Description

Waterproof cement based render that is chemically resistant, fast curing restoration mortar for sewers and shafts.


Features and benefits:

  • A water tight, fast curing and fast setting restoration mortar for sewers and shafts.
  • Is fibre reinforced and develops a high compressive strength.
  • Can be applied below the waterline even under flowing water; as well as in drinking water environment.
  • Consumption: approx. 1.8 kg/L void as repair mortar; approx. 18kg/m²; per cm layer thickness.
  • Packaging: (C 590 025) available in 25 kg bag
  • Store the material in a dry environment. In originally sealed packages, the material can be stored for a minimum of 12 months.


Safety:

  • Wear protective gloves and goggles. Observe all governmental, state, and local safety regulations when installing the material.

Substrate

-

Manufacturer guidance

  • The surface has to be sound and solid, and free of oil and grease.
  • Contaminated substrates should be removed down to a contaminant free layer.
  • KÖSTER Sewer and Shaft Mortar is useable on all stable, hard mineral substrates.
  • Tiling must be removed. The substrate must be open pored.
  • When installing mortars substrate preparation is of vital importance.
  • Pre-wet all mineral substrates before installation.
  • The surface near pore structure must be saturated, (avoiding standing water and puddles) so that it does not absorb water from the applied mortar.

Application method

-

Manufacturer guidance

  • Mix 25 kg of KÖSTER Sewer and Shaft Mortar with 5.0 – 5.5 l water.
  • Place ¾ of the liquid into a mixing vessel of sufficient size and add the powder in portions while continually mixing with a slow rotating double paddle electrical mixer.
  • Add the remaining liquid as needed during mixing to adjust the mortar to the desired consistency.
  • Mix until a homogeneous, lump-free consistency is reached.
  • Minimum mixing time is 3 minutes.
  • The mortar has a pot life of approx. 20 minutes.
  • Apply KÖSTER Sewer and Shaft mortar using customary mason’s tools in one layer.
  • The minimum thickness for a water tight coat is 4 mm, maximum thickness is 3 cm per layer.

Performance:
