### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works Great!
  

*by R***G on Reviewed in the United States on June 18, 2020*

I have been using U.S. Gypsum's Hydrocal for the past 50+ years to do basic scenery and rock castings on my model railroads.  It's easy to use and is stronger than Plaster of Paris.  I can mix it to various consistencies depending on the actual job I am doing and it sets up pure white, ready for stain.  The box I received from the Plaster Guys was stuffed tight - literally.  The contents were fresh and everything worked as it should. Thanks!

    This is definitely plaster. The cops checked.
  

*by S***. on Reviewed in the United States on June 11, 2020*

It looked ugly when it arrived. The box was all deformed but it had a bag of plaster inside so it didn't really matter. The bag was not punctured.The plaster works great for crafting and is forgiving if you don't measure it exactly.You shouldn't put it into smaller pre measured baggies and transport it in a box on the front seat of your car. The cop didn't take my word for it that it wasn't cocaine. Awkward.

    Perfect for my Castings
  

*by A***A on Reviewed in the United States on March 29, 2021*

Prompt reply from The Plaster Guys to my query. Package arrived quickly and the powder was packed to the brim! The powder is definitely 'fresh' as setting times are according the manufacturer's guidelines. Will be purchasing more soon as I've almost gone through my 25lb bag!
