Ecologic™ Mortar Product Description:
Mix and Go lime mortar based on NHL 3.5 pre-blended with sand (contains no Ordinary Portland Cement (OPC)) to be used for repointing and laying stone and brick.
Available in 12 stock colors and 3 different grades:
- Coarse(G) to be used for joints over 3/8″
- Fine (F) to be used for joints between 1/4”-3/8”
- Butter Joint to be used for joints under 1/4”
deGruchy’s Ecologic™ Mortar, in any of the stock colors, is simply a prepared blend of binder/aggregate/pigments to which you just add water, mix and go to work. Use it on historic buildings to re-point, stucco, parge, and plaster. Ecologic™ Lime Mortar can also be used to lay/re-lay brick, terra cotta, block and stone on modern construction. Ecologic™ Mortar is a “Green” Product and the result is an “Old World” Lime finish that is chemically and physically suitable as a replacement mortar for historic masonry.
Ecologic™ Mortar Benefits
The advantage of the pre-blended material with sand and pigment already added is that the quality control of the mix design is already completed. The mixing can take place on each level of the scaffold, if suitable conditions allow using the drill and paddle mixing method, with no excess sand piles or other bags of material stored on site.

deGruchy’s Ecologic™ pre-blended mortar is all you need. Having all the materials in one bag reduces the temptation to add Portland cement, which is customary when a typical Type N mortar is made with local hydrated lime. The pre-blended material ensures that the engineering of the mortar’s final properties is kept in a high-quality control environment with the right sand and the right pigments for consistent color and results.
NO Portland Cement is present or needed in deGruchy’s Ecologic™ Mortars yet the stock material will still reach the 750 p.s.i. 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™ Mortar is immune to sulfates and salts. The alkali-silica reaction does not take place with St. Astier Natural Hydraulic Limes.

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 Kit to see the actual color. By purchasing the cured mortar strips you may view each mortar sample in the case individually or hold one or more of these samples to the surface of the wall to ascertain which stock color may be most appropriate for your application.

I think it’s a good product. Since I’m not a mason, it was a bit of a learning curve to figure out the ratio of powdered mortar to water I needed, but I kept at it till the consistency seemed right. (I actually mixed it for 10 min since I added an additional 2 tablespoons of mortar to the mixture.) This was a small repair.
product was delivered on time as stated.
The color is right. I haven’t had a chance to use it yet (repointing 1949 brick veneer), looks promising.
Perfect for my project
