SURFACE PREPARATION – NEW SURFACES 

Cement Plaster (non-friable), Gypsum Plaster (non-friable), Composite Boarding and Fibre Cement

  • Fresh cement plaster should be allowed 21-28 to dry and cure. 
  • For very absorbent surfaces such as gypsum plaster more than one coat Sparcolux Solvent based Plaster Primer may be required to achieve correct binding and sealing.

 

Concrete

  • Remove any uncured cement, grease, and mould-release agents by high-pressure water blast, or wash with a strong sugar soap/water solution. 
  • Rinse off thoroughly with clean water and allow drying. 

 

PREVIOUSLY PAINTED SURFACES 

Old Paint in Poor Condition 

    • Completely remove all loose and flaking paint.  
    • Remove oil, grease dirt or any other contaminants with Sugar Soap and water.
    • Allow  to dry. 
    • Loose, friable  surfaces should be removed and repaired.
    • Chalky, efflorescent surfaces should be thoroughly brushed or prepared with high pressure water cleaning. Note, that heavily chalked or thickly layered areas may require Sparcolux Bonding Liquid. 
    • Prime all exposed areas. For very absorbent surfaces more than one coat Sparcolux Solvent based Plaster Primer could be required to achieve correct binding and sealing. 
    • Mould, lichen, etc – need to be completely removed before priming the substrate.
