What Is A Gunite Projection Machine And How Does It Work?

The gunite projection machine is a device that projects an image into the ground without using any conventional light source. It works on the principle of gunite, which is a mixture of water and cement used in construction to give a smooth surface. Gunite is a type of extruded polyurethane used as a sealant and coating material. It is a two-component system consisting of an epoxy resin and a urethane hardener. The system cures under heat and pressure, forming a strong, durable finish.

The gunite process begins by preparing the substrate. This can be anything from a piece of metal to a concrete slab. The substrate is then coated with the gunite mixture using spraying machines for gunites. The mixture will be applied in a pattern to create the desired surface. After the mixture has been applied, the substrate is placed in an oven and heated to 150 degrees Fahrenheit. This will cure the gunite and form a tough finish.

There are several types of gunite projectors available on the market today, each with its own unique features. Here are just a few examples:

Roto Gunite: This machine uses rotating drums to apply the gunite mixture. It is perfect for applications that require large areas to be covered quickly, such as swimming pools or racetracks.

Air Gunite: This machine uses compressed air to apply the gunite mixture. It is perfect for applications that require small areas to be covered quickly, such as building foundations.

Water Gunite: This machine uses water to apply the gunite mixture. This is the best all-around gunite application for applications that require both large and small areas to be covered.

Common Uses for GPMs:

  • Creating signs and graphics
  • Creating wall and ceiling designs
  • Creating logos and labels
