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.
Reduce Heat Loss & Energy Bills
Keeping walls dry reduces heat loss and contributes to lower energy consumption and lower energy bills. A damp content of 5% in a plain brick wall can lower the insulation by up to 50%, especially where cavity wall insulation has been installed.
ProPERLA Masonry Crème is an external super hydrophobic coating which improves thermal efficiency by reducing water absorption by more than 95%. Tests have demonstrated that when applied to clay bricks, it slows down thermal heat loss by up to 76.83%.
ProPERLA Masonry Crème chemically bonds to mineral building surfaces, penetrating up to 17mm to create an invisible insulation barrier.

Prevent and Protect
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
Water cannot stick to the coated surface but forms droplets that run off the surface.
Water and moisture are able to escape the masonry due to the high breathability rating of the products.
Masonry remains clean and attractive as dirt is unable to take hold.
Reduces water absorption by more than 93%. Dry walls mean less heat loss.
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.
ProPERLA Masonry Crème does not restrict the ability of the building to breathe. 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.
Application of ProPERLA Masonry Crème protects the walls and cavities by keeping them dry whilst allowing air and moisture to escape. It maintains the important capability of the building envelope to breathe. Unlike some stone and brick sealing products, it does not block the pores of the masonry by coating them with a thin film.
A surface is considered super hydrophobic if a water droplet beads up (with a contact angle greater than 140⁰ and the droplets can slide aware from the surface readily (it has a small contact angle hysteresis). 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.
Substrates coated with ProPERLA Masonry Crème will respond in the same way – water will form droplets and won’t penetrate the substrate. Independent testing has shown that it reduces water absorption by 96.3% and meets the British standard for water vapour resistance BS EN ISO 7783:2011.
