Very hard, ready-to-use polymer gypsum HandiCast (65 MPa)

Very hard, ready-to-use HandiCast polymer gypsum (65 MPa). Ideal for precise mould surface mapping. Reduce process time with ready-to-use gypsum mix.

Colour: grey-beige.

Product description - HandiCast polymer gypsum (65 MPa):

Polymer casting gypsum with exceptional hardness and mechanical strength. A ready-to-use gypsum mixture that provides accurate mold surface mapping without the formation of crusts and pins. HandiCast polymer gypsum (65 MPa) reduces process time by eliminating the need to select ingredients.

Composition and characteristics of HandiCast polymer gypsum:

The mixture consists of high-strength gypsum, acrylic polymers, mineral fillers and modifying additives. HandiCast polymer gypsum is a homogeneously mixed, ready-to-use, dry mixture with a light grey colour. Thanks to its ingredients, HandiCast gypsum contains no harmful substances and is suitable for casting without the use of a vibrating table.

Application and parameters of HandiCast gypsum (65 MPa):

This HandiCast polymer gypsum is perfect for sculptures, 3D gypsum panels, decorations with complex shapes and garden and park architecture. HandiCast gypsum ensures optimum process time and eliminates problems associated with dosing ingredients.

The setting time is 40-90 minutes.

Compressive strength after 72h: ~65 MPa.

Water-gypsum ratio - 25/100

(The amount of water quoted is approximate, the proportion should be selected before application depending on the requirements and the type/size of mould you are pouring into).

Recommendations for working with HandiCast polymer plaster:

Proportions: remember to add HandiCast polymer gypsum to water, not the other way around. First measure the correct amount of water and then gradually add the gypsum, sticking to the proportions on the packaging. Proportions can vary depending on the particular gypsum, so it is always worth checking the label on the pack. If you are adding dry pigments, deduct the correct amount of pigment from the measured amount of gypsum and mix the dry components dry before adding the water.

Mixing: can be done either manually, using a plastic spatula, or mechanically, using a E-CUPSTONE polymer plaster mixers. Pour the water into a suitable container and then gradually add the gypsum, stirring continuously for at least 90 seconds. It is important to mix all the ingredients thoroughly until you have a uniform, smooth consistency. Make sure you mix all parts of the mixture.

Pouring the mixture: Once the gypsum mixture is uniform, pour it into a suitable mould or onto the target surface. Make sure that the mould or surface has been properly prepared beforehand.

Important information about HandiCast polymer plaster:

Colour variations in HandiCast polymer gypsum, which is produced from natural gypsum, can result from environmental factors such as temperature, humidity and the composition of the natural raw materials used in its production. These variables affect the final shade of the product. We recommend a test casting before full application.

How do I calculate the required amount of HandiCast polymer gypsum and water?

New mould? Measure its volume with water and then calculate the values to obtain the proportions of the ingredients. All values are given in grams.

X - volume measured with water, grams

G - weight of gypsum (powder), gram

W - water weight, gram

G=X*1.66

W=G/4
