When using a sandblaster, what type of nozzle and pressure is recommended for cleaning?

The recommendation of using a 1/4" nozzle with a pressure range of 60-120 psi for sandblasting is grounded in the need for effective cleaning while minimizing damage to the underlying surface. A smaller nozzle size enables focused and efficient abrasive delivery, which is critical for achieving a thorough clean.

At 60-120 psi, the pressure is sufficient to propel the abrasive material effectively without causing excessive wear or harm to the surface being cleaned. This balance allows for the removal of contaminants like rust, paint, or other debris while maintaining the integrity of the underlying material, such as wood, metal, or masonry.

In various applications, too low of a pressure could result in ineffective cleaning, while too high of a pressure or using a larger nozzle could lead to surface damage, which is why this combination is optimal for residential and professional projects.
