kAlx kP1030 - Pointing and Masonry Mortar

For pointing and masonry laying up to moderately salt-loaded substrates

Kalx kP1030 - 25 kg Bag 265px

kAlx kP-1030 Pointing and Masonry Mortar (DIN 18557) is a purely mineral product, composed of hydraulic lime and is excellently suited for pointing masonry work in non to moderately salt-loaded substrates.

Suitable for use on internal and external applications, kP-1030 is composed of natural hydraulic lime. It is highly vapour permeable, has an open and porous structure and is non-shrinking.


kP-1030 lime-based Pointing and Masonry Mortar undergoes a relatively quick carbonation and hydraulic hardening process. Both hardening processes run parallel and so result in an acceptable strength after only a few days.

Where there are high levels of salt loading we advise using the Jahn M110 Pointing Mortar.

  • Salt, frost and moisture resistant
  • Moisture regulating
  • Supplied ready to use – just add water
