What is Cement Render?
Cement Render is a three part composite. A mixture of clean washed Sydney/Newcastle sand, Grey general purpose cement and Hydrated plasterers lime. It is the traditional and oldest form of rendering and the typical choice when it come most domestic project applications.
What is Acrylic Render?
All acrylic render and textures are based on a homopolymer which is a plastic composite. The polymer and acrylic component makes the render much stronger, improving its elasticity, durability, and flexibility compared to sand and cement, minimizing cracking in areas of high movement.
What's better? Cement or Acrylic Render?
Depending on the circumstances of a project or the style of finish, both materials stand their ground in their respect. Acrylic Renderer is the industry standard for particular substrates which includes Foam Blocks, Hebel and Blue-board. Cement render and acrylic render can be used together to tackle a certain situation, as acrylic render built-in characteristics can cover over any substrate and cement render for its high-build and durable property.
What is Splatter (splash, slush, key) coat?
This is a three part composite material. A mixture of equal parts of Sydney sand, River sand, Grey general purpose cement and a bonding agent. This can be spayed on with a Tyrolean machine gun or flicked on using a trowel.
Can you Render over a pre-Painted surfaces?
Yes. A cement based Polymer modified adhesive base coat is applied prior to rendering. Rockcote and MAC are the leading names in special acrylic systems offering their own version of these materials. Check out: Rockcote Keycote and MAC HBS
Can you Render over Sandstone?
Yes. A few coats may be applied depending on the undulation of the sandstone. Firstly a splatter/key coat is applied directly onto the sandstone and allowed to cure. Sheets of expended metal may be used if the undulated surface of the sandstone requires more the 25mm each time. The process is repeated until the wall is straightened and plumb depending on the projects specifications.
Can you Render over Drywall ?
Yes. Drywall commonly known as Gyprock can be rendered but with the maximum of 1-3mm minimising weight to the drywall. Polymers and acrylics are the recommended applicants due to there light-weight, elasticity and their tight coating application systems. Decorative plaster (venetian) can be applied over drywall given the proper preparations.
Can you Render over Tiler's Glue?
Yes. A cement based Polymer modified adhesive base coat is applied prior to rendering. Rockcote and MAC are the leading names in special acrylic systems offering their own version of these materials. Check out: Rockcote Keycote and MAC HBS
