A moderate strength render for moderate strength backgrounds and moderate exposure conditions. Benefits: weather resistant, allows walls to breathe, resists penetrating damp, will not chip, flake or peel, can be hosed down, tough and flexible, excellent adhesion. Uses: As a base coat render, it is applied in one coat, avoiding the drying time associated with multi-coat render systems. It can be used internally and externally. Universal Building Render resists the penetration of external water and has excellent weather resistance and durability, whilst also allowing the structure to breathe. Universal Building Render can be applied to most substrates including suitably prepared brickwork and concrete. Preparation: It is important that the correct grade of render is chosen to suit the substrate and application. All surfaces must be clean, dry and free from any material which may impair adhesion. Poorly keyed surfaces should be pre-treated with a suitable primer. Faults in the structure must be rectified before rendering. Mask around the areas where material is to be applied. This must be removed before the material has dried out. Note: In many cases rendering applied to expanded metal lathing is more prone to cracking than when applied to dense masonry. To reduce this risk, lathing must be fixed strictly in accordance with the manufacturer’s recommendations and relevant codes of practice. Expansion joints should be included as required.
This guide helps users effectively apply Bond It Universal Building Render. Ideal for both internal and external applications, this pre-mixed render provides a weather-resistant and breathable finish. Note that proper surface preparation is crucial for optimal adhesion and long-term performance.
