KEIM Lotexan is a water bourne solution for Mineral Substrates, a colourless water repellant based on Siloxane designed for mineral substrates which penetrates deep into the pores of building materials due to its very small particle size creating an invisable barrier that stops water penetrating the walls of a building.
KEIM Lotexan for Mineral Substrates is best used for building exteriors such as render, stone, concrete and fibre-cement boards to provide water resistance whilst maintaining permeability.
KEIM Lotexan for Mineral Substrates must be applied to a dry surface which is free from dust and grease by a brush or ideally by flooding.
Surface and Environment
KEIM Lotexan for Mineral Substrates is best used for exterior surfaces which require a high degree of water resistance such as the rendering of a house or the exterior stone or concrete walls.

- A breathable, non-film-forming clear coating
- Complete water vapour permeability
- Elevated alkali resistance
- Weathering resistant
- Penetrates deep into the material
- Coverage between 0.2 and 0.8 per litre per m2 depending upon the nature of the substrate. On average expect 0.4 Litres per m2.

It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
