Residential floor sanding is needed for timber floors, in order to remove old and worn sealant and other coatings, and to buff down any dents, dings, and other such damage. Sanding is also done before you add a fresh layer of paint, if you want to change the appearance of the floors. While this job is best left to a professional, you might note some common questions and misconceptions about this work, so you have it done when needed and are sure to hire the right person for the job as well.
Many floor sanding companies will promise to use dust-free methods, and companies today will use bagged sanders that collect the vast majority of dust that is produced during sanding. However, there is rarely any method of sanding floors that is truly dust-free, and you may be asked to remove valuable knickknacks and cover upholstered furniture while floors are being sanded, to keep them from being damaged from any dust that cannot be collected. Be sure you understand this, and don't assume that paying more for a dust-free sanding will actually mean absolutely no dust in the home during this process.
The finish that is added to your timber floors after they've been sanded will affect their overall longevity, no matter their species. This is important to note, as some homeowners assume they can add a cheap or low-quality finish to the floors, in order to save money, if they have a dense species of wood installed on the floors. However, any species of wood will absorb moisture and be prone to scratches and scuffs, and needs a strong and durable finish for protection. Don't underestimate the importance of the finish you choose for your floors, but opt for something high-quality, so the timber lasts as long as possible.
Some homeowners wonder why they shouldn't sand their own floors, if they own a heavy-duty belt sander and are somewhat skilled in using tools. One considerations is that floor sanding is not only trickier than you might realize, but it's also downright dangerous! Sanding timber floors heats them up, and the dust that is produced is also flammable. Not being cautious about your sanding methods around a heating vent or open flame can then actually increase your risk of a house fire. The sanders used for floors also require a lot of electricity, and plugging them into an outlet that is not properly grounded can also increase the risk of an electrical fire. To avoid these risks, always leave this task to a professional.
