MS 30 Sulphate-resistant Sealing Slurry

MS 30

BOTAMENT® MS 30 is a mineral sealing slurry for the waterproofing of solid elements in interior and exterior areas.

The product is particularly suited for restoring old buildings and for structural elements which are in contact with sulphate-containing water.

  • Easy to handle
  • Bonds without priming on slightly damp substrates
  • High frost and aging resistance
  • Also applicable under negative water pressure
  • High sulphate resistance
  • Open to vapour diffusion

Application areas

Waterproofing of:

  • basement walls
  • floor slabs
  • splash water zones of base walls
  • moist rooms

Suitable substrates

  • concrete (strenght class ≥ C 12/15 in accordance with EN 206)
  • joint full brickwork
  • lime cement plasters and cement plasters of the mortar categories CS II, CS III and CS IV in accordance with EN 998, compressive strength ≥ 2.5 N/mm²)

Substrate preparation

The substrate must be in the following condition:

  • slightly damp, clean and frost-free
  • stable
  • free from grease, paint, cement laitance, separating agents, sinter layers and loose particles

Please also note:

  • pre-wet dry and absorbent substrates (avoid standing moisture)
  • on smooth substrates apply a spray scattering consisting of 1 part cement, 2 parts of sand and mixing water first


cool and dry at least 6 months in its original sealed container
