Application: Cerano is supplied pre-mixed in a bucket and applied and polished with a Stainless Steel trowel. It is applied in 2 very thin coats wet on wet, each 0.25mm thick. It is then worked as it dries to the desired finish. When dry it is sealed with 2 coats of Repel or Clearcote. Apply in temperatures above 5'C and below 35'C.
See Application video.
Preparation: Cerano can be applied over most common substrates such as cement sheeting, Gyprock, brick & block, and off form concrete. However it is a thin decorative render only so the substrate needs to be smooth and stable and properly prepared. This is generally done with a base coat of Polymer Render Grey or or ROCKCOTE Quick Render depending on the substrate, or primed with Ecostyle Sealer Undercoat with Grit if the surface is already smooth. Any base coats should be fully cured. ROCKCOTE will also prepare a custom specification for a specific project if requested.
