A harder setting dense plaster used in the production of block and case moulds. Plaster to water ratio: 100 to 51 by weight. Mixing time approx. 2-4 minutes. The precise consistency to use will need to be adjusted to suit the individual application. Changes to plaster to water ratio will influence product performance particularly setting time and strength.
Storage: Plaster based products are not recommended for conditions where they are likely to belocated externally or in any way subjected to weathering or excessive dampness. Absorption of moisture can result in changes to physical properties, including a reduction inthe set strength of plasters and also a lengthening of setting time. Gypsum minerals can be affected by absorption of moisture and may change physicalproperties.To help protect the product during use, open or part used bags should be carefully folded and closed. This plaster should be used within 6 months of purchase.
