Detailed Installation Guide


The surface of the masonry that is to be restored must be thoroughly cleaned of all existing paints, coatings, dust, and other impurities prior to any application. Previous renders, plasters and the like must be removed up to a height of 300mm above the level of the ‘salt line’, or 1 metre above the original DPC, whichever Is the higher of the two.

Where necessary, the mortar of both vertical and horizontal joints must be scraped out to a depth of about 2cm. Any damaged and defective areas of substrate (such as damaged bricks and stones) must be replaced.

In extreme cases, where a wall needs to be re-profiled before application, it should be done with a suitable mortar. Prior to application of the BR-Bond, the surface must be cleaned with pressurised air or a steel wire brush. Where the existing substrate contains an excessive build-up of salts it is advisable to take samples to determine such things as the moisture content of the brickwork, the salt content etc. This may then help with determining the optimum thickness of the restoration rendering system.


The dry mix should be mixed with clean water. Small amounts of the render can be mixed in a pail with an electric drill fitted with a mixing paddle. Larger amounts should be mixed with a conventional mixer. Water consumption is typically 4 to 5 litres per 1 No. (25 kg) bag of product.The mixing time is typically 10 to 15 minutes. Addition of binders or other components to the mix are not advisable. Working time at 20°C is typically 60 minutes. Neither the temperature of the substrate, nor temperature of the ambient air shall be below + 5 °C or above + 30 °C during the application process.


The material is applied manually. The BR-Bond should be applied in a thin layer not exceeding 5mm thickness, either in the shape of crosses, or in dabs. The application should not cover more than 50% of the area being treated. Covering the entire area is not recommended.


The application should be protected from direct sunlight, wind, and other factors which could result in excessive evaporation.
