Pros

  • Easy to use and apply smoothly with a finger, making small repair jobs straightforward
  • Effectively fills and seals cracks, providing a strong and durable finish once dried
  • Dries quickly, allowing for faster project completion
  • Sands easily for a smooth finish after drying, especially useful on drywall repairs
  • High quality and reliable in performance when properly applied
  • Strong and durable crack repair, holding up well in most cases

Cons

  • The product can be tricky to dispense due to the nozzle design and thick consistency; sometimes the flow is rough or requires large punctures in the tube
  • Some tubes may arrive partially dried out or hard to use, which could be a batch issue
  • Flows poorly at first and might need a second application to achieve a smooth surface
  • Not intended for structural or stresearing cracks—limited to cosmetic or non-load cracks
  • Tends to shrink slightly after drying, so multiple layers might be necessary
  • Adhesive properties are not very strong, making it less sticky than some users expect
  • Applying too thickly isn't recommended since it dries hard and may crack later

Bottom Line

The 3M High Strength Crack Repair in the 7 oz squeeze tube is a solid choice for quick, strong crack filling on drywall and similar surfaces, especially if you want something easy to sand and fast-drying. However, expect some annoying dispensing challenges and keep in mind it’s not designed for structural repairs or larger stress cracks. If you're looking for better flow or stickiness, checking out other patching compounds might be worthwhile, but for typical home patch jobs, this is a dependable and well-reviewed option.
