Surface preparation:

A thorough cleaning needed from dirt, dust and loose paints.
On old paint – sand well and clean with air pressure, clean with dry clean cloth soaked with thinner.
Iron Metals – recommended but not must – sand blast cleaning till white metal appears SA-2.5 level. Metal brushes clean -For rusty surfaces ST-3, for light rusty surfaces – ST-2.5, for galvanize steel – sanding until totally matte surface appears.
Very big surfaces –remove the paint with paint removers and wash with water for neutralizing. Sand/spray soft sands or plastic powder for light roughness. Rinse with water and dry completely.

Top color:

You can paint the top layer 8-12 hours after painting the primer if it had the heat and dryness condition.
During the cold winter, you can paint only after 24 hours.
The top layer can be “Denbergloss” aliphatic exterior polyurethane paint with UV resistance.

Instructions for use:

Open carefully parts A and B and stir separately.
Pour from two parts in the right ratio the required amount and mix well with mechanical mixer (operated by air pressure is recommended for safety reasons) for a uniform mixture.
Wait for 10 minutes while adding the thinner as needed and mix again. Spray a thick layer of 150-225 microns thickness 100-150 mic. dry film if no licks appear. If necessary if the layer does not completely uniform or part of surface not painted, wait about 4-12 hours for complete drying and spray another layer. Insert into clean and controlled temp. drying room for 12 hours before painting the top layer.
Wash the equipment well immediately after finishing painting.
