrete hardener is critical for achieving durable, high‑gloss polished concrete floors. At Polerad Betong AB, we manufacture nano silica‑based densifiers and shields that outperform traditional sodium, potassium, and lithium hardeners. This page highlights the key differences so contractors and facility managers can make an informed choice.

💎 Nano Silica vs Traditional Hardeners

Nano Silica Densifiers

• Highest Strength & Abrasion Resistance – Creates a denser, harder surface that withstands heavy traffic.

• Superior Gloss & DOI – Achieves the highest gloss and distinctness of image (DOI) readings when polishing concrete floors.

• Enhanced Penetration – Nano silica molecules penetrate deeper, forming a tighter microstructure.

• Ready to Polish in 1 Hour – Save valuable time on site with fast reaction.

• Cost‑Effective Concentrate – Supplied as concentrate, diluted with ordinary drinking water. This reduces freight weight, storage space, and overall €/m² cost. Factory‑direct supply means you often get the best price for premium quality.

• Eco‑Friendly – Lower VOCs and reduced environmental footprint.

Sodium, Potassium & Lithium Hardeners

• Lower Strength – Less abrasion resistance, shorter lifespan under heavy use.

• Limited Gloss & DOI – Cannot match the shine and clarity of nano silica.

• Shallow Penetration – Less dense microstructure, reduced durability.

• Higher Costs – Delivered ready‑mixed, heavier to ship, less efficient per m².
