Question: I have stained/sealed concrete floors. All I need is to rent us a buffer and use the product listed? Answer: The machine you need is a "low speed buffer", which are typically around 175 rpm and available at most any rental store in a 17" or 20" size. The most common size buffer is the 17", which our 16" satellite pads fit underneath well. If you're prepping for stained concrete, you would want our 30 grit pad. We talk a lot more about the process on our comprehensive page for "stained concrete". We have a water based stain and an acrylic based stain for concrete floors. https://concretefloorsupply.com/u-stain-systems/ [youtube https://www.youtube.com/watch?v=w0kGVxNoANk&w=560&h=315] Follow us on Facebook!
