لياسة خفيفة الوزن لأسطح AAC

Premix Plaster LW is a cement-based plastering 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 LW is specially designed for spray machine application and contains a special shrinkage control additive, and provides good adhesion with a uniform color surface.

الاستخدامات

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

المزايا

  • 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.

تعليمات الاستخدام

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

Add to the mixing container 6 - 8 liters of water for each 50kg bag of Premix Plaster LW. 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 300 - 500 ltr/hr for the application using a plastering machine, depending on the rubber pump’s status. Use the mixed material within 90min. 

Do not add water to the mix once the mixed mortar starts to harden.

Apply Premix Plaster LW in single or multiple layers 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 the material to a uniform thickness of 10 - 25mm. When Premix Plaster LW starts to set, smoothen the material to the desired appearance. 

For multiple layers (which is not advised due to the design criteria of lightweight structures), follow the practice mentioned in ASTM C926, 10 - 15mm/layer with rough finishes, 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, smoothen the material to achieve the desired appearance.

Cure Premix Plaster LW by spraying water on the applied materials’ surfaces 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.

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