Ronabond Security Coating is a prepacked fairing coat mortar which is applied as a skim coat in thicknesses up to 3mm to provide a smooth, hard finish to damaged, blemished and repaired concrete surfaces. Ronabond Security Coating is used as a levelling mortar prior to the application of protective coatings and paints. It can also be used to give a “harder than plaster” finish to walls in, for example, prisons and detention centres. The material is supplied in preblended form which can be mixed by hand or machine in small lots. Application is by trowel or brush. The surface should be sponge or tight trowelled for a smooth finish before dry. It is recommended that for aesthetics reasons only Ronabond Security Coating is covered with a protective and/or decorative coating such as Ronabond Joltec or Ronabond Zolpacryl.
