For advice and further reading read our 'Using Raw Materials' PDF
Mixing ratio is 100 plaster to 68 of water, so for the 2.5kg powder in the bucket you would add 1.7Ltrs of water and that would make a shape with a dimension of 280mm x 190mm x 50mm or 2660cm3
The re-useable bucket contains a cup for a simple measurement of 3 cups of plaster to 2 cups of water.
Wear an FFP3/P3 dust mask when mixing powders.
Plaster contains <1% crystalline silica which if inhaled will cause long term lung damage, therefore we recommend the wearing of a FFP3/P3 Mask. Keep working areas free of dust cleaning up with a damp sponge.
In keeping with our overall general advice, we also suggest wearing full PPE mask, safety glasses, gloves in a ventilated area.
It is a sensible precaution for children not to work with raw materials.

Pleased with product, packaging and delivery
I found it perfect for making a damp box. Very easy to work with and quick delivery
Works well, just be mindful that as soon as it's mixed it starts to cure, toward the end of my experiment I had to rush to use it, my own fault for working too slowly
Good quality easy to use
Nice smooth plaster,
