Protäck V

Waterborne, semi-matte, and quick-drying metal paint for roofs >15° slope and exterior facades.

Used as a topcoat on untreated or previously painted galvanized steel and sheet metal surfaces, industrially coated sheet metal surfaces – coatings of polyurethane, PURAL, PUREX, polyester, acrylic, and aged PVC plastisol. (Not suitable for PVF2-type sheet metal).

The paint should be thoroughly stirred before use. The paint can be thinned if necessary with 5 – 15% by volume of water.
Avoid painting in direct sunlight or when there is a risk of dew or rain.
New unpainted surfaces: Apply Protäck V with a brush, roller, or spray (e.g., Wagner PS 3.29 airless with a suitable nozzle). Apply at least two coats. (Minimum 120µm dry). Three coats provide an even more effective long-term protection.

Maintenance painting: After cleaning and removing loose paint, simply spot-paint the stainless steel surface with Protäck V. Rusty, cleaned steel surfaces are primed with Hagmans Plåtprimer up to 2 times depending on the amount of rust. The roof is repainted with Protäck V to approximately 120 µm dry film thickness.

Before painting, surfaces must be dry, solid, and thoroughly cleaned of dirt, loose paint, and grease, and an adhesion test must be performed according to the cross-cut method. Surfaces are washed with Hagmans Painter’s Wash Roof/Facade. Oxidized galvanized surfaces are treated with Hagmans Pickling Solution. Rusty surfaces are cleaned by sandblasting or mechanical steel brushing. Thereafter, the previously rusty surfaces are primed once or twice (depending on the degree of rust) with Hagmans Sheet Metal Primer. Aluminum surfaces are etched and primed before applying paint. If the substrate temperature is higher than 40°C, the application and adhesion are impaired. Pores or bubbles may appear in the paint film.
