Did You Know?

1. Sanding wooden floors can be traced back to ancient Egypt, where archaeologists have found evidence of sanding tools used as early as 1500 BCE.
2. Did you know that the first electric floor sander was patented in 1912 by a man named Otto Hetzel? This invention revolutionized the sanding process by eliminating the need for manual labor and allowing for a faster and more efficient sanding job.
3. If you’ve ever wondered why sandpaper is referred to by its “grit” value, it’s because the roughness or coarseness of sandpaper is actually determined by the size of the abrasive particles embedded in the paper. The higher the grit number, the finer the sandpaper and the smoother the finish it provides.
4. For a truly unique and eye-catching floor design, some homeowners opt for the technique known as “parquet flooring.” This intricate style involves arranging small wooden blocks or tiles in geometric patterns, making a visually stunning statement in any space.
5. Sanding floors requires great care and precision, but did you know that there is an entire art form dedicated to using sand as a medium? Sand art is a technique where artists create breathtaking sculptures or intricate designs using colored sand. This creative endeavor demonstrates the versatility and beauty of sand in various forms.

Prepare The Room And Protect Surfaces

When embarking on the task of sanding floors, it is crucial to begin by removing everything from the room. This includes furniture, rugs, and any other items that may hinder the sanding process. By clearing out the space completely, you ensure that all areas of the floor can be accessed without any obstructions.

Once the room is empty, it is important to vacuum the floor thoroughly. This step ensures that any loose dirt, dust, or debris is removed before the sanding process begins. A clean surface is essential for achieving a smooth and even finish.

Additionally, it is imperative to protect any light fixtures in the room. Sanding floors can create a significant amount of dust, which can settle onto fixtures and potentially cause damage. To avoid this, cover the light fixtures with plastic sheeting or an old cloth.
