Permarock Brick Effect Render
Permarock Brick Effect Render (BER) is a self-coloured polymer-modified cement-based render designed to simulate the appearance of brickwork. It is supplied as a pre-batched, two-coat system.
BER can be applied as the decorative finish coat of PermaRend Exterior Render Systems and Permarock External Wall Insulation Systems. In addition, it can also be used to create features such as soldier courses, brick quoins, etc. in conjunction with other decorative finishes.
Permarock Brick Effect Render incorporates a silicone water repellent that offers enhanced water resistance and helps to maintain a cleaner surface.
The render can be applied to suit metric or imperial brick sizes, and any bond pattern. It can also be used to create non-standard patterns and effects. Further aesthetic effects can also be achieved by varying the surface texture of the render, and incorporating special pigment powders into the render surface during application.

Method of Application
Permarock Brick Effect Render is a two-coat system comprising Permarock Brick Effect Render Base Coat (in the colour required for the brickwork joints – typically grey) and Permarock Brick Effect Render Top Coat (in the required brick face colour). Both materials are supplied as pre-batched dry powders, which require mixing with clean water on site.
The mixed and hydrated base coat material is applied onto the prepared substrate (reinforced base coat) by stainless steel trowel at a rate of approx. 10.8 kg per square metre to achieve a layer thickness of approx. 6 mm. The surface is levelled off and allowed to commence hardening / curing.
When the base coat has developed sufficient strength to support a further coat (the time required is dependent on temperature and relative humidity) the coloured top coat is applied at a rate of approx. 5.4 kg/m2. This produces a layer thickness of approx. 3 mm. The top coat is levelled and then textured using a brush, roller or other tool to create the required surface finish. Pigment powders can be applied onto the freshly levelled surface prior to texturing, if required.
The brick coursing is set out on the freshly rendered surface using string lines and levels, and then a special tool is used to cut through the top coat, whilst it is still wet but firm, to expose the base layer. The appearance of brickwork is achieved by cutting a pattern of horizontal and vertical lines, guided by pre-made templates.
Application / Drying Conditions
Permarock Brick Effect Render has a working temperature range of +5 °C to +30 °C. As with all cementitious materials, to avoid too-rapid drying, the material should not be applied during strong winds or under direct sunlight. Avoid application under high relative humidity conditions or if rainfall or frost / freezing temperatures are likely.
Drying times are dependent on temperature, ventilation and relative humidity. Protection from rain and frost should be provided for the first 48 hours after application, and surface condensation should be avoided to reduce the risk of efflorescence / lime bloom.
Packaging
The base and face layers are available in a variety of colours, and are supplied in 25 kg sacks.
