Exterior Brick Stone Cleaning & Coating
Extreme Climate ONE COAT water seal stops penetrating damp using the latest fluorocarbon technology to create
simply the best performing (100% breathable) brick and stone sealer available today. With a lifespan of up to 10
years and no surface darkening, this formula halts rainwater absorption offering truly exceptional hydrophobic or
"bead up" water repellency. Kingfisher Approved contractors can offer a 10 year re-pointing guarantee,
incorporating Extreme Climate, Kingfisher pointing mortar and pointing solution.
Extreme Climate water seal prevents damaging moisture ingress which causes masonry to spall in the freeze /
thaw cycle and inhibits moss growth by robbing it of water and nutrients drawn from damp mortar. Using "Extreme
Climate" to dry out a damp wall can also reduce thermal loss by up to 30% because a wet wall is a cold wall and
"bleeds" heat to the atmosphere at an accelerated rate.
Drying out the wall with Extreme Climate also reduces the problem of condensation and black mould, which
develop on the indoor side of exterior walls when rain saturation cools the wall temperature such that warm moist
indoor air condenses on the cold surface
Extreme Climate water seal also helps to keep buildings clean by forming an effective barrier against airborne dirt
and other contaminants, which would otherwise be dissolved by rainwater and leech into the substrate where they
inevitably stain the surface.
‣ Stop penetrating damp with our 100% breathable brick & stone sealer
‣ Lasts up to 10 years
‣ Reduce thermal loss by up to 30%
‣ Reduces condensation & black mould
The ultimate clear waterproof paint & protective masonry cream. A surface treated with masonry cream will insulate mineral building materials by reducing water absorption. The
masonry cream chemically bonds to the surface, penetrating up to 17mm to create an invisible insulation barrier.
Key features of our masonry cream include:
For use on a range of substrates including brick, stone, concrete and sandstone
Manufactured in Germany using the very latest, superior technology
It has undergone UKAS Accredited testing
Verified by the Energy Saving Trust
One-coat masonry protection cream
Penetrates up to 17mm into the substrate to provide a clear insulation barrier
Chemically bonds to mineral surfaces
Dries clear, it does not alter the appearance of the substrate
Super hydrophobic coating
Creates a self-cleaning surface like the Lotus Effect
Helps prevent salt efflorescence and sulphate attack
Helps prevent discoloration
Discourages growth of moss, algae and lichens
Prevents frost damage
BRICK and STONE CLEANING & SEALING
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.
UKAS accredited tests have demonstrated that by reducing water absorption of the walls, our masonry cream
lead to thermal performance benefits. It has been proven to meet EAD 040083-00-0404. In addition, testing in
a hygrothermal chamber revealed that a wall coated in the masonry cream and subjected to repeated heat-
rain conditions in accordance with EAD 090062-00-0404, 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.The clear coating 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 our masonry cream 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 sealer products, it does not block the pores of the masonry by coating them with a
thin film. Therefore, the product is a breathable masonry paint which helps to prevent penetrating damp.
Super Hydrophobic Coating
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
Substrates coated with the protective masonry cream 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.
ProPERLA Masonry Crème has undergone independent tests by UKAS certified body Lucideon
and has been proven to meet the following standards;
EAD 040083-00-0404 – 25 year hygrothermal performance
EAD 090062-00-0404 – external thermal insulation composite
BS EN ISO 7783 – 2011 – water vapour diffusion
BS EN ISO 12572 – water vapour resistance
20 Year Product Guarantee
ProPERLA Masonry Crème benefits from a 20 year manufacturer’s guarantee but has been
proven to perform for 25 years. When tested under 25 years accelerated weathering conditions
there was no deterioration in performance or aesthetic appearance.
