Product Description

Keim Lotexan N is a siloxane based water repellent impregnation to reduce the water absorption of natural stone. Also used as a dust suppressant.

Keim Lotexan N penetrates into the pores of the natural stone. Once the solvent has evaporated, the active ingredient is deposited on the walls of the pores and develops its water repellency by reacting chemically with the moisture normally present in the stone and the atmosphere.

Best Uses

Keim Lotexan N is suitable as a water repellent protective treatment, in particular for uncoated, porous natural stone. It can be used to protect all common kinds of natural stone, whether alkaline or neutral, from water, acid rain and atmospheric pollution. This treatment does not seal the pores in the natural stone, ensuring that its water vapour permeability remains practically unchanged.

  • Easy to apply
  • Water vapour permeable
  • Totally clear
  • Surfaces shows no sign of treatment

Application

All gaps, cracks and holes in the substrate must be filled prior to any further treatment. Any suspect mortar jointing should be raked out and re-instated where necessary. Any newly repaired areas must be allowed to dry out for a minimum period of 15 days prior to the application of Keim Lotexan N. All surfaces should be washed down with clean cold water to remove all surface dirt and dust.

Keim Lotexan N should be applied by low pressure spray or brush, working from the bottom of the substrate upwards, firstly in a horizontal manner. After a period of approximately 10 minutes a further application may be applied, again from bottom to top, this time in a vertical manner, thus ensuring that all facets of the substrate are well coated. It is important that Keim Lotexan N is applied onto a dry surface and during a period of time of at least 2 hours when no rain is expected. To prevent the possibility of water ingress through adjoining walls, which would migrate through to the offending areas, contractors should apply Keim Lotexan N products in the manner mentioned above onto any flank or adjoining walls for a depth of at least 1 metre down these walls, even though these areas may not be exhibiting water
ingress internally.

A minimum depth of penetration of 2mm is usually necessary in order to achieve effective water repellency.
