Efficiently Placing Vertical, Hand-Applied Mortar

---

Vertical/overhead repair mortars are traditionally hand- or spray-applied. Small repairs are suitable for hand application; whereas, low pressure spray equipment is useful for large projects. Mortar guns are commonly used for tuckpointing applications using site-mixed, masonry mortar. As most vertical/overhead concrete repair materials exhibit a stiff consistency, such mortar guns have not been widely implemented in concrete repair applications. With its unique, thixotropic rheology, MasterEmaco N 425 is well suited for use with such equipment. This demonstration presents the ease of application of MasterEmaco N 425 using a Quikpoint 3000 mortar gun.

Objectives

1. Demonstrate the proper equipment required. 
2. Illustrate how the method can be used. 
3. Identify the types of mortars used in this application. 
4. Compare the timing of this method vs traditional hand-applied applications.
