Sprayable light weight premixed plaster
Plaster Cement Perlite is composed of hydraulic cement, Perlite, and selected aggregates with special additives. It is supplied as a dry powder in pre-weighed bags ready to use on-site, which requires only the addition of clean water to produce a cohesive mix. Plaster Cement Perlite is a high-quality product and provides as underlayment on various facets of the projects.
- Factory controlled pre-blend ensures consistently high quality.
- Requires only the addition of water on-site at the time of usage.
- Lightweight.
- Assist the thermal insulation systems in thermal insulation.
- 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.
- BSEN 998 -1 type LW
- ASTM C926
- Cement type: ASTM C150, type1
Plaster Cement Perlite is supplied in 25Kg Bag. Consumption - 1 to 1.2 kg/m2/mm.
Stated consumption data are for general guidance. The actual value depends on the nature of the substrate, method of application & wastages.
An original sealed bag of Plaster Cement Perlite has a shelf life of 12 months provided it is stored clear of ground in a dry shaded place, at temperatures between 5ºC - 35ºC.
Design Criteria
Plaster Cement Perlite is designed to be used at thicknesses between 10 -20mm in a layered application. The product can be applied on block walls without using a scratch coat as long as the substrate is properly neutralized before application. In cases of fair-faced concrete, a scratch coat is needed to ensure mechanical keying and enhanced bonding.
Mixing
Add to the mixing container 7-8 liters of water for each 25 Kg bag of Plaster Cement Perlite. 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 a uniform, lump-free consistency is achieved.
Do not add water to the mix once the mixed mortar starts to harden.
Smooth Concrete Surfaces
Apply Spatter Dash SB before the application of Plaster Cement Perlite.
Application
Plaster Cement Perlite can be applied in single or multiple layers on rough surfaces. On smooth surfaces, it should be applied after the application of a spatter-dash coat.
Rod or level to a uniform thickness immediately then follow smoothing the material to the desired appearance.
For multiple layers, allow the plaster to partially dry (60-120 minutes depending on the weather. Apply the second coat at thickness as described above to the desired appearance or follow the ASTM C926 procedures for better layer application results regardless of the weather conditions.
After the surface appears stiff but still moist, follow the smoothing the material to achieve the desired appearance.
Curing
Plaster Cement Perlite is best cured by spraying water on its surface every 8-12 hrs for a minimum of 3 days. During hot & dry conditions, allow curing for a minimum of 5 days. It will help to obtain high mechanical strengths and minimize the risk of surface cracks.
The substrate should be sound, clean, free from loose material, grease, laitance, dirt curing compound, or any other substance that might impair the quality of bond with the substrate.
Before the Plaster Cement Perlite application, damp the entire surfaces with clean potable water. The substrate should be a neutralized surface at the time of the Plaster Cement Perlite application.
- Ensure the substrate is suitable for Plaster Cement Perlite; in case of doubt, try on the sample area to assess its suitability.
- Do not apply the product under direct rain, extreme wind, and temperatures below +5ºC or above +45ºC.
- Clean tools with water before the mortar hardens. After the hardening, its residuals can be removed mechanically.
Plaster Cement Perlite is highly alkaline; therefore, avoid direct contact with eyes or skin. It is recommended to use protective gloves and goggles during application. Any skin contact should be washed with soap and water. In case of eye irritation, immediately wash with a copious amount of clean cold water. Seek medical advice.
Plaster Cement Perlite is non-flammable.
