Cementitious scratch coat/ key coat.

Spatter Dash SB cement based key coat composed of hydraulic binders, selected sand aggregates and high performance additives. It is supplied as a dry powder in pre-weighed bags ready to use on site, which requires only addition of clean water to produce easily spray-able mortar. Spatter Dash SB is a high quality product for multipurpose applications and contains special bonding agent.

Uses

  • As an internal & external scratch coat for plasters. 
  • Use on block walls, fair-faced concrete, and precast panels before plastering application. 
  • Plaster bond enhancer and mechanical key on horizontal, vertical, and overhead application.

Advantages

  • Factory controlled pre-blend ensures consistently high quality. 
  • Requires only the addition of water on-site at the time of usage. 
  • Manual or spray machine application or by hawk & trowel techniques. 
  • Superior workability. 
  • Excellent adhesion on a variety of substrates. 
  • Internal & external applications. 
  • Suitable for humid & dry conditions. 
  • Suitable for vertical & ceiling surfaces.

Usage Instructions

The substrate should be sound, clean, free from loose material, grease, laitance, dirt curing compound, or any other substance that might impair the substrate’s quality bonding. 

Before Spatter Dash SB application, damp the entire surfaces with clean potable water. The substrate should be neutralized surface at the time of Spatter Dash SB application.

Add to the mixing container 11.5-14.0 liters of water for each 50Kg bag of Spatter Dash SB. 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. 

Blend Spatter Dash SB manually for small quantities and maintain the correct amount of powder to water. Mix for approximately 1-2 minutes until achieving a homogeneous mix.

Preferably, apply Spatter Dash SB in a single coat application to achieve the desired rough thickness of 4-6 mm. Apply mixed material using a mechanical spray or manual spatter machine or hawk & trowel technique. Cover 95-100% of surface area that will be plastered. 

Allow the installed Spatter Dash SB to remain undisturbed for at least 48 hours.

Cure Spatter Dash SB by spraying the applied material surface with water every 12hrs 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 all tools immediately after finishing with water. Clean hardened materials mechanically.
