Priming
Priming is not normally required provided the substrate is sound, prepared and good quality non porous concrete. However, if concrete surface is porous, or w/c ratio is >0.5 it is recommended to use Vetoprime EP491. Vetoprime EP491 should be mixed in the proportions supplied. Add the entire contents of the hardener can to the base can. When thoroughly mixed, preferably using a slow speed mixer, the primer should be applied in a thin, continuous film using rollers or stiff brushes. Work the primer well into the surface of the concrete taking care to avoid ponding or over application. The primer should be left to achieve a tack-free condition before applying the top coat.

Mixing
In a separate mixing vessel, use a slow speed mixer to mix the base, hardener for 3 minutes. Mix these components in the quantities supplied taking care to ensure all containers are scraped clean. Do not add solvent thinners at any time. The first coat of Vetoproof EC720 should be laid using a short haired lamb wool roller, or squeegee to achieve a continuous coating. Ensure that loose hairs on the roller are removed before use. A minimum film thickness of 200 microns per coat should be applied for flooring system (this can be increased where specifi cations demand). The top coat can be applied in the same manner within 8 to 24 hours of the application of the top coat.

Application
The first coat of Vetoproof EC720 should be laid using a short haired lamb wool roller or airless spray equipment to achieve a continuous coating. Ensure that loose hairs on the roller are removed before use. A minimum film thickness of 200 microns per coat should be applied. Apply the second coat in a perpendicular manner to the first coat ensuring a minimum dry film thickness of 200 microns. It is recommended to use a different color for each coat to ensure complete coverage.

Cleaning
Tools and equipment should be cleaned with Vetonit Solvent XX400 immediately after use.
