A concrete gun uses compressed air to project cement or concrete at high speed onto building surfaces. It has two basic processes: dry and wet applications. The process is flexible and used in construction projects ranging from high-rise buildings to swimming pools. Cement spraying applications fall into two categories: dry mixing and wet mixing. Both types of cement guns consist of a large hopper, air pumps, hoses, and nozzles.
A concrete gun is a machine that uses compressed air to project a stream of cement or concrete onto building surfaces at high speed. Pressure gun cement applications consist of two different basic processes: dry and wet applications. Concrete gun techniques allow for the rapid application of large quantities of structural or non-structural concrete to both vertical and horizontal surfaces. Many decorative grout applications are also possible with a cement gun due to its ability to project slurry at high speed onto vertical surfaces. A cement gun typically consists of a large hopper into which the cement mix is added, a cement hose and, depending on the type of process, a separate water hose.
Also known as gunite or shotcrete, the cement gun process was originally developed as a method for applying plaster slurry to taxidermied models by Carl Akeley in the early 1900s. The process is quite flexible and well suited to the application of simple cement-sand mixtures or structural concrete aggregates. The concrete gun process is used extensively in construction projects ranging in size from large high-rise commercial buildings to residential swimming pools and remodeling projects. The high-speed spraying involved in the process allows mortar mixes to be sprayed onto exterior surfaces at all angles, including overhead applications. This makes decorative procedures such as building rock features and applying textured wall coverings a quick and easy affair.
Cement spraying applications fall into two basic categories and each with distinct benefits. The first is a dry mixing method in which a dry mixture of cement and sand is projected down the concrete pipe and mixed with water as it exits the nozzle. The mixing process of the dry components and water then takes place upon impact with the coated surface. Cement gun dry mixing processes allow for precise control of the consistency of the mix because the nozzle can constantly regulate the flow of water during application. This process is especially useful for repair work and decorative coatings.
The job of spraying wet mix concrete involves applying pre-mixed concrete aggregate under pressure. The machinery and techniques used are similar to dry mix, although wet mix applications are more suited to structural work such as flooring, joists and pool liners. Both wet and dry cement guns typically consist of a large hopper used to hold the cement mix, cement, and air pumps and hoses and nozzles that propel the mixes.
