Does the Home Depot Tool Rental shop offer a sandblaster rental?
When I checked out the main Home Depot tool rental site, they didn’t list it in either the “Professional Contractor” or the “Do It Yourselfer” section. I haven’t seen them offer blasters in a while either and it might depend on each particular Home Depot store.
You can try calling them at 1-800-430-3376 and ask if they have it at your store.
They also offer pressure washers for rent and there may be an attachment that you can use to convert it into a pressure washer blaster. This basically sprays high pressure water with abrasive media mixed into the water.
If you have any questions, leave a comment below. Also, I wrote up a post before about sandblaster rental information.
