Drywall Sprayers are responsible for applying drywall to walls and ceilings using a spray gun. They must be able to work independently and as part of a team, and have a strong attention to detail. Key responsibilities include:

1. Prepare surfaces for drywall application

This includes cleaning the surface, removing any debris, and applying a primer.

2. Install drywall panels

This involves cutting the drywall to the correct size and shape, and then attaching it to the surface using nails or screws.

3. Apply joint compound

This is used to fill in the joints between the drywall panels and to smooth out the surface.

4. Sand and finish the drywall

This is done to create a smooth and even surface that is ready for painting or wallpapering.
