Revival Flooring uses a Dust containment system upon request.  This system stops about 90% of the dust from becoming airborne creating a cleaner environment.  Even though this system is effective, it still doesn't stop all of the dust.  Some floors also well don't allow us to use this system.  An example of this is a pine subfloor refinish.  Due to gaps between boards and the uneven characteristics of the flooring, the dust containment system is not effective on a floor of that nature.  In any event, our up to date machines work very well on there own to trap the dust.
