Mixing glue into the plaster of Paris mixture will make it more durable and strong. Find out how to do this by reading the article that we have shared titled, how to make plaster of Paris stronger. We have shared the step-by-step methods on how to mix glue with the plaster. Where to Buy Hydrocal? What is a hydrostone? Hydrostone is considered the hardest and strongest plaster available. It is mainly used in tooling and art object applications. Hydrostone is a wear-resistant material and is designed for casting detail and strength. This material is 40 to 50 percent harder as compared to other casting plasters. Moreover, hydrocal works like plaster with regard to mixing, pouring and setting.

Pouring To prevent air entrainment and provide a uniform, smooth surface, careful pouring of the slurry is necessary. Agitation of the filled mold is a further step used to prevent air at or near the surface of the cast piece. Whenever possible, the slurry should be poured carefully in the deepest area so the slurry flows evenly across the surface of the mold. Most of the buildings in Hydrostone were built to minimize the dangers of fires, a consequence of the Halifax Explosion. Pouring a large amount of slurry directly on the face of the mold may result in slight densification of the cast at the point where the slurry strikes the surface of the mold.Soaking Sift or strew HYDRO-STONE Gypsum Cement into water slowly and evenly. Do not drop handfuls of HYDRO-STONE Gypsum Cement directly into the water. Allow soaking for 1-2 minutes. HYDRO-STONE Gypsum Cement should be fully dispersed in the water prior to mixing. Small batches require less soaking than large batches. See bulletin IG503 for specific soaking instructions.

Hydrocal is waterproof. Aside from that, it is also weatherproof and scratch-resistant. How to Make Plaster of Paris Stronger The best drying rooms or ovens provide (1) uniform and rapid circulation (minimum of 15-30 fps) of air with no “dead spots” Hydrostone is a type of plaster that is hard, strong, and has a high water absorption resistance. Its characteristics allow it to works well in plaster as well as in most flexible molding compounds. Hydrostone is usually used in making high-quality art projects and statuary castings. The slurry produced by this material has low viscosity and can be used for filling multiple molds at a time. How to Use Hydrostone Hydrocal provides twice the compressive strength of plaster and is ideal for thin and delicate sections where high green strength is needed.What is hydrocal? Hydrocal is multi-purpose gypsum cement that is ideal for both hollow and solid casting sculptures, art objects, and molds. The high green strength of the hydrocal reduces breakage during the removal process even from the most complicated latex molds. Proper mixing of hydrostone is a vital step to create casts that are strong and hard. As compared to other plasters and gypsum cement, hydrostone should not be mixed by hand and is recommended to be mixed mechanically. Furthermore, this type of plaster can only be mixed using a batch process. Having the right mixing equipment and mixing speeds are vital when mixing hydrostone. Step 5 – Pour another thing to consider is humidity and how much water the powder has absorbed makes some difference as well.
