Using drywall texture sprayers to get a knock down texture is simple. Unlike other types of texturing methods, the knock down texture is applied unevenly, making it very simple for anyone to do. Other than the standard dry wall mixture and tools, you simply need to rent a portable texture sprayer. These can be rented at any home improvement store by the hour or day. If you are texturing a large room, allow at least 6 hours of machine use. It's actually more advisable to just rent it for an entire day.

Step 1 - Clear the Room

Working with a drywall sprayer is a messy job. No matter how careful you are, you will still likely end up with flakes of drywall on anything left in the room. Go ahead and clear all furniture out of the room. Use drop cloths to protect the floor, and make sure you have proper clothing and eye protection before you start. 

Step 2 - Mix the Compound

You can use any type of drywall compound for this job. You will just need to follow the directions for mixing the compound provided by the manufacturer. Most often you will mix the compound in a bucket with water until you get the right consistency. It will need to be thinner than normal since you are using a sprayer.

Step 3 - Start with a Test Patch

Drywall takes only 15 minutes to dry, so you want to test the method in a small area before you embark on the whole room. This will give you an idea of how much you can spray and still trowel in less than 15 minutes. Spray a small area with even strokes. Allow a few minutes for the mix to get sticky, and use a trowel to create the uneven patterns. Once you have gotten the hang of it you can work on larger sections in the room.

Step 4 - Apply All Around

You still want to work in small patches since it will dry quickly. Start at the top of the wall and move slowly and evenly in a downward direction. Stop every few minutes to create the texture desired with the trowel. It's a good idea to keep the trowel at a 45 degree angle. This will prevent you from flattening the coat, giving you more of a textured surface without creating too many peaks.

Step 5 - Dry Time

Even though it only takes about 15 minutes to dry, you want to give it at least 24 hours before you bring anything back in the room. After this you can prepare the wall for paint by priming it.
