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.

ProPERLA Exterior Facade Coating not only improves the appearance of the building, it helps to maintain and protect it in the long term too;

• It mimics the lotus leaf by creating a super hydrophobic, self cleaning surface. Dirt particles are unable to obtain a hold on ProPERLA treated surfaces and will simply flow off with rainfall.
• The growth of moss, algae and lichens is deterred.
• Helps to prevent discolouration.
• Slows the ageing or breakdown of the surface of the building by helping to protect it from the damaging effects of the weather including wind driven rain, frost, high air humidity and sea salt penetrated air.
• Performance is unaffected by UV rays.
• Colour stable

Masonry Crème

The invisible insulation barrier.

A surface treated with ProPERLA Masonry Crème will insulate mineral building materials by reducing water absorption. The product chemically bonds to the surface, penetrating up to 17mm to create an invisible insulation barrier.

• Creates a self-cleaning surface
• Manufactured in Germany using the very latest, superior technology
• Helps prevent salt efflorescence and sulphate attack
• Penetrates up to 17mm into the substrate to provide an invisible insulation barrier
• Discourages growth of moss, algae and lichens
• Prevents frost damage
• Proven performance

ProPERLA Masonry Crème creates an invisible 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.

UKAS accredited tests have demonstrated that by reducing water absorption of the walls, ProPERLA Masonry Crème 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 Masonry Crème 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 Masonry Crème.

ProPERLA Masonry Crème improves thermal efficiency and contributes to lower energy consumption and lower energy bills, by keeping walls dry. Damp walls act as ‘thermal bridges’ – enabling heat to transfer from the inside out twice as quickly as it would if the walls remained dry.

Independent testing has shown that ProPERLA Masonry Crème reduces water absorption by 96.3% and meets the British standard for water vapour resistance BS EN ISO 7783:2011.

By diminishing water absorption, ProPERLA Masonry Crème has been proven to reduce soluble salts migrating from bricks and mortar thereby preventing unsightly deposits of salt efflorescence. Whilst salt efflorescence is generally considered an aesthetic problem, it does have the potential to cause structural damage, such as the erosion of mortar joints, known as sulphate attack.

ProPERLA Masonry Crème does not alter the appearance of the building, it helps to maintain and protect the natural beauty of the masonry;

• It mimics the lotus leaf by creating a super hydrophobic, self cleaning surface. Dirt particles are unable to obtain a hold on ProPERLA treated surfaces and will simply flow off with rainfall.
• The growth of moss, algae and lichens is deterred.
• Slows the ageing or breakdown of the surface of the building by helping to protect it from the damaging effects of the weather including wind driven rain, frost, high air humidity and sea salt penetrated air.
• Performance is unaffected by UV rays

Keep the property clean and attractive

The superior technology mimics the ‘lotus-leaf’, repelling dirt and water to give a super hydrophobic effect, making walls/roof tiles self-cleaning.

• Dirt particles are unable to obtain a hold on ProPERLA treated surfaces and will simply flow off with rainfall.
• Helps to prevent discolouration and salt efflorescence
• Makes it difficult for the growth of moss, algae or lichens
• Slows the ageing or breakdown of the surface of the building or its tiles

The masonry and tiles remain clean and attractive, even where they are exposed to extreme weather conditions including shade, high air humidity or sea salt penetrated air. ProPERLA Water Repellent is completely unaffected by UV rays.

Wood Impregnator

Long lasting weather protection.

A one-coat super-hydrophobic advanced clear coating for vertical wooden surfaces. 10 year manufacturers guarantee.

• Dries clear, does not alter the appearance of the wood
• Highly breathable
• Creates a self-cleaning surface
• Helps prevent discoloration and rotting
• Discourages growth of moss, algae and lichens
• Extend the lifespan of the wood by keeping it dry
• Minimises shrinkage
• Proven performance

ProPERLA Wood Impregnator creates a super hydrophobic surface which keeps the wood dry.

A surface is considered super hydrophobic if a water droplet beads up (with a contact angle greater than 150⁰) and the droplets can slide away from the surface readily. Super hydrophobic surfaces repel water, causing it to form beads because it is more attracted to itself than the surface. This means water will run off the surface making it extremely difficult to wet.

This is known as the ‘lotus effect’ due to its similarity to the lotus leaf but is also seen on duck feathers and butterfly wings.

Wooden surfaces which have been coated with ProPERLA Wood Impregnator will respond in the same way – water will form droplets and won’t penetrate the timber.

Proven Performance

ProPERLA Wood Impregnator is water repellent in line with DIN 4108 (European rating for water repellency).

ProPERLA Wood Impregnator is weather resistant in accordance with VOB – meaning it can withstand all climatic conditions.

ProPERLA Wood Impregnator is tested and certified in accordance with EN 15824 : 2009, confirming the product’s performance with regard to water absorption, water vapour permeability, tensile strength, thermal conductivity and long term durability.
