This unique roof impregnation technology makes roof tiles self cleaning, extremely water repellent and allows the roof to breathe naturally.
RENOTEC® ROOF COATING is scientifically developed by specialised engineers, which have more than 30 years of experience in developing high quality protective coatings for the roofing industry. Treatments with RENOTEC® will extend the lifetime of roof tiles and minimize further surface erosion. It has been developed to transform roofs from dirty and unattractive to clean and shiny.
The excellent hydrophobic properties will make your roof dry and extremely resistant to biological hazards, mould, mildew,etc. Dry roof tiles will improve the thermal resistance, prevent frost damage and reduce the growth of microbial spores.
Dirt particles are unable to obtain a hold on a roof coated with RENOTEC® and will simply flow off with rainfall. Your roof tiles will remain clean and attractive for many years
RENOTEC® ROOF COATING is the leading roof coating system in Germany, engineered to improve roofs to resist weather influences caused by rain, frost and sun. It is based on a special organic 100% acrylic formula (free of APEO) and contains specially selected pigments.
Roof Coating
Roof Coating with excellent properties.
All approved applicators have undertaken specialised training by ProPERLA in order to fully understand the highly technical properties of the exterior coatings and the correct procedures for pre-application and application.
By choosing an approved applicator, you are ensuring optimum performance of the ProPERLA exterior coating and the manufacturer’s guarantee is safeguarded.
With microFORMULA® technology the sealing of mineral surfaces is a breeze. This technology has been integrated in all proPERLA® systems of the last generation.

The ProPERLA range of exterior coatings have been designed to be highly breathable to ensure that they do not interfere with a substrate’s natural ability to ‘breathe’ even after coating.
Unlike some stone and brick sealing products, it does not block the pores of the masonry by coating them with a thin film.
Water vapour permeability testing was conducted in accordance with BS EN ISO 7783:2011 and it demonstrated that the coating had little effect on the water vapour diffusion of the substrate.
As moisture is naturally drawn to the surface of the brick or substrate, ProPERLA coatings allow the water molecules to pass through and release into the air – avoiding complications of trapped water and moisture which will ultimately lead to damp problems.
‘Breathability’ is a term used within the building industry to describe how a substrate allows water molecules and air molecules to pass through it. Breathability ratings are identified by an ‘SD’ value –both ProPERLA Masonry Crème and ProPERLA Water Repellent have an SD value of 0.00, whilst ProPERLA Exterior Façade Coating (Colours) has a rating of 0.06. These figures show that the products are at the top end of breathability ratings.
Yes they do – the products bond with the substrate and will prevent further damage or surface breakdown.
ProPERLA cannot be applied in temperatures less than 5°C.
Years after proPERLA® came on the market, we decided to introduce a roof and tile paint to the proPERLA® range. At that time, another of our brands, RENOTEC®, was (and still is) very popular in Europe, so we decided to keep RENOTEC® as a unique roof and tile paint in order not to create two equal product lines.
