An Overview of Different Commercial Floor Sanders and Grinders

When completing concrete prep work or floor sanding, the type of floor grinder or sander used can make a huge difference in the quality and finish of a job. For a professional, the equipment used can make a big difference in customer satisfaction and profitability.

 

We're going to explain a couple of important differences in commercial flooring equipment and their impact on jobs.

Planetary Floor Grinder Versus Rotary Grinders

A planetary grinder is generally lighter, more maneuverable, and easier to use than a rotary floor grinder.

 

The rotary floor grinders are much heavier and bulkier than planetary. While their weight and size can result in rapid removal of multiple layers, and faster square meter rates, the downside is they demand a highly skilled operator to make the most out of them.

Multi-surface Grinder Versus Single Purpose Grinder

A multi-surface grinder can easily grind soft and hard surfaces such as wood and concrete. The reason for this is first that multiple tools can be placed on the grinding heads.

 

With systems such as Onfloor's patented quick-change tooling, this is quick and effortless. Secondly, there is a variable speed. Lower speeds are best for softer surfaces and higher settings for harder ones. This allows the multi-surface grinder to work equally well on wood, concrete, sealers, or stone.

 

With a product like Rustoleum's EZV Sander or Grind 'N Go, you would need two machines, one for wood and one for concrete, whereas with Onfloor's simple variable speed and quick change tooling, only one is needed.

Stand-alone Vacuum Versus Integral Vacuum

While a multi-surface grinder is a perfect utility tool, for cleaning up, a specific vacuum can be more useful. A machine like the Rustoleum Grind 'N Go has a vacuum attachment, but it is rather small, meaning that it needs frequent emptying. A larger vacuum will have better suction and reduce the time needed for emptying and refilling.

Size Matters

When looking for a grinder, if you're normally completing small residential jobs, then a small grinder is best, since it will be transportable, and easy to maneuver in small indoor spaces, and may reduce the need for an edge grinder. However, if you are completing regular large commercial jobs, then speed or cover will precede maneuverability, and a larger grinder will work out far better.

 

A larger machine can provide significantly better square meter rates, for example, the Onfloor OF16S-H can complete up to 300 square feet per hour. However, the slightly larger OF20S-H can complete up to 500 square feet per hour, which makes a big difference to your productivity.

Other Options to Consider

The other options to consider when looking at a commercial floor grinder or sander, is maximum speed, whether it can complete wet and dry jobs, the manufacturer's quality score, and the availability of after-sales service.

Summary of Commercial

There is a lot of research needed before making an investment in these incredibly versatile and useful construction tools. If the options are still relatively confusing, it’s best to seek the help of a professional.
