Builders, home improvers, and designers add render to facades for several reasons;   to protect the structure, improve the aesthetics, and to boost energy efficiency. But if the products aren’t used effectively, or applied incorrectly, they can cause lasting problems that they were designed to overcome, such as water ingress, trapping moisture, which can lead to cracking or damp.

KEIM Mineral Paints Limited are known for their natural, environmentally friendly interior and exterior paints, but here we focus on their lesser-known range of renders; each designed for specific applications but all providing lasting durability, protection, and performance.

Why do we render?

There are several reasons why we would choose to apply render. The common reasons include;

  • Protection from the weather – water soaking, reduce damp, in wet climates
  • Improve structural durability – cover cracks, stabilise aging masonry
  • Aesthetic upgrade – modernise older properties, add colour or texture
  • Improve insulation – keep heat in during winter, lower heating bills

How KEIM is different

Typical render types available include cement, lime, acrylic, and silicone based. KEIM renders, as with all KEIM products, use natural, inorganic ingredients, reflecting the philosophy that dates to 1878, of being kind to use and kind to the environment.

Advantages of KEIM mineral renders;

  • Environmentally friendly ISO 14001
  • High vapour permeability (walls can breathe)
  • Provides durable, colour stable protection
  • Fire resistant to A1
  • UV stable
  • Increases light reflectivity
  • Available in bagged powder form

Products include

  • KEIM Uniputz 1.3 (KEIM Universal Render), multi-purpose, pre bagged mineral render, versatile, easy to apply. Extremely flexible to accommodate high degree of movement such as thermal expansion, whilst preventing the surface from crazing or cracking
  • KEIM Uniputz 0.6 version (KEIM Universal Render Fine). A ready to use product ideal for interior or exterior application using hydraulic lime, white cement with sand and mineral fibre fillers
  • KEIM NHL-KP 3.0 (KEIM Kalkputz Grob), perfect for localised patch repairs of existing lime rendered facades and lime base coat for KEIM NHL-KP 0.6
  • KEIM NHL-KP 0.6 (KEIM Kalkputz Fine), a complete thin lime coat system to be subsequently painted

Where can they be used?

  • Concealing cracks, flaking, or differences in textures
  • Ideal for renovation, historic monuments, listed buildings (KEIM Uniputz 1.3)
  • Can also be applied onto existing sound render
  • Used as a total render or for patch repairs

KEIM – sustainable products to repair and protect concrete

Concrete … a building material of choice for many due to its structural strength, cost effectiveness, and rugged good looks; often chosen to help control heating and cooling of a building to incorporate efficiency and sustainability into the design. But it can have its limitations. What happens when that once fresh finish starts to degrade, weather or requires repair? How do you ensure the surface and substrate last for years if not decades to come?

Here’s where KEIM can help. Known for their mineral eco-friendly paints for interior and exterior decoration, they also have a range of products specifically designed for concrete.

Whether you’re working on a new project, undertaking a repair, or simply looking to protect the surface from decay, KEIM has a product to suit.

What are the common problems that affect concrete?

There are three key concerns connected with concrete;

  • Carbonation – this occurs when the surface begins to decay. It’s caused by carbon dioxide, sulphates from vehicle exhaust fumes, or chlorides from de-icing salts. Carbonation can affect the structural strength of the substrate. Not great if the structure is a bridge!
  • Repairs – remedial repairs are commonplace but can be problematical and lead to a patchwork effect, or colour variants.
  • Protection – against the ingress of water or driving rain, which can lead to structural damage.

How can KEIM help?

In short, their products help unify the look of the concrete (overcoming colour variants or imperfections) while offering a long lasting, breathable protection.

What products do they have?

Products for cleaning, reinstatement, and repair as well as protection. They also have a concrete wash for those that want to experiment with design or colour!

Concretal W – Water repellent for protection against weathering and water. Lightfast, matt surface, antistatic, non-flammable.

Concretal C – Waterproof protection against carbonation and chlorides.

Concretal Lasur – Acts as a stain to equalise colour variations while maintaining the structure and appearance of concrete.

Concretal – Black. Provides a matt black, ultra chic finish in five shades to add drama and visual impact.

Where have KEIM been used?

You name it! From bridges (Sheffield Parkway supertram) to tunnels (London Underground), leisure sites (Dudley Zoo, Olympic Park) to prisons (HMP Five Wells), from retail (John Lewis) to education (Bristol University); the products are ideal for any concrete project.

