How to Use a Texture Spray Gun
A texture spray gun is the tool you’ll need in order to spray on drywall compound, or you can use it for textured paint. It requires a special spray gun, and lots of care, because both of these are very messy to put on walls and ceilings. You can buy a texture spray gun if it’s something you’re going to use often. Otherwise, you’ll save money by renting one whenever you need it.
Step 1 - Preparation
The job will proceed more smoothly if you’re able to move everything out of the room. If you can’t do that, make sure the items are completely covered by drop cloths. Put drop cloths over the entire floor and mask the ceilings and doors with plastic and making tape. Do the same for any baseboards, vents, and electrical outlets.
For your own protection, always wear a dust mask and safety goggles. You’ll find cleaning up later to be much easier if you cover your hair with a cap and you should always wear old clothes that you can just discard after.
Step 2 - Mixing
Mix the drywall compound with water in a bucket. Follow the instructions exactly for the proper consistency. If you use a power mixer attachment on a drill you’ll be able to achieve the best consistency for the texture. Take your time over this, as lumps will simply clog the nozzle on the texture spray gun and you’ll need to keep stopping to clear them.
Step 3 - Spraying
If you don’t have experience in using a texture spray gun, it’s advisable to take time to become familiar with one first. Practice beforehand on an old piece of plywood to achieve the best results and to learn how to operate the texture spray gun.
Step 3 - Applying Texture
Put the well-mixed textured compound into the hopper of the texture spray gun. Put on your mask, safety goggles and cap. Stand about 3 to 4 feet away from the wall you intend to spray.
Press the trigger and begin to spray. You’ll find it best to start at the top of a wall and gradually work your way down to the bottom. Move the nozzle from side to side, and keep stopping to check for complete coverage with no bare spots. With a ceiling, work from a stepladder, being sure to take all the proper precautions for your own safety. Work back and forth across the ceiling, starting from one corner and moving outward. The safety goggles are vital for this job.
Step 4 - Finishing
In some place the texture will be thicker than you want. Remove the excess with a knife, but be careful not to smooth the texture spray out too much. Allow the texture ample time to dry before you begin to clean up the room.
