Abstract
A concrete-based mortar is prepared for application on the exterior of a concrete building or other structure. The drying time of the concrete-based mortar is reduced by addition of an accelerant compound. After the concrete-based mortar sets on the building or other structure, an exterior skin of the concrete-based mortar is removed. This provides an even and attractive surface while reducing the amount of labor time required to complete the application.
Claims4
A method of applying a concrete-based mortar to a building comprising the steps of:
- mixing a concrete-based mortar, an accelerant and water to form a resulting composition that hardens in approximately three hours time or less;
- applying the resulting composition to an exterior of a building;
- allowing the resulting composition to harden on the building for a time sufficient to prevent reformation of the composition;
- and
- removing an exterior skin of the resulting composition after the step of allowing the resulting composition to set, wherein the step of removing the exterior skin of the resulting composition comprises scraping a rough trowel against the resulting composition to remove only the exterior skin, wherein the resulting composition has hardened sufficient to prevent uneven scraping and has hardened sufficient to prevent sticking to the rough trowel, and wherein the resulting composition has a smooth and even surface after the step of removing the exterior skin.

- mixing a concrete-based mortar, an accelerant and water to form a resulting composition that hardens in approximately three hours time or less;
- applying the resulting composition to an exterior of a building;
- scraping the resulting composition with a rough trowel to remove only an exterior skin from the resulting composition and to leave a smooth and even surface;
- and
- allowing the resulting composition to harden, after the step of applying the resulting composition and before the step of scraping the resulting composition, for a time sufficient:
- (a) to prevent reformation of the resulting composition;
- (b) to prevent uneven scraping of the resulting composition by the rough trowel;
- and (c) to prevent any of the resulting composition from sticking to the rough trowel.
