Quick Answer
Ensure a proper seal when blowing in cellulose by using a quality blower with adjustable pressure settings, maintaining a consistent flow rate, and working in small sections to prevent settling or gaps.
Choosing the Right Blower
When selecting a blower for cellulose insulation, look for a machine with adjustable pressure settings and a consistent flow rate. A blower that can produce 1,000 CFM (cubic feet per minute) or more is suitable for most applications. Some popular blower options include the Celect 300 or the Cellulose Insulation Blower.
Preparation is Key
Before blowing in cellulose, ensure the area is well-ventilated and free from obstructions. Remove any electrical components, outlets, or switches to prevent cellulose from accumulating in these areas. Use a dust mask or respirator to prevent inhalation of cellulose particles. It’s also essential to maintain a consistent flow rate to prevent settling or gaps. For optimal results, keep the blower’s pressure setting between 5-10 PSI, and maintain a distance of 12-18 inches between the nozzle and the wall.
Tips for a Proper Seal
To ensure a tight seal, work in small sections, typically 4-6 square feet at a time. Use a sealant, such as caulk or spray foam, to fill any gaps or cracks in the wall before blowing in cellulose. For particularly difficult areas, such as corners or around windows, use a specialized nozzle or extension tube to direct the cellulose flow. By following these guidelines, you can achieve a proper seal and maximize the insulating performance of your cellulose installation.
