Casting Gypsum Plaster

Gypsum plaster, also called white cement, is a material made primarily of the mineral gypsum in combination with chemicals that make it easier to work with like retardants. When mixed with water, the plaster turns into a plastic state that can be moulded and formed. It then sets and hardens as the gypsum absorbs the water.

Gypsum plaster is often found in the construction industry, where it has been used for several hundred years as an adhesive, structural material and to create decorative coving and sculptures. Here at Barnes Products, we have various gypsum plaster products for all your latest crafts. Browse our range online today.

Gypsum plaster uses for hobbyists

One of the main uses of gypsum plaster by hobbyists is for casting. Gypsum can be used to create a durable mould for casting other materials or the plaster itself can be poured into a mould. Casting gypsum instead of other cement plasters has some advantages:

  • No shrinkage cracks — Gypsum reactions produce less heat compared to other types of cement, which is why gypsum plaster products have fewer cracks — giving you a great looking finish.

  • Fast-setting and drying — Within half an hour of pouring, the plaster will have set and will be dry enough to paint on within 72 hours.

  • Lightweight and durable — While gypsum is incredibly light, it is still extremely durable and strong.

  • Smooth finish — When casting gypsum you can achieve a much smoother finish than you would with other types of cement — making it perfect for sculptures, reliefs and busts.

Gypsum plaster uses are limited in damp areas because the plaster can retain moisture. This means the plaster is not suitable for sculptures in the bathroom or garden where it will frequently be exposed to rain or high humidity.
