If you are after a polymer reinforced plaster we can offer you 3 options;
Crystacal Lamina Plaster; is a plaster with a powdered acrylic polymer content. So you just use it like a normal plaster and only mix it with water, but it produce a plaster that is much harder and stronger than most plasters.
Plaster Polymer; is a liquid acrylic polymer that you add to plaster instead of water. It is best used with Crystacal R Plaster and mixed 2.5:1, Plaster: Polymer, however it can be used with other plaster and the polymer can also be watered down to make it more cost effective.
