Mixing ratio is 100 plaster to 70 of water, so for the 2.5kg powder in the bucket you would add 1.75Ltrs of water. This will 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.
