We get a ton of enquiries from customers about replacing sanding discs on their sanders. Most of the time, they are looking for new hook material to attach to their sander because the old hook has finally worn out after repeated use. We've got a few options available for replacing the hook on your disc sanders.
What is a Hook and Loop Sandpaper Disc?
A hook and loop sandpaper disc is a circular abrasive disc that attaches to a power sander using a hook and loop system, similar to Velcro. The sander base has a "hook" surface, and the sanding disc has a "loop" backing. This design allows for quick disc changes, a secure hold during sanding, and reusability. These discs are commonly used in woodworking, metalworking, and automotive refinishing.
How to Attach Hook and Loop Sandpaper Disc?
Attaching a hook and loop sandpaper disc is easy:
- Clean the sander's hook surface to remove dust and old adhesive.
- Align the holes on the disc with the sander's dust collection ports (if applicable).
- Press the loop-backed sandpaper firmly onto the sander base.
- Ensure full contact with no air pockets for smooth operation.
Once secured, the disc stays in place during use and can be removed and reused until worn out.
Replacement Hook Options
We carry a variety of products to help you replace or restore the hook surface.
6" Black Hook Sew On
Our DuraGrip Brand 6" Sew On Hook is great if you need a lot of hook for several sanders and you want to apply your own adhesive to secure it in place. This product is sold on 25 yard rolls and we can even cut the roll to length for you and ship you the cut pieces in a bag.
6" Black Hook with Adhesive Backing
This is another great option. This hook product has an adhesive backing so the material can be cut to size and then just remove the release liner and press the hook to the base of your sander. The rubber adhesive is good up to 190F and bonds well to a variety of substrates. This adhesive does not hold up well long-term to moisture or chemical use. There is also an acrylic adhesive option available as wide as 4" which holds up better to wet conditions and chemicals. These are also sold on a 25 yard roll and can be cut to length for free.
By The Yard
A lot of the time, customers only need enough hook to cover a single sanding disc. We can help with that too! We sell our 6" Black Hook with Rubber Adhesive by the yard! You can get a 3 foot long piece for just a fraction of the price of a 25 yard roll. You can cut this yard down to size to make sure it fits your disc sander perfectly and you'll still have enough left over to save for future use.
VELCRO® Brand Fasteners
We also carry VELCRO® Brand hook and loop as wide as 4" that can help to cover your sanding discs. The adhesive-backed options are available in a rubber and acrylic-based adhesive. The acrylic adhesive is particularly useful if the application requires a lot of moisture or extreme temperatures.
If you have any questions about your specific application, we're always happy to help! You can call us at (800) 940-6934 or email us at info@hookandloop.com.
Additional FAQs:
Q. How to apply hook and loop sandpaper?
A. Clean the hook surface, align the sanding disc properly, and press down evenly to ensure a strong grip.
Q. Why won’t my hook and loop sandpaper stick?
A. The hook surface may be worn or dirty. Clean it thoroughly or replace the worn hook material with fresh adhesive-backed hook tape.
Q. Why does my sanding disc keep falling off?
Possible reasons:
- Debris or dust on the hook base
- Worn out hooks or loops
- Low-quality adhesive or incorrect alignment
- Replace the hook surface if it's degraded.
Q. Why does hook and loop sandpaper have holes?
A. The holes align with the sander's dust collection system to remove debris while sanding. This reduces clogging and improves efficiency.
Q. Is hook and loop sandpaper reusable?
A. Yes—if the abrasive surface is still good, the disc can be reused multiple times. Just remove it carefully and store flat between uses.
