Looking to buy or sell used concrete surface prep equipment? This is a free, no-pressure board where our community of contractors can connect — find a quality used machine, or sell one you no longer need. Buyers and sellers deal directly.

Selling Your Equipment?

Have a Prep/Master®, grinder, shot blaster, or other surface prep equipment to sell? List it here free. Send us the details and we’ll post it for fellow contractors to see — you deal directly with the buyer, on your terms.

To list your equipment, send us:

• What it is (make, model, year if known)
• Condition and hours, if known
• Your asking price
• A few photos
• Your contact info (how buyers should reach you)

Email the details to cindy@substratetechnology.com or call (815) 941-4800 x 1, and we’ll get it posted.

Looking for Equipment We Sell Directly?

We also offer new equipment and shop-inspected used machines that we stand behind. See our used equipment, machines, and Prep/Master grinders.

Substrate Technology provides these listings as a free courtesy to connect buyers and sellers. We are not a party to any transaction. Listings are submitted by the seller, and we do not inspect, verify, warranty, or guarantee any equipment, its condition, or any claims made. All sales are strictly between buyer and seller, as-is. Buyers should inspect equipment before purchasing.
