RS Bitukold is a rapid setting, cold applied thixotropic bitumen emulsion designed for sealing vertical joints. The cationic formulation of RS Bitukold ensures a rapid set even in cold, damp conditions, with an initial cure taking place within 15 minutes. RS Bitukold is mainly used for the protection of new joints in freshly laid asphalt or macadam.

Where to use
  • Transverse and longitudinal vertical joints
  • Horizontal cracks in asphaltic roads
  • Trench reinstatements
  • Patch repairs
  • Drain or manhole frames
  • Kerb channels


RS Bitukold should not be applied in ambient temperatures ofless than 5°C. Ensure surface is clean and free from loosematerial, oil, grease, standing water and weeds.


RS Bitukold can be applied by pouring from a spouted watering can or, alternatively, spray applied through the Roadmaster Sprayer.


RS Bitukold should be applied at a rate of 0.7 - 1.5kg/m2 depending upon the texture and porosity of the surface andthe application method. For joints 50mm deep, a 15kg bucket covers approximately 200 linear metres. Saw cutting the edge of the joint will maximise the rate of spread.


RS Bitukold is available in re-sealable 15kg black lidded buckets(36 x 15kg per pallet) or cardboard boxes containing 60 x 10kgbags.


Protect from frost or extremes of the sealed buckets undergood storage conditions.
