A LimeWorks.us Mortar kit has the 9 stock colors of 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 9 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. deGruchy's 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.
