Notice: The SurfPrep Sanding System is designed to work as a complete system whereby SurfPrep branded sanders connect to and operate with SurfPrep branded dust extractors. Customers have successfully connected SurfPrep sanders to other brands of dust extractors without incident of static electricity and maintain full functionality of auto on/off features. SurfPrep sanders can easily connect to DIY STYLED vacuums with parts we provide. However, in these cases SurfPrep DOES NOT guarantee freedom from static electric shock. Often this occurs when lower priced DIY vacuums do not have the appropriate grounding components to prevent static shock. SurfPrep fabricates all sanders & dust extractors with static conductive components.

Great for Cabinet Refinishers

I've used the 3" X 4" SurfPrep Sanding System for every kitchen remodel. I love to use it for finishing in-between coats. The 3mm orbit and rectangular shape is great for sanding into corners and mouldings.

Victorian House Restoration

I bought this kit to help me restore a historic victorian house with painted trim that I wanted to strip and refinish in a stain. This is not great at stripping but it is very helpful in the finish process when you have paint in the wood grain or need to sand out marks. I have found a lot of uses and it has made me much faster at those tedious sanding tasks.

Great Abrasive Pads!

I know that most people use these for woodworking. However, I run a Powder Coating business and I use these all of the time. I have the Surf Prep 3x4 sander and using these pads, especially on thin steel and aluminum, they make my prep work easy. I don't have to worry about the metal warping when use my Surf Prep. Great Products!

Over the last 40+ years I’ve used countless brands of sanding products

Over the last 40+ years I’ve used countless brands of sanding products, Surf Prep has out preformed any of them. It cost me more up front, but the cost per use is considerably less, since the longevity, and performance is so
good.

The quality of the hooks are top notch

The quality of the hooks are top notch. They have a higher than normal melting point meaning you can get a lot of detail sanding in without worry of replacing hooks. I mean they do sell intermediate pads, but come on we're in a hurry and not always going to be having them handy on the job site!

Just like their sanding pads for cabinets these disk are great. It makes drywall work a breeze and uses less disk than my old product

Where have you been my whole life?!

I've been woodworking for over 14 years and I was clearly missing the memo for too long! These pads actually make sanding enjoyable. I got all the different thicknesses for these and I'm in love with them all. Now I need to make a storage area for more boxes 🤣
