Limestone Emulsion

Tech-Dry® Limestone Emulsion is a neutral, water-based, water repellent limestone sealer, an impregnant and surface binder for permeable Australian limestone.

This limestone sealer is a non-caustic and user-friendly product, which is designed to penetrate deeply into the capillaries of limestone surfaces and render the substrate water repellent and strengthen the surface. It penetrates deeply into the capillaries of limestone surfaces to strengthen the substrate and make it water repellent.

As a high-quality limestone sealer from Tech-Dry®, it significantly reduces the absorption of water or other water-borne staining materials, which are major factors in deterioration of limestone buildings. Unlike other sealers, the treatment with this limestone sealer will not significantly change the appearance and the vapour permeability of the limestone substrate.


  • Water-based emulsion with no volatile hydrocarbon solvents.
  • Penetrates deeply into the limestone surface.
  • Bonds to the substrate with no peel or blister and provides surface dust binding.
  • UV, alkali stable and durable formulation.
  • No change to the surface appearance and vapour permeability.
