SnowCast ready-mix for gypsum casting in Lastryko and Marble.


Snow-white colour.
Just add water.
A one-component polymeric gypsum consisting of high-strength gypsum, mineral fillers and modifying additives. According to its characteristics, it is practically no different from a two-component, acrylic resin-based gypsum. At the same time, it looks more natural.
Attention - the product needs to be protected from water absorption (impregnate or lacquer).
It is an odourless material that contains no solvents.
All that is needed to make the mixture is a scale, a mixer and mixing containers and water.
The material is completely non-flammable.
Suitable for the production of figures, models, sculptures, decorations, prototypes, architectural elements, replicas, ceiling and wall panels, scenographic elements

Synonyms: Cast stone, liquid stone

Properties:

  • Fast curing time (up to 40 minutes)
  • Excellent fluidity
  • Smooth casting surface
  • Perfectly reproduces fine elements
  • Thanks to the modifying additives, it is low in water absorption
  • Stains well with different types of dyes
  • UV resistant
  • Non-flammable
  • Ideal for creating Lastryko and Marble products
  • Does not stick to dishes

The mixture consists of high-strength gypsum, mineral fillers and modifying additives. The binder is natural gypsum.
It is a uniformly mixed, ready-to-use, dry mixture of snow-white colour. Due to its predominantly gypsum composition, it contains no harmful substances. Allows ideal casting without a vibrating table.


FEATURES:

  1. Optimises process time (mix life, curing time) for artificial stone production.
  2. Eliminates the need to purchase chemical additives.
  3. Eliminates the problem of instability in the properties of individual elements.
  4. Saves the contractor from the problems of dosing ingredients, including very small quantities.
  5. It speeds up work by eliminating ancillary operations.

Mixing ratio:


LASTRYKO polymer gypsum is prepared by mixing the powder with water in a ratio of:
100:22 (100 grams of powder and 22 grams of water).
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.
The correct proportions are key to achieving optimum mix properties - the less water, the harder the product.
Use a scale to measure the ingredients!

APPLICATION:


Recommendations for the work:

  • mix the material according to the principle "mix to water, not the other way round"
  • Stir with an agitator or drill/driver for at least 90 seconds until a homogeneous mass is obtained
  • Pour the resulting mixture into the mould


PARAMETERS:


Setting time: 25-40 minutes (depending on environmental temperature)
REMEMBER the bonding time.
As soon as the gypsum is poured into the water, it starts to cross-link and you have 10-15 minutes (at room temperature) before the mixture is pre-cured (you can extend this time with a supplements).
Plan the amount of gypsum to be mixed so that you have time to mix it, apply it and wash the mixing tools and container.

  • Colour: snow white
  • Mixture density: 2.14kg /dm3
  • Running time: 10-15 minutes
  • De-formation time: approx. 40 min
  • Compressive strength after 72g: 45 MPa

Specific gravity: 1000 ml - 2135 gr (1750 gr gypsum + 385 gr water)

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


New mould? Measure its volume with water and then calculate the values for obtaining 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*1.75
W=G*0.22
Example 1:
I have 180 gr of water in the mould:
Weight of gypsum (powder): 180*1.75 = 315 grams
Weight of water: 315 *0.22 = 69 grams

Inorganic pigments based on iron oxides are suitable for colouring the mixture, pigments can be found in our other auctions (dosage 0.1-8 % in relation to dry mass).
Colour combination:

  • red + yellow = orange
  • red + blue = violet
  • blue + yellow = green
  • blue + yellow + red = black
  • black + orange = brown
  • blue + red + green+ white = heather
  • yellow + orange + red + blue = salmon
  • yellow + black = olive
  • red + blue + green = amaranth
  • orange + yellow + white + green = cream

Choose the proportions yourself by trial and error to achieve the right shade.
For the Marble technique, dedicated pigments in liquid form.

HEALTH AND SAFETY:

The product can be handled without risk, provided the appropriate precautions as for chemicals are observed. Keep uncured materials away from foodstuffs and children. Protective clothing, latex or vinyl gloves and safety goggles should be worn to protect against splashing. The processing room should have efficient ventilation. Hands should be washed thoroughly with soap in warm water after each operation and dried with a disposable paper towel after washing.
