Works great for patching walls
If you ever think about doing any sort drywall patching, having this stuff is a must.  I always find myself needing to fill holes in drywall, prep for painting a room or needing to repair a hole in a wall. Recently, my son was standing on the shelves in the pantry and they couldn't support his weight.  As soon as I heard the crashing in the kitchen, I knew we need to repair the drywall. Fortunately, we always keep Plaster of Paris on hand in our house.  The best part about Plaster of Paris is the fact that it doesn't dry up, because it's powder. Whenever you need to patch some drywall, go mix it with some water and have at it!

      You better be fast to use this
      You better be able to mix it and apply it within 8 minutes or it goes hard, and it is unusable. I would not buy this product again.
      Response from DAPProductExpertDec 20, 2021
      Thank you for posting your feedback. DAP Plaster of Paris (as with all similar Plaster of Paris formulas) are designed for rapid setting. As indicated on the product package label: "Add DAP Plaster of Paris to clean water in a clean container mixing 2 parts powder to 1 part cold water (40°F to 50°F). Stir to a smooth consistency. Do not mix more material than can be used in 6 to 10 minutes. Discard any material that has begun to harden. As soon as the powder and water make contact, the product's chemical reaction begins. For this reason, the 6 - 10 minute working time referenced, includes the time required to mix the product for use. For repairs requiring a longer work time (over 6 - 10 minutes), we recommend the use of DAP Plaster Wall Patch. Should you require additional assistance or have any other questions, please contact DAP’s Technical Customer Service Department at 888-327-8477. DAP

            Crumbled far too easy. Not good for mold making or for the projects I used it for. Honestly I was looking for ultra cal 30 or hyrdrocal, and this plaster didn’t even come close. This stuff is better used for small projects and children.

            Thank you for posting your feedback. We're sorry to see your low star review on DAP Plaster of Paris. Based on your commentary indicating: "Because you did not provide any background or details about your attempted use of this product, it Crumbled far too easy.", it woudl appear that the dry plaster powder to water was off ratio. Off ratio mixes will result in low strength is difficult to provide a proper response in this format. At your convenience, please contact DAP’s Technical Customer Service Department at 888-327-8477 so that we can obtain some additional information from you and to offer some additional application guidance.
