SURFACE PREPARATION
The surface must be dry and clean of dust and other debris and cleaned with Kraft Brush Thinner. Remove all loose or peeling paint. Painted surfaces should be sanded with the appropriate sandpaper to obtain a dull finish. Wet sanding is recommended wherever possible to avoid dust build-up and exposure to it.

“On new metal surfaces: Before applying paint, for rust protection, apply 1-2 coats of Kraft Rust Blocker or Kraft Minio and optionally 1 coat of Kraft Metal Primer.
“On galvanized or aluminium surfaces: first apply 1-2 coats of Kraft Multi Primer and allow to dry for 24 hours.
“On already painted metal surfaces: Check the stability of the paint. Remove all residues of old paint and directly apply 2 coats of Kraft Hard Duko Classic.
