Liquid densifier for concrete surfaces
  • Improves abrasion resistance.
  • Single component.
  • Durable.
  • Cost effective.
  • Easy application.
  • Does not discolor the concrete.

Sethard S is a concentrated, clear, liquid surface hardener and dust proofer designed for application to concrete and other cementitious floors. Sethard S is based on an aqueous solution of sodium silicate and wetting agents to enhance surface penetration.
Sethard S is mixed with water and applied to concrete surfaces. Use of Sethard S will increase abrasion resistance and reduce dusting of concrete surfaces.


Sethard S is recommended for new and old cementitious surfaces, such as concrete floors and granolithic paving. It should not be used to renovate concrete which is already disintegrating. Typical applications include:

  • Factories.
  • Warehouses.
  • Garages.

Approximately 300 - 400 ft²/gal (7.3 - 9.8 m²/litre) per coat, depending on the texture and absorption characteristics of the surface.


Sethard S is available in 5 gal (18.9 litre) pails and 55 gal (208.2 litre) drums.
