The hopper gun is a great tool for spraying vinyl chips onto vertical surfaces — I always recommend using one for our Dur-A-Wall™ VC system. The hopper gun reduces the blotchy look created by hand tossing and saves wear and tear on the body.
A few tips when using a hopper gun:
- Maintain the pressure in the compressor at around 25-30 psi and be careful not to get too close to the wall – high pressure and/or getting too close can break the chips and make them bounce off the surface
- Keep the nozzle attached when spraying cove
- Remove the nozzle when spraying wall surfaces so the chips spray in a wider pattern and move the hopper in a circular pattern for a more uniform look
- When spraying macro chips avoid filling the hopper completely as they have a tendency to clog
