For small texturing projects, such as spraying a popcorn texture on a ceiling, a compressor with a tank size of around 20 gallons and a CFM (cubic feet per minute) rating of 5-7 should suffice. This type of compressor is typically portable and can be easily moved around the job site.
For larger projects or for spraying heavier texture materials, such as knockdown texture or sand texture, a larger compressor with a tank size of around 60 gallons and a CFM rating of 10-12 is recommended. These compressors are more powerful and can handle the higher air demand required for spraying thicker materials.
It's important to ensure that the air compressor has enough CFM to support the spray gun being used. The CFM requirement of a spray gun is typically specified in the manufacturer's instructions. If the compressor does not have sufficient CFM, the spray gun will not be able to atomize the texture material properly, resulting in a poor-quality finish.
Additionally, the air compressor should be equipped with a water filter to remove moisture from the air supply. Moisture in the air can cause the texture material to bubble or spatter, resulting in an uneven finish. A properly filtered air supply will ensure a smooth and professional-looking finish.
When using an air compressor for spraying texture, it's also important to follow safety precautions, such as wearing appropriate safety gear, maintaining a clean work area, and ensuring proper ventilation.
