Premix Plaster S

Sprayable cementitious premixed plastering/rendering material.

Premix Plaster S is a cement-based plastering/rendering material composed of hydraulic binders, selected manufactured sand, aggregates, and special additives. It is supplied as a dry powder in bags/bulk ready to use on-site, which requires only the addition of clean water to produce cohesive mortar. Premix Plaster S is specially designed for application by spray machine. It can be used manually if required, contains a special shrinkage control additive, and provides good adhesion with a uniform color surface.

Uses

  • Designed for spray applications, internally or externally, in wet & dry conditions, onto block walls & rough surfaces, without the necessity of the prior application of a spatter dash coat’s prior application.

Advantages

  • Fast mixing application using a spray machine.
  • It contains a special additive that reduces friction and prolongs the lifespan of the equipment.
  • Factory controlled pre-blend ensures consistently high quality.
  • Requires only the addition of water on-site at the time of usage.
  • Uniform color/mass. u Improved workability & curing.
  • Easy application with uniform work flow enables high productivity & superior finishing.
  • Strong adhesion on a variety of substrates.
  • Internal & external applications.
  • Shrinkage control reduces surface cracks.
  • Suitable for humid & dry conditions.

Usage Instructions

The substrate should be sound, clean, free from loose material, grease, laitance, dirt curing compound, etc. Before Premix Plaster S application, damp the entire surfaces with clean potable water, and the substrate should be neutralized surface at the time of the Premix Plaster S application.

Add to the mixing container 6 - 8 liters of water for each 50Kg bag of Premix Plaster S. Add the powder to the water and mix with a mechanical plaster mixer or low-speed electric drill fitted with a suitable paddle for 3-4 minutes until achieving a uniform, lump-free consistency. 

The recommended water flow rate is 350 - 550 Ltr/ hr for the applications that use a plastering machine, depending on the rubber pump’s status. Use the mixed material within 90 min. Do not add water to the mix once the mixed mortar starts to harden.

Apply Spatter Dash SB prior to the application of Premix Plaster S.

Apply Premix Plaster S on rough or smooth surfaces using a spray machine at a thickness of 10 - 25mm per layer. Apply a Spatter Dash coat on smooth surfaces. 

Rod or level to a uniform thickness. 

When the plaster starts to set, level the material to the desired appearance using suitable plastering trowels. 

For multiple layers, follow the practice in ASTM C926, 10 - 15 mm/layer with a rough finish, a cure for two days /layer before applying the second one. Finish the final layer as desired. 

After the surface appears stiff but still moist, finish the material surface to achieve the desired appearance.

Cure Premix Plaster S by spraying water on the surfaces of applied materials every 8-12 hrs for a minimum.

Clean tools with water before the mortar hardens. After the hardening, remove the residuals mechanically.
