Wall Coating & Rendering

We cover Leicester & all surrounding areas

Designed to insulate bricks, masonry and porous building materials

Protecting your masonry for over 20 years…

Pro-Perla is a highly breathable paint coating

proPERLA® Insulation Creme has been developed with superior technology. It will create an invisible insulation barrier, penetrating deep into the substrate, up to 17 mm and protecting the masonry for over 20 years. It will protect your walls and its cavity from penetrating damp, improve their thermal resistance and reduce energy bills. proPERLA®’s Insulation Creme make walls and bricks self cleaning and allows the walls to breathe naturally.

Does the render on your property require rejuvenation or patching up?

Is it old and peeling away or has it lost its colour? Are the extremes in weather affecting the property and causing it to loose heat or damage the surface?

Vedi can offer a full or re-render of your property, removing the old cracked and damaged areas of the existing render and applying a new coat on either the front or all elevations of the property. Once the rendering has been set and inspected, we will return and spray with either coloured RENOTEC coating or a clear coat of Masonry Crème. proPERLA® Insulation Creme has been developed with superior technology. It will create an invisible insulation barrier, penetrating deep into the substrate, up to 17 mm and protecting the masonry for over 20 years. It will protect your walls and its cavity from penetrating damp, improve their thermal resistance and reduce energy bills. proPERLA®’s Insulation Creme make walls and bricks self-cleaning and allows the walls to breathe naturally.

proPERLA® Insulation Creme has been tested and certified to standards. The product penetrates deep into the substrate, creating an INVISIBLE INSULATION BARRIER that reduces water absorption by more than 95%. proPERLA® Insulation Creme has been tested according to EN ISO 15148:2002, demonstrating its hygrothermal performance on render, concrete, mortar, brick, and sandstone.

Before & After Pro-Perla Application

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.

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 highly breathable coating which helps to prevent penetrating damp.

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 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.

By diminishing water absorption, our clear masonry cream 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.

In contrast to our coloured exterior wall coating, the masonry cream 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

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

ProPERLA Masonry Crème is a one coat application system which can be applied by paint brush, roller or airless spray.

On application, the clear masonry cream is white but it will dry clear and will not alter the colour or appearance of the building. The porosity of the substrate dictates how long it takes for the protective masonry cream to dry clear.
