Constrobond Pre Mix Plaster
Product Introduction
ConstroBond Pre Mix Plaster provides a solution to overcome inherited inaccuracies due to traditional method of mannual batching and mixing of plaster mortar on site. The dry mix consists of processed sand which is graded and distributed as per particle size and proportionately mixed cement and other admixtures. The application method requires mixing of water before application and the mix is ready for plastering. ConstroBond Pre Mix Plaster can be used for both external and internal plastering.
ConstroBond Pre Mix Plaster can be applied on:
- FlyAsh Blocks (Aerated Autoclaved)
- FlyAsh BrickWalls
- ClayBrick Walls (Burnt Bricks)
- StoneWalls
Pre Mix Plaster Coats
Internal
Single coats are recommended to cover the internal side of walls i.e. Finish coat of 10-15 mm, further depending upon site conditions
Availability : Packaging 40 Kg bags
External
Two coats are recommended to cover the external side of walls i.e. Base coat of 10-15 mm and Finish coat of 8-10 mm to get a total thickness of around 20-22 mm, further depending upon site conditions. After base coat, minimum 2 to 3 days curing must be done before application of finish coat.
