Method of application

  • Remove dust, dirt, grease, and loose parts off the surface.
  • Rinse the surface to saturation and remove water surplus.
  • Chisel out and around external defects, embedded gravel, wires, and exposed reinforcing steel and repair prior to applying the sealer.
  • Fill and smooth wall-floor corners, using the appropriate materials 42 hours before applying BITUMSEAL.
  • Pour the contents of one bucket (5 kg) BITUMSEAL LATEX into a container of a mechanical mixer. Start mixing and add slowly, while mixing, the contents of BITUMSEAL bag (20KG). Mix thoroughly until a homogenous, easy to apply mixture is obtained. Rinse the adhesive residue in the bucket with about 1 liter of water and add to the mixture.
  • Apply the prepared mixture on the side of the wall that faces the water (positive and negative sealing), using a brush or a trowel. In the event of repaired spots, apply the mixture over the repair after it dries.
  • Apply 2 coats of 1.25 kg/m². Apply the coats, in crisscross directions.
  • It is recommended to use BITUMSEAL in two colors, to ascertain full coverage of the surface by the sealer.


About 2.5 kg/m², in 2 coats, 1 mm thick each. For sealing against water pressure over 3 meters high, apply a third coat.


About 90 minutes. It is recommended to stir every 15 minutes, to prevent crusting


BITUMSEAL -  20 Kg bag.



Clean with water, while the mixture is still wet. Clean dry mixture with acetone.
