Description

Use Roundtower  Natural Hydraulic Lime (NHL) 2.0, is for interior/exterior plastering, stucco, and soft brick/stone re-pointing.

Recommended Uses:

  • Older soft bricks
  • Sandstone
  • Projects requiring softer mortar
  • Interior and Exterior Plasters/Stuccoes

Characteristics:

  • Permeable
  • Regenerative (self healing)
  • Free Lime adds elasticity

The higher permeability of  NHL 2.0 is designed for humid settings, or areas with extreme or fluctuating conditions, to expand and contract with the weather. This allows moisture to escape through the mortar joints or plaster allowing the building to “breathe”. “Breathing” through the mortar joints, plaster, and stucco help to prevent interior molds, mildews, and decaying interior wood.  Modern types of mortar can’t adapt as readily as NHL 2.0 and will trap water, crack and become brittle over time.

Natural Hydraulic Lime (NHL) 2.0 has up to 10% of active hydraulic components, like clay, and will set within one week of mixing with water.

Use NHL 2.0 with Coarse Hemp Shiv to create a plaster basecoat with insulation.

Imported from Ireland, a county with some of the world’s oldest buildings, they’ve created a mortar that will not harm historic structures.

This product comes dry and you will need to purchase your own Mason’s sand. Remember, the color of the sand will largely determine the color of the mortar. Pigments can be added.
