proPERLA® Water Repellent

Protect your roof while maintaining the original, natural look of the tiles.

Coatings incorporating silane resin technology have been available for over 25 years and are actually the fastest growing exterior coating systems in Europe. All this expertise has been combined with the latest technology. And the result is impressive!

Breathability

The tiles is able to breathe and will be permeable to water vapour. Air and moisture pass through from one side to the other. A breathing masonry will improve the thermal conductivity and insulation properties. Just a 5% content of damp in cavity wall insulation or other building materials can lower the thermal resistance by up to 50%.

Water repellent

You will recognise the excellent water repellent properties by its beading behavior. It will make the masonry dry and extremely resistant to biological hazards, mould, mildew,etc. A dry masonry will improve the thermal resistance, prevent frost damage and reduce the growth of microbial spores.

Self cleaning effect

Dirt particles are unable to obtain a hold on the proPERLA® coated facade and will simply flow off with rainfall. The façade remains clean and attractive, even on sides which are particularly exposed to the weather like on the north-facing side or facades in shade, as well as in areas with high air humidity or sea salt penetrated air.

The most expensive renovation is not always the best one.

The lifespan of a proPERLA® roof impregnation is at least 10 years. Its super hydrophobic properties have a direct impact on its many performance characteristics. Freezing water expands its size and frost damage occurs only if it is able to ingress in a wall. Water is not able to remain on a waterproof surface. Therefore no moss, algae, lichens and other microorganism can grow. Dirt particles are simply washed off with the next rain and the surface becomes self-cleaning. It will look clean and new at all times and no signs of deterioration will appear.

A clear insulation barrier

The masonry cream creates a clear insulation barrier for single skin buildings and those built with a cavity. It has been proven to help retain heat in walls and reduce heat loss.

A breathing surface will improve it’s insulation properties. Just a 5% content of damp in building materials can lower the thermal resistance by up to 50%. If a roof tile sealer cannot breathe, a build up of moisture will occur underneath the surface, leading to irreparable damage to roof tile.

FAQ: Water Repellent

With microFORMULA® technology the sealing of mineral surfaces is a breeze. This technology has been integrated in all proPERLA® systems of the last generation. With the 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.
