Coatings, sealants & paints

For maintenance providers, the challenge has been to develop new applications that take into account these formulation changes

building, but until now the only way to get rid of it has been an expensive and inconvenient refurbishment, with no guarantee that more vandalism won’t occur immediately on completion of the project. However, thanks to sophisticated coatings which are applied in advance, spray paint and graffiti can now be removed from almost any interior or external surface. Passive fire protection in homes – especially multi-dwelling and high rise

properties – has understandably been in the media spotlight recently, and huge strides have been made in coatings to improve fire safety performance. Conforming to Fire Rating Class 0 is an obligation in certain premises such as Houses in multiple occupation (HMOs) but is also recommended in other buildings to help prevent flame spread.

COATINGS TO HELP HEALTH Another fast-moving area in coatings and paints is the use of light, colour, texture and finishes to improve life and work conditions. Scientific research has unequivocally shown that the way people engage with a building, positive or otherwise, can be directly affected by the colour and design of the space. The Equality Act Guidelines are designed to help avoid discriminating against people with disabilities, including visual impairment and dementia, concerns that are increasing against a backdrop of an ageing population. It’s now accepted that over 80 per cent of visually impaired people can discern

colour differences, so the use of contrast can make way finding and building navigation much easier – e.g. painting whole doors and architraves in a contrasting colour with the surrounding surfaces; making the skirting boards

the same or a similar colour as the wall gives visually impaired people an accurate indication of the size of the floor; using a colour that contrasts with the background draws attention to key features like switches, sockets and handrails. All of these developments mean that the features and benefits of paint now

extend far beyond ‘just a wall coating for a bit of colour’ and we can’t underestimate its potential benefits on health, well being and the protection of the UK’s housing stock.

Knauf is introducing a radical new render system, Knauf MineralAktiv, to the UK market. Designed to inhibit the growth of surface algae and fungi, the system addresses the most common problem associated with render finishes using a patented biocide-free composition. The clean contemporary aesthetics offered by render is a popular choice for specifiers, but the cool and often damp climate of the UK can quickly lead to disappointing discolouration because of the growth of algae and fungus on the surface. Some products tackle the problem by including biocides in the formulation, but this approach offers only a temporary solution as the biocide effect wears off over time. Knauf MineralAktiv, on the other hand, addresses the root of the problem by providing a naturally inhospitable environment. Fungus and mould both need damp and neutral PH conditions to flourish, so the formula of MineralAktiv addresses both of these issues. A long-lasting hybrid binder maintains high alkalinity for years while advanced moisture management works in combination with an IR absorber raising the surface temperature, increasing evaporation and limiting moisture on the render surface. These two characteristics ensure the finish remains bright and clean for years without the need for regular cleaning. Knauf MineralAktiv consists of a top coat and paint which can be used independently or in combination for maximum protection. Suitable for both new build and refurbishment projects, Knauf MineralAktiv is available in 230 colours.
