Installation Guide


The surface must be clean and free of dust and other impurities. If bonding is a concern, then the surface must be treated with a coat of Freezteq BR-Bond.

Any defective wall finishes must be removed to a minimum height 300mm above the level of the ‘salt line’, or 1 metre above the original DPC, whichever is the higher of the two. The mortar of both vertical and horizontal joints must be scraped out to a depth of about 2cm. Any damaged or defective areas of the substrate (such as damaged bricks or stones) must be replaced. Damaged surfaces should be reprofiled.

The area should then be cleaned with compressed air or with a steel wire brush.


The Freezteq BR-Base can be mixed in small amounts with an electric drill fitted with a mixing paddle. Larger amounts should be mixed with a conventional mixer. Water consumption is typically 9 – 10 litres per 1 No. (25kg) bag of product.

The mixing time should be a minimum of 10 minutes. (Typically, mixing time is between 10 and 15 minutes). Allowing the mixture to rest for approximately 3 minutes part way through mixing is best practice. Mixing for periods longer than 30 minutes should be avoided because of the risk of over-mixing. At lower temperatures, the mixing time may have to be extended.

The working time of the mix at 20°C is typically 60 minutes. Neither the temperature of the substrate base, nor the temperature of the ambient air, shall be below +5 °C or above +30°C during the application process.


Application of the Freezteq BR-Base may be undertaken manually, or with a plastering machine, installed in layers of between 15mm – 20mm thick. When applying the render in several layers, the first coat should be rendered so that the surface is coarse, thus ensuring a key for the subsequent coat. This can be achieved by using a stiff brush. Before applying any further layer, the previous layer must be allowed to dry.

Freezteq BR-Base should be finished with Freezteq BR-Finish.

When the next layer is to be Freezteq BR-Finish, the layer receiving the Finish coating should be rendered so that the surface is open, flat and not polished.


The render should be protected from direct sunlight, wind and other factors which could result in excessive evaporation. Under extreme conditions the render should be moistened.

Please Note

Standards may vary from region to region. The user should make contact with their local approval body prior to carrying out any work so as to ensure they are fully compliant with any standards that are enforce.
