Mixing
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.
Application
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.
Curing
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.
Cleaning
Clean all tools immediately after finishing with water. Clean hardened materials mechanically.
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.
Ensure the substrate is suitable for the application of Spatter Dash SB; 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.
Spatter Dash SB is highly alkaline; therefore, avoid direct contact with eyes or skin. It is recommended to use protective gloves and goggles during application.
