HOSTAGRUND RUST BLOCKER U2161

Solvent-based one-pack impregnating primer curing by moisture uses on metal, both exterior and interior. It ensures topcoat adherence on difficult surfaces (metal with rest of rust, light metals). The paint is highly effective in humid environment, where other fails, especially: underground collectors, metal tanks, pipes, roof and bridge constructions. It is also suitable for penetrating of porous and less coherent surfaces as concrete, masonry and wood. Cured paint has proper chemical resistance.

BENEFITS

- Application in humid
- Blocks corrosion
 - Adhesion on rust

SURFACE PREPARATION

The surface has to be clean, dry and free of grease, rust and dust. Previously painted surfaces clean, degrease and remove all poorly adhering old coats to the solid surface when renovate. Verify compatibility between old paint and new one. Perform a test on the area 1 m².

Thinner: BALTECH S6005 for cleaning tools

Spreading capacity: 15 – 21,5 m2/1 liter per one layer

WORKFLOW

Properly mix before use. Don´t thin for brush and airless applications.
Apply 1-2 coats of HOSTAGRUND RUST BLOCKER U2161 for total dry film thickness 10 µm. Second coat apply in 2-3 hours of drying (20 °C, humidity 50-98 %). Porous materials coats immediately after the soak.
Than the technological break from 6 to 48 hours is necessary according conditions (the smaller film and the higher temperature and humidity, the shorter curing time and the technological break).
Apply 1-2 coats of FORMEX PRIMER FOR GALVANIZED IRON S2003 in total film thickness 40-80 µm. Apply 1-2 coats of INDUSTROL PROFI U2129 in total film thickness 40-80 µm.
