Instructions for use

Quality/Preparation of Substrate

The concrete substrate must be sound and of sufficient compressive strength (minimum 25 N/mm2) with a minimum pull off strength of 1.5 N/mm2.The substrate must be clean, dry (surface humidity content <4%) and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc. Concrete substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and achieve an open textured surface. Local putting can be achieved with Epoxol® Putty in proportion from 1Α:1B to 2A:1B or Epoxol® Primer SF mixed with quartz sand.

Instructions for use

The surface must be dry (humidity limit=5%). In concrete surfaces when the moisture of the substrate is up to 8%, if there is not rising moisture and the substrate temperature is > +12°C the surface should be primed with water-based primer Acqua® Primer. (All epoxy primers can be used e.g.Epoxol® Primer, Neopox® Primer 1225, Neopox® Primer WS, Neopox®Primer AY depending on the needs and the substrate). Application: Apply 1 coating of Νeopox® CR with brush, roller or airless gun. If the 2nd layer will be applied after 24 hours, lightly scrub the surface to roughen it


Νeopox® CR cannot be applied below +12οC
Colour: Black

Cleaning of tools

Immediately after application with solvent Neοtex® 1021.

Stain removal

While still wet, with solvent Neοtex® 1021. If it has hardened, by mechanical means, in cases where it is possible, due to its great adhesion properties.
