UniworldTM Unicoat Plaster
Uniworld Unicoat plaster is a pre-mixed single application plaster made from calcium sulphate hemihydrate to which additives are added to improve workability. UniworldTM unicoat plaster is classified as non-combustible and can contribute significantly to the fire resistance of a building. Apart from providing a smooth and high quality finish to internal walls and ceilings, Plaster Of Paris attains early strength, requires no water curing and is free from shrinkage and cracks. The Plaster Of Paris caters to all normal background like bricks, blocks and concrete. It is better than traditional plaster as it eliminates the two processes of sand cement plaster & P.O.P (Plaster of Paris) punning. Ceramic tiles can also be fixed by applying a very firm adhesive to a thoroughly dried plastered surface.
Salient features of UniworldTM plaster P.O.P. are listed below:
- Direct application on cemented surface or surface to be painted.
- Calcination process at appropriate temperature leads to shrinkage and crackfree surface.
- Finely grounded powder covers wider area and requires lesser material.
- Suitable setting time allows mason enough time for application that reduce wastage of material. Whiteness of plaster allows desired colour of paints on walls as shown in shade cards.
- Available in 20kg and 25kg semitransparent bags.
