  • Suitable for use on unpainted surfaces.
  • For use on alkaline mineral substrates such as concrete, render, brickwork and natural stone.

Description

A siloxane-based, clear, dust suppressant and water repellent treatment.

Keim Lotexan N was developed as a dedicated generic variant for mineral substrates with a lower alkalinity, such as weathered natural stone.

  • Acts as a water repellent and dust suppresser.
  • Longevity.

  • Highly water repellent.


Surface preparation:

  • Any algae growth should be wire brushed to remove all growths and treated with Keim Algicid, brush applied, undiluted and allowed to remain undisturbed for three hours before thoroughly washing off. All gaps, cracks and holes in the substrate must be filled prior to any treatment.
  • Any suspect mortar jointing should be raked out and re-instated where necessary.
  • Any new/ repaired surfaces should be left for a minimum of 15 days prior to any treatment taking place.

Product Reference

Lotexan

For concrete, render, brick and other alkaline substrates.


Apply the first coat of Keim Lotexan by low-pressure spray, working from the bottom of the substrate upwards, firstly in a horizontal manner. After a period of approximately 10 minutes, a further coat should be applied again from bottom to top in a vertical manner, thus ensuring that all facets of the substrate are well coated. It is important that Keim Lotexan is only applied to a dry surface and care is taken to avoid runs, as the material is thin.

Lotexan N

For weathered stone and substrates with lower alkalinity.


Keim Lotexan-N is optimized for application onto pH neutral surfaces. Apply the first coat of Keim Lotexan-N by low-pressure spray, working from the bottom of the substrate upwards, firstly in a horizontal manner. After a period of approximately 10 minutes, a further coat should 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 only applied to a dry surface and care is taken to avoid runs, as the material is thin.

Coverage

0.2—0.4 L/m².

For two coats on a smooth surface.
