APPLICATION INSTRUCTIONS

  • Apply with a brush at a coverage rate of 1 kg/m² minimum to 2 kg/m².
  • Coverage rates can vary depending on surface porosity and texture.  

  • When the surface is damp Cromar Acrypol + should first be worked into the surface with the brush in a circular motion to remove excess moisture and ensure total adhesion prior to brushing out fully.  
  • Cromar Acrypol + will fill and bridge cracks up to 10 mm wide.
  • All voids should be filled with an appropriate flexible filler and allowed to set or dry.
  • Alternatively, the void may be covered with a heavy duty adhesive tape and then over‐coated with a liberal 15 cm wide brush stroke of Cromar Acrypol +.
  • Whilst the coating is wet a strip of 15 cm wide Acrypol + Scrim should be bedded into the coating and allowed to settle overnight prior to the next stage.   
  • Special attention should be given to the preparation of aluminium, zinc, galvanised or corroded metal.
