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. Acrylic premixed renders 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. Some of these premixed acrylic renders have a smoother complexion than traditional renders. There are also a wide variety of acrylic bound pigmented designer finishing coats that can be applied over acrylic render. Depending upon the product, they can be rolled, trowelled or sponged on. A limited number can also be sprayed on. Various finishes, patterns and textures are possible such as sand, sandstone, marble, stone, stone chip, lime wash or clay like finishes. There are stipple, glistening finishes, and those with enhanced water resistance and anti fungal properties. Acrylic renders take only 2 days to dry and cure - much faster than the 28 days for traditional render.
