Ecologic® Mix N' Go 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 which are considered a Green Application and result 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 a number to correspond to a certain stock mortar color. "SCG" on bags means "Standard Construction Grade" where no pigment is added. Type "F" stands for "fine sands" for the application of butter joint repointing, fine jointed Ashlar stonework and for smooth stuccos. 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 and Type G sands have a range of grades making up the majority of the component sizes in the entire sand blend. All Stock Ecologic™ Mortars are made with NHL 3.5 and “G” type sand blend. Ecologic™ Mortar (F) with fine sand is also made with NHL 3.5 and is a stock product in the SCG Non-Pigmented color only. All other mixes are considered a custom blend.

Ecologic® Lime Mortar Colors

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® Lime Mortar Kit and Color-Matching System

An Ecologic™ Mortar kit has the 12 stock colors of Ecologic™ Mortar and 4 custom blends using our stock colors. The four example blends have some commonly found inclusions added to more closely match some typical historic mortar joints. This is done as an example of how you could use the 12 stock colors to produce hundreds of new shades and find ones specific to your various applications. The 4 custom blends have the inclusions and aggregates slightly exposed to duplicate a weathered surface in order to demonstrate how you can tweak the final appearance of a mortar to make it an indistinguishable match such as for patch pointing applications on historic buildings. You can hold one or more of these strips up to the original mortar on a building to ascertain which stock color or blend may be a match. Ecologic™ Mortar colors are earth tone shades developed over 25 years to duplicate the majority of the mortar colors found on vintage buildings throughout the United States. You can add local aggregates from your region in various degrees in order to more closely match the color and texture of the building’s original mortar joints when the joints are properly tooled.

Please call for advice or if you need service regarding where to mail samples for mortar analysis in order to have a custom mortar duplicated or to design a mix if one of our stock colors or blends will not suffice.

The cost of the mortar kit includes shipping to the address you specify.

Ecologic® Sand Mastic

Sand Mastic™ is a specially formulated dry powdered blend of Hydraulic lime and well-graded sands. Sand Mastic™ is mixed on-site with independently purchased raw and boiled linseed oils not included with the product. The mastic produces a flexible vertical and horizontal pointing mortar which can be used between the juncture of masonry and wood elements or where movement joints may occur.

Sand Library

For more extensive museum quality repairs please consider ordering a Building Conservator’s “Available Aggregate/Sand Library.” These are the aggregates available for custom Ecologic™ Mortar mixes intended to be used by the design of architectural conservators to more closely simulate original sands and inclusions found in historic mortar formulations.

Finish Tools- 1/2" slicker, Wire Duster and 1/2" ribbon jointer and a loop.

Panel #5

Limonitic sandstone (yellowish brown) pointed in a Grapevine Stone joint, (not to be confused with the commonly named grapevine joint in brickwork where in that case an incised 1/8 line is impressed into the wet mortar when striking with a grapevine jointer tool.)

Appalachian Bluestone (a sedimentary sandstone) pointed in a **Beveled Ridge joint which had the yellow sand aggregates exposed for a weathered appearance

Mortar Mix: 1 part Ecologic™ Mortar G #DGM 100 (light brown/mud colored) 2lbs yellow concrete sand (Inclusions of lime chunks were also added along with the sand aggregate to duplicate the imperfection often seen in weathered mortar where the original lime slaking left bits of calcium hydroxide not fully broken down in the putty and where weathering reveals such bits. This denotes a "hot mix was used and fresh slack lime had sand added then used immediately). Mix NHL 5 and water, let it harden a week and break it up to add small bits.

Panel #7

Exterior, weathered, (by exposing aggregates) brown coat plaster (AKA stucco, render). Inclusions of lime chunks (see note above) were dashed into the wet plaster

Finish Tools - 1/2" slicker, Churn brush

Note to those in Mt. Airy Region of Philadelphia- The above mix, or substituting DGM 200, is a good match for most Wissahickon Schist repointing work needed on buildings built before 1940.

Panel #10


The Overhung Ridge joint is often misinterpreted as one of the ribbon joints mentioned above. Overhung Ridge is a joint that meets the flush face of the semi-squared block of stone above it, having a trailing edge to the stone above it and a ruled edge with a inward bevel meeting to the stone below it. Usually the left side of the head joint has the trailing edge and the right side of the head joint, the ruled edge with bevel.

Ecologic™ Mortar G #DGM 250 (greenish ochre-brown colored)

Tools - 1/2" ribbon jointer, loop and a level


Overhung Ridge Joint

Note that often in Overhung Ridge pointing of snecked rubble stonework, the head joints can be perfectly perpendicular with the horizontally level bed joints or the head joints are angled from the level bedding plane. From a distance this joint appears to make the semi-squared stones seem more squarely shaped. It also makes the joints look a lot like a ribbon joint, which they are not. Although no painted lime lines or additionally material is added on the surface of the ruled lines, the tightly compressed flat area of the Overhung Ridge joint typically dries lighter than the trailing and ruled edge which is scraped away to bleed into the surrounding texture of stone. This gives the appearance of a painted ribbon joint, but is not to say that in some instances pencylling was not still carried out. In Chestnut Hill, Philadelphia many original Overhung Ridge pointed buildings throughout Germantown Avenue and all the surrounding side streets can still be viewed.


The grapevine joint in stonework is a protruded bead. Easton, PA

Note to those in College Hill and the Easton, PA area: 1 part Ecologic™ Mortar G #DGM 200 (brown/grayish color) and 2lbs fine or medium grade slag flecks, (depending on the original mortar), is a good match for most mortar repointing work required on buildings built in this region before 1940.
Repointing of the entire Easton Cemetery Chapel, Easton, PA. The work included numbering, dismantle and re-setting sections of stonework. Mortar Mix: 1 part Ecologic™ Mortar G #DGM BLACK

This Landenberg, PA farmhouse was repointed and one large brick chimney was completely rebuilt. Color code DGM 50 Ecologic™ mortar. Stone joint style is "Brushed Back" using a wire duster tool.

Note- All the photos depicting Color code "DGM 50" is what can be used to replicate this off-white color that we have also called "Standard Cream Color" in the past. Everything required except water and mixing is already in a bag of Ecologic™ mortar. However, regular yellow mason's sand that meets ASTM C-144 specifications and NHL 3.5 could be mixed on site to also reproduce this color, or a shade very close to this color at a lesser cost. A mason can use yellow, brown, white or any other sand that meets ASTM C-144 specifications to achieve a similar hue to that of the sand color when using a Natural Hydraulic Lime as the binder.
