True dustless hardwood floor refinishing should really be recognized as a restoration. Floors are sanded to bare wood removing the old finish, deep scratches and stains leaving the old wood to appear as new again. Once new stain color and floor finish is applied, the result is a restored or for the point of this blog a Refinish Hardwood Floors. While searching for dustless hardwood floor refinishing, one will find different phraseology about the process making the decision on who to hire confusing. The biggest play on words pertains to dustless floor refinishing because nobody wants their house to get covered in toxic dust. Since the invention of the floor sanding machine, the normal was to tie a dust collection bag on the machines exhaust pipe; the exhaust blower fan would then blow the dust into the bag. This is not a vacuum like some will tell you, and is terribly inefficient. I am a 30 year veteran of the wood floor refinishing industry and here are the facts.
DustLess floor refinishing is accomplished by removing the machines dust collection bag, and attaching hoses to which the other end is connected to a vacuum. The concept is simple and can work better than your expectations. Truck mounted equipment is superior to portable vacuums because they are more powerful; and the power of the system is crucial to get the proper results. Professional truck mounted equipment like ours can be powered by up to 27 horse power gasoline engines; whereas portable 110V vacuums that plug into the wall are only up to 1.5 hp. There is no comparison and the portable systems are just a way for someone to claim dust free bragging rights; they don't work because they are nothing more than glorified shop vacs. Dustless floor refinishing is now in the industries spotlight, and is separating the men from the boys. Beware of this and make sure the contractor you hire has made the investment in proper equipment before you make an investment in them.
Sand-Less is exactly what is says. There is no sanding to bare wood so there obviously is no saw dust to worry about...but, your floors are not being restored. Typically the sand-less method includes what's called wet burnishing. They place an abrasives disk like a screen or wet 3M scrubbing pad under a waxing machine and run it over the surface of the floor. Sometimes mineral spirit is used to remove wax dirt, or residual build up from cleaning products like Murphy's Oil Soap. Once the surface is prepared they tint the finish a color you select and apply it to the floor. The bottom line is you're getting a good cleaning and a re-coat of tinted finish. I personally haven't met anybody that has been happy with the service. In fact, I get the calls from irate people who wasted their money and want to have their floors restored properly. The usual complaints are: The finish peels, the floor slats are not flat, scratches or stains in the wood itself were not removed, the finish is cloudy, and the floors don't look new. Frankly, I don't understand how anyone can not realize the difference between a full blown floor sanding and this so- called Sand-Less method, so I have tried to make it perfectly clear. Beware!!!
