Ecologic Mortar
Ecologic™ Mortar, in any of the stock colors, are simply a prepared blend of binder/aggregate/pigments to which you just add water, mix and go to work. Use it to repoint historic buildings, stucco and build new buildings. This is considered an ultimate green application and results in a desired "old world" lime finish. It is as simple as mixing the mortar with water using a high torque industrial electric drill and a rigid paddle attachment in five-gallon pail or using a mason's paddle-style mortar mixer. The bag weight is 38.5 pounds.
Ecologic™ Mortar is coded as "DGM" followed by "SCG", which means "Standard Construction Grade" where no pigment is added.
Type "G" sand stands for "coarse granules" for most applications. We find it to be the most popular option. The granules in Type G are coarse in comparison to the fine sands in a Type F mortar, but the coarse granules are likened to regular mason's sand that meets ASTM C-144 standards for sharp, well-graded sand. The coarse grains are not as coarse as typical concrete sand.
No portland cement is present in Ecologic™ mortars. Ecologic™ mortars will still reach over 750 p.s.i. as is required for a type N mortar while maintaining a high permeability that is beneficial for repointing and repair work on historic structures originally built with lime and sand mortar.
Ecologic™ Mortars can be used for sustainable applications in stucco, interior plaster, laying up of masonry units, stonework and as historic building repointing mortars.
Ecologic DGM SCG-G (the untinted NHL 3.5 with coarse grain sand) is the default and stocked item. Other color and grain options are available by special order. Please contact us for more details.
Many factors affect how these images may appear on your computer monitor and how it prints on your specific printer. It is suggested that you purchase the Ecologic™ Mortar sample kit so that you may view each strip individually or hold one or more of these channels of dried mortar up to a building to determine a match when planning to duplicate a repointing mortar.
About NHL
Natural Hydraulic Lime, although it is basically of the same chemical composition as Hydrated Lime, has its initial set with water, much like cement, and a second set by absorption of CO2. Being "hydraulic" allows for simplicity in many applications. Hydraulic Lime, like Hydrated Lime and cement requires some basic care such as minimizing the amount of mixing water, using good sand and tarping the work. The cost of labor when using NHL is therefore comparable to normal cementicious mortar and stucco installations which have been carried out correctly.
The hydraulicity, (which in true form is the ability to set with water and under water), for the St. Astier lime range is achieved only by the nature of the raw material. The St. Astier raw material is a naturally occurring hydraulic lime which is low-temperature fired. Nothing else is added to St. Astier NHL, therefore it is known as "Natural" Hydraulic Lime. It has known and measurable performance criteria which is both comforting and predictably dependable.
