                    How do you apply a new piece of sandpaper
                    ByDec 21, 2025
                    1 Answer | 
                    Answer This Question

                    Hello, Agar - To apply a new piece of sandpaper to the RYOBI A21C901 corner sander, first make sure the sander is powered off and unplugged for safety. Remove the old sandpaper by peeling it away from the pad, as most corner sanders use a hook-and-loop (Velcro) system. Inspect the sanding pad and clean off any dust or debris to ensure proper adhesion. Next, take the new sandpaper sheet and align its holes with the dust collection holes on the pad for efficient dust extraction. Press the sandpaper firmly onto the pad so it grips securely, and then check that it is flat and properly attached before turning the sander back on.

                      by
                      Effortless. Only needed to use two 120s and one 220 to sand off a dark stain finish on both sides of the entire bar, and go back to natural wood and a satin seal.

                      [This review was collected as part of a promotion.] Excellent weight in hand and strong performance, easy to use for long periods of time.

                        It works great!
                        [This review was collected as part of a promotion.] I have a wooden deck I built myself almost 40 years ago. It's still in great shape but there were a few spots where the semi-solid stain had bubbled up. The Ryobi 18V One+ Corner Cat Finish Sander worked great in removing and smoothing the old stain.The sander works great, replacing the sandpaper is super fast and holds reliably to the sander, and working from a battery rather than plugging it in is really nice. I also used my Ryobi drill and blower to help repair and clean the deck, and my Ryobi hedge trimmer to trim the shrubs around the deck. I have been very pleased with all my Ryobi tools.

                          Great tool, esp for smaller hands
                          [This review was collected as part of a promotion.] I bought this to help with the refinishing of my kitchen cupboards and love it! I also bought the connector piece to connect to the shop vac which if you are sanding indoors, I highly recommend! The sander works very well for what I’m doing. It feels good in my hand (I’m female, with smallish hands) and I don’t find a ton of vibration. I can sand quite a bit without any after-tingling like I find with our orbital sander. The only drawback is the not so easy task of getting more sandpaper. It seems I need to order it and have it delivered. And, there’s only variety packs of 3 pieces of 60/120/220. I’ll look more to see if that’s the only option. Otherwise, I do recommend this product.

                              Lightweight and efficient. Portability is great.
                              [This review was collected as part of a promotion.] I have several sanders. This one is perfect when uou need a light, compact, portable, and efficient sander. Recently, Notice was given by the local HOA the house needed to be repainted due to evidence of peeling paint. This lightweight sander was easy to use single handed while I was 16 feet up on a ladder. The peeling issue was resolved. The eaves were repainted and that was it. I would never have attempted this with my oscillating sander, or corded sander. This was perfect.

                                Great sander but should include vacuum attachment.
                                [This review was collected as part of a promotion.] So far I've really liked it, the quality to price ratio is excelent. The only thing I would change is it should definitely come with the vacuum attachment as mine did not. Also being able to change the speed would be nice but not entirely necessary. Between this and the stapler I've started to become a Ryobi fan.

                                    Bought this for a project. It is more powerful than I thought and did a great job. It can get into the little nooks and crannies and with the right sandpaper, make quick work of the project. It is easy to transport and since I have other Ryobi products i have batteries that can work with it.
