Beeck Mineral Paints

Highly durable and protective coatings which bond with the substrate – particularly suited to masonry, stone, lime render and concrete.

What is a Mineral Paint?

A mineral paint is a masonry coating that creates a bond with the underlying mineral substrate. This is different to conventional oil based paints and masonry paints, because rather simply forming a surface film coating, Mineral paint becomes an integral part of the substrate through creating this bond.

The bond between the paint and substrate is a chemical bond, rather than a psychical bond, and is called Silicification. Silicification is a chemical reaction between mineral surface, filer and the potash water glass and thus no surface film is being produced. Instead, a silicified, micro-porous unity of surface and coating is created.

What are the reasons to use Mineral Paint over standard masonry paint?

  • Extremely long lasting and durable finish
  • Weather resistant
  • Highly durable connection between paint coat and substrate.
  • Exceptionally resistant to UV light.
  • Paint colour and coats can last for decades
  • Resistant to algae, fungi and microorganisms
  • Acid rain resistance
  • Breathable, porous structure
  • Not prone to static charging and thermo-plasticity
  • Fewer dirt particles cling to the surface, can be washed easily.
  • Free of organic additives or solvents.
  • Reduces carbonation of cement-based materials.

What does a Mineral Paint do? (Technical Properties)

One of the key aspects of Mineral Paint is that, unlike traditional masonry paint, the coating allows free passage of water vapour through it. The vapour permeable qualities mean that Mineral Paints are especially ‘breathable’.

Due to the coating being bonded to the substrate, and the breathable nature of the coating, this means that water and moisture won’t get trapped between the wall and the Paint. Ultimately, Mineral Paints are as breathable as a lime wash but behaves more like masonry paint. This bonded coating maintains wall dryness and prevents structural damage.

The bonding is also highly durable that goes above and beyond that of a standard masonry paint or lime wash. This is due to the weathering and UV resistant properties. The chemical fusion with the substrate and the UV stability of the binder are the fundamental reasons for the extraordinarily high lifetime of silicate paints.

Additionally the lack of surface moisture on the coating, created by the permeability, reduces the risk of infestation by algae and fungi. This is further aided by the high alkalinity of the binding agent which adds to the inhibitive effect against microorganisms.

Furthermore, as mineral paint coats are not prone to static charging or thermo-plasticity this means that fewer dirt particles cling to the surface and don’t build up as quickly. Also due to these properties, dirt can also be washed off Mineral Paints far easier than standard masonry coatings.

What surfaces is it suitable for?

  • Concrete
  • Earthen Plaster
  • Lime Plaster and Lime Sandstone
  • Masonry
  • Stone

What surfaces is it not suitable for?

  • Wood
  • Metal
  • Plastics

What are its best uses?

  • Exterior Substrates
  • Historical buildings or constructions
  • Sustainable construction
  • Substrates exposed to high UV radiation
  • Substrates exposed to extreme weather
  • Constructions areas prone to algae and fungi infestation

Are there any environmental considerations?

Due to the sustainable sourcing of materials and production of Mineral paint, they are more eco-friendly than most competitive masonry paints. They are also free of solvents, VOC’s, and are carbon neutral.

Furthermore, mineral paints are flame retardant and do not give off any toxic gasses if burnt.

How long will Mineral Paint last?

Due to the permanent bond of the mineral paint to the substrate, Mineral Paints create an extraordinarily durable finish. This is due to the paint becoming an integral part of the substrate.

Which type of Mineral Paint should I use?

Single-Component silicate paint: The more common use mineral paint for use on both interior and exterior substrates. Can be used by both homeowners and trained professionals.

How do you apply Mineral Paint?

Check substrate suitability as required and we highly recommend trying out a test area before application to entire area.

Recoatable at the earliest after 12 hours. Protect fresh coating from rain i.e. by using scaffold tarpaulin. Do not use in wet, frosty, or excessively warm weather conditions.

Application is possible with roller, brush or using an airless spraying method. Apply to self contained areas with an absolutely thin coating, with no overlapping and uniformly in one continuous pass as a cross coat.

Upon application, avoid roller edges, ridges, overlapping and over coating coats that have already begun to dry.

What are the Colour Selection Options for Mineral Paints?

The mineral paints that we recommend, and can supply, are manufactured by BEECK and include a range of their mineral based products for exteriors’.

Available in more than 300 absolutely non-fading mineral colour tones as produced in the BEECK colour range.

However, Holman Specialist Paints will also be able to tint your exterior paints to match your exact specification from any other colour chart or sample.

Due to the UV resistance of Mineral paint, the colours do not fade and there shouldn’t be a discernible difference between buildings painted in the same colour at different times.
