weberend aid is a polymer-modified cement and sand mix. The powder blend includes an integral bonding agent so that it requires only the addition of clean water on site.

Features and benefits

▲ Equalises suction on mixed backgrounds ▲ Provides excellent suction control across both high and low suction substrates ▲ Resists the penetration of external water to improve the weather resistance of rendering systems ▲ Quality controlled and factory blended to give a consistently high quality product ▲ Easy to apply by hawk and trowel and/or roller

● To achieve a good key for rendering onto smooth or otherwise unsuitable but sound surfaces ● Ideal as a pre-treatment for renderings required to resist severe exposure conditions ● Suitable substrates: dense concrete brickwork blockwork masonry clean, sound, well adhered existing render (<19 mm) Constraints Do not apply to gypsum plaster or previously painted surfaces. For applications where the codes of practice recommend sulphate resistance, use only the sulphate-resistant cement formulation.
