ACRYLIC RENDER are modified cement based renders designed to provide weather resistant, decorative, render finishes, suitable for application over most building material substrates in interior and exterior wall and ceiling applications. Have superior water resistance and strength. They can be used on a wider variety of surfaces, including concrete, cement blocks, and AAC concrete panelling. With the right preparation, they can be used on smoother surfaces like cement sheeting, new high tech polymer exterior cladding such as Uni-Base, and expanded Polystyrene. A few of these require activation with cement just prior to application.
There are also a wide variety of premixed renders for different situations. Some have a polymer additive to the traditional cement, lime and sand mix for enhanced water resistance, flexibility and adhesion.
