SMET advertises Breathable Fine Finishing Plaster in Northern Builder

Joris Smet, Director of Smet Building Product Ltd tells how choosing the right internal plaster can help improve indoor comfort in new buildings.

“The unique properties of CASEA Klimafeinputz KFP, with the ability to regulate and absorb moisture allows the substrate to breathe, protects against micro-organism growth and permits constant hygrometric exchange between the substrate and the environment – promoting high levels of living comfort and improving building health’. Joris Smet, Director of Smet Building Products Ltd


Choosing the right internal plaster can help improve indoor comfort in new buildings

Europeans spend at least 90% of their time indoors, and it’s well-known that indoor air quality has a major influence on the health, comfort and well-being of building occupants. For example, much has been written on how poor indoor air quality can been linked to Sick Building Syndrome, reduced productivity in offices and impaired learning in schools. We construct buildings ‘primarily as shelter from weather, providing us with security, living space, and privacy, for storage, and to live and work in comfort’.

As a result of the regulations for improved energy efficiency in new buildings as set by The Building Regulations 2010, the growth in Passive House buildings, and increased interest in healthier, more comfortable and ‘greener’ living environments, the variety of ‘breathable’ internal building components such as; insulation, render, plaster and paint has grown.  The rise and popularity of these type of products helps ensure the critical air-tightness – highly desired in the new building – is not hampered by poor water vapour permeability, leading to an unhealthy, or uncomfortable internal environment.

Thus, we need more effective solutions in building materials which can help maximise the internal comfort of our new buildings, while promoting ultimate energy efficiency, simultaneously trying to encourage exchange of outside and inside air – and doing it all in a sustainable way.


Complements the Passive House standard

It’s widely known that internal wet wall plasters contribute to achieving airtightness.  What is less well known is that choosing the right plaster can not only provide airtightness but can also can play a major role in improving internal environmental comfort by ensuring constant hygrometric exchange between the substrate and the environment. Smet Building Products Ltd, the agents for leading German manufacturer CASEA, introduce the latest in internal moisture regulating plasters: CASEA Casucalc Klima – Internal Base Coat Plaster and CASEA Klimafeinputz KFP – Breathable Fine Finishing Plaster.

Klimafeinputz KFP – Breathable Fine Finishing Plaster is unique in that rather than being a pure cement or pure gypsum-based plaster – it combines the properties of gypsum, lime and clay. The product’s special composition, consisting of clay, fine white lime, fractional sands, marble powder and CASUL® white pigment, allows the product to breathe and provides high level of protection against micro-organism/mould growth – without the use of chemical additives.

Sourced naturally and ecologically, the components of lime and clay combine for excellent technical properties; offering moisture absorption, moisture regulation, strength and protection against micro-organism growth.

Klimafeinputz KFP – Breathable Fine Finishing Plaster permits constant hygrometric exchange between the substrate and the environment.  It regulates moisture in the air – it’s highly breathable, therefore, contributing to humidity regulation – it works by absorbing moisture quickly and also by releasing it quickly.  Similarly, due to its natural chemical composition, it’s particularly alkaline – naturally preventing any mould growth, a property particularly important in the airtight envelopes of the newly built Passive homes.


Promoting high levels of comfort and improving building health

The plaster is extremely versatile and can be applied onto all common base coats such as; lime-cement, cement, gypsum, gypsum-lime, gypsum lime-clay and clay plastering renders, as well as onto plaster boards. The addition of CASUL® white pigment means the dried finished plaster has a very bright white colour – which is excellent news as painting is not mandatory, however, if a colour finish is required, and in order to facilitate maximum breathability when painting –  use compatible silicate, lime or clay-based paints.

CASEA Klimafeinputz KFP is a factory produced special white, mineral fine plaster CS I – according to EN 998-1 suitable for indoor use. It’s pre-mixed and supplied in ready to use 25kg buckets with a smooth finish.  The addition of the natural binders allows a long open time, ensuring the perfect finish is achieved.

Technically, it has an excellent bond to virtually any mineral substrate – therefore proving particularly suitable for new builds.  It’s very versatile for walls constructed out of low, medium and high-density blockwork and any other masonry substrate. As a finish Skim Coat, it’s ideal for final finishing of CASEA Casucalc Klima basecoat and CASEA Bauprotec renders and plasters where a smooth finish is required.  Being a strong plaster, it can be used in kitchens and bathrooms where tiling is required.

The special features dramatically improve the indoor living environment and are active throughout the lifetime of the plaster surface.  For use in kitchens, living rooms, student accommodation, hotels, conference facilities, sports facilities – or anywhere where a comfortable indoor ambiance is required.
