Lasur Finishes & Colourwashes
Keim Mineral Paints Ltd
KEIM Lasur finishes are translucent colourwashes which have been developed for application onto mineral surfaces. KEIM Lasurs are used to produce finishes that create a decorative, unifying effect but retain the look and feel of a natural surface and most importantly do not appear painted. Like all mineral paints, KEIM Lasurs have a potassium silicate binder which penetrates into the mineral surface and chemically bonds to it. One of the features of this potassium binder is that it is itself protective and therefore the proportion of this clear binder can be increased, almost without limitation, to create a colourwash whilst at the same time providing the same long term performance and surface protection expected with a mineral paint coating.
Lime Render & Why Buildings Need to Breathe
Keim Mineral Paints Ltd
It is important that materials used for repair and redecoration are suitable for use on older, traditional buildings. Hard cement renders and many masonry paints do not allow the moisture that is continually being absorbed into the building to evaporate easily. This can result in damp, cold walls, condensation, flaking paint, rotten joints and other timber fittings, increased heating bills and dampness on the internal walls.
Keim Lotexan Technical Data Sheet
Keim Mineral Paints Ltd
KEIM Lotexan is a siloxane based water repellent impregnation to reduce the water absorption of natural stone. Also used as a dust suppressant. KEIM Lotexan is suitable as a water repellent protective treatment, for mineral renders, fair-faced concrete, prefabricated concrete elements, exposed aggregate concrete, calcareous sandstone and fibre-cement boards. KEIM Lotexan provides protection from water, acid rain and
atmospheric pollution. KEIM Lotexan penetrates into the pores of mineral building materials. Once the solvent has evaporated, the active ingredient coats the walls of the pores and develops its water repellency by reacting chemically with the moisture normally present in the substrate and the atmosphere. This treatment does not seal the pores in mineral
building materials.
Technical Digest - Breathability & Mositure Vapour Permeability
Keim Mineral Paints Ltd
When the term breathability is referred to with reference to building materials it is not concerned with air, but with water in both liquid and gas form. Breathability tends to be used to describe the passage of water vapour and there are a variety of related terms that are used to quantify breathability.
Water affects everything in building from the health or decay of building fabric, through to the thermal performance of the building and to the health of occupants. Particularly as we try to increase the air-tightness, thermal performance and indoor air quality of our buildings, breathability has become a critical issue, affecting all areas both of new build and of renovation
Listed & Historic Buildings
Keim Mineral Paints Ltd
Listed buildings have special architectural or historic interest and are recorded in statutory list. English Heritage are responsible for the administration of the listing system in England, CADW in Wales, Historic Scotland and the Northern Ireland Environment Agency. Conventional acrylic paints merely coat the surface and create a film around the substrate. This film forming coating does not allow moisture vapour to breathe through it, which can result in the formation of blisters which may lead to cracking and flaking paint finishes. If moisture vapour is unable to pass through the surface, this can lead to elevated moisture levels within the substrate eventually leading to friability and damage.
Technical Digest - Breathability & Mositure Movement (Staining)
Keim Mineral Paints Ltd
Keim Mineral Paint systems are highly breathable and allow free passage of moisture vapour through the substrate and paint coating. Where buildings have previously been decorated using unsuitable, acrylic based coatings which do not allow moisture vapour movement, it is likely that there will have been a build up of moisture within the substrate, resulting in high levels of saturation and/or blistering and flaking paint coatings.

Technical Digest - BREEAM Certification & Keim Mineral Paints
Keim Mineral Paints Ltd
BREEAM (Building Research Establishment Environmental Assessment Methodology), first published by the Building Research Establishment (BRE) in 1990, is the world's longest established method of assessing, rating, and certifying the sustainability of buildings.
The BREEAM rating is not directly applicable to Keim Mineral Paints and treatment products as they are less than 150microns in thickness which, when applied to substrates, will not significantly affect the environmental rating of the building.
All Keim Mineral Paints have VOC contents below 140gms/l, and are therefore, on this basis, BREEAM compatible.
Technical Digest - Cleanliness & Durability
Keim Mineral Paints Ltd
Once a surface has been painted, the type of paint material which has been used can contribute to keeping the surfaces looking clean and bright, or result in a premature build-up of dirt and dust, resulting in frequent cleaning and redecorating.
The tendency of coated surfaces to become soiled is influenced, apart from by condensation behaviour, by the static charging characteristics and thermoplastic properties of the binder. The organic synthetic resin/silicone resin binders in conventional acrylic film forming masonry paints become electrostatically charged in the wind due to friction and actually attract dirt particles onto themselves from the air. Paints with a water glass binder, such as Keim Mineral Paints are antistatic and non-thermoplastic.

Photocatalytic Difference - Keim Soldalit-ME & Keim Ecosil-ME
Keim Mineral Paints Ltd
In terms of the paint industry, the effects on air pollution should be considered from the manufacture of the materials i.e. the impact of the production process itself, through to the resultant affects of material application i.e. the release of VOCs (Volatile Organic Compounds). In the presence of Nitrogen Oxides, it is VOC s which, in addition to being respiratory irritants and strong smelling, result in the formation of harmful ground level ozone. The photocatalytic reaction converts Nitrogen Oxides and other harmful pollutants into harmless nitrates. The reaction helps to breakdown organic material and contamination's, keeping surfaces cleaner. Photocatalytic mineral paints use light energy to neutralise pollution.

Technical Digest - Algae & Fungal Resistance of Mineral Paints
Keim Mineral Paints Ltd
Algal and mould growth, including fungi and lichens, are an increasing problem in the UK on both the outside and inside of buildings, particularly on painted surfaces. For some buildings and areas the problem can be prolific, often due to a combination of environmental conditions and type of paint coatings. This is both aesthetically unappealing as well as potentially harmful, particularly indoors. There is much research and many opinions about the causes of, and treatments for, such issues, and the following is the opinion of Keim Mineral Paints.
