A technically advanced, two-coat coloured facade coating product for use on a range of substrates that require a coloured exterior wall coating. 10 year manufacturer’s guarantee and a lifetime expectancy of 25 years.
ProPERLA® Coloured Facade Coating is a flat, dirt-resistant and silicon emulsion based exterior facade coating for optimum protection against weathering.
ProPERLA® Coloured Facade Coating is technologically advanced and comes with a 10 year manufacturer’s guarantee.
Water-soluble, low film tension, weather resistant according to VOB, water repellent in conformance with DIN 4108, alkali resistant, highly permeable to water vapour, non-film forming, high hide, resistant to dirt and air pollutants and highly resistant to fungus, moss and algae.
When applied, ProPERLA® Exterior Facade Coating creates a super hydrophobic surface commonly referred to as the ‘lotus effect‘ due to it’s similarity to the water repelling properties of the lotus leaf. When it rains, coated mineral surfaces will repel the water, causing it to form beads (because the water is more attracted to itself than the surface) and run off without being absorbed. Independent tests have shown that it reduces water absorption by 93.4% and meets the British standard for water vapour resistance BS EN ISO 7783:2011
UKAS accredited tests have demonstrated that by reducing water absorption of the walls, ProPERLA Exterior Facade Coating lead to thermal performance benefits. It has been proven to meet ETAG 004;2011.
Testing in a hygrothermal chamber revealed that a wall coated in ProPERLA Exterior Facade Coating and subjected to repeated heat-rain conditions in accordance with ETAG 034:2012, resulted in reduced heat loss when compared with the uncoated (control) wall. The uncoated wall showed on average an increase of 6⁰C of heat loss in comparison to the walls coated with ProPERLA Exterior Facade Coating.
