Learn the basics of the SprayTechnique using Buddy Rhodes GFRC Blended Mix™.

The spray technique is accomplished in two stages: a surface layer (face/mist coat) without fiber, followed by a reinforcing layer (backer mix) containing AR Glass Fibers. The consistency of the sprayable mist coat should be similar to a milkshake. It should be fluid enough to move through a hopper gun, but not so fluid that it slumps down from vertical formwork. For the backer, you can make a fluid mix that pours over the mist coat, or you can make a thicker mix that is applied by hand. A thicker mix is especially useful for vertical walls. The key to the spray technique is making sure that there is good bonding between layers. Timing is critical. Before applying the backer mix, make sure that the mist coat has not fully dried out, but is firm enough that the backer mix won’t push through the surface and show fiber in your finished piece.

The process outlined in this video can also be followed when using Buddy Rhodes GFRC Admix in place of Blended Mix. Learn more about GFRC Admix here: https://www.buddyrhodes.com/gfrc-admi...
