The SHEETROCK Brand Easy Sand 5 4.3 lb. Lightweight Setting-Type Joint Compound is ideal for patching drywall and plaster surfaces or for finishing drywall joints. With a convenient 5 minute set time, this compound is perfect for speedy projects.
Just as it is advertised, it sets up fast. I do miscellaneous sheet rock repairs for work and if you're patching holes, by the time you get finished patching you can almost sand right away. Mix small amounts because more often than not, it'll set up before you're done if you mix a full pan. I love this stuff. Fast fix. I'm in and out and on to the next job.
