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.’
