Secil Natural Hydraulic Lime (NHL)

Natural Hydraulic Lime, or NHL, is a versatile product that can be used in restoration mortar, heritage plaster and stucco, and in eco-building projects such as straw bale and hempcrete homes. We import NHL from Secil in Portugal and we're the primary supplier in North America. NHL is available in three strengths: 2 MPa, 3.5 MPa, and 5 MPa. This pozzolanic lime only requires the addition of sand - no cement is in the mixture - giving you a breathable and natural mortar or plaster. NHL 3.5 and 5 are sold in 25kg bags and NHL 2 is sold in 20kg bags.
