Product preparation for application

Before opening the container, it is cleaned of impurities, to avoid contamination of the product.
The product is conditioned at 15 – 30°C.
Any skins formed on the surface are removed and the content is homogenized in order to perfectly redisperse any sediment.
Viscosity adjustment is done with diluent as follows:

Support preparation and application:
Preparation of unprimed/unpainted metal surfaces

Large deposits of grease, oil or dirt must be removed by a proven cleaning method, taking care that the deposit is removed and not spread over the surface.

Fats and oils are removed using solvents (white spirit, toluene), then cleaned with detergents or emulsified washing agents. The operation will be completed by rinsing with potable water and drying.

Degreasing by manual washing with solvents is not recommended because it leads to spreading a thin film of fat on the surface, a film that can affect the coating. Special attention will be paid to the edges and corners, the degreased surfaces must not be touched with the hand, as the perspiration contains salts.

Preparation of previously primed or painted metal surfaces

If the surface has been primed or painted before, completely remove the inappropriate layer of paint or primer and apply the steps and procedures indicated for unprimed surfaces.

Application conditions

Ambient temperature: 15 – 30°C
Relative humidity of the environment: max 75%
Support temperature: 15 – 30°C
Product temperature: 15 – 30°C
Do not apply to wet surfaces.
The rooms where the priming operation is performed will be free of dust, moisture, strong currents, and the surface to be primed will be properly lit.

Application details

The application can be done with a brush, roller or by spraying with air. The product can be diluted with STAR SOLV (Type 509), under manual or mechanical agitation, in order to obtain the viscosity recommended for each type of application.
Apply double layers on welds, corners and sharp edges.
When spraying, apply a wet layer in uniform, parallel passes. It overlaps
each pass ½ to avoid empty areas.
Uncovered, damaged areas or random pores are retouched with a brush.

Number of layers

It is recommended to apply two layers. Depending on the operating conditions or the color of the substrate, the number of layers may increase.
It is not recommended to apply thick layers, but several thin layers.
Recommended dry film/layer thickness
40 – 50 microns.

The application of the second layer is done at least 16 hours (at 23 ± 2°C) after the application of the first.
The drying time depends on the temperature and humidity (environment, support) and the thickness of the film.
The drying time is prolonged by the decrease in temperature and the increase in the thickness of the film. Poor room ventilation and excessive humidity also increase the drying time.

Maintenance of painting equipment

The equipment will be cleaned with washing solvents (white spirit or STAR
SOLV (Type 509) immediately after use. The product left in the equipment may cause it to block.

In the case of spray application, if the break is longer than 10 minutes,
the nozzle must be cleaned to avoid spraying defects.

Theoretical specific consumption

between 1-14m2/l/layer and varies depending on the absorption degree of the surface, color and method of application.
