When using a floor sander, perhaps the greatest danger is that you will leave the imprint or marks from the sander all over your floor. The bulk and weight of this machine are the major culprits with this particular problem.
It is nearly impossible for the amateur to manage this task without leaving some kind of mark; even professionals have some degree of difficulty preventing any and all marks from their sanders. These marks are often referred to as ‘chatter marks’.
While it isn’t easy to prevent these marks, taking the following precautions before sanding the floor can go a long way towards preventing these problematic chatter marks. First of all, if the floor is already stained it will require different sanding procedures than a floor that is unfinished.
Applying a blonde finish (a finish directly to the wood) doesn’t require quite the intensive sanding that staining wood will require. It is highly recommended that if you plan to stain your wood floors you seek the services of a professional for the sanding.
You should also consider the virtues of a professional floor refinisher is the home you are working on has really old floors. One of those reasons being that it is hard for the novice floor sander to identify exactly which type of equipment would be best suited to the job where a professional would know this information and avoid potential damage to your floor by selecting the wrong sander.
If you choose a sander that is too powerful for your floors, you could very well end up with holes in your floors and a need for a new floor rather than simply refinishing the floor.
Another good reason to hire a professional when it comes to sanding your hardwood floors is that professional grade floor sanders are not exactly inexpensive and most people can’t just go out and rent them. Professionals mock even those rental units that are referred to as professional grade by the rental companies as ‘toy sanders’.
They simply lack the weight and power to accomplish the job at hand in any reasonable time frame. These sanders are also quite rough on the back, wrists, neck, and nerves. Trying a job of this proportion without the proper tools is simply put, a bad idea.
You might be amazed at the fact that you can quite possibly hire a professional the first time around and save money on the project by having things done right the first time. However, if your purpose is to simply refinish a small area (less than 600 square feet) rather than an entire home, you may find it worth it to rent a floor sander and do the work yourself.