KEIM unifies uneven or variable finishes and offers protection.

What are the key benefits of KEIM’s concrete range;

  • Easy to apply
  • Long last protection
  • Fire resistant to A2-s1, d0
  • Ideal for interior or exterior use
  • Cradle to Cradle Certification
  • Evens out imperfections
  • Maintains breathability of the substrate

KEIM – Protection and transformation of through coloured render.

Rendering the exterior of a building is typically used to enhance its appearance and provide protection from weathering and rainwater.  Whilst silicone or acrylic ‘through-coloured’ render finishes may seem an economical choice, there can be subsequent problems which can quickly spoil the aesthetics of the building.

Marketed as a long-term render that is structurally sound, there are common issues that can arise which include difficulty when repairing, with repairs to damaged areas resulting in colour and texture differences, which leaves a patchwork effect.

Through coloured renders typically contain petrochemical ingredients, they look fresh when first applied, but over time the components within the render provide an organic food source for contaminants such as algae, which can significantly build up on the render surface.   Petrochemical based pigments within through coloured render are prone to fading under UV light.

KEIM, who have specialised in environmentally, eco-conscious paints since 1878, offer products that can refresh and repair these renders, to provide a protective, breathable, fade free finish which is far more resistant to the build up of algae and mould.

KEIM Soldalit-ME provides the perfect refurbishment and repair solution.

KEIM-Soldalit-ME is a highly specialised sol-silicate exterior mineral paint with photocatalytic qualities, not only is KEIM-Soldalit-ME breathable, fade free and environmentally friendly, it also actively reduces harmful gases and organic pollutants in the atmosphere.

Vanessa Fox, Commercial Manager helps to explain; ‘KEIM have been approached to assist with numerous projects where issues have arisen on through colour render, where façades have faded, where repairs are difficult to carry out, and in particular where significant issues with algae build up have occurred.’

‘By redecorating these buildings using the KEIM-Soldalit-ME system, not only can we transform the look of the façade, we protect the underlying render from the effects of UV light and we offer a surface that restricts the build-up of algae. Our paint helps to clean the air as well as offering fire resistance with a fire classification A2-s1, d0 ideal for use on all manner of projects from heritage to high-rise.’

Vanessa continues, ‘All of our products are designed to be kind to use, and kind to the environment. Our products have been in use for decades and all with proven eco credentials, they are Cradle to Cradle Certified®, and will help protect the building’s exterior from ingress of rainwater to remain fresh and vibrant for years to come.’

Paint partnership for latest office-to -flats conversion

Fairfax House, located in the Arena Quarter of inner-city Leeds is the latest building to undergo a complete renovation, converting a no-longer needed office space into residential accommodation. The 1960’s, seven storey office block, will be transformed into 154 studio and one-bedroomed apartments, with an additional two- storey extension.

Recent fire safety and building regulations insist that relevant buildings above 11m require that only non combustible materials are used on their exterior. It’s no surprise therefore that KEIM Mineral Paints, which conform to these most stringent standards, were specified by Colbre Projects to be used as the exterior paint on Fairfax House.

Paul Milligan, Business Development Manager at KEIM UK helps to explain, ‘We have been involved with various housing associations and councils as awareness of our fire resistant paint becomes more prominent. Our KEIM Soldalit exterior paint meets the A2-s1,d0 fire resistance standard, and this is just one of the properties which make our products ideal for residential buildings and wholly unique. Not only are all of our products made from natural mineral ingredients, they are also breathable, non-toxic, low VOC, and most relevant for Fairfax House, fire resistant.’

It made sense for KEIM to work with a specialist architectural spray-painting company, ORS Limited, that had the knowledge and capabilities needed for such a tall and prestigious project.

Jo Thornicroft, Sales Director at ORS Limited explains, ‘We have completed over 400 site rollouts for customers including Habitat, BMW, and Next providing retail shop fronts, cladding and curtain walling. The Fairfax House project utilises our vast architectural spray-painting experience. This application technique ensures that the KEIM Soldalit is applied evenly, and effectively. Imagine painting a seven-storey building! This method is far more time efficient, and therefore better for the building, and the client, to reduce application time and minimise disturbance.’

The project which started in April 2023, is due for completion at the end of this year and uses the combined skills of Leeds based buy to let property company YPP, and Brewster Bye Architects.
