Graymont Hydrated Limes
We have been a stocking distributor and representative for Graymont for over 25 years. In our Toronto warehouse we stock Ivory Finish Lime Type S, Mortaseal Mason's Lime Type S, and Bondcrete Mason's Lime Type SA from Graymont's Ohio plant. These dolomitic hydrated limes are used in plastering (Ivory) and masonry applications (Mortaseal and Bondcrete) and are sought after for their plasticity and bright white colour.
Graymont Niagara Slaked Lime Putty
Niagara mature lime putty is a high-purity dolomitic lime putty product that is fully slaked and screened for immediate use. This product is aged for a minimum of two months and has exceptional plasticity that is beneficial in dry mortars such as those used for tuck pointing. We stock Niagara lime putty in 3 gallon pails and 45 gallon drums.
Graymont High Calcium Quicklime
We carry high calcium quicklime in a 1/8" - 3/4" pebble format. This product is used in "hot mixes" to create historic style lime mortars. This product is available in 5 gallon pails or 3000 lb. sacks.
Graymont Pozzolanic Hydrated Lime (PHL)
Graymont manufactures two blended hydraulic lime products, NIAGARA PHL 3.5 and 5.0. These products have been designed for use in restoration applications and meet the requirements of ASTM C1707. They can be used in repointing, plastering, and grouting applications on historic or contemporary projects. These products are perfect for restoration applications where ordinary Portland cements or masonry cements are not compatible with the existing masonry system. PHL 3.5 and 5.0 are available in 50-lb. (22.5-kg) bags.
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.
