Ecologic Lime Mortar from Limeworks is a prepared blend of binder, aggregate, and pigments to which you just add water, mix, and go to work. The dry ingredients have already been prepared so that you get the right type of hydrated lime, the correct blend of screened sand, and earth pigment if needed.
Does not contain any Portland cement.
A traditional lime finish that can be used indoors or outdoors, use the Coarse blend (Type G) for joints over ⅜ of an inch, such as in making a mortar to repoint brick and stone, or as a base coat for finer plaster to be applied on top. Use the Fine blend (Type F) for joints between ¼ and ⅜ of an inch, and butter joint to be used for joints under ¼ of an inch.
Ecologic Mortar comes as a bagged dry mix. Add water and mix with water using a high torque industrial electric drill and a drill mixer attachment in five-gallon pail or using a mason's paddle-style mortar mixer.
Mixes differ according to application
Type G stands for "coarse granules" for most all other applications. 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.
Type F stands for "fine sands" for the application of butter joint repointing, fine jointed Ashlar stonework and for a smooth plaster finish. Base coat with the coarser "G" mix.
All stock Ecologic Mortars are made with NHL 3.5 and sand blend.
Ecologic Lime Mortar will reach the 750 psi required for a Type N mortar while maintaining the high permeability required for repointing and repair to historic structures, originally built with lime mortars. Due to the lack of Portland cement, Ecologic Lime Mortar is immune to sulfates and salts.
Use these averages as a guide to determine how many bags of Ecologic Lime Mortar you will need for your project. One bag of Ecologic Lime Mortar is good for:
Repointing about 40 SQFT of standard brick joints @ ⅜ in wide and ¾ in deep.
Repointing about 80 SQFT of butter joint at less than ¼ in wide and ¾ in deep.
Repointing about 15 SQFT of rubble stone wall @ 1 in wide and 1-¼ in deep.
