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