Earth Binder

Tech-Dry® Earth Binder is an acrylic sealer used to dust-seal and strengthen the internal or external surfaces of earth structures. Use an acrylic sealer to penetrate the capillaries of earth substrate surfaces, thus providing the substrate with a dust-sealing effect and surface abrasion resistance.

Earth Binder is recommended for dust-sealing especially the internal surfaces of rammed earth buildings. This acrylic sealer can also be used for external surfaces of earth structures or other porous masonry substrates. It can also be used as a primer before rendering for earth buildings or other porous substrates, to strengthen the surface and to improve the adhesion of the render.

Some of the important features of Earth Binder include:

  • Water-based non-toxic formulation.
  • Penetrates into the masonry substrate surface with no peeling or blistering.
  • Provides dust-sealing and surface abrasion resistant effects.
  • Does not significantly change the surface appearance and vapour permeability.
  • Improves strength and adhesion of the earth
